I'd love to do a cop film in America. That's a genre I absolutely adore.

I always say to anybody who's going over to America for the first time, 'Whatever you do, go and see a popular mainstream film with a big audience.' Because people shout out. You never get that in Britain. Everybody's so quiet, scared to laugh. It's like being in church.

I always think, when there's stuff that people don't like, I always say that if I have another success, I'll enjoy it more, but you don't really.

I trained in the theatre.

What you do is take the power [popularity] gives you - which is very temporary and minor but significant - and use it. The danger is that you use it on a vanity project that no one wants to watch.

I don't want people to sit there and objectively watch the film. I want them to experience it as something that's under their skin, so you try to make the films really tactile.

If I was American, I think I'd live in New York, because I like that East Coast mentality. There's nothing wrong with Hollywood. If you want to be a big time filmmaker, you should go to Hollywood.
