I tend to favor the books over their films, but I can appreciate both. For example, I think the Harry Potter books were better than the movies, but I still love the movies. There might even be some films I prefer to the original books. I can't think of anything offhand (probably the English major in me blocking them out), but I relatively certain it's happened before.
One of my policies when it comes to books being made into films is that I have to read the book before I see the movie. I never wittingly break this rule... But I have broken it because of lack of Googling. I watched the last summer's Something Borrowed without knowing it was a book first. I still haven't read the book because I don't have enough free time to dedicate to it, but I certainly plan to do so. I loved the movie, so I'm actually pretty excited about reading the book.
There are some films I will put off watching until I finish the book- like I did with the movie The Help. The problem with that is sometimes I miss seeing the film in theaters, which is a little disappointing.
Here are some trailers for movies based off of books that will be coming out soon:
How about you? Do you prefer books or films?
