I categorically resist this idea that films are supposed to be autobiographical and the only stories you tell are about your own life.
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'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.'
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 spent a little time in Germany as a schoolboy learning German, and it's a country I knew very well, spent a lot of time in. I knew the history very well. I've always wanted to do a piece of work about the post-war period, of one sort or another.
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.
