I think one of the London Film Festival strengths is that it's set in London but it's not about London. It's about the diversity of this city and it's about world cinema. And that's what London is - London is a place where its identity is always in a state of flux. So, this festival celebrates the way in which it is always changing. That's why London is a fascinating place and that's why the film festival is a fascinating film festival.

As a working-class actor, leaving school with no qualifications, being a printer and then becoming an actor and then working with people who to a certain extent had had a leg up. I never had that advantage. It's less an artistic need to express myself and more a need to prove myself.

When I think of character actors, I think of Spencer Tracy; I think of Gene Hackman, Robert Duvall. When I was a young lad watching films, my eyes were on them - watching 'On the Waterfront,' my eyes are on Rod Steiger and Karl Malden, not on Brando.

I have friends who are leading men, and they're only ever allowed to play leading men of a certain type. But as a character actor, there's a wider variety of projects available. On the big Hollywood films, all they care about is having their lead in place, so it's actually easier for someone like me to slip in. And I'm happy to do so.

There's no great mystery to acting. It's a very simple thing to do but you have to work hard at it. It's about asking questions and using your imagination.

I've got four kids to feed and a wife to provide for. It's a worry but a great responsibility as well and one I relish.

I'm the guy who plays human beings. I understand why the characters are doing what they're doing. When you play a villain, you don't play a villain: you play a human being doing what he thinks he needs to do to get what he wants.
