Directors are always changing things at the last minute. Actors will do a scene, and the director will say, ‘Okay, that was perfect, but this time, Bob, instead of saying “What’s for dinner?” you say, “Wait a minute! Benzene is actually a hydrocarbon!” And say it with a Norwegian accent. Also, we think maybe your character should have no arms.
I can't recall a story that played out exactly as I'd expected it to. That's one of the thrills of journalism - being surprised, and learning new stuff, but it also poses the biggest challenge to a writer's character.
With a novel, you have the reader with you a lot longer, and you owe him a lot more. Obviously you have to have a plot - I say "obviously," although I think a lot of fiction doesn't, and nothing seems to happen. But to me, there should be something that happens, and it should be at least vaguely plausible. And because the readers are going to be with these characters for a long time, you have to get to know them and like them and want to know what happens to them.
