We're in a world that celebrates things: success, beauty, money. And I reckon that's really about 4 per cent of the world. The rest of us are just getting on with it.

To me, it's really not about how I look - it's about who I can be. It is my job to bring the character to life and my duty to fit into the jigsaw in that story.

At the time of Woodstock, I was just 13, but I used to see these exotic hippy creatures and I did look on with envy. How could you not? In an ideal world, I would have loved to have been a hippy - but I might have been a bit strait-laced. It was my fantasy.

A lot of film stars are just playing themselves in different frocks.

Fortunately my career has never been about how I look, it's about how I can be.

I don't think it's that I don't like Sondheim. It's that I find it really... I don't know how to describe it. Doing it is the most extraordinary thing. Because it's like Shakespeare times 100 with singing. It's that satisfying - and that demanding.
