I did sit in cinemas as a kid looking at English and American movies thinking, "Wouldn't it be great if the characters were like real people?" And the worst thing is films are constantly advertising themselves, drawing attention to their style of things. But actually I make films that I think are extremely sophisticated and cinematic. But you don't want the audience thinking about the bloody film. You want them to think about what's going on, and believe in it. Be flies on the wall, you know?

I've walked out of films. But for every film I've ever walked out of, I've probably walked out of 500 plays.

I am very happy to be part of European and world cinema as a British filmmaker.

I'm developing the stuff all the time. There's a film in my head. I'm imagining a film.

It's important to be true to the events, but the most important thing is to get to the essence of the experience. Not to be bogged down in an academic way by a notion of the truth. First of all, the truth is an illusive and spurious concept.

What I do is to collaborate with each actor and work one-on-one to create a character. And that is a matter of huge complexity and is a combination of a great deal of discussion and a lot of practical work. It involves a lot of consideration for the real people out there, and all kinds of sources of real people. The result is the character. But I'm not supposed to talk about what it is we do, because it's nobody's business.

Very occasionally I hire an actor and get it wrong. The actor just doesn't trust the process or me as fully as I thought they would. In this case, you can be quite sure that if an actor is untrusting, it's got nothing to do with me or the process.
