Harry Potter and the Half-Blood Prince (film)

Harry Potter and the Half-Blood Prince is a 2009 film based on the sixth novel by J. K. Rowling. It is the sixth film in the Harry Potter film series. David Yates, the director of the fifth film, Harry Potter and the Order of the Phoenix, directed. David Heyman and David Barron produced, and Steve Kloves, though he did not write the fifth film, has returned as screenwriter for this installment. Filming began on September 24, 2007. The film was released in the UK, Canada and US on July 15, 2009 in regular theatres, and an IMAX 3-D release on July 29, 2009. Unlike the previous film, the sixth film was released in regular theaters on July 15 and IMAX 3-D on July 29 because of the IMAX release of Transformers: Revenge of the Fallen. The film has was chosen to be screened at the Royal Film Performance on November 17, 2008, but due to the date of release pushed back, it was not shown. On January 2, 2009, the film received a PG rating in the USA. On July 7, 2009, at the world film premiere of Harry Potter and the Half-Blood Prince in London, the cast and crew all wore white ribbons in memory and tribute of 18-year-old British actor and co-star Robert Knox. Knox, who played Marcus Belby in the movie, was stabbed to death on May 24, 2008.

Synopsis
''Voldemort is tightening his grip on both the Muggle and Wizarding worlds and Hogwarts is no longer the safe haven it once was. Harry suspects that dangers may even lie within the castle, but Dumbledore is more intent upon preparing him for the final battle that he knows is fast approaching. Together they work to find the key to unlock Voldemort's defenses and, to this end, Dumbledore recruits his old friend and colleague, the well-connected and unsuspecting bon vivant Professor Horace Slughorn, whom he believes holds crucial information. Meanwhile, the students are under attack from a very different adversary as teenage hormones rage across the ramparts. Harry finds himself more and more drawn to Ginny Weasley, but so is Dean Thomas. And Lavender Brown has decided that Ron is the one for her, only she hadn't counted on Romilda Vane's chocolates. And then there's Hermione, simmering with jealously but determined not to show her feelings. As romance blossoms, one student remains aloof. He is determined to make his mark, albeit a dark one. Love is in the air, but tragedy lies ahead and Hogwarts may never be the same again.''

Development
Before David Yates was officially chosen to direct the film, many others had been offered the job, and previous directors had expressed an interest in returning. Alfonso Cuarón, the director of the third film, stated he "would love to have the opportunity" to return. Goblet of Fire director Mike Newell declined a spot to direct the fifth film, and was not approached for this one either. Terry Gilliam was Rowling's personal choice to direct Philosopher's Stone. However, when asked whether he would consider directing a later film, Gilliam said, "Warner Bros. had their chance the first time around, and they blew it."

Yates has retained composer Nicholas Hooper, costume designer Jany Temime, visual effects supervisor Tim Burke, creature and make-up effects designer Nick Dudman, and special effects supervisor John Richardson from the fifth film. Since February 2007, Stuart Craig, the production designer of the first five films as well, has been designing sets, including the cave, and the astronomy tower, where the climax of the film takes place. Academy Award nominated Bruno Delbonnel is the film's cinematographer.

Yates and Heyman have noted that some of the events of Harry Potter and the Deathly Hallows may influence the script of the film, and that there will not be as many memories in the film as in the book. Yates noted: "We're making a decision right now to compress those a wee bit, but we've still got some really cool ones." . Steve Kloves, who wrote the first four films, returned for the sixth adaptation. Rowling has read Kloves' script and crossed out a passage in which Dumbledore recalls a past female love, penning in the margin "Dumbledore is gay."

Filming
Filming began on September 24th, 2007, with one week of rehearsals, and principal photography ended May 2008. Some sources stated that filming may move from the UK, where all of the previous five films have been shot. This is North Scotland reported filming will take place in New Zealand, due to the "more agreeable economy and climate" and lack of Scottish funding. The Sunday Business Post in Ireland has noted that the film's producers and WB executives have been scouting there, specifically Leinster and Munster because they "believe they have now exhausted possible locations in Britain." They are "particularly keen on Ireland, as the landscape is similar to Britain and will appear similar to the settings of the previous films." The crew also scouted around Cape Wrath in Scotland, for use in the cave scene. Filming is scheduled to return to Glen Coe and Glenfinnan, both locations that have appeared in the previous films, to preserve the continuity of the landscape.

On the weekend of October 6th, 2007, the crew shot scenes involving the Hogwarts Express in the misty and dewy environment of Fort William, Scotland. A series of night scenes have been filmed in the village of Lacock and the cloisters at Lacock Abbey for three nights starting 25 October 2007. Filming took place from 5 p.m. to 5 a.m. daily, and residents of the street were asked to black out their windows with dark blinds. On set reports indicated that the main scene filmed was Harry and Dumbledore's visit to Slughorn's house. Further filming took place in Surbiton railway station in October 2007, Gloucester Cathedral, where the first and second films were shot, in February 2008, and at the Millennium Bridge in London in March 2008.

