Corrected entry: If you have the (US Version) DVD set on subtitles, when Harry is in the hospital wing after quidditch, you hear one of the Weasley twins talking. He says "Let's walk you off the Astronomy tower." The subtitle says, "Let's walk you off 'a tower'." (00:56:30)

Correction: It's quite common for subtitles to not include all words spoken by characters. As you could imagine, the subtitles could very well fall behind the action on screen or have to speed up if every last word appeared on the screen.

Corrected entry: It is awfully light in the hospital wing when Dumbledore tells Hermione to use the Time Turner, considering that the action just beforehand took place in definite darkness.

Correction: The reason that it's so brightly lit in the hospital wing is that it's full moon. Lupin has just become a werewolf. You can see the same kind of brightness the night that Lupin (who has just been, as Snape remarks 'on a nightly stroll'), confiscates Harry's Marauders Map.

Corrected entry: After Harry faces the boggart which changed into a dementor during the Defense Against the Dark Arts class, Lupin tells the class to go. Harry still stares at the spot where the boggart was. If you look closely you can tell the shot was reversed for Harry's scar is on the wrong side of his forehead.

Correction: This is simply because this is clearly shot as the reflection in the mirror set into the cabinet, which you can see as the camera moves into the mirror (the wooden edges can be seen).
