I used to collect knick-knacks, like wizards, trolls and little buddhas, and arrange them like precious things on a shelf.

I don’t think that actors are necessarily any more uncomfortable in their skin than anyone else. I suppose I feel more comfortable in my skin now, but you’re always playing a character, aren’t you? You tell different versions of yourself to different people and vice versa. Here, or in the photo shoot or wherever, it’s a representation of you. It’s not you-you. That’s how you get through it.

When you have a character to work with, you carry them around in a strange way - they make you look at the world in a different way.

I've been out to LA a couple of times but, over there, the Grenouille in me always comes to the surface. I feel completely terrified, totally flummoxed, like I don't understand what the hell is going on. I've no desire at all to go back there.

The criminal justice system, like any system designed by human beings, clearly has its flaws.

Dustin Hoffman takes such pleasure in what he does and there's nothing tense about him. He exudes joy and passion for what he's doing and that infects everyone. It certainly put me at ease coming to work with him every day. I felt his confidence and freedom rubbed off. He doesn't censor himself or stop an idea because he thinks it might be wrong.

For me, it's important to keep a level of anonymity.