Though Radcliffe, Gambon and Broadbent started shooting in late September 2007, some other cast members started much later: Watson did not begin until December 2007, Rickman until January 2008, and Bonham Carter until February 2008. Principal photography wrapped up on May 17 2008. And a confirmation that editing was complete was released on July 29, 2008, though we do not know when they finished exactly.

On January 6th, 2008, websites reported that the movie had been rated "PG" by the MPAA, for scary images, some violence, language and mild sensuality. This is the first time since the third movie that a Harry Potter film has been rated PG, although in Britain it is a 12A.

The Trio

 * Daniel Radcliffe as Harry Potter, who is now entering his sixth year at Hogwarts, with the wizarding world at war.
 * Rupert Grint as Ron Weasley, Harry's best friend. He develops a relationship with Lavender Brown and later with Hermione Granger.

Hogwarts Staff

 * Alan Rickman as Severus Snape, the former Potions master, who finally achieves his goal of becoming Defence Against the Dark Arts teacher.

Movie Posters and Banners
Apparently both versions have emerged of the first 2 posters. In which we see is the text "Coming Soon", while others displayed the text "07/17/09." SnitchSeeker.com has just released the third poster in high resolution. It preview Harry, with Dumbledore's reflection in his spectacles and "HP6" in the lower right hand corner, a style not seen before on any of the films promotional posters.
 * Since the 5th of February 2009, Three Official Teaser Posters for the movie has been circling in the world wide web.


 * In August 2008, the website ScienceBlogs.com posted eight unofficial "Half-Blood Prince" movie posters. The posters seemed genuine and many website used them as promotional tools. Those images can be view here, here.

1. The Other Minister

 * The Millennium Bridge collapses in the beginning of the film, and is shown to be caused by three flying Death Eaters. The scene with Scrimgeour and the Muggle Prime Minister is omitted.
 * The first chapter, where Cornelius Fudge recaps all the bad things that have happened to the muggle Prime Minister, has been omitted. It also explains how Fudge resigned as Minister for Magic and how Rufus Scrimgeour took office, as well as describing the murders, hurricanes, and bridge collapses that have been going on. However, there is still a minor reference in the Daily Prophet at the beginning of the film that mentions there is a new Minister for Magic.
 * Harry has a copy of the Daily Prophet in the Muggle world. He reads it while in a café located along Surbiton station, then leaves it on the table when he sees Professor Dumbledore outside. The muggle waitress at the café flirts with Harry and asks about the newspaper he reads, which is not included the book.

2. Spinner’s End

 * The Spinner's End film location is consistent with the book. The mill referred to in the text is not a watermill or windmill, but a nineteenth-century textiles factory in a northern industrial town in the UK, most likely in Lancashire or West Yorkshire. The text references the mill chimneys (now disused) and rows of nearby houses. Terraced houses as shown in the film are typical of late nineteenth century mill-workers houses in industrial Britain.
 * When Narcissa and Bellatrix go to meet Snape, Bellatrix does not show the intense loathing for Snape that she does in the book and does not press him to answer questions about his allegiances. Narcissa does not seem as grief stricken as one might expect—she does, however, have tears in her eyes—and is not the one who suggests the Unbreakable Vow. Her hair is a mix of blonde and dark brown stripes, rather than being completely flaxen blonde. Snape also seems reluctant to make the vow, instead of immediately agreeing as in the book.
 * Peter Pettigrew a.k.a. Wormtail's role is smaller than his in the book. In the film, he peeps out of the door to greet Narcissa and Bellatrix, and in the next shot, after showing the two into the parlor room, where Snape is waiting, Snape uses his wand to slam the door shut, barring Pettigrew from the room.

3. Will and Won't

 * The scene with the Dursleys when Dumbledore comes for Harry at Privet Drive as he had pre-arranged in a letter has been omitted. Rather, Dumbledore finds Harry in a train station restaurant. The Dursleys do not appear in the movie.
 * Harry is never mentioned to have inherited Grimmauld Place or Kreacher.
 * House-elf Kreacher is also omitted in the entire movie.
 * There is no sign of any pamphlet showing the Safety measures issued by the Ministry.

4. Horace Slughorn

 * The entire village of Budleigh Babberton is recreated from the book, including the old war memorial. There is a pub called Babberton Arms in the background.
 * Dumbledore does not give Harry the heads up about Slughorn by mentioning that they are short on staff or alluding that he needs his assistance. They just go to the Muggle house where Slughorn is hiding. Harry does not speak to Slughorn of what he stands to gain by returning to Hogwarts.
 * Safety measures issued by the Ministry and about the Inferi were not discussed throughout the entire film.
 * In the book, the flaw in Horace Slughorn's plan to hide himself was that he forgot to cast the Dark Mark. In the film, the flaw is the blood on the ceiling, which Dumbledore identified as Dragon blood.
 * In the book Horace Slughorn was said to have a big silver moustache like a walrus and was supposed to be quite large, both are changed for the movie.

