I don't really want people to see me. I'm not into stardom.

I'm 64 years old, and I've been acting now for 42 years. Only recently have I thought to myself, 'Hmmm, it may be interesting to start directing.'

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.

Although I'm a very emotional man, I just can't have blind faith, I have to find out for myself.

When I was 16, I made some little 35mm documentaries about the poor in London. I went round Notting Hill, which was a real slum in the 1950s, shooting film.

I was a typical teen growing up in the 1960s, when everybody was into gurus and meditation.
