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.

My parents have always been cool. They even became surrogates to friends of mine who didn't have such supportive parents.

I couldn't get any of the ingenue roles when younger because at 5 feet 9 inches with a deep voice I was always too... genue. My career has completely happened since I was 29.

As an actor, you're just taking temperature. I am anyway, all the time, and responding appropriately. I was again cast very last-minute for Rushmore and met Wes Anderson, this quite physically and socially awkward man who didn't really talk to me much, a precocious and intelligent young boy. And Bill Murray. And we were sort of left in this bizarre hotel together and taken to strange locations around Houston. That was quite an isolating experience.

The way I miss my daughter Esme is to worry about her. It is not a pleasurable longing. It contorts my body and scrambles my brain, makes me stop breathing, clench my jaw and my fists, it makes me frown, and makes me blind and deaf, in fact entirely without sensory perception.

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.

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.
