I became fascinated by the fact that people write to give away rather than write to be read. It's the difference between playwrights and novelists.

Deep inside, I am desperate to do comedy.

I'm never bored, never ever bored. If I've got a day off I'll sit in a cafe and watch and observe. I'm a great observer.

My fun as an actor and my task as an actor is to transform myself to become other people. I enjoy becoming characters but I don't enjoy becoming caricatures. The research I do is only necessary in so far as we move into other dimensions.

When I was 18 and not sure whether I wanted to be an actor, I realised that a playwright has no voice without an actor. That's my reason for acting: to get that character as right as possible for my writer. And I have never changed my philosophy.

As I say, there's something that scares the hell out of me but it really makes me work hard in losing myself. I'm not really interested in me as an actor or being a personality player, or a Hollywood star. What's given to me is to become different people and to find the truth of that. That is really what I do.

I love playing real people. It's a huge challenge and responsibility which I take on board and which I relish. It also scares me to death. Give me a totally fictional character and I don't have the same sort of responsibility. If, though, I play Sigmund Freud or Robert Maxwell or whoever then there is a responsibility.