5. An Excess of Phlegm

 * Dumbledore does not inform Harry, before leaving him at the Burrow, that he will be giving him private lessons and does not tell him to confide the truth about the prophecy to Ron and Hermione or to keep his invisibility cloak with him at all times.
 * Instead of Dumbledore and Harry apparating to the tool shed near the Burrow, Harry finds himself standing on the swamp alone outside the Burrow.
 * In the film, Ginny is the first one to notice Harry, in the book Molly Weasley and Tonks see Harry first. Security measure before entering the Burrow is not implied in the film.
 * In the film, it is implied that Harry already likes Ginny when he looks dreamily at her in her bedroom window before entering the burrow.
 * Discussion of Bill and Fleur's wedding arrangements, Fleur's stay at the Burrow, and even both characters, have been omitted.
 * The relationship between Tonks and Lupin is implied, as they leave the party together and Tonks mentions that "the first night of the full moon cycle is always the worst." She also calls Remus sweetheart but later in the film. In the book, she was presumably discussing her feelings for and worries about Lupin with Mrs. Weasley before Harry arrives. Tonks does not appear on this chapter in the movie.
 * Harry, Ron, and Hermione sit around a levitated smoldering wad of the Daily Prophet discussing about Dumbledore, which seemed to be ignited by Harry with his wand. This does not happen in the book and could not because Hogwarts students are not allowed to use magic outside of school. Though, as pointed out later in the book, the trace can only identify that magic has been used, so in magical households in is up to the parent to enforce the rule.
 * There is no scene where the Owls bring the examination results; the first reference to Harry's exam results comes when Professor McGonagall informs him (in the Hogwarts corridor) that he may take potions as he had exceeded expectations in this subject.

6. Draco's Detour

 * Diagon Alley is almost completely boarded up and vacated. The only life to be seen comes from Weasleys' Wizard Wheezes Joke Shop. The "U-No-Poo" posters are not mentioned. However, there is a statuesque, moving sign of a typical Muggle-like magician lifting a top hat to reveal a rabbit. The sign is over a story tall.


 * There is no mention of how the Weasley's were able to open the store because of the winning prize of the Triwizard Tournament held two years before.
 * The scene where the trio meets the Malfoys in Madam Malkin's (and promptly fight) is neither shown or mentioned.
 * In the book, when Ron asks his brothers for a discount at Weasleys' Wizard Wheezes, Fred and George knock one knut off the price of his merchandise. In the film, they double the price from five galleons to ten.
 * Draco does not sneak off on his own and talk to Mr. Borgin about fixing the cabinet, but instead goes with his mum and several Death Eaters. Harry, Ron, and Hermione do not follow him under the cloak and use extendable ears, and Hermione does not try to trick Mr. Borgin into telling her what Draco is reserving.
 * Borgin and Burkes appears with a sign without the 's' at the end of Burkes. There is a WANTED poster of Fenrir Greyback in Knockturn Alley. The trio climbs the dilapidated roof of an abandoned building to witness Draco being shown one half of the pair of vanishing cabinets, instead of listening to Malfoy about wanting to fix something, from the beginning they know that the object that Draco wants is the vanishing cabinet, the cursed necklace is not mentioned nor seen. The cabinet is triangular-shaped and monolith in size.
 * There is no mention of fake amulets, etc. being sold, or of Mr. Weasley's promotion.

7. The Slug Club

 * The Slug Club's first meeting does not take place at Slughorn's compartment in the Hogwarts Express, but at Slughorn's office in Hogwarts.
 * The Slytherin end of the Hogwarts Express is split into two sides, not compartments as had been seen in previous films. It looks like booths with a table in between them. There is no door to close as had been in previous films. The compartments where Harry, Ron, and Hermione sit are similar to what was in previous films, with the sliding doors.
 * The Hogwarts Express is shown to have five coaches, instead of the usual four coaches as shown in the previous books.
 * Students move from the train to the school without school robes, rather clad in modern clothing.




 * The scene in which Draco catches Harry spying on him on the train is preformed verbatim from the book, however Luna Lovegood, not Tonks, finds Harry with her Spectrespecs, and states she can see Wrackspurts all over him.
 * What Draco reveals on the train is far less suggestive in the movie.
 * Harry Potter is not met at the gate by Snape. Instead, Professor Flitwick stops Harry and Luna and then casts a non-verbal spell to the gate for defence.
 * Because Nymphadora Tonks was replaced by Luna in saving Harry from the train, The movie does not show Tonks' Patronus.

8. Snape Victorious

 * Snape does not take Harry to the castle; instead, Harry and Luna walk by themselves.
 * Hagrid is present in the Great Hall, instead of being in the forest with Grawp.
 * Harry does not appear to be furious about Snape's appointment as Defence Against the Dark Arts teacher, nor are any D.A.D.A. classes shown throughout the film.

