Harry Potter and the Sorcerer's Stone (film)

The film version of Harry Potter and the Philosopher's Stone was the first film adaptation in the Harry Potter series. It starred Daniel Radcliffe as Harry Potter, Rupert Grint as Ron Weasley, and Emma Watson as Hermione Granger, and was directed by Chris Columbus. There are only three actors in the film who are American, Zoë Wanamaker (Rolanda Hooch), who had been acting in Great Britain for quite a while, Verne Troyer (Griphook), who was voiced by the British Warwick Davis, and Eleanor Columbus (Susan Bones), who had no lines.

For American release, just as was done with the book, the studio retitled the film Harry Potter and the Sorcerer's Stone.

Differences between novel and film

 * Vernon Dursley's day at Grunnings and his encounter with the wizards during his lunch break the day before Harry's arrival at Privet Drive are omitted from the film.
 * Vernon Dursley noticed Professor McGonagall in her Animagus form earlier in the day, thinking she was reading a map. This was omitted as well.
 * At the start of the novel, Professor McGonagall in her animagus form had been observing Vernon Dursley prior to her meeting with Dumbledore and Hagrid. While this scene was omitted from the film, it was referenced when McGonagall voiced her objections in leaving Harry in the Dursley's care when she said she had, "watched them all day"
 * In the book, the Dursleys and Harry are accompanied to the zoo by Dudley's friend Piers Polkiss. He is omitted in the film as are the attempts of the Dursleys to have Harry stay with Arabella Figg.
 * In the book the glass of the snake tank remains vanished. In the film it comes back on, trapping Dudley in the tank.
 * The scene when Harry gets Dudley's second bedroom is omitted. This causes a continuity error in the next films where Harry already has this bedroom, although the room could have been given to him when he returned to Privet Drive.
 * Harry states in the second movie that the snake at the zoo was a python. The snake at the zoo is said to be from Burma. In the novel, it is a boa constrictor from Brazil, not a python from Burma. However, both the novel and the film reveal the snake was bred in captivity.
 * In the book, the snake addressed Harry as "amigo" when thanking him for freeing it - presumably, a nod by JK Rowling to its South American ancestry. In the film, the snake simply says "thanks."
 * In the book, Vernon Dursley warns Dudley not to receive or eat anything that Hagrid gives him when he was making sausages for Harry. In the film, Vernon doesn't mention this to Dudley, as Dudley is later seen eating some of Harry's birthday cake.
 * Hagrid tells Harry about the death of his parents on the island in the sea. However in the film, Harry asks about this at the Leaky Cauldron.
 * In the novel, when Harry buys his wand, Hagrid is with him. But in the movie, Hagrid is not present, having gone to buy Hedwig. Also, in the novel Harry is with Hagrid when he buys Hedwig, before going to Ollivander's Wand Shop.
 * In the book, Harry names Hedwig from a History of Magic book
 * In the book Harry first met Draco Malfoy in Diagon Alley while shopping and later learned who he was on the Hogwarts Express, where Harry chose not to befriend him after Draco insulted Ron Weasley. In the film, both these events occur at Hogwarts before the Sorting.
 * After his first visit to Diagon Alley, Harry returns to live with the Dursleys for several weeks and Vernon Dursley drives him to the train station. In the film it's made to appear as if Harry went directly to Hogwarts after buying his supplies.
 * The character Peeves is omitted, although a scene was filmed for him, but ended up being cut, even being omitted from the current DVD release. Peeves has yet to appear in any of the films.
 * In the book Harry first learns about the connection between Dumbledore and Flamel on the back of his chocolate frogs card. In the movie, it is Hermione who comes across the name in a book she picked up for 'light reading'. In a deleted scene however you see Harry finding the name on a chocolate frog card after which the trio rans of to the library, so it only appears as a "mistake".
 * Sorting was done alphabetically in the novel, and out of order in the film. Also, only Hermione, Malfoy, Susan Bones, Ron and Harry are sorted in the film.
 * In the novel, after the sorting, Dumbledore stands to say a few words and comically utters a few random words at which point supper begins. This is omitted in the film, with Dumbledore giving the start of term notices instead.
