Harry Potter and the Prisoner of Azkaban mistake picture

Continuity mistake: When Harry is in Lupin's office, as the Professor says, "I resigned..." his cane leans against the corner of the trunk beside the doorway. Yet when Harry says, "But Dumbledore..." the cane hangs off the center of the trunk. As Harry says, "None of it made any difference," the cane is gone, but when Lupin says, "You helped uncover the truth," the cane hangs again. Then when Lupin says, "If I am proud of anything..." the cane leans against the corner, but wait, when Lupin leaves the office the cane hangs off the trunk once again. (02:06:10)

Plot hole: Harry never notices that the name "Peter Pettigrew" appears on the Marauder's Map, right next to "Ronald Weasley." Way beyond a character mistake, as there's no way that wouldn't be cause for interest. If nothing else, Ron's brothers who had the map for years before giving it to Harry, would most certainly have wondered why their brother was sleeping with a person named Peter Pettigrew.

Suggested correction: JK Rowling explained why Ron's brothers didn't wonder why Ron was sleeping with a man named Peter Pettigrew. Here is the link: https://scifi.stackexchange.com/questions/11447/why-couldnt-harry-or-anybody-else-see-peter-pettigrew-aka-scabbers-on-the-marau.

Continuity mistake: Between the shots of Marge floating out of the house and later when Petunia runs to Vernon on the grass, there are many significant changes. The short brick walls that edge the Dursley garden are actually different bricks, different grout and are even aligned differently between these shots. The bushes along the wood fence are at least 2-3 ft away from the corner bricks in the first shots, but in the last shot are aligned with the corner. The height of those bushes go from being way above the top of the wood fence to being at least a foot below. In the first shots there are small metal plaques that are attached along the top of the wood fence, but in the last shot they are gone. (00:05:30)

Revealing mistake: Right at the start when Harry is on his bed and making a light under his sheet, you can see that he is actually on something like a light panel in order for this effect to happen. For one thing, when he moves around on it, it doesn't bend like a mattress does. Also, about halfway down the bed you can just see where the sheet ends and this panel begins. (00:00:50)

Continuity mistake: During the scene where the Fat Lady is missing, the students are gathered on the stairs and Fred and George are on the top of the stairs, right next to each other. In the shot right after Ginny says, "The Fat Lady, she's gone," one of the twins is on the left, at the foot of the other staircase. He could not have moved that fast, because the two are standing beside each other when Ginny talks. (00:46:05)

Continuity mistake: When Harry first sees the Patronus with Sirius, from Harry's POV it is clear that the Patronus light contracts entirely into the wand, while the area around the wand is still visible, and then he collapses. However, when Harry casts the spell later into the movie, Harry collapses on the other side of the lake, while the light from the wand is still quite large. (01:41:00 - 01:57:00)

Continuity mistake: When Marge insults Harry's parents, Harry gets angry and screams "Shut up." In the very next shot, from behind Petunia, Petunia turns her head behind to look at Harry. The next shot is a side on/wide shot and Petunia's head is not turned behind, in fact she is now looking in Vernon's direction. In the next shot, which is again a shot from behind Petunia, she is looking behind again.

Continuity mistake: When the kids are on the Hogwarts Express, there is a bottle of water on the flat fold up tray near Lupin. As the train is bumped, Ron is jerked forward, but the bottle remains in the same position. (00:20:40)

Continuity mistake: Immediately after Remus' and Sirius' fight (as werewolf and animagus dog), a wounded Sirius stumbles down a pathway towards the lake. Harry is only a few steps behind him. When the scene cuts to the next shot, Harry is now running down a wooded slope alone and spots Sirius lying next to the lake. Sirius, in his weakened and injured condition, could not have sprinted so far and so quickly ahead of Harry. The terrain isn't steep enough for Sirius to have rolled all the way to the edge, and he wouldn't have had time to get up and continue walking. (01:41:50)