9. The Half-Blood Prince

 * Discussion about choosing subjects and questioning of Prof. McGonagall were also not included in the movie. Simply Professor McGonagall is seen in the corridor giving class schedules to students and then chastising Harry and Ron for laughing at the newer students. She then instructs Harry to take Potions lesson and to bring Ron with him.
 * In the movie, when Harry and Ron entered the Potions class, they are both late, but Slughorn does not seem to have started the lessons yet. The two informed Prof. Slughorn that they do not have the required book, so Slughorn instructs them to get a book from the cabinet inside the room. When they see that there is only one new book left, they both grab for the new version of the book, titled Advanced Potion-Making. Ron successfully got the new book while Harry is left with the older copy, formerly property of the Half-Blood Prince. In the book both Ron and Harry get an old copy, with Ron's even having what he described as looking like a vomit stain.
 * In the book, Harry, Ron, and Hermione are the only Gryffindor students to take Slughorn's N.E.W.T. Potions class. In the film, many other students are present in Slughorn's class as well, including Dean Thomas, Seamus Finnigan, Neville Longbottom, Padma Patil, Lavender Brown, Romilda Vane, and Katie Bell, despite Romilda and Katie not even being in the same year as Harry and the others. In the film, Crabbe and Goyle are in the class as well, despite the book specifically stating that they were not. Pansy Parkinson also appears, although in the novel there was one unspecified Slytherin student in the class with Draco Malfoy, Blaise Zabini, and Theodore Nott.

10. The House of Gaunt

 * The Gaunt scene is cut. Yates stated, "In the books, the memories were a very big part of JK Rowling's story. We've actually pared them down in our story, and she was very supportive of that decision. They're such an enjoyable part of reading the Half-Blood Prince. But we've kind of distilled them down to two or three memories to try to keep everything more in the moment. Flashbacks in movies are tricky things; they tend to hold up the momentum of the story you're telling."
 * The movie only shows the memory in which Dumbledore goes to pick up Voldemort at the orphanage and the memory in which Voldemort asks Slughorn about the Horcruxes, which is shown twice, as in the book.
 * Harry doesn't get to know that the ring that Dumbledore has is actually a heirloom from the Peverell family.
 * The movie doesn't emphasise on the injury on Dumbledore's hand or Harry's insistence on asking him what caused it.
 * Dumbledore only refers to Merope Gaunt as "Voldemort's mother" when Harry asked about the ring. He tells Harry that the ring belonged to Voldemort's mother, when in the book it was retrieved in the hands of his uncle Morfin.
 * The Resurrection Stone mounted on the ring is cracked down the middle, right through the symbol of the Deathly Hallows. However, in the movie, the stone remains intact.

11. Hermione's Helping Hand

 * Instead of having each position try out separately (like in the book), Harry has all the positions play together, making it like an actual match without a seeker.
 * Hermione does use the Confundus Charm against Cormac McLaggen, however the spell is whispered into her hand in order to hide the incantation. Also, the incantation she uses is not the correct one. It is revealed in Harry Potter and the Deathly Hallows that the proper incantation is "Confundo". In the film, Hermione says "Confundus."

12. Silver and Opals

 * The scene where Harry, Hermione, and Ron meet Slughorn is moved from Honeydukes to the Three Broomsticks Inn. During the scene Slughorn mistakenly calls Ron "Wallenby". This is presumably a reference to Harry Potter and the Goblet of Fire where Mr. Crouch repeatedly calls Percy Weatherby.
 * In the movie, they see Ginny, Dean and Malfoy around them, but in the book they were never around.
 * For reasons unknown, in the film Hermione appears to act tipsy after the three leave the Three Broomsticks, though she sobers up immediately upon discovering Katie Bell.
 * Katie Bell is cursed by the necklace as in the book, and she is lifted into the air and silently screams with her head tilted back in a very frightening manner. As in the book, Hagrid comes and takes her to the castle, however Hagrid's role on the whole is very diminished.
 * Harry doesn’t meet Tonks and Mundungus Fletcher at Hogsmeade.
 * In the book, Leanne is crying when she tells McGonagall about what happened, but in the movie she is calm.

13. The Secret Riddle

 * The memory of the Wool's Orphanage doesn’t include talks of Tom Riddle hurting kids at the cave, which is essential to why he chose it as a Horcrux hiding place. Only a crude picture of the place is shown taped up on Riddle's bedroom wall.
 * In the novel, Dumbledore pours the memory into the Pensieve. In the film, he gives it to Harry to pour into the Pensieve.
 * In the novel, Dumbledore accompanies Harry into the various memories; in the film, Harry is alone.

14. Felix Felicis

 * In the film, at breakfast before the first Quidditch match, Luna Lovegood, not Hermione, notices Harry faking to slip Felix Felicis into Ron's drink.
 * The weather on the day of the first Quidditch match is snowing and stormy in the movie, whereas in the book it is clear, a circumstance which Ron attributes to the Felix Felicis he thinks he drank.
 * Zacharias Smith's Quidditch commentary is omitted.
 * Only a part of the match is shown. We see Ron save several goals, then we see Ginny score a goal. We see Ron save one more goal and the crowd starts chanting for him. Directly afterward, the scene changes to a party in the common room, and it is implied that Gryffindor won. We do not see Harry catch the Snitch and end the game (in fact, we only see Harry once during the match, and it is very brief. He is far away, hovering next to Ron when the Gryffindors start their offensive play).
 * Harper is apparently omitted.
 * There is no explanation as to why Malfoy isn't playing in the match, but we don't see the Slytherin seeker anyway, so we wouldn't know if Malfoy was playng or not.

