I'm not really a director for hire. You read these scripts and go, 'This is a really great script, but Paul Greengrass would make this so much better than me.' I usually say, 'I know who would be good for this. It's not me.

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.

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.

England is strictly class-based. What's surprising is how many films are still made with a load of people in silly frocks running around gardens and talking in middle-class accents.

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.

I love changing. I hate it when people try to box me in to a relationship or in a work context. Any situation where I feel boxed in freaks me out. And I feel the need to reinvent myself or I'll get bored.

I always say, 'I really need to take a break.' It's three days in and I'm getting pretty bored.