 * Harry learns that only Slytherins go bad from Hagrid in Diagon Alley. In the film, he learns it from Ron during the Sorting ceremony.
 * Hedwig's name is never mentioned. The same goes for Mrs. Norris.
 * In the novel, Oliver Wood meets Harry after coming out of a Charms class. However, in the movie, Wood comes out of a Defence Against the Dark Arts lesson.
 * The scene where Malfoy challenged Harry to a duel, but had actually tricked him by tipping off Filch was omitted. Instead, Harry, Ron and Hermione accidentally go to the Forbidden Corridor.
 * In the film, Harry, Ron and Hermione see Fluffy in the Forbidden Corridor after their escape from Filch and Mrs. Norris. In the book, Neville was also with them.
 * In the book Percy Weasley wears glasses but throughout the movie, he is seen without them.
 * In the novel, Harry sees his parents and his grandparents in the Mirror of Erised, but this was changed in the movie to where Harry just sees his parents.
 * In the book, Nicolas Flamel's name is spelled Nicolas. In the film, an "H" is added spelling it "Nicholas Flamel".
 * The Hufflepuff-Gryffindor Quidditch match, where Snape is the referee, is omitted in the film. Instead, Harry hears Snape talking to Quirrell when he is walking to the Mirror of Erised.
 * When Harry and Hermione get detention, it is because they left the Invisibility Cloak in the Astronomy tower while sending Norbert to Charlie Weasley. In the film, they get detention because Draco Malfoy saw them in Hagrid's hut past curfew. Ron is also with them in the film while in the book he was recovering in the hosptial wing after being bitten by Norbert. Also in the film Ron gets detention instead of Neville.
 * On the way to the Philosopher's Stone, each obstacle was created by a teacher. While probably the same case in the film, this wasn't directly acknowledged. Also, in the film Quirrel's and Snape's rooms are omitted, although they are present in the video game. Because of this omission, Hermione stays with Ron after Ron was injured in the chess match at McGonagall's room instead of traveling with Harry as far as the Potions room before heading back.
 * In the movie, when Harry, Ron, and Hermione fall into the Devil's Snare, Hermione and Harry escape by relaxing, and Hermione saves Ron with Lumos Solem. But in the novel, there is no "relaxing" part, and Hermione saves both Harry and Ron with bluebell flames.
 * Likewise, in the novel it is Hermione who panics during the incident with the Devil's Snare and Ron who has to snap her out of it. In the film, this is reversed - Ron panics and Hermione calms Ron down.
 * In the novel, Harry, Hermione and Ron, each seized a broomstick and kicked off into the air to chase the Winged Keys, while in the film, only Harry flew with a broomstick. The same is for the PC game.
 * In the book, Harry Potter is unconscious when Quirinus Quirrell dies, while in the film, Harry watches Quirrell die. This creates a continuity error with his ability to a see a Thestral in the film version of Harry Potter and the Order of the Phoenix, since Harry could not see Thestrals until he saw Cedric Diggory die.
 * In the book, when Harry touched Quirrell, Quirrell's skin blistered wherever Harry touched. In the fim, when Harry touched him, the bad guy turned to stone and crumbled. Also, when Harry grabbed his face, it made the whole body demolish and Voldemort escaped. This is what knocked Harry out.

Character physical appearance
Some notable differences exist between key cast members of the film, compared to the way their characters are described in the books:
 * Hermione is described as having bushy hair and prominent front teeth, while actress Emma Watson has normal sized teeth and her hair, though bushy in this film, isn't as bad as described in the book (and later films do away with bushy hairstyles altogether).
 * Harry has green eyes, but actor Daniel Radcliffe was unable to wear contact lenses, due to an allergic reaction (except in one scene - see below).
 * Ron is described as tall and lanky, while Fred and George are shorter. Actor Rupert Grint is not tall and lanky in this initial film, while two tall actors were cast for Fred and George.