15. The Unbreakable Vow

 * The discussion between Harry and Hermione inside the Hogwarts Library is included. Romilda Vane was introduced but she doesn't have dialogues. Madam Pince is not present in the movie.
 * Professor Trelawney is not present, Eldred Worple, Sanguini and other guests were not introduced by Prof. Slughorn but Filch's interruption holding Draco and telling everyone his gatecrashing is included.
 * There is much less conversation between Draco and Snape. Snape only mentions to Draco that he has made an Unbreakable Vow, then Draco emphasised that he doesn't need protection.
 * Harry overhears the conversation in the corridor while hiding but without the use of the Invisibility Cloak.

16. A Very Frosty Christmas



 * There has been an additional scene in the film which has no book equivalent. The Burrow is attacked by Death Eaters during the Christmas holidays. Bellatrix Lestrange and Fenrir Greyback are the only Death Eaters shown. Greyback flies and lands in a ball of flame and casts a ring of fire around the Burrow (possibly Fiendfyre, as the flames are quite large and take the form of a serpent). Lestrange lands in black smoke and taunts Harry, chanting "I killed Sirius Black! I killed Sirius Black!" Harry takes off after her in rage. Ginny takes off after him, trying to stop him. Lupin, Tonks, and Arthur Weasley follow them into the grassy marsh. While the five are lost in the field, looking for the Death Eaters, the Death Eaters take off and set the Burrow aflame, burning it presumably to the ground, before leaving. There is no further mention in the film of how the home is restored or what happened to it afterward. The Burrow was supposed to be protected against the Death Eaters, and they simply set fire to it with no effort. The destruction of the Burrow potentially could cause continuity issues for the film adaptation of The Deathly Hallows; it remains to be seen how the script works around it.




 * The discussion of Remus and Harry about Snape's character is shorter. Remus Lupin does not reveal to Harry that Snape helped him while he taught at Hogwarts as D.A.D.A. professor by brewing him a Wolfsbane Potion every month.
 * The movie omits the details that Fenrir Greyback is a werewolf, and also the part of Lupin mentioning that Greyback was the one who turned him into a werewolf.
 * No reason is shown for Tonks's lack of colour in her hair (it is brown, not pink). The book explains that it was because she was in love with Lupin and worried for his safety amidst the werewolves and also anxious, because he could not communicate with her.
 * In the movie, the part where Percy Weasley arrives at the Burrow on Christmas Day with the new Minister for Magic Rufus Scrimgeour is omitted, including the part where Scrimgeour attempts to persuade Harry to help the Ministry to tell to the Wizarding world that the Ministry's doing a wonderful job.
 * The part where the characters are listening to the music of Celestina Warbeck is omitted.
 * The Christmas season shown in the movie is a big contradiction on what the Chapter's title is. There are no signs of snow outside the Burrow and Ginny's nightdress seems unfit for a frosty season.
 * Also included in the Christmas celebrations at the Burrow are several scenes of suggested romance between Harry and Ginny. In the book, Ginny did not show clear signs of affection toward Harry until after they started going out.
 * It is implied that Tonks and Remus are already going out, as she seems to know Remus's transformation habits and calls him, "sweetheart". The Burrow sequence is their only appearance in the film; the only aspect of Tonks' personality changes from the book in evidence is that she appears to be more subdued than her previous appearance.

17. A Sluggish Memory

 * The memory of the Gaunt House, Merope with the locket, Voldemort going to kill the Riddles and stealing the ring, the memory of Voldemort working at Borgin and Burkes and wanting the cup and locket, and the one when Voldemort returns to the school to ask to teach have all been omitted. Only the memory of the orphanage and of Voldemort asking about Horcruxes were kept.
 * There's no mention of Tom killing the Riddle family.
 * Slughorn's false memory does not show cloudiness; instead, when Riddle asks about Horcruxes his voice becomes muted and Slughorn rebukes him angrily. Also, significantly, the word "horcrux" is not heard; in the book it is heard in the altered memory, though oddly Dumbedore appears to be unaware of its meaning.

18. Birthday Surprises

 * There are no Apparition lessons or examination taught by Wilkie Twycross.
 * In the book, Ron and Lavender break up due to Lavender seeing Ron and Hermione coming down from the boys' dormitory (not seeing Harry due to him hiding under his invisibility cloak) and assumes they were together.

19. Elf Tails

 * The Quidditch scene and Luna's Quidditch commentary from this chapter have been cut.
 * The film doesn't show Harry being admitted to the hospital wing, due to the absence of the Quidditch match.
 * No appearance nor mention of Dobby working in the Kitchen at the Castle, nor of Dobby and Kreacher tracking Draco for Harry.
 * In the film, Ron mutters Hermione's name while unconscious at the hospital wing with Harry, Hermione, Lavender, Ginny, Dumbledore, McGonagall, Pomfrey, Slughorn, and Snape present, and Lavender runs off in tears. This is how Ron and Lavender break up in the film.
 * The visiting of Hagrid, Fred, George, Arthur & Molly Weasley for Ron while in the Hospital wing were not shown in the movie. The praising to what Harry's did using a bezoar as a antidote to the poison is not mentioned by Fred but instead by Prof. Dumbledore.

