I had a teacher in Paris, who said that if an actor forgot what it's like to play as a child he shouldn't be an actor. I've always loved being with children. It's marvellous to see the fresh ways they see the world. Watching them look at a tree or a river helps you to understand something that's very important.

One of the things he liked about playwriting as to any other kind of writing is that a playwright is a w-r-i-g-h-t, not a w-r-i-t-e; in other words, that a playwright is more of a craftsman than an artist of the big novel.

Normally when people ask me what I do I say I'm an actor, and that's what I always wanted to be and that's the way I approach work even when I'm directing it.

The more they uncover the more mystery appears to be there.

People expect the math to be simplified, but I want to surprise them right from the start. When the brain gets lost, it doesn't stop working. It tries to makes sense of things. It begins to speculate and guess, and that's when things open up. That's exciting.

I mean I'm talking about playing games, about imagining other people, and it's part of the way that it helps you actually see the world.