The Blu-Ray edition of Philosopher's Stone includes commentary from director Chris Columbus that reveals that the final scene of the film -- where Harry, Hermione and Ron depart on Hogwarts Express -- was the first scene shot. As such, some changes in Harry and Hermione's physical appearance can be seen. Emma Watson was initially fitted with prosthetic teeth to make her look more like the book version of Hermione, but this was abandoned as impractical after the first scene was shot. Columbus says editing made the buck teeth less obvious, but they are still visible during a brief bit of dialogue. Actor Radcliffe, meanwhile, was fitted with green contact lenses which are clearly visible in close-ups, but they weren't used after this first day of shooting because they irritated Radcliffe's eyes.

Differences Between Philosopher's Stone and Sorcerer's Stone Films

 * Five different takes were necessary to replace the words Philosopher's Stone with Sorcerer's Stone in the American version of the film. When the two DVDs were compared side by side it was noticed that in every case but one, only a slight difference in synchronization was noticed. The most noticeable difference was when Hermione was reading from the book she had taken out of the library for a "bit of light reading". The words on the page were changed from Philosopher's to Sorcerer's and her fingers, while straight in Philosopher's (her fingernails can be seen) they are bent in Sorcerer's (her fingernails cannot be seen).
 * The Ultimate Edition DVD/Blu-Ray uses the Philosopher's Stone version of the film, although behind-the-scenes footage in the accompanying Creating the World of Harry Potter documentary shows the actors performing scenes with the Sorcerer's Stone dialogue.

Mistakes

 * When Ron falls off the Horse during the massive chess game, he hits the floor. You can clearly see that it is a stunt double, and not Rupert Grint. It is easier to see if you pause it when he hits the floor the first time, and bounces.
 * When Harry, Ron and Hermione rush to Hagrid after the end of the year exams, and Harry is saying something that ends with, "Why didn't I see it before?" Hermione is mouthing part of that line.
 * At the start of term feast, after Harry is sorted into Gryffindor, he sits down on the right side of the table next to Ron. When the feast appears, Harry is on the other side of the table, next to Hermione.
 * When the three children get past Fluffy because the harp is playing, as Fluffy wakes he dribbles on Ron's shoulder. However, when they fall down into the Devil's Snare, his shirt is completely dry.
 * During the flying lesson scene, some strands of Hermione's hair have very deep crimps on both sides of her face in a few shots. In other shots the crimps are far looser and still in additional shots, there are no crimps whatsoever.
 * When Harry receives his first letter in the mail, Dudley snatches it from him before he has a chance to open it. Then he gives it to his father (Uncle Vernon), and Uncle Vernon says "Who'd be writing to you?" If you watch Dudley carefully, you can see him mouth what Uncle Vernon is saying.
 * In the scene where Hermione, Ron and Harry are returning to Gryffindor's tower room after being in the third floor room for the first time, you are able to see the feet of one of the crew. It happens just as they are passing through the picture hole, where Harry turns a couple of times to check that the "door" is closing. And it is in fact, because someone is walking behind it and pushing it shut, since the picture hangs several inches off the floor.
 * At the Quidditch match, after Hermione sets Snape's cloak on fire and someone shouts, "Fire! You're on fire!" there is a close-up of Harry with his hands gripping the Nimbus 2000. In this shot, the wire rods which are attached/taped to the broomstick, near Harry's fingers, that lead under both of his red sleeves, are entirely visible.
 * After falling from the Devil's Snare, Harry tells Ron, "Lucky Hermione pays attention in Herbology." Then as Ron starts to walk toward Harry, there is a crew member's arm and hand gripping the back of Ron's shirt at the bottom.
 * Petunia has her hands on Dudley's eyes as they walk towards all of his birthday gifts. When she removes her hands from Dudley's eyes, in this shot and in the next, the long black microphone wire as well as its tape, which obviously peeled free, are blatantly visible and are sticking out at the neckline of her v-neck top under the pearl necklace. It's gone in the following shots.
 * During the Quidditch match Harry's broomstick tries to shake him off, due to the spell. After Hermione tells Ron, "Leave it to me", in Harry's last close-up before he flips over, the seat that is attached to the broomstick, to make it more comfortable for Dan Radcliffe to sit on, is entirely visible. Glimpses of other seats can be had during the match as well.
