My job apart from anything else is to build an ensemble composed of actors who all come from a secure place so that they can all work together to make the film.

When I was young I used to sit in the cinema thinking wouldn't it be great if you could have a film in which the characters were like real people instead of being like actors.

For me the journey of making a film is a journey of discovery as to what that film is. I mean what I do is what other artists do, painters, novelists, people that make music, poets, sculptors, you name it. It's about starting out and working with the material and discovering through making, working with the material the artifact.

When it comes to thinking about how a character talks, there are literary and language considerations. For actors to be able to differentiate between themselves and the characters they are playing while at the same time remain in character and spontaneous requires a sophisticated combination of skills and spirit.

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.

A lot of the reasons that I'm resistant to making films in the U.S. have nothing to do with not doing a film in Hollywood, but rather to do with what I'm committed to working on in the U.K. I feel very committed to the British film industry and infrastructure.

The reason my films work is because every actor on set is very secure. They're able to fly.
