Corrected entry: In the scene where Snape takes over the Defense against the dark arts class, (about werewolves) when the projector changes slides, on the screen the image moves clockwise at the top. However, when you see the projector, the light enabling a picture to be projected is on the bottom and the slides rotate counter clockwise.

Correction: Many projectors flip the image, showing it on the screen upside down and backward to the film's orientation. This must be one of those projectors.

Corrected entry: Hermione says that Harry wouldn't want to run into himself in the past, that he'll go mad. There have most likely been many instances when something like that would happen, a polyjuice user encountering the sample, for instance. It would probably cause confusion, but it's very unlikely that someone would go insane as a result.

Correction: She meant Harry's past self, who doesn't yet know about time-travel, would. At any rate, it was a figure of speech. Not that he'd just start drooling in his Cheerios with an Aluminum foil hat on his head at the mere sight of himself. Just that his past self's reaction could be dangerous.

Corrected entry: When Peter Pettigrew is seen on the Marauder's Map, his dot's footprints are displayed as that of a human's even though he is in his rat form. However, during the credits Sirius' dot is shown changing from human footprints to dog pawprints and back again. Either Peter's prints should've shown up as rat prints or Sirius' should have consistently been shown as human prints.

Correction: That was just something cute they did for the credits, it isn't meant to be taken as film canon. The Marauder's Map shows what is truly there; Peter Pettigrew is a human whatever shape he may take, so his footprints appear on the map as a human's.
