As you can see, five out of the top ten movies from last year were based on books, and one spawned a book of the same name at the same time as the movie. Not all of these books were popular before the films, but after the films; the books definitely earned more readers. The best-selling novels often turn into the best-selling films--Harry Potter and the Lord of the Rings trilogy--and I don't see this changing anytime soon.
