I think it's necessary to identify with anything - with any character you play, there's got to be something in common, so you can link up to that person, even if it's like one tiny thing. But it's equally fun to play somebody completely different, and trying to find what that thing is to make it.
People are surprised at how down-to-earth I am. I like to stay home on Friday nights and listen to 'The Art of Happiness' by the Dalai Lama.