 * Being chased by the flying keys, as Harry zips by on the broomstick he tosses the key, Hermione catches it and runs to the door. In the next shot, a close-up, as she tries to unlock the door, an electrical cable hangs down beside the column, that was not in the previous shots. There is also an electrical cable coming out from under the back of Hermione's jumper that is blatantly visible as well.
 * When the troll enters the girls' lavatory, in the wide shot as Hermione walks backwards towards the cubicles, the room becomes brighter from the storm. With this extra bright light it is simple to see that the wall between the second and third cubicles actually touches the floor, unlike the other cubicle walls. Yet, in the overhead shot as the troll's club slams into the cubicles, Hermione is lying under that very wall crawling away.
 * When the troll is about to swing at Harry for the third time with his club, Ron levitates his club in mid-air. When the club falls, it hits the trolls head with a loud thunk, then falls to the ground. But you never hear any sound of the club hitting the ground.
 * While at the zoo, after Dudley falls into the snake exhibit there is a close-up of the Python's head. At the start of this shot, before Dudley pops out of the water, in the upper left corner of the screen a wood stick comes down to actually prod the trained snake and then quickly moves back up out of shot.
 * During the scene with the "flying" letters Harry gets one letter and tries to go in his "room", but Uncle Vernon grabs him. When Harry says, "They're my letters," if you watch closely his lips don't move.
 * During the Quidditch match as the players ride their broomsticks, visible in quite a few shots are the two wires that are attached to the broom handle, between their legs, that extend down with a clamped loop that goes around their feet. In some shots the wires between their legs are edited, but the wire loops around their feet are perfectly visible, like in the following example. When the Slytherin score hits 10 onscreen, in the next shot, as Flint shouts, "Take that side," the wire is completely visible at his right foot under his cloak. Two examples where the entire wires are visible are, when Flint grabs the club and says, "Gimme that!" the wires are blatantly visible and he then proceeds to slam the Bludger into Wood, who falls. Next close-up of one of the twins, the wires are clearly visible before Flint starts to leap over him.
 * When Hagrid steps off the motorbike while holding young Harry, the Dursley's house (with a small bush to the right of the front door) is visible directly behind McGonagall. The house is fully attached on both sides to homes with a one car garage. Yet after Vernon asks, "Who'd be writing to you?" in the shot of the owl dropping the letter which flies through the front door mail slot, the house to the left of the Dursleys' (when facing the front) has a two car garage, is not attached to the Dursley's house and is quite a bit away from the Dursleys' house as well. Then in Chamber of Secrets, the house to the right (when facing the back) is attached once again in the same manner as at the start of this film with young Harry.
 * After Quirrell announces there's a troll in the dungeon, Dumbledore shouts, "Silence!" and soon continues, "Teachers will follow me to the dungeons." In the following shot of McGonagall, the wires that the candles hang from are plainly visible.
 * Hermione opens the door to Fluffy's room when she says, "Alohomora!" so she, Harry and Ron could hide from Filch and Mrs. Norris. As Ron closes the door the top of the third floor corridor set is visible at the top of the screen.
 * At the snake exhibit, while Harry speaks with the Python the snake's body lies curled over a long wood log and a large rock. In the shot from outside the Python's exhibit, after the glass pane disappears Dudley falls over the rail and the snake is gone, not positioned differently, but altogether gone! In the next overhead shot inside the Python's exhibit, while Dudley falls the snake is back lying on the log and rock, in the same position as in the previous shots.
 * Petunia and Dudley enter the house when they return from the zoo, followed by Vernon and Harry. The crew's equipment is plainly visible on the ground beyond the doorway. Also, the pavement at the threshold extends far beyond the doorway and just before Vernon walks into the house, Vernon is visibly coming from the side of the doorway. In the earlier exterior shot when they stand by the car before they leave, as Vernon says, "I'm warning you now boy...," not only is the ground at the doorway completely different, there is a garden surrounded by white bricks beside the door, making it impossible for Vernon to have been standing there.
 * Near the start, Percy says "Boys upstairs and down on your left, girls the same on your right". However, after the three heroes have been to investigate Fluffy and they go back to the dorms, when they reach the top of the stairs Hermione goes to the left and the boys head right.
