Welcome to Harry Potter Answers. What would you like to know?

Well, the possession has many different aspects in the movie, as it is longer, and Harry uses all friendship in love, rather than just the love for Sirius, to drive him out. So this could have been another changed thing, as he definetely couldn't see in the books, but we have no proof Harry seems the friends coming in in the movie.

ALso, in the books his friends are hurt much worse and therefore there wouldn't be the chance for him to see them.
