Hollywood has been mixing up books and movies for a long time now and one of the foremost things that every book reader knows is that none of these adaptations of books into movies have been true to the original storyline.
There have been many instances where many of the things in the storyline has been horribly altered or even deleted entirely.
For instance, when the Harry Potter series of books were adapted into movies, Peeves The Poltergeist was completely absent from the entire series of movies and also certain facts related to both Voldemort and Severus Snape were altered to suit the movie storyline.
