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.

When I was 16, I made some little 35mm documentaries about the poor in London. I went round Notting Hill, which was a real slum in the 1950s, shooting film.

I don't really want people to see me. I'm not into stardom.

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 think we have reached a level in society - with Helen Mirren playing The Queen - when we're not surprised any more. We don't mention names. Yes, it's obvious by inference. But we don't mention names and the film is not up to point fingers at Royalty.

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 seeing my characters big up there and I would have liked to have reached a different public in movies from my television public. There's still a part of me that wishes that my character range could be seen on the big screen. Rather, as Rod Steiger was, because he was a big influence on me - about becoming other people and not worrying about your own glory or self esteem but sacrificing yourself to become somebody else.
