The excruciating moments of drama are when people are allowed to show or say what they feel.

I'm a mixture of Anglo-Saxon, a bit of Spanish and one-eighth American. I've often wondered if I have an Asiatic ancestor from the East as well because I have deep-set eyes. Make-up artists are constantly trying to shade my eyelids, and I have to point out that I don't have any!

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.

The trouble with audition process is, when you're an unemployed actor, it's the only time you get to act, and it can be quite fun. If you feel in control of the material and you feel that the people are pleased to see you and are excited by you auditioning for them, it can be a really rewarding process. But it can also be a very humiliating process.

I don't tend to spend the whole day in the personality of the person I'm playing.

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.
