One of the great joys of my job is that you spend a huge amount of time investigating different areas of literature.
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.'
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.
