Goofs for Harry Potter and the Sorcerer's Stone

• Crew or equipment visible: When Harry, Ron, and Hermione are struggling in the Devil's Snare, a puppeteer can be seen on the left of the screen, working at least some of the masses of tendrils.
• During the train journey, Ron's hair is parted in several different places.
• Harry's glasses sometimes have lenses, and sometimes don't, as do Dumbledore's.
• When Harry, Ron and Hermione are talking to Hagrid about Fluffy, Ron's scarf goes from being on his shoulder to being draped over his shoulder.
• Harry's scar clearly changes positions throughout the movie.
• The note that Hagrid gives to the teller in the bank is wrinkled in one shot, neat and clean in the next, and then back to wrinkled.
• Just after passing Madam Malkin's shop and before the owl emporium in Diagon Alley, a woman dressed all in black and a man with a burgandy top hat and mutton chops pass on Harry's right walking in the opposite direction. In the next shot, as Harry looks to his left, the same pair can be seen standing and chatting in the doorway of the owl emporium.
• When the first years climb the stairs and meet Professor McGonagall for the first time, Ron's robe is hanging partly open in one shot, but is closed in the next.
• In the scene in the hut on the rock, where Hagrid comes to fetch Harry, Harry's T-shirt is hanging off his left shoulder at the beginning of the scene, and then it is in the center of his chest, then hanging off the left again, and then back to center.
• In the scene with the flying keys, we can see the string holding up the broomstick just before Harry grabs it.
• According to the book, Hogwarts students reach the train by going through platform no. 9¾, which is secretly located in the barrier between platforms 9 and 10. In reality, platforms 9 and 10 are in separate buildings, and there is no barrier between them, but railway tracks. People wrote to Rowling about this, and she admitted getting confused between King's Cross and Euston stations. The Platforms actually used in filming are platforms 4 and 5.
• At Kings Cross the camera crew is reflected on the side of the train on the right.
