Behind the Scenes

 * In film adaptation of Harry Potter and the Half-Blood Prince, a different set was used to portray this classroom. But in the video game adaption it resumes its layout from the the first and second film and the fifth video game.
 * When Minerva McGonagall taught the students to dance in the film adaptation of Harry Potter and the Goblet of Fire, the room used to portray the classroom was the one used to portray the hospital wing in the film adaptation of Harry Potter and the Philosopher's Stone
