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.

I was approached to do something for seven years, and it was a quality project. I did seriously think about it, but I didn't want to be away for six months of the year. I've never done the L.A. thing where you go and have loads of meetings; I can't say to my wife, 'I'm going to wait by a pool for six months.'

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.

My idea is just to do something different each time; the next thing I do has to be completely different to the thing I've done before - that's what I try and do, because you know, I'm an actor, not a film star.

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.

Mike Leigh taught me about making choices - as an actor, you choose between being honest and clever, and with Mike, it's always about being honest. I learned how to behave on a film set from Jim Broadbent. He was a great example of someone with a fantastic career who kept his feet on the ground.

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.
