In the first place, I'm pretty thorough about whom I choose. I instinctively look for the kind of actor who is going to be trusting. There are all kinds of insecure people out there called actors.

I discover what my film is by embarking on the journey of making it.

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.

I grew up looking at... going to the movies a lot, as much as they'd let you. I grew up in Manchester in the north of England in the '40s and '50s. I saw a lot of movies. They were all Hollywood and British movies. I didn't see a film that wasn't in English until I was 17 when I went to London to be a student.

If I'm ever working on a set and anyone talks about a master shot, I say there is no master shot. Before I even went to film school, I learned about movies by being in a British feature film, where everything was shot master shot, mid-shot, close-up. But I reject the idea of a master shot. You don't shoot everything mechanically; you find imaginative ways that serve the action.

My work requires acting at its most committed - it demands actors of enormous resilience, but also intelligence and wit. It doesn't work for narcissistic or selfish actors.

I mean, artistic processes are all about making choices all the time, and the very act of making a choice is the distilling down and the getting to the core of what it is that you care about and what you want to say, really.
