Corrected entry: In the scene where Harry, Ron, and Hermione have fallen through the trap door and are caught in the devil's snare, Harry yells "Hermione, where are you?". If you watch closely he is not wearing his glasses when he says this. In the next shot, he is.
Corrected entry: When Harry tries to open the door on the third floor, if you look closely you will notice that the wall which moves in is actually a curtain painted to look like a rock wall.
Correction: After viewing the scene many times it looks to me as though what we are seeing waving in the draft is a bunch of cobwebs, not the entire wall.
Corrected entry: When the Durselys and Harry return from the zoo, as the door is just about to shut you can see the crew equipment and boxes outside the door.
Correction: I watched the scene in question in slowmotion, there isn't enough time to show boxes or equipment outside because the bodies block the doorway until Uncle Vernon closes the door and all you can see outside is the house across the street. The "boxes" that you may have seen are the windows which can be confirmed when Vernon leaves for work.
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: Hermione says on the train, "I tried a few spells, but they've all worked for me." Underage witches and wizards aren't allowed to use magic. How could she have tried a few spells?
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)
Correction: It's quite possible there's a lake in the forest. Beyond that, this sounds more like artistic license than a mistake.
Corrected entry: Harry, Ron, and Hermione go into the forbidden hall after the staircase moves, believing there is no other way out, when in fact there is a second staircase right in next to the door.
Corrected entry: In the overhead shot of Olivander's wand shop, you can see three wands on his desk that are in a fanned out position. Then when Olivander is handing wands out to Harry, the wands are straightened out. (00:24:06)
Correction: Mr. Ollivander puts the box from the first wand on top of the three wands. This would make the wands roll and change positions.
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)
Correction: Actually Harry's coat is hanging on the wall the whole time, you just really have to look close. The coat is hanging a little lower than Harry, but there are angles where you can see it there before he picks up the coat.
Corrected entry: When the centaur speaks to Harry in the Forbidden Forest the close up shot shows tape around the bridge of Harry's glasses. In the next shot the glasses are once again repaired.
Correction: On a High Definition television, you can see that there is no tape on Harry's glasses-it is just the way the lighting is reflecting off of the bridge of his glasses.
Corrected entry: In the scene where Ron, Harry, and Hermione play chess, Ron, the knight, is directly next to the Queen. In chess, the knight is placed next to the castle and the bishop goes next to the queen.
Corrected entry: In the scene when Harry is sitting in the dark looking at the mirror, just before the old man comes from behind to talk to him, you can easily see the shadow of a camera man and camera on the wall.
Correction: After seeing this mistake on the site, I started watching that scene very carefully. The only shadow I can see in that scene is Dumbledore's shadow as he approaches Harry.
Corrected entry: When Harry is looking at Mr. Olivander's Wand Shop from the outside the windows are VERY rounded, yet when Harry is inside the shop they are either totally flat or at most a little bit rounded - definitely not as much as the outside.
Correction: The view of the outside of the wand shop shows a different part of the store. Where the doors are, the windows are flat. That is what we see in the view from the inside.
Corrected entry: Supposing Hermione followed Harry's advice and somehow went back through the puzzles and took the one single broom to get out of the dungeon (leaving Harry alone with no method of escape), how could she do that with the burden of taking the unconscious Ron with her?
Correction: Supposedly, as it says in the book, Hermione didn't even leave with Ron to find Dumbledore. Dumbledore had already come back, and he had gotten through Fluffy and was on the way in as Hermione was preparing to leave and go warn him.
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.
Correction: The books can be seen because they are outside the cloak. The lamp is invisible for a second because it is inside/along the lined part of the cloak.
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?
Correction: The reason that the key for the door is still injured is its supposed to be like that so you can find it in the room.
Corrected entry: When the troll is discovered during the Halloween banquet, Percy supposedly leads all of the Gryffindors back to the common room. The amount of Gryffindors that follow him aren't nearly as many as those seen at the Gryffindor table during meals.
Correction: Percy is only taking the first years to the common room, the others know how to get there.
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?
Correction: It's the light from the open doorway.
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.
Correction: Actually, the scarf always remains on both shoulders, it's just a bit difficult to see when Ron is far from the camera.
Correction: If you look really closely, you can see the light reflecting off the left corner of the glasses.
