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.

Somebody said that I'm a bit like a sponge, grabbing things here and there, soaking stuff up. [As a director] you have to be, really.

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.

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

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.

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

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