Now, to start this off, let me first say that I really like the LotR movies, and I've seen several other book-to-film conversions that ended up being very solid movies. However, I think that the process is rarely successful, more often ending with a lifeless film that hews too closely to a scene for scene copy (The fourth Harry Potter movie was particularly egregious in this), or with a bizarre new movie that more or less works cinematically, but has nothing to do with the original story. (I'm thinking here specifically of Nightwatch, which was just awful and had nothing to do with the books themselves, or of I am Legend, which was a lovely zombie movie that had nothing to do with the actual story save that it involved a man and a dog.) Basically, if I were ever offered a chance to do a film on my stories, I think I would turn it down. I've read too many things from too many authors - even ones who were given full creative control - that make me think it's simply not worth it. It comes down to a difference in mediums; movies are very good at telling certain kinds of stories, and in telling stories in certain ways. Books are very good at different stories, and different storytelling methods. The two have very little common ground. Even if the author has total control of the film and one doesn't have to worry about stories getting "the Hollywood treatment" (a la the "better" ending to Hunchback of Notre Dame), one still often has a major hurdle: writing a novel has nothing to do with writing a screenplay. Harlan Ellison talked about this a lot in his long-running movie review article. Basically, while I can think of a few movies made from books that ended up making good films, I can think of far, far more simply awful ones. Also, I have trouble thinking of any movie made from a book that succeeded in telling the same story as well as the original format. If the movie was good, the story was usually changed - not necessarily for the worse, but definitely not the same tone or message. If the movie was bad, well, often it was very different from the book as well (Will Smith SAVES TEH WORLD instead of dying philosophically), or sometimes it was a little too close to the source material, showing scenes that worked great in a book but which fall flat on the big screen. (Usually due to the POV shifts and internal monologues that novels are good at but movies struggle to convey.) What are your thoughts on turning books into film? Have you seen a movie based on a book that was as good a movie? Have you seen a book-based movie that was legendarily awful?
