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

The really successful work in England tends to be working-class writers telling working-class stories. The film industry has been slow to wake up to that, for a variety of reasons. It still shocks me how few films are written or made in England about working-class life, given that those are the people who go to movies.

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.

You go through a process of refinement and getting rid of the excesses of your early youth in terms of your excitement about what theatre can do.

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.

I'm a theatre person, that's who I am. I'm happy to make sojourns into the world of movies but I'm basically a theatre director that potters off and does a couple of movies.

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.
