My parents are both lawyers, and my father always said his best cases have been returns, cases that come into his office from another lawyer. So he said, "Never be ashamed to take a return." All my best roles have happened because someone else dropped out at the last minute, and God bless those actresses for their queeny fits, their sprained ankles, their better job turning up, because that's how I've got my best work.

For me, selfishly, The Postman didn't kill my career. It meant I didn't shoot straight and painfully into the limelight, but Rushmore came out of it. No one would have known where I was to cast me in Rushmore had I not been in The Postman. Because they shared a producer. Nor would I have been in The Sixth Sense. Nor would I be speaking to you now if Kevin Costner hadn't cast me in The Postman.

My very first friend was my stand-in, who's a very dear friend to this day, and she kind of saved my ass. She told me where to stand and where the camera was and where to look. I thought, "If I don't enjoy this, then there's absolutely no point in being an actor."

I think it's quite lucky that I lead this lifestyle, and in fact, my career's only gotten better as I've looked older, because it ages you, the uncertainty.

As I was getting into the helicopter, a slightly nervous actor said to me, "Whatever you do, don't say to the helicopter pilot, 'Show me what this baby can do.'" So I of course, got into it and said, "Show me what this baby can do." And we just had this insane helicopter ride. It's the sort of thing you only get to do on movie sets. I'm so lucky to have done it and have that chance.

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.

Ewan McGregor is a very genial and entertaining man, and Pierce Brosnan is possibly the nicest man in the world. Actually, it was quite a genial set The Ghost Writer, but the weather and the colors and the actual surroundings were oppressive. But it was a created atmosphere. What was so striking is that Roman Polanski had his crew from The Pianist, and we were shooting in Berlin, so there were German and Polish and French people, and I was just sort of enjoying being in this mix of people, all kind of rubbing along together. That felt good.
