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.

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.

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 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.

It's an honour to have such a wonderful international cast on board for this world famous murder mystery. Writer Stewart Harcourt has created an exquisite script. His attention to detail is impeccable.

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.
