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.

At school, I decided I wanted to be a director and then I went out and spent the rest of my adult life trying to be a director. It was really clear to me. So in that sense I was very lucky.

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.

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.

I think it's absolutely fascinating that in Berlin the parliament can discuss actively the role of their soldiers in Afghanistan because is it still possible, literally, for a German soldier to take up arms.

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.

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.
