:::Quality doesn't matter, it's popularity. One Flew Over the Cuckoo's Nest made $100,000,000, and if ticket prices were what they are now, it would have made much more than that. I can honestly say that a lot of the people who saw the movie (which is more exposed to people) haven't heard of the book. A disambig page is not needed for a subject with two articles. Keep the movie on the main page, and link to the book page right away. Like 2001: A Space Odyssey does. And like how The Godfather links to the disambig page. -
