I can't really see how anybody could be particularly optimistic about the future in general because we are destroying the planet.

The good thing from my perspective is that nobody puts any pressure on me to say what it's going to be. The backers accept that they don't know what they are going to get.

Film-makers should remain true to their principles and never compromise, there is a real revival in the British film industry but there is a danger that we will become colonial servants of Hollywood. We need to maintain our own integrity.

Because of the way that I work with the actors and because a scene is not in this rigid and literal interpretation of something written, I can constantly change stuff, which means I can get a scene absolutely perfect, and then when we go to shoot it, the requirements of the shot mean it would be useful to extend the dialogue or take a line out or swap things around. So the camera doesn't serve the action. The action serves the camera. That's important. So it becomes more and more organic and integrated.

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.

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.

The whole thing about making films in an organic film on location is that it's not all about characters, relationships and themes, it's also about place and the poetry of place. It's about the spirit of what you find, the accidents of what you stumble across.
