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

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.

Napoleon was one of the most complex personalities in history.He was ruthless, small in stature, a bully, vulnerable, unfaithful and I think he was the first person to shoot prisoners of war so that he had food for his own army. He was absolutely single-minded but he also obviously had charm. How else could a man like him have come back as he did and have the nation rise to a man!

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.

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.

A successful swindler has to be a great salesman even more than a great actor.

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.
