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.
Question: In the first scene, Harry is seen practicing his 'Lumos Maximus' spell under his bedcovers. But in film 5 (and the books, for that matter) it is said that students aren't allowed to perform any magic outside of school. So how was he able to perform this spell without being warned/expelled from Hogwarts?
Question: Not sure if anybody will have an answer to this, but I would appreciate any good guesses. I read the book and it describes Remus' suitcase as having the name "Professor RJ Lupin" in "peeling" letters, so the letters have been there for a while. Did he teach at Hogwarts in the past, or could there be smaller magical schools in Britain?
Question: Near the end of the film, from Buckbeak's execution, there are things that relate to Harry and Hermione going back in time, like the stones being thrown through Hagrid's window, and the wolf howl etc. But if they had already gone back in time to do these things, then wouldn't Buckbeak and Sirius have already been saved, meaning that they wouldn't have to go back and do all that in the first place?
Question: On the 2nd Disc, there is an interview with director Alfonso Cuaron and J.K. Rowling. In the interview, Rowling states that Cuaron unknowingly put some clues in the movie that foreshadow events that happen in books 6 an 7. I have read books 6 and 7 and I re-watched the movie, but I still have no idea what clues Rowling was referring to. Could someone please fill me in?
