Super Grover

Revealing mistake: Just after Harry attacks Snape at the Shrieking Shack, he insists on knowing about Peter Pettigrew. In the next shot, as Lupin says, "He was at school with us. We thought he was our friend," there are wedges under the wheels of the piano, however, in the following shots they're gone. (01:34:10)

Revealing mistake: In the Shrieking Shack, when Harry sends Snape flying into the bed, the canopy collapses in the stunt. In this shot the metal bars at the top of the canopy frame are visible, whereas in the following shots it is no longer there. The way the canopy frame actually hangs after stunt differs considerably and the draperies hanging on the bed differ in the shots prior, during and after the stunt. (01:33:55)

Revealing mistake: While being hurled around by the Whomping Willow, Hermione grabs hold of Harry's shirt in the close-up. In the next shot as Harry's being lifted up, the bottom of the left side of his blue tee shirt is pinned to his pants, also visible in another shot. (01:29:30)

Revealing mistake: In the first overhead shot as the Dementors swoop down towards Sirius and Harry, Sirius lies in a particular position. During the Dementor attack his clothes move, then after Harry's Patronus repels the Dementors, Sirius breathes again and he now lies flat. After Harry collapses, in the last overhead shot, Sirius and his clothes lie in precisely the same position as the first overhead shot. His position differs later, in the repeat timeline as well. (01:42:50 - 01:45:20)

Revealing mistake: At the Shrieking Shack, when Harry shouts, "Expelliarmus!" there is a nice close-up of Snape and it is obviously not Alan Rickman flying backwards onto the bed. (01:34:00)

Super Grover ★

Revealing mistake: While he sits by the Whomping Willow, Ron shouts, "Harry, Hermione, run! It's the Grim!" When Sirius the dog runs toward them, in the shot facing Harry and Hermione, their eyes are not quite in sync with the dog before it leaps. (01:28:00)

Super Grover ★

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)

Super Grover ★

Revealing mistake: During the DADA class, as the Boggart balloon flies by, Lupin's eye contact with the balloon, as well as others', are not quite in sync as they follow the balloon with their eyes. (00:44:15)

Super Grover ★

Revealing mistake: During the DADA lesson with the Boggart, the body double for David Thewlis (Lupin) is quite evident in some close range, head on and side shots. As a matter of fact, Emma Watson's and other actors' body doubles are very noticeable in many shots not involving a stunt. (00:44:15)
