I love test screenings. Some directors don't, I know. But I love it. I think it's because I come from the theatre and in the theatre, previews are where you really have to listen to the audience and really feel how they're responding. I found our test screenings incredibly useful.

Every now and then I have to teach directing. The thing about the theatre is that the most important thing you can do as a director is to make sure that everybody is in the same world - you have to create the world and make sure everyone buys into it.

I categorically resist this idea that films are supposed to be autobiographical and the only stories you tell are about your own life.

I never want to make a film. I don't wake up in the morning going, 'Ooh, I'd really love to be on set making a film today'. I'm aware that other contemporary film directors perceive film-making as what they do, as what they have to do. But I would hope that I am more catholic in my tastes.

When I got married, my mother was very surprised. She said: What on earth is going on? I thought you were gay?

In issues of recent ethnic wars and genocides - particularly if you look at Darfur - one of the most remarkable things is our inability to act, still, despite the years of analyzing and re-analyzing what it does to subsequent generations. We still find a massive inability to step in and step up to the plate, when genocide is happening as we speak.

There are a few writers that one has a relationship with that means, basically, you do whatever they say. One is Caryl Churchill, and the other is David Hare.
