I certainly gained a lot by reading about Shanghai.

I should say, a piece of advice that was given to me very early on by the principle of RADA (Royal Academy of Dramatic Art) which is where I went. When he auditioned me, he said, "Your speech, monologue, is fine. It's good. Yeah, I think you have ability but you're making it happen. Don't make it happen, let it happen."

Actors use who they are to be someone else, but I would hate to ever think I'm playing myself. It's imagining being someone else that is the key motivating thing for me. So when people want to know about me, it makes me a bit unnerved.
