When I was 16, I played Macbeth at school and my English teacher said, 'I think you may have acting talent. Try to get into the National Youth Theatre of Great Britain and see where you get.' I wouldn't have thought of that at all. I wanted to be a surgeon, but I wasn't a clever man.

I was a typical teen growing up in the 1960s, when everybody was into gurus and meditation.

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.

I'm really not interested in showing me or playing me. My gift as an actor, given to me, is to be able to become other people.
