It was as big as a Beatles concert, I guess. Friends was unbelievably popular in Britain, and it was incredibly exciting. I had never experienced anything quite like that before in my life. I was honored to be a part of that.

Usually the casting process is lengthy and humiliating, but in this instance, The Ghost Writer, it was just too easy. I was sitting in a rental car on an L.A. street and my cell phone rang, and it was Roman Polanski on the line. I couldn't really believe my luck. He said, "See you in Berlin." I sat staring at a palm tree, thinking how surreal that was.

I was lucky, because Ewan McGregor had already been shooting with Roman Polanski for about a month before I got role. And he did a faultless impersonation of what it was going to be like. So when direction happened, it was like, "Oh yeah. That's what Ewan said was going to happen." And so it was a little bit less debilitating than it might have been.

When Roman Polanski did give you a "Great, great, great!" you were just like, "Thank you, Lord, for this magical moment."

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.

I loved Rushmore. I loved the script. I mean, that is what drew me to it, just the actual piece of literature the script is. But I never thought in a million years that anyone would see it or respond to it. It was an absolute joy that it was so loved and continues to be. The same with The Sixth Sense. I thought, "No one's going to watch this. Bruce Willis hasn't got a gun. There's no shagging. Lovely story, sweet and profound about loss and death, but no one's going to watch this."

Roman Polanski actually said as much to me once. He had his head in his hands, and I said, "Roman, I've got to tell you, as an actor, seeing the director with his head in his hands... Look, I really want to do what you want me to do." And he went away and he came back, having obviously thought about what I said. And he said, "When my head is in my hands, I'm closing my eyes and trying to remember what I saw in my head, before any of the stuff."
