Corrected entry: As the first years take the boats to Hogwarts, the camera goes from boat to boat. Neville can be seen on two different boats.
Corrected entry: As Harry purchases the candy on the train, we see a large body of water outside the train window. The next shot shows the train going through a dense forest. When the boys start eating the candy, the view from the train is again the body of water. If Harry and Ron are typical boys, they wouldn't wait very long to start eating their candy; certainly not long enough to pass through a forest and return to the shoreline. (00:35:12)
Corrected entry: At one stage in the sea hut scene, Harry is standing beside the BARE wall of the fireplace. The camera then goes to Hagrid, who turns and pulls the broken door down saying "Unless you'd rather stay, of course?". The camera then goes back to Harry, who is stil by the wall that now shows his coat is hanging right there beside him, which Harry then grabs on his way out. (00:17:21)
Corrected entry: In the scene where Harry is looking at the book titles in the Restricted Section, he quickly pulls off his invisibility cloak. When he does, you'll notice that through the invisibility cloak you can see the book shelf and everything, except for the lantern Harry is holding. The lantern just disappears while he pulling the cloak off.
Corrected entry: When Harry is 'talking' to the snake at the zoo, he is speaking in English, so viewers can understand it. We know that Harry is a Parselmouth (he can talk to snakes). However, in the 2nd film - Harry Potter And The Chamber Of Secrets - when Harry is confronted with snakes he speaks in Parselmouth - the language we can't understand. Why is it that he is speaking to the snake in English, and not hissing sounds?
Corrected entry: A plot hole about Quirrell getting through the puzzles with no lingering effects was corrected by saying that they probably reset themselves afterwards, which makes sense. However, this itself creates a mistake - if the challenges to get to the Philosopher's/Sorcerer's Stone reset themselves after each person, how is it that the winged key is injured?
Corrected entry: When Harry, Ron, and Hermione first go into the forbidden corridor, the pillars that burst into flame for light do not begin until after a person would be walking through the hallway. However, Harry's face is lit when he turns around to see Filch's cat (Mrs. Norris). If the first fire is behind him, why isn't his face in a shadow?
Corrected entry: In the scene right after the Quidditch game (when Harry, Ron, Hermione, and Hagrid are walking through the brick tunnel thing) Ron's scarf is like Harry's - one part over his shoulder, hanging in the back, and the other part of the scarf in front. But when they all walk forward more, and the camera gets closer to them, Ron's scarf is hanging over both shoulders.
