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

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

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.

Well, Brief Encounter is certainly one of my top five favorites of all time. I looked at Brief Encounter very closely, to be honest.

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.

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.
