One that always comes up is “To Have or Have Not”. Since I haven’t read the book, I can’t comment, but Hemmingway considered it his worst, I believe, and challanged Howard Hawks to make a good movie of it. Which he did.
Rising Sun. I remember hearing that Michael Crichton was a tad upset at the casting of Snipes as Lieutenant Smith, saying that he’d never envisioned the character as black, but I think it improved the story.
