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.

If you are prepared to make a fool of yourself for them then you usually get that back. I think that there are points where you become so close to an actor, you know them so well, almost as well or better than their spouse. You have to know them, warts and all.

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

I wanted to make a movie about the arbitrary nature of love.

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.

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