So, if I ever played Napoleon it would be with an Italian accent. He was an outsider, which also interests me.

I think its very dangerous, the idea of celebrity - you have to be constantly controversial to maintain the status of celebrity. Reality TV is the death of entertainment - its just mindless TV but popular because of its voyeuristic nature, and people are very voyeuristic.

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'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.

I love music, especially classical like Verdi; it's a great way to relax.

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.
