• Continuity: In Diagon Alley, Harry and Hagrid walk past the same cart and storefront three times. In the opening wide shot, they walk past the purple storefront with the yellow moving scissors and the cart of market goods in front of it. Three shots later, the storefront and cart are shown again in detail, as Harry and Hagrid pass. The next shot shows them passing the cart (with a stack of cauldrons in the background).

• Continuity: When Ron gets drooled on by Fluffy and gets wet, but two shots later he's completely dry.
  
  
• Errors in geography: When Harry arrives at Hogwarts, Professor McGonagall announces that the Sorting Ceremony will begin "momentarily". In UK English, momentarily means "for a moment" (i.e. briefly), and a Scottish witch as pedantic and precise as McGonagall would never use the American meaning of the word ("in a moment" or "soon"), even though the American meaning might be well understood. Then again, given that the otherwise equally pedantic Snape says "less" when he means "fewer", it could just be that the teaching staff's use of English is just as sloppy as it is in schools all over the muggle world.
  
  
• Continuity: 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.
  
  
• Audio/visual unsynchronized: When Harry and Ron are fighting the troll in the girl's toilet, they use a spell to lift the troll's club over its head and drop it. The club does hit the troll and makes an appropriate sound effect, but then the club falls to the floor, it makes no sound at all.
  
  
• Incorrectly regarded as goofs: Many viewers believe that the infant Harry in the flashback is wearing anachronistic Blue's Clues pajamas. The design on the sleeve is actually a rabbit.

• Continuity: When Harry, wearing his Invisibility Cloak, spies on Professor Quirrell being bullied by Professor Snape, the shots filmed from Harry's point of view have him at eye level with the adults even though he is clearly shorter than they are.
  
  
• Continuity: 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.
  
  
• Audio/visual unsynchronized: In the scene following the defeat of the troll, Quirrel is shown speaking with the other professors, at which point they, and the trio, leave the girls' bathroom. Their footsteps are clearly heard as they move down the hall; however, in the next shot of the troll laying on the floor, the sound effects have ceased. In the last shot, of Quirrell jumping nervously in response to the troll grunting, the footsteps can again be heard.
  
  
• Continuity: When Mr. Dursley is talking about how there's no post on Sundays and the first letter shoots out of the fireplace, the log poker is in the middle of the hearth, when all the other letters come shooting out, the poker is on the right side.
  
  
• Miscellaneous: When Filch enters the Restricted Section of the library in search of the disturbance, he passes Harry, who's hiding under the Invisibility Cloak. The camera angle leads the viewer to believe Harry is as tall or taller than Filch. Harry should be a foot or two shorter.
  
  
• Continuity: When the troll attacks Hermione the first time, its club demolishes the first three stalls. Right before the troll swings its club again, the door of the second stall is still standing.
  
  
• Factual errors: 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.
  
  
• Continuity: During the first meeting of Harry, Ron and Hermione on the Hogwarts Express, Hermione's tie changes from being crooked to one side, to straight then back to crooked again
  
  
• Revealing mistakes: When Harry and Hagrid are in the Bank at Diagon Alley. Hagrid gives the goblin a card. Multiple time through camera shots the cards corners have been bent and smoothed.
  
  
• Crew or equipment visible: When Harry takes Ron to the Mirror of Erised, when Harry drops his cloak and runs away, you can clearly see the lime green from the outside.

• Crew or equipment visible: At Kings Cross the camera crew is reflected on the side of the train on the right.
  
  
• Continuity: After Harry gets sorted into Gryffindor he goes and sits down next to Ron with Hermione across from him who is sitting next to Percy. In the next shot when Harry asks who's that teacher next to Professor Quirrell he asks Percy and Hermione is sitting to the right of him and Ron is across from him.
  
  
• Continuity: After Harry has received his wand in Ollivander's, his hair is parted to show his scar. However, when Hagrid knocks on the window and Harry sees Hedwig, his scar has mysteriously disappeared.
  
  
• Revealing mistakes: When the multiple letters fly into the house from the fireplace, Harry catches one out of the air and it is obviously a single sheet of paper rather than a stiff envelope like the first one that was delivered and opened.
  
  
• Continuity: When Harry is in the restricted section, he sets down the lamp to his left before taking off his invisibility cloak, setting the cloak to his right. When Filch's voice is heard and Harry grabs the cloak, the lamp is on top of the cloak and thus falls onto the floor.
  
  
• Revealing mistakes: When Aunt Petunia is cracking the eggs and finding they are filled with letters rather than yolks, the envelopes are clearly a thin sheet of paper, not a thick envelope with a letter inside. (You can tell they are envelopes because you can see one is addressed the same as the previous envelopes)
  
  
• Miscellaneous: When Harry is quoting the article about Gringotts being broken into, he reads "... the vault in question; number 713...” however if you look closely at the article shown, it does not mention the vault number. Everything else about his quote is accurate, however.
  
  
• Revealing mistakes: In the very beginning of the movie, Dumbledore is walking towards McGonagall who is still in cat form. As he is walking, you can see his shadow cast against a backdrop of trees.
  
  
• Continuity: When Harry is upside down with the troll holding him by his legs, his hair is pointing to the floor and his scar is no where to be seen on his forehead.
  
  
• Continuity: During the oversize chess match, Hermione is supposed to be the Queen's side castle or rook. In the fighting the white Queen is clearly shown destroying two black castles. The two white castles are shown intact later in the game, so that would mean there were one too many black castles or rooks on the board.
  
  
• Miscellaneous: In the scene where the owls are dropping the gifts, a girl near the top left corner misses it and it hits the floor.
  
  
• Plot holes: At the end of the film, when Dumbledore is announcing house point totals, none of the totals end in a 5 or 0. Yet throughout this film, and all other HP films, points are always awarded or taken away in numbers ending in 5 or 0.
  
  
• Continuity: When Voldemort is choking Harry and Harry grabs Voldemort's hand, Voldemort "disintegrates" due to Harry's touch yet moments earlier, Voldemort is touching the skin on Harry's neck with no effect.
  
  
• Continuity: In Gringotts, when Hagrid showed the letter from Dumbledore, it was wrinkled at the ends. But when the goblin held it, the wrinkles were gone.
  
  
• Revealing mistakes: At the end of the chess match, Ron is supposedly knocked unconscious. When Harry and Hermione run to check on him, Harry touches Ron's arm and Ron's mouth twitches.
  
  
• Continuity: In the scene where Harry and the Dursleys are getting into the car before going to the zoo, Vernon is seen speaking to Harry. From the backside, Harry's button up plaid shirt is seen on his shoulder, then from the front it is hanging off his shoulder.
  
  
• Revealing mistakes: During the Quidditch match after Hermoine looks at Snape through the binoculars and says "It's Snape! He's jinxing the broom!" You can see Ron mouthing her lines along with her.
  
  
• Continuity: At the beginning of the movie, when Harry Potter is dropped on the doorstep of the Dudleys (after his parents' death), he is clearly an infant. However, in the album that Hagrid gave Harry at the end of the movie, there is a picture of Harry as a toddler with his parents. If at the beginning of the movie he was an infant when he was orphaned, then it is not possible for him to have a picture with his parents when he was a toddler.
