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.

I think you get better at staring into space. Especially living in the South of France.

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

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

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