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.

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.

It's the sort of subject that always interests me: jealousy and the language of suspicion and guilt. I think it interests people.

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

Well, I think just the fact that you are making your first film is a huge step.

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

I've always been interested in films where you can identify with the actors. Where you can be in their shoes and therefore be more involved if they're people that you recognize.
