Novelist William Kennedy, author of Ironweed, once made the following point during an interview about his work.
He received a no on one of his novels. As he noted, The usual negative attitude toward anything that you present to folks in Hollywood. They say no all the time; very rarely do they say yes. They’re in the business of saying no; they’re in the business of not making movies. I thought we could have a good adventure movie, but it didn’t happen.