Continuity mistake: As the Knight Bus begins to appear, Harry falls back onto the ground, leans on his arms and in the front shot his sweatshirt is off his right shoulder, but in the next side shot, as he still leans on his arms, both sides of his jacket are properly on. (00:07:55)

Continuity mistake: In the Shrieking Shack, Harry grabs Sirius Black and throws him to the floor. There are many black marks on the floorboards, like paw prints etc. Although Sirius doesn't move when Harry first throws him on the floor, the black marks on the floorboard near Black's head change between the first wideshot of him on the floor and the following closeup and in subsequent shots as well. (01:27:25)

Revealing mistake: After Harry's first ride on Buckbeak during Hagrid's class, before Buckbeak cuts Malfoy's arm with his talon, when Malfoy holds his arm over his face, the pre-cut and ripped sleeve is visible in this close-up. (00:37:55)

Continuity mistake: When Hermione and Harry hide behind the pumpkins, Hermione says, "Come on! We're coming out the back door. Go!" As HRH run out of Hagrid's, Hermione and Harry run to hide behind the trees. In the shot facing the two, with the pumpkins and Hagrid's behind them, the blanket on the ground beside the pumpkins is visible, though it is gone thereafter. (01:52:00)

Super Grover

Continuity mistake: When Dudley is hit by the first button that flies off Aunt Marge, we can see a table beside him with a lamp and a picture on it. When it cuts to Dudley lying on the floor, we can see the lamp and the picture have changed position. (00:04:50)

Continuity mistake: When Fred and George give Harry the Marauder's Map, Harry opens it up and on the right is Dumbledore's study. In the close-up shot of Dumbledore's study, the map is drawn with much more elaborate detail for fun and dramatic flair and the actual words of the interlocking circles are written on the map extremely differently than the previous shot. (01:00:00)

Super Grover

Continuity mistake: In the first exterior shot, as the Dursleys eat dinner, both sides of the kitchen window (above the patio set) are closed. When Harry says, "Oh yeah, I've been beaten loads of times," the right side of the window is clearly open, as the window's diamond shaped pattern is only towards the left side. It's also visible when the lights flicker and the window curtain on the right blows in. In the last shot, as Marge floats away, both sides of the window are closed again. (00:03:10 - 00:05:45)

Continuity mistake: When Harry boards the Knight Bus in the exterior shot, the curtain in the small window at the stairs is pushed open towards the outside of the bus. However, in the next interior shot the curtain is pushed open towards the inside of the bus. (00:09:00)

Continuity mistake: When Sirius flies off on Buckbeak, the ground on which he takes off from is a perfectly clean stone ground with nothing on it. Yet after Sirius has flown off, Harry and Hermione run across the same ground, only now it is covered in dead leaves, grass and mud, etc. (01:59:40)

Hamster

Continuity mistake: When Aunt Marge's chair starts to float up, in the close-up of her legs, her feet are at least a foot off the ground and the chair even more. However, after her necklace pops, Vernon yells, "Down boy!" at Ripper, she lets go of the table and in the next wide shot, her feet are still well under the table and the chair is still touching the floor - this shot is spliced from the earlier shot, just after Ripper first bites Vernon's foot! (00:04:50)

Super Grover

Continuity mistake: During the dinner scene at the Dursleys, Dudley is shown in a close-up watching a game-show where a young woman is putting on large headphones. But when the shot returns to the whole room, you can see the girl on the TV putting on the headphones all over again. (00:02:30)

Sirius Black: Brilliant, Snape. Once again you've put your keen and penetrating mind to the task and as usual come to the wrong conclusion.

Question: When Fred and George were in possession of the Marauders Map, before giving it to Harry, how come they never wondered why Ron was always hanging around with a person called Peter Pettigrew? He shows up on the Map even whilst disguised as Scabbers, as we know from when Harry spots him.

JBrock

Chosen answer: Fred and George used the map to aid them in their mischievous activities at Hogwarts, and probably had little interest in what their little brother was doing or who he might be with at any given time.
