Question: In the book, whenever someone used the polyjuice potion to change into another person, their voices changed too. In the film their voices remained the original, it didn't change into the voice of the person they were transforming into. Can someone tell me what prompted the makers of this movie to make this change?
Question: No kids in the whole school go into the girls toilet because of Moaning Myrtle. Clearly even Dumbledore would know about this. Not judging Dumbledore, but wouldn't he have asked Myrtle at least 50 years ago when the chamber was re-opened after Myrtle died?
Question: In the trivia section it says "A trait of J.K. Rowling is to make up names that are pertinent or descriptive of their object/person (eg. Diagon Alley, Voldemort, etc)." I understand Diagon Alley = Diagonally, but what does Voldemort describe?
Question: Someone submitted in the trivia section that there's a shop in Knockturn Alley where the entire set of Harry Potter books are in the window. I couldn't find them. Are they really there? I think if they are, they might be the British version of the books, and I have no idea what they look like.
Question: Towards the end of the film, when Harry and Lucius are talking after leaving Dumbledore's office, after Dobby stops Lucius from casting a spell on Harry, Lucius says, "You're parents were meddlesome fools too". I don't recall any indication in the book that Harry's parents knew the Malfoys. Obviously the Malfoys probably knew the Sirius Black/Peter Pettigrew storyline that is explained in PoA. I seem to recall something in one of the last two films where Voldemort discusses something about the Potters with Lucius.
Question: Is there some reason why Lucius wanted to give the diary to Ginny in particular? Why did he not give it to someone else years ago, allowing Voldemort to return sooner?
Question: There is something about wizards I don't understand. Why do they keep their magic a secret?
