I've learned, having been on a lot of sets, the good news is that by definition you are surrounded by experts. They get fired if they're not - unlike in the theatre!
Older people say, 'Oh I loved you in 'Sense and Sensibility,'' and that's the only film they want to talk about. Equally, there are people who only want to talk about 'Galaxy Quest.' And there's a whole bunch of teenagers who only want to talk about 'Dogma.'
I have every sympathy for writers. It's a mystery to me what they do. I can edit. I can cross out and say, 'I'm not saying that' or, 'How about we move this to here? Wouldn't that make that bit of the story better?' But where any of it comes from is beyond me. I will never write a play or a novel.
I think the thing about film is, as it gets proved by a lot of young filmmakers now, that the medium will just go on reinventing itself, and so you just hope to be a part of that and not a part of some kind of endless regurgitation or 'Here I am doing what you know I do' kind of thing.
