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 am very traditional as a man. I am not modern and never have been. I think I was born 50 years of age and out of my time.

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.

In The Godfather, for instance, they say they won't deal drugs because they have a code of behaviour. He is the last remnants of that. So playing someone like that, who is also in pain with his kidney stone, means you're beginning to find a dimension of the guy who is king and all show and the private guy who is in pain.

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.
