I was watching Monster's Ball, which is a fabulous movie. It's just a little gem: beautifully shot, and shot in a way I never would have done. It made me feel very old, really, because it wasn't eccentric for its own sake, it was just very original.

What I think is interesting is that the more you do, you have to invent a book of rules of what you can do and what you can't do. And the very real danger is that if your book of rules becomes a book of cliches.

Always, with any movie that I do, I have a book of ideas that I've heard, or seen, or whatever, and I always try to incorporate it in the film.

I was speaking to Ridley Scott the other day and he makes a film every 18 months. He's amazing really.

Obviously, in dealing with a relationship, sexuality has to be involved, and jealousy and emotions like that. And I don't know, I've always been intrigued by those emotions.

The challenge, really, on any new film is to try to avoid that and achieve a few moments that aren't cliche.

The danger is that if you have a bunch of ideas that you forget to use.