 * Harry, Ron, and Hermione, run to Hagrid's hut to tell him that they know about the Stone and they knock on the door. As Hagrid opens the door in the first shot looking out, Harry stands behind his tape mark and Hermione and Ron visibly stand behind their shared black tape mark on the step.
 * Dumbledore, McGonagall and Hagrid leave baby Harry on the Dursley's doorstep. When the shot opens in the first close-up of the baby, as Dumbledore places the envelope on the blanket, though a good portion of his forehead is visible, the scar is not there. In his next close-up, it is very apparent, due to the position of the scar, that part of it should have been visible on his forehead in the previous close-up.
 * After the Queen attacks the Knight's horse during the chess game, Ron goes flying back and falls. In the shot as he hits the ground, the black protective gear that he wears is visible when his grey T-shirt rolls up and the button on his left cuff is open, yet closed in the next close-up.
 * As Hermione hides under the sinks the troll smashes the front basin of the second sink on the right, leaving its faucets and surrounding sinks intact. Though in a view of the entire lavatory when the troll holds Harry upside down, from behind Hermione, the entire second sink, its faucets and trim are entirely missing and the entire fourth sink, which was never touched, is as well, both are gone. When the troll is knocked out, as Hermione stands up and moves toward Harry and Ron, though the faucets of the second sink are back, the front basin of the second sink is visibly broken again just as in the original shot, and the entire fourth sink is still inexplicably gone in this shot.
 * After escaping Devil's Snare, Harry, Ron and Hermione enter the Key room. When Ron says, "You're the youngest seeker in a century." In the next shot of Harry as he grips the broomstick, the wire that it hangs from is clearly visible at its bristles.
 * When the Queen attacks Ron's horse during the chess game, in the shot from behind Ron, as he falls the black straps attached to the horse's left rear leg, used to aid the stunt, is completely visible.
 * At the end of term feast, Dumbledore stands and says, "Another year gone." In the next shot of the Gryffindor table, part of the camera equipment is actually visible at the lower right corner of the screen.
 * In Hagrid's hut, Harry, Ron and Hermione gather round the table as Hagrid places the dragon egg in the centre. As the egg starts to hatch the shell flies everywhere and between Hermione and Hagrid camera equipment is visible at the lower left corner of the screen.
 * Just after Slytherin scores twenty points, Flint and his teammate surround Angelina. When one grabs the quaffle from Angelina, they fly past the second Gryffindor tower – we see the first Gryffindor tower, two staff towers (grey/black), Slytherin tower and the second Gryffindor tower behind them - then Angelina covers her head with her arm. However, in the next shot she actually crashes into the tower that she already flew past.
 * At the zoo, Harry looks to his right, at the 'bred in captivity' sign of the Python. In this close-up, the green plant that is below, to the side of the exhibit sign, is protruding out past where the glass supposedly is, yet this is BEFORE the glass disappears. As a matter of fact, this plant, nearest the exhibit sign, changes its position considerably throughout these shots.
 * When Harry, Ron and Hermione are running away from Mrs. Norris, Harry yells, "Quick hide through that door!" and if you look close enough you can see that his mouth doesn't move when he says that.
 * When Harry is in the potions class he is caught writing notes down, we see his neat writing in close up ... but when the camera angle changes we can see that the writing has changed in size to very large letters and quite messy writing.
 * Harry, Ron and Hermione are in Hagrid's hut and the egg inside the cauldron in the fireplace starts rattling. In the shot looking up at Hagrid from behind the cauldron, at the top left of the screen in front of the fireplace, as Hagrid retrieves the egg a piece of equipment comes down then quickly goes back up and at the top in the centre there is a small black film square that is not part of the fireplace.
 * As the troll begins to lift Harry with his huge club in the girls' lavatory, in the overhead shot as Harry hangs on to the edge of the 'real' club, at the bottom left of the screen the crew's blue equipment is perfectly visible.
 * When Harry is walking in the library's restricted section, you see the shadow of the library pillars on the bookshelf. If the light was coming from his lantern, there would be no shadow - the light is obviously from a spotlight elsewhere.
