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.

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.

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

Well, there are three different processes of making a film, of course. They're sort of re-written three times. You write it to start with, and then you shoot it and you re-write it while shooting and you sort of re-write it as you edit.

Is it appropriate still for a German to have a gun? I only use that as an example of a country that's still deeply involved and engaged in the conversations about how to come to terms with the past. Certainly for that country, it's not forgotten.

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.
