2nd Sep 2004
Revealing mistake: At the start of the overhead shot as the troll's club smashes the cubicles, while Hermione lies on the ground, the top beams of all the cubicle walls and the front door of the second cubicle are all visibly pre-broken before the club slams into them. (01:10:15)

16th Jul 2008
Continuity mistake: When Wood takes Harry out to see the Quidditch balls, he sets down the bat right against the box holding the balls. When Wood goes to open the box, you see the grass where the bat should be. And then he picks up the bat, which is not where it was originally placed. (01:01:30)
28th Apr 2006
Continuity mistake: When Hedwig comes flying in delivering the broom, she drops it at an angle, but when Harry catches it it's completely horizontal. (01:11:50)
1st Jul 2003
Continuity mistake: In the scene where Harry, Ron and Hermione come with Filch to Hagrid to go into the dark forest, watch the lamp Hagrid sets down. Filch says something like "A sorry lot this, Hagrid". Then the shot cuts to Hagrid (look at the lamp) then to Filch again who says "Oh good god man, you're not still on about that bloody dragon, are you?" then to Hagrid again. The lamp changes position between these shots. (01:43:00)
9th Sep 2006
Continuity mistake: In the Quidditch scene, when Madame Hooch steps onto the field she says, "Now I want a nice, clean game," and while she's looking up, her Hogwarts patch is on the left side of her robes. At the end of the Quidditch game when she says, "Gryffindor wins," her patch is on the right side of her robes. Interestingly, the shot of Madame Hooch is a flipped shot, yet it was pasted onto the scenic background, which is not flipped, but properly positioned. (01:23:00)
26th Aug 2003
Revealing mistake: During the Quidditch game, none of the players have shadows on the ground. (01:16:20)
23rd Aug 2004
Continuity mistake: At the hut on the rock, Harry lies on a grey blanket spread on the ground between the fireplace and the couch. When Hagrid bangs on the door, Harry quickly jumps up and hides, leaving the blanket behind. Though the blanket is visible on the ground, in some shots, it is however, gone in the three wide shots with the Hagrid body double, as he zaps a tail on Dudley, then as all the Dursleys run upstairs, as well as the shot after Hagrid says, "We're a bit behind schedule, best be off." (00:12:55)
18th Aug 2004
Revealing mistake: After Madame Hooch takes Neville to the hospital wing, Malfoy takes the Remembrall and mounts his broomstick, on a convenient protruding metal rod. Then when he comes around, though the students step away and watch as he begins to fly off, many of their eyes are not level with Malfoy, as he is merely edited into the end of this shot. (00:57:50)
2nd Sep 2004
Continuity mistake: When Madame Hooch leaves with Neville to go to the hospital wing, Seamus holds his broomstick with the bristles on the ground as Malfoy ridicules Neville. However, as Malfoy steps on his broomstick and then flies away, the bristles on Seamus' broomstick are now at the top. Then when Harry takes off on his broomstick, the bristles on Seamus' broom are on the ground once again. (00:57:30)
27th Aug 2001
Continuity mistake: After the final confrontation Harry has scratches on his face, particularly one on his chin. When visited by Prof Dumbledore the chin scratch is barely there but in the scene in the refectory it is back and appears larger than before. (02:14:00 - 02:17:50)
21st Aug 2004
Continuity mistake: When Madame Hooch approaches and then welcomes the class to their first flying lesson, the angle at which their shadows are cast changes dramatically in consecutive shots throughout this scene; and in some shots there are no shadows. (00:55:00)
21st Apr 2008
Continuity mistake: When Snape enters the classroom during the first Potions class, there is a lit candle and an hourglass on the desk directly behind him. But in the following shots the candle and hourglass change positions and move farther away. (00:49:20)
11th Sep 2002
Continuity mistake: In the chess scene, at the end of the (overlong) montage of shots of pieces being smashed, the White Queen turns her attention to a Black Castle. The first stroke of her sword clearly goes through the structure of the castle, which disintegrates. We cut to various different angles and watch pieces of the destroyed castle flying all over the place. Cut back to the original angle, and we see the Queen attacking again, but the Castle is completely intact - only the figure from on top of it is missing. And it can't have been the second castle, since that's Hermione's position. (01:58:26)
16th Aug 2004
Continuity mistake: As Hermione hides under the sinks the troll smashes the front basin of the second sink on the right, leaving its faucets and surrounding sinks intact. Though in a view of the entire lavatory when the troll holds Harry upside down, from behind Hermione, the entire second sink, its faucets and trim are entirely missing and the entire fourth sink, which was never touched, is as well, both are gone. When the troll is knocked out, as Hermione stands up and moves toward Harry and Ron, though the faucets of the second sink are back, the front basin of the second sink is visibly broken again just as in the original shot, and the entire fourth sink is still inexplicably gone in this shot. (01:10:45 - 01:11:45)
13th Sep 2004
Visible crew/equipment: Hermione opens the door to Fluffy's room when she says, "Alohomora!" so she, Harry and Ron could hide from Filch and Mrs. Norris. As Ron closes the door the top of the third floor corridor set is visible at the top of the screen. As an aside, when Ron repeats, "Alohomora!" look at Hermione's face. (01:02:00)
16th Aug 2004
Continuity mistake: At the hut on the rock, after the camera pans sleeping Vernon and Petunia, there's an overhead shot of Harry and Dudley downstairs. In this shot the hanging light, its switch and cable are visible over the stairs. Note, the cable switch hangs down low, parallel to the droplight. However, when Vernon and Petunia are at the stairs, and she turns on the light, the cable and switch are now perpendicular to the droplight, raised higher up parallel to the wood above. Seen in following shots as well. (00:12:25)
25th Jun 2021
Continuity mistake: On his first night in the castle, Harry is sat on a window ledge with Hedwig. In this shot, his feet go from resting on their sides and crossed at the ankles to flat and uncrossed. (00:48:50)
9th Feb 2004
Continuity mistake: At Kings Cross, just as Percy Weasley is about to run through the wall onto platform 9 3/4, we see a man and a woman walking past him, but when the shot changes direction, they have both disappeared. (00:31:15)
27th Sep 2004
Continuity mistake: The way in which Mr. Ollivander holds out the second wand for Harry to try differs, in the shot facing Mr. Ollivander and the next shot facing Harry. (00:26:25)