 * In the Key room after Hermione asks, "What's this all about?" Ron takes his wand out and starts for the door. In the wide shot facing the door as he and Hermione pass to Harry's left the bar attached to the underside of the broomstick bristles is visible. It is not visible in other shots.
 * When the first years are first led into the Great Hall, in the shot facing the teacher's table, the twins sit to Wood's left at the end of Gryffindor's table. However, in the next shot facing the first years, the twins sit on Wood's right.
 * When Harry and Hagrid are in Gringotts, Hagrid takes the letter from Professor Dumbleldore out of his pocket to give to the Head Goblin. The string it is tied with has a bow that runs from the top to bottom of the envelope, and the envelope is creased. When the Goblin takes it off Hagrid, it is a different envelope - the bow runs from left to right and the envelope is not creased. When viewed from where Harry and Hagrid are standing, the final shot of the envelope again shows it is creased.
 * In the scene at the beginning of the movie where all of the letters from Hogwarts are coming into the Dursley's house, it causes everything to shake. It is quite obvious, however, that it is just the cameras that are moving as no objects in the room are moving at all (ie. the curtains, or any of the knicknacks).
 * Harry gives Vernon two letters and he walks to the other end of the table to open the Hogwarts envelope. When Dudley grabs the letter, as he shouts, "Dad look! Harry's got a letter!" under Dudley's chair, to the left, the black tape mark is visible on the carpet covering. The carpet is covered over near Dudley's chair and on the other side of Vernon, near the black mat. In the close-up of the letter as Vernon holds it, the carpet is back to normal near Dudley's chair.
 * In the chess scene, at the end of the montage of shots of pieces being smashed, the White Queen turns her attention to a Black Castle. The first stroke of her sword clearly goes through the structure of the castle, which disintegrates. We cut to various different angles and watch pieces of the destroyed castle flying all over the place. Cut back to the original angle, and we see the Queen attacking again, but the Castle is completely intact - only the figure from on top of it is missing. And it cannot have been the second castle, since that's Hermione's position.
 * When Harry walks into Ollivander's, in the overhead shot of the shop the table is angled directly in front of the ladder. Yet, when Mr. Ollivander hands Harry the second wand the table is beside the ladder in this shot.
 * When Harry, Ron and Hermione are heading to Hagrid's hut, near the end of the movie, a group of three people behind them walk into another corridor. Then a second or two later the same group walks into the same corridor.
 * In the scene in Diagon alley when Harry first enters there are some witches on the left hand side of the screen looking at what appears to be large lollipops and Harry walks past them. The camera angle changes and Harry walks past them again.
 * After Dudley shouts, "Wake up, cousin! We're going to the zoo," he pushes Harry back into the cupboard and runs into the kitchen. When he opens the door, the kitchen floor is visible and there are no floor mats. Yet, once Harry walks into the kitchen there is a taped black mat on the floor at the door and another black mat at the counter, under the stools that were visible in the previous shot, when Petunia bangs on the cupboard door.
 * At the hut on the rock, after Harry draws the candles in the dirt, he glances behind him at Dudley's watch. In the next close-up of the watch, as it turns 12:00, the watch is actually on Dudley's wrist (notice his fingers) the opposite way from the previous shot.
 * In the Dursley's kitchen, as Harry walks by, on the table is Vernon's cereal bowl between the coffee pot on his right and OJ on his left, plus the tea pot is in the centre of the table. In the close-up as Vernon says, "Yours? Who'd be writing to you?" the cereal bowl is missing and the tea pot is near his OJ. In the next close-up of the letter, the cereal bowl is back and the OJ is now on Vernon's right, near the coffee cup.
 * On the Hogwarts Express, as Ron says, "This is Scabbers by the way," the acrylic string/wire which is attached to the bottom of Bertie Botts box, that is over Scabber's head, is perfectly visible.
 * In the shots facing Vernon, he holds the first Hogwarts letter while sitting at the table. Though in the close-up of the letter as he holds it, it is not Richard Griffiths' hand, that is shown with bitten up fingernails, holding the envelope.
