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.

With a face like mine, I'm never going to play a character who conquers the universe, I'm going to play characters who are subject to forces bearing down on them. My career's based on how we are rather than how we wish we were - they get the good-looking boys in for that kind of role.

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.

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.

I'm used to being in front of camera and knowing what to think. But if you're asking me to be me, I get very self-conscious. My job isn't to be me. Being an actor, people think you can do a eulogy at a funeral, a speech at a wedding. I find all that very nerve-racking.

The trick to acting is not to show off; it's to think the thoughts of the character. I was lucky because when I started acting, it was doing jobs above pubs. I learned to act in anonymity, so by the time people saw me, I knew what I was doing. I was crap for years, but no one saw me being crap. It's a trade you learn.