20. Lord Voldemort's Request

 * The memory showing Hepzibah Smith and House-elf Hokey were not shown nor mentioned in the movie, and Voldemort applying for the D.A.D.A position is also omitted. Dumbledore also does not scold Harry about his inability to obtain the unaltered memory from Slughorn.
 * Prof. Dumbledore didn't mention to Harry that this position is possibly cursed by Voldemort because he refused Voldemort's request, in that no one can retain the position for more than one year.

21. The Unknowable Room

 * There is no mention of Crabbe and Goyle using Polyjuice Potion and standing guard for Malfoy outside of the Room of Requirement.
 * Draco is seen testing an apple on the vanishing cabinet. It comes back with a bite taken out. He then tests a white songbird in the cabinet, and it comes back dead. Draco's desperation and fear in this scene is palpable. It is likely that he was repeatedly testing to see if it would work correctly, and became more frightened the more the tests failed, as everything he sent through except for the black songbird came back damaged in some way. It is also possible that the white and black songbirds and their respective failure and success may be an act of symbolism or foreshadowing.
 * Tonks doesn't appear inside Hogwarts looking for Prof. Dumbledore.

22. After the Burial

 * The trio didn't receive a letter from Hagrid informing them that Aragog was dead. Instead Harry simply mentioned that he wants to go to Hagrid's place after drinking the Felix Felicis.
 * Instead of taking a few drops of the Felix Felicis, Harry drains the entire bottle.
 * Slughorn is seen stealing tentacula leaves, rather than working WITH Professor Sprout to obtain potions ingredients.
 * Aragog's size appears smaller than described and shown in both the books and the Chamber of Secrets (film).
 * Slughorn also asks Hagrid for the venom directly rather than sneaking a couple bottles.
 * Harry doesn't talk about his mum and dad's death to Slughorn to the extent that he does in the book.
 * In the film, Slughorn talks about a present that Harry's mother, Lily Evans once gave him. The present was a bowl with a few inches of clear water. There was a petal ,floating on the surface, which gradually sank and turned into a fish just as it reached the bottom. The fish was named Francis. Slughorn discovered that the fiish disappeared the day Lily Evans died. In the book, however, there is no mention of the present; Harry brings up the topic of his parents' death after Hagrid mentions them just before falling asleep.

23. Horcruxes

 * Only the ring and diary are mentioned to be horcruxes. The ring, which is supposed to be set with a plain round stone bearing a crude carving of the Deathly Hallows, is instead set with a fluorite-cut, honey-brown gemstone.
 * Dumbledore does not actually have possession of Tom Riddle's Diary as it is shown in the film; Harry gave it back to Lucius at the end of Chamber of Secrets. (However, Lucius gave the diary to Dobby, and Dobby may have given the diary to Harry or Dumbledore back).


 * As noted, the cup and locket story is left out, and something of Gryffindor or Ravenclaw and Nagini are not debated to be horcruxes. However, cases of swords are seen to be mounted to the balcony wall in Dumbledore's study.
 * Dumbledore only mentions that the horcruxes could be anything, thus it implies that they don't know what they could be, Dumbledore never mentions that Voldemort searched for treasures and that it might be possible that his horcruxes were Valuable treasures of Hogwarts founders. Harry never gets to know how Dumbledore found out about the cave.


 * Dumbledore and Harry do not have many talks about Voldemort like they did in the book. Voldemort is not explained as someone who likes to control people, who is very charming with all the teachers, who places great meaning on places where he has tortured others, and who feels a deep connection to Hogwarts because it is proof he is special and is a wizard and because it feels like his home. However, these details were focused on in the Prisoner of Azkaban movie.