 * When Hagrid enters the hut on the rock, as well as when he leaves, the bare floor near the front door is clearly visible. However, when he says, "It's not everyday your young man turns eleven, now is it?" in the next shot as Hagrid sits down, on the floor to his left is the crew's mat with marks for the Dursleys (Fiona Shaw and Richard Griffiths), who stand near the door.
 * The morning of Dudley's birthday, Petunia wakes Harry and the next shot shows Harry in the cupboard with the shelves behind him. When Dudley runs downstairs and pushes Harry back into the cupboard, things inside are positioned differently. This also occurs in the two shots when Harry plays with the small plastic figures inside the cupboard and then when he peeks out as Vernon attaches the wood to the mail slot.
 * In the opening shot at the hut on the rock, when the camera pans down to Harry lying on the floor the long marks that are taped to the floor near the couch are visible. These are the positions of Vernon and Petunia when confronting Hagrid about Hogwarts.
 * When Harry and Hagrid walk down Diagon Alley, in the close-up of Quality Quidditch Supplies, a clear reflection of a crew member in a blue shirt is visible, at the top of the screen in the hanging vertical pennant, just as the man with the long red hair walks past the camera.
 * In the scene when Harry talks to the snake, the camera shows a close up of the snake, and it blinks. Snakes don't blink, however the book also mentions the snake blinking.
 * When Harry and Hagrid walk into Diagon Alley, in the first shot, as they start down the street, on their right they immediately pass; 1- a man in black standing at the doorway to the Daily Prophet office, writing in a notebook, who then starts to walk away. 2- particular men and women walking past the store. 3- store window with Quidditch uniforms. 4- children looking in store window. A few shots later, they pass on their right a man, with bushy grey sideburns, walking with a woman dressed in black, yet in the next shot that same man and woman are chatting in the doorway to the Owl Emporium on their left. Then a few shots after that, still walking, Harry and Hagrid pass all the numbers, 1 through 4 again in close-up.
 * Harry speaks with Quirrell near the Mirror of Erised and the arrangement of the cloth in his turban differs in two shots than in the rest of the shots. First in the shot facing Harry as Quirrell says, "While everyone else was running about the dungeon, he went to the third floor to head me off," and then in the back shot just before Quirrell unwraps the turban, after Voldemort says, "I have strength enough for this."
 * As Hagrid aims his umbrella at Dudley while he eats Harry's birthday cake, in the side shot one end of the blue string (that was tied around the cake box) hangs down the side of the table, but when Vernon rushes Petunia and Dudley off, in this shot that end of the string lies on top of the table. Yet, when Hagrid says, "We're a bit behind schedule. Best be off," the string hangs off the side again.
 * When Harry lifts the mail from the floor at the Dursleys, the Hogwarts envelope flap is sealed shut and it has the red wax seal at the tip. Yet in the kitchen after he hands Vernon the other letters, Harry holds the Hogwarts envelope and though the red seal is on the back, the flap itself is not sealed shut. The wax seals differ in both shots as well.
 * After Voldemort's soul flies through Harry, he crashes down on the stairs and his hand sticks out over one of the steps. In the next shot of Harry lying there, his hand no longer lies over the step. Harry is knocked out and could not have moved.
 * After shopping in Diagon Alley, when Harry confronts Hagrid about Voldemort, in the first overhead wide shot Hedwig's cage is right next to Hagrid on the bench and is positioned a particular way. Yet in the next shot, the cage is much farther from Hagrid and is positioned the opposite way on the bench.
 * When Wood is telling Harry the rules of Quidditch he says that if you catch the Snitch the game is over, which is true but then he also says that which ever Seeker catches the Snitch, their team wins, but that isn't true. Granted that the 150 extra points probably would give you the winning lead, but as JKR pointed out in Harry Potter and the Goblet of Fire at the Quidditch World Cup, you can catch the Snitch but lose the match. This happens again in Harry Potter and the Order of the Phoenix in the Gryffindor vs. Hufflepuff Quidditch match.
 * As Hermione walks toward the troll, just before she asks, "Is it dead?" the long towel hanging from the rod beside the sinks is visibly straight. When Harry lifts his wand with troll booger/bogey, in the shot of him as he grimaces and groans, the towel on the rod is visible behind him and it's messy. Yet when McGonagall, Snape and Quirrell walk in, the long towel is straight again.
