Every time I make a film, I feel it gives me the chance to learn something new.

I've been wanting for some time to find a way of stylizing cinema and trying to get closer to the emotional story I was telling and get rid of all the bumph that goes with it and allow the audience a more participatory experience. It was an attempt to do all of those things and to express the idea that all these people were just performing roles in their lives.

There's good art and there's bad art. A lot of action films are bad art, but Paul Greengrass showed us with the Bourne films that it's possible to make an action film with a political, social conscience.

I see the job of directing as being one of creating the right atmosphere, creating an environment where people can realize their full potential.

I went to comprehensive school in North London and left without any qualifications [diploma]. And I was doing bits of acting and improv in a drama club in the evenings. Then I discovered you didn't need qualifications to go to art school, you just needed a body of work.

I like the idea of doing something outside my comfort zone.

An artist needs to live to create, and to live means to suffer.
