Why are the Harry Potter movies so different from the books?!
Question:
Why are the Harry Potter movies so different from the books?
Answers:
General calculation is one page of script for every minute of movie. Some of these books are over 500 pages. Plus, it is difficult to translate from the book a character's internal dialogue, you'd have to have a narrator in the movie.
You don't want a narrator in Harry Potter, do you?
