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 am, in fact, Superman. Every morning I wake up and go into a telephone booth and change my costume, and then go to work.

As soon as I know how to do something, I usually get bored with it.

There has been one defining production for me in each decade.

The great fun of doing new plays is that people have no idea what's going to happen next. That goes quite soon, as people start talking about it, and the only way you can keep hold of that is genuinely to keep changing it.

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 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.
