I guess maybe I was hired to play in the Doll House because of my dinner scene in The Sixth Sense, which has been scrutinized a thousand times as to whether you know Bruce Willis is dead, or whether I'm talking to myself. I think that maybe if that could be my forte, to do a scene and be able to say it could be read this way or that way.

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 am the worst judge of how a movie is going to do. I always have great and ambitious hopes, but none of them see the light of day.

My parents taught me everything and set me up for life. I owe to them all the things I'm passionate about: music, art, the people I love, my career and family life, the fact that I have children and the way that I raise them.

I wanted to play a TV detective because it's a rite of passage; I wanted to experience every area of acting. I haven't done comedy or as much Shakespeare as I had intended.

My agents were like "Come to L.A., we've got meetings for you." I was like "No, I'm doing this now." Then my father became very ill back in England, and I didn't want to be away. I went back to England and did a bunch of crazy indie movies, all of which I loved with a passion, and none of which did any business.

Carey Mulligan is completely self-possessed. She knows what she's doing, and again, quite like the big-hitters I was talking about, my job was just to feel and reflect back the amazing performance coming my way. If anything, I was slightly pathetically flying in her tailwind. She's an extraordinary actress.
