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.

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 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 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.

There are clues in the script... he will say "I think drugs are immoral"'... but the guy who says that kills, tortures, pimps and has whores working for him. There is this strange morality going on, which is rather like the Mafia.

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.