24. Sectumsempra
"I know what you did, Malfoy. You hexed her, didn't you?"
 * The duel between Harry and Draco at the bathroom took place just after Harry questioning Katie Bell in the Great Hall regarding the cursed opal necklace. Katie looks at Draco then suddenly Harry chases him. In the book, the questioning of Harry on Katie Bell and Harry's duel with Draco took place between a couple of days and did not happen in the same day. In the book, Harry was tailing Draco using the Marauder's Map until he saw Draco inside the Boy's bathroom on the sixth floor. He overheard Draco crying and saw that he was accompanied by Moaning Myrtle.
 * In the film, Malfoy is running away from Harry and goes into a bathroom on the seventh floor, near the Room of Requirement. In the book, the bathroom that the duel takes place in is not on the seventh floor.
 * In the movie, Moaning Myrtle is not included.
 * Harry and Draco briefly duel before Harry uses the Sectumsempra spell and Snape's countercurse Vulnera Sanentur is an incantation rather than a song.
 * The duel is longer and more intense in the film. In the book, Malfoy turns around and attacks, and Harry almost immediately uses sectumsempra after the two of them cast about two spells each at each other. In the film, Harry and Malfoy shoot several spells at each other, hide behind stalls and shoot spells at each other underneath the stalls, run around the stalls while shooting spells at each other and finally Harry uses Sectumsempra on Draco when he sees him standing on the other side of the bathroom, directly after coming out from under cover.
 * In addition, the duel is composed of simple non-verbal dueling spells. Draco is not heard trying to use the Cruciatus Curse.
 * Directly before Malfoy attacks Harry, Harry talks to him, saying
 * The scene where Severus Snape gives Harry detention for the Sectumsempra spell/ownership of his textbook is cut and apparently never took place. This creates a plot hole in the film as Harry apparently gets away with using a potentially deadly spell against a classmate with no apparent punishment (this could also be seen as telegraphing the revelation that Snape is the Half-Blood Prince).
 * Ginny, not Harry, hides the textbook in the Room of Requirement. This will prove complicated in the final movie when Harry knows where to find the diadem horcrux based on where he hid the book (although Ginny is present during the final battle, so she could assist him).
 * In the same scene, Ginny kisses Harry and they both keep it secret. In the book, however, they kiss in full public view after the quidditch match between Gryffindor and Ravenclaw (during which, Harry was in Snape's detention); in the film a scene with Ron and Lavender kissing under identical circumstances appears instead. Also, they find a second songbird Draco tested on the cabinet, a black one, alive and singing, but they do not know its significance. The cabinet is covered by a tapestry and they do not see what it is.

25. The Seer Overheard

 * Emma Thompson does not return as Professor Trelawney and the scene where Snape's role as double-agent is not shown or mentioned.


 * The movie doesn't show Harry questioning Dumbledore as to why he trusted Snape.
 * In the book, Dumbledore and Harry (who was under the invisibility cloak) walk till the Hog's Head in the village of Hogsmead, from where they Disapparate to the cave. In the movie, they Disapparate from the Astronomy Tower in Hogwarts. Although often cited as a continuity break with the other films and the novels (which establish that one cannot apparate from within Hogwarts' grounds), in fact the Half-Blood Prince novel establishes that Dumbledore is able to remove the enchantment preventing this from certain locations, specifically (in the book) the room where apparating lessons are held; this is also supported by Dumbledore's comment in the film about having certain privileges as headmaster.

26. The Cave

 * In the book, Harry and Dumbledore have to swim from the rock they arrive on to the cave entrance; this is not shown.
 * The boat that has been used by Prof. Dumbledore and Harry to go to the island in the lake is not so small as described in the book. The potion was black rather than glowing green. The Goblet to be use to drink the potion in the basin was replaced into a shell. Dumbledore just saw it beside the basin rather than summon it using a non-verbal spell.
 * In the book, Dumbledore drinks about three cups of the potion before falling prey to its effects. In the film, he only drinks one.
 * Dumbledore drank all the liquid in the basin (Harry fed most of it to him) and suffered terrible pain while doing so. The spell Lumos Maxima is shown again, this time as a glowing ball of light that could be thrown rather than a more powerful version of Lumos. When Dumbledore asked for water, Harry refilled the basin using the Aguamenti spell, but the drinking shell could not hold the water. Then Harry tried to get water from the lake, but an Inferius appeared and grasped his hand, pulling him under water. Dumbledore used a great wave of fire to get rid of the Inferi and then successfully escaped with Harry after casting a spell that was only mentioned in the movie.
 * The locket in the movie was just made out of what appeared to be gold. It had no 'S' or emeralds on it, which was the way it was described in the book. However, they might make the real one look the way it was described in the book so that there will be a significant difference between the two.
 * In the book, Dumbledore is left in a considerably weakened state after drinking the potion, which continues up to his death. This is less evident in the film.

27. The Lightning Struck Tower

 * Madam Rosmerta is cut from the film. Instead, Draco states he gave the necklace to Katie Bell, and also shows Dumbledore a the dark mark on his arm. Harry and Dumbledore Apparate directly to the Astronomy Tower, rather than riding broomsticks. Harry is not frozen by Dumbledore and is on the floor below the top of the astronomy tower looking up through floorboards at the events, and is seen by Snape on his way to Dumbledore. In the film Snape signals to Harry to remain quiet.
 * Bellatrix Lestrange joins the Death Eaters at Hogwarts.
 * The scenes in which the moniker "Half-Blood Prince" are explained in detail are whittled down to a single line in which Snape states "I am the Half-Blood Prince," and walks off into the night. The meaning behind the title of the book and movie is cut. It isn't found out why Snape was the Half-Blood Prince (He is half-blood and his mother's maiden name was Prince)
 * Snape's argument with Dumbledore, which took place at the Forbidden Forest at night and is overheard by Hagrid, who disclosed to Harry in the book, is changed to taking taking place at the Astronomy Tower during the day, Harry arrives to overhear part of it and Snape leaves upon seeing Harry. This may be problematic to Deathly Hallows film, in Snape's memories, since in the book, after Snape talked with Dumbledore, he told him about Harry being a Horcrux. If this conversation is indeed the one in the Astronomy Tower, it is unknown then how Snape would know about this.
 * In the film, Draco shows Dumbledore that he has been branded with the Dark Mark, whereas in the book this is only an assumption by Harry, with no solid proof.
 * In the novel, it is said that Dumbledore appeared frozen in the sky. In the film Dumbledore immediately falls over the railing and down towards the ground.
 * In the novel, it says that a bright green light hit Dumbledore (Avada Kedavra), while in the movie, its more of a Cyan color.

