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.'
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 get a lot of people saying to me, 'Oh, you're the actor who plays the nutters,' and I'm not. 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.
