When you make something, if you are a painter or a writer, a degree, or a sculptor or whatever or a musician, a degree of energy is required to make it, and I'm not sure that it is always aggressive, but when you have a great deal of energy it can appear to be more aggressive than it is. In fact, I mean you can talk about a waterfall being aggressive, but in fact it is just a very powerful forward movement of energy, and although I think sometimes my engine house is a kind of anger.

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 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.

Theatre artists are essentially sort of charlatans and thieves, I mean that's the tradition that we come from, so I have absolutely no, I make no bones about the fact that I steal from here and I take from there, and we all do it, that's perfectly all right, that's the nothing, there's nothing new in the world, there's nothing actually new in the way that you do something, but the point is is how do you take something and use it to articulate what is essentially a core of any given theatrical production.

I think it was a desire to be able to find my own voice. I think that was the big urge within me.

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.
