That was a bizarre and unlikely event, which has misled a generation of drama students from my old drama school that dreams really do come true. I was an unemployed actor. I had been an actor for about eight years, and had worked in theater, and done a tiny bit of TV, and somehow an audition video of mine ended up on Kevin Costner's television screen, and he rang me up and invited me to fly first-class to Hollywood and be in his movie The Postman.

I love the ups and downs and the eccentricities of my career. The worst movies have produced some of the best friendships.

Ewan McGregor and I said this to each other after we saw The Ghost Writer. Every time Roman Polanski did a "No, no, no!," he was right. It was really as if a sculptor was asked to sculpt the embodiment of despair - that was the attitude he would strike. But as with every sort of inspiring teacher you ever had who was strict and scary, when you get it right, the sun comes out, and it's worth it.

I'm 5'9" and have the body of an English person that doesn't know how to diet.

My skin may have wrinkles but it's because I'm smiling so much. That might sound like some terrible American greetings card, but I feel it's immoral for me to castigate my body for getting older, when it does everything I ask of it.

I have many debates now with friends on the changes, and the continuing confusion over bringing up your children, instilling values, letting them make the right choices.

My analysis of the situation was that Roman Polanski wasn't trying to break us down or get a performance out of us by destroying us. He was absolutely, very simply, trying to recreate this clear picture in his head. And the pictures he creates are absolutely perfect, and they are exactly what he saw in his head.