 * In the scene where Harry figures out that Hagrid got his dragon egg from "Snape"(Quirrell), at the beginning of the scene, Harry's cloak is buttoned and still is when he, Hermione, and Ron are running to Hagrid's hut. When he reaches Hagrid's hut, it is unbuttoned even though he never unbuttoned it himself.
 * At the end-of-the-year feast the Slytherin banner is green and gold, but their house colours are green and sliver, as evident by their robes.
 * When Madame Hooch leaves with Neville to go to the hospital wing, Seamus holds his broomstick with the bristles on the ground as Malfoy ridicules Neville. However, as Malfoy steps on his broomstick and then flies away, the bristles on Seamus' broomstick are now at the top. Then when Harry takes off on his broomstick, the bristles on Seamus' broom are on the ground once again.
 * After Seamus' disaster with the rum spell, the mail arrives. Ron catches his mail, then holds the Daily Prophet in his right hand and the letters in his left. Yet in the next close-up he holds the Daily Prophet in his left hand and the letters in his right.
 * When Dudley falls into the water in the Python's exhibit, his clothes are completely soaked. Yet when Dudley yells and bangs on the glass, in the shot facing Petunia as she screams, it is quite apparent that Dudley's jumper is not entirely wet. The wet hair at the back of his head lies flat in the second shot as well.
 * In the first-year's first ever flying lesson, Madam Hooch tells the students to rise off the ground after her whistle. She proceeds to countdown from three to one and then blow her whistle. Neville rises off the ground after the whistle has gone, which was what Madam Hooch told them to do, so Neville was not technically doing anything wrong. (In the book, Neville did take off before the whistle, though).
 * When Harry first unwraps the invisibility cloak, it is clearly visible, only to become invisible once Harry puts it on. Later in the film, after escaping the library and narrowly avoiding being caught by Snape, Harry enters the room with the Mirror of Erised and removes the cloak. It should now be visible, but we subsequently see Harry walking further into the room with nothing in his hands - surely he didn't just drop the cloak by the door.
 * A copy of the Daily Prophet shows the date as Friday, August 14, 2001. This is an anachronism as the film takes place in 1991 (in the original book the newspaper was published on Friday, September 6, 1991).
 * In the scene where Wood is showing Harry the Golden Snitch, as the Snitch lifts into the air towards the camera and Harry follows it with his eyes. Wood, however, looks around randomly and in the opposite direction of where the Snitch obviously went.
 * During the sorting ceremony, when Hermione is sorted into Gryffindor she leaves to the right (her left) but when Ron is sorted he leaves to the left (his right).
 * When Harry is reading the newspaper aloud about the break-in at Gringotts he mentions the vault number, but if you pause the film and read the newspaper it doesn't mention the vault number.
 * When Harry enters the room with the Mirror of Erised in it with Ron, they drop the cloak. You can clearly see the green cloth which has obviously been used to film, then edited.
 * The final scene of the film, the farewell at Hogwarts Station, was actually the first scene shot. As a result, Radcliffe appears noticeably younger than he does in earlier scenes in the film. As described in "Character physical appearance", above, this first scene also used later-abandoned make-up concepts for Harry and Hermione -- green contact lenses and prosthetic teeth, respectively -- not seen earlier in the film.
 * When Wood is showing Harry the Golden Snitch, he is not wearing gloves. This causes a continuity error with Harry Potter and the Deathly Hallows, as it means that (unless the Snitch used in the first Quidditch game is a different Snitch) the Snitch's flesh memory would not respond to Harry.
 * When Harry, Hermione and Ron are discussing Voldemort and Snape after the Forbidden Forest scene, Hermione actually says Voldemort's name, instead of You-Know-Who, wheras in the Order of The Phoenix, she seems to have finally been able to say Voldemort without flinching.
 * During the feast at the beginning of the movie, Percy tells Harry that Snape has been after Quirrell's job for years, but since Voldemort's jinx on the job only let a teacher keep the job for one year, this would have been impossible.
