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 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.

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

I would love to do something for TV... I wanna do 'Kavalier & Clay' on HBO as an eight-parter. It'll be so much better as a series, honestly.

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.

Actually, to be honest, this is a useful time to not be knowing what I'll be doing in 2013 or 2014, because really, for the last however many years, I've known what I've been doing for years and years ahead. You get into a cycle of non-reflection, and that gets a bit scary.

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.
