I always thought, while young, that Black Sunday and Jaws were pretty close to the books. Then, after I saw both The Manchurian Candidate and The Caine Mutiny and then read the books, I understood the difference.

Also, for such a celebrated author, Capote was a self-hating shit who drank himself to death. Plus, he really wasn't that good of a writer. Gore Vidal was in that same vein. He wanted Marylyn Monroe to play Holly, but Arthur Miller told her no, the material was beneath her.
