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.
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.
I think I've grown up in an era where character acting on film has become less desirable for the producers and directors and therefore the audience. They have got used to the people that those actors really are.
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.
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.
The great exception to that, of course, is Johnny Depp, who is absolutely the ultimate character actor. Johnny Depp is the future of the character actor and thanks to his success maybe we will see the return of an era when my sort of actor is back in vogue. It's not in vogue for me to be in Hollywood movies as lots of different people.