28. Flight of the Prince

 * The ensuing battle between Hogwarts staff and students against Death Eaters has been significantly reduced to a rampage through Hogwarts; Bellatrix Lestrange busts out windows in the Great Hall. Snape jinxes one auror out of the way outside of the Great Hall.
 * The Battle of the Astronomy Tower was omitted from the film, along with the scene where Bill Weasley is bitten by Fenrir Greyback. The castle appears to be deserted except for one auror on duty, who Snape jinxes out of the way.
 * Furthermore, the role of Bellatrix Lestrange has been greatly expanded in the film. In the book, she does not fight in the Battle of the Astronomy Tower or witness Dumbledore's Death. Upon witnessing it in the film, she reacts by destroying everything with sadistic glee and delight.
 * In the film, Dracos' reluctance to go with the Death Eaters is much more obvious.
 * In the book, Snape reacts with livid emotion when Harry calls him a coward. However in the film, although Harry hurls this same insult at Snape, he does not react.
 * The only Death Eaters who even acknowledge Harrys' presence once he catches up to them at Hagrids Hut are Snape, Bellatrix, and Draco. The other Death Eaters, including Fenrir Greyback, continue to walk towards the gates and act as though Harry isn't there. Malfoy soon runs after them, and Bellatrix is soon to follow him. In the book, Fenrir attacks Harry and the other Death Eaters try to jinx him.

29. The Phoenix Lament

 * Rubeus Hagrid's hut is set on fire by Bellatrix Lestrange intentionally instead by Thorfinn Rowle due to the wand battle. The film doesn't show if Fang was trapped inside the hut and also Hagrid is not present in this scene. Harry and Hagrid didn't put out the fire using the Aguamenti spell.
 * Professor McGonagall joins the crowd who discovered Albus Dumbledore's body in the foot of the Astronomy Tower. She leads the Hogwarts students and staff in raising their wands to be rid of the Dark Mark and in respect for the now-deceased Headmaster.
 * There was also no debate or meeting at Headmaster's office between professors to discuss whether or not Dumbledore would be buried on Hogwarts grounds.

30. The White Tomb

 * The entire funeral scene is cut, and the last scene is the trio watching Fawkes flying away through the blue sky. In this scene Hermione mentions to Harry that Ron was not concerned with his interest in Ginny.
 * It is inferred that Ginny and Harry's relationship is still going strong, although in the book they split up on Harry's insistence that it's not safe for her to be close to him.
 * In the film, Harry finds Dumbledore's wand in his office after the Headmaster's death. This may be a significant aberration from the book where the wand is entombed with Dumbledore's body, although this scene may take place before the burial.

Mistakes

 * The use of the Millennium Bridge creates an anachronism if the film is supposed to take place in 1996-97 as did the book, as the bridge wasn't built until 2000.
 * There are several other anachronisms involving architecture. The scene at the start of the film shows Muggles working inside City Hall, a Norman Foster-designed building beside the Thames. This building was not complete until 2002. 30 St Mary Axe, the building commonly referred to as "The Gherkin", can be seen in the shot looking out of the City Hall windows, however this building wasn't completed until 2003. This error also pops up on the promotional poster, where the building is shown. Several other buildings also appear that were not around at the time.
 * When Harry first opened the Half-Blood Prince's Potions book, The phrase "This book is the property of The Half Blood Prince" was on the first page of the left-hand side of the book. But when Ginny took the book from Harry and opened it, she opened it from the right-hand side, yet she could read the same phrase. (There is also the possibility that the writing was on both sides of the book.)
 * Katie Bell is in Horace Slughorn's Potions class with Harry and his friends, even though she is a year above them. Romilda Vane is also present in these classes, despite being a fourth year.
 * Dumbledore keeps Tom Riddle's Diary in his desk in his office, even though Harry took it with him in the second film to free Dobby, although it is possible that Dumbledore retrieved it after Dobby's liberation.
 * The pictures in The Daily Prophet that Harry is reading in the cafe at the beginning of the movie has no moving pictures.
 * When Harry is dueling Malfoy during the Sectumsempra scene, he is using nonverbal spells, something he is supposed to be bad at with the exception of Levicorpus.

Awards

 * Harry Potter and the Half-Blood Prince won the 2007 Movies.com award for film you "Can't Wait For."
 * Harry Potter and the Half-Blood Prince was nominated for the 2010 Academy Award for Best Achievement in Cinematography.
