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'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.

If I wanted to work financially, I would have made a series of different choices. I do get offered lots of movies which you could make a lot of money out of. And I always say, 'Why would I do that, when someone else could do it much better than me? Why would I want to do an action picture? Why?

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

The truth of the matter is, every film is imperfect. It's the nature of the beast. One of the things that people ask me all the time is, what's the difference between theater and film, and one of the biggest differences is, in the theater you always get another go.

The really successful work in England tends to be working-class writers telling working-class stories. The film industry has been slow to wake up to that, for a variety of reasons. It still shocks me how few films are written or made in England about working-class life, given that those are the people who go to movies.

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.
