I think Michael Caine is a perfectly good actor but it's obvious he's not going to be in one of my films.

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.

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 try and create for the audience something that relates to real-life experience.

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.

Some deeply untrusting actors - the kind that need to know exactly what's what and are completely insecure - might be quite good within the parameters of a certain sort of acting.

I make films because I am endlessly fascinated by people. I'm fascinated immediately to know about the lives that are going on around me. That is what drives me. And that is because everybody matters, everybody is there to be cared about, everybody is interesting and everybody is the potential central character in a story. Judging people is not acceptable.
