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.

I was brought up a Catholic, so I take no pleasure in guilt.

The one good thing is that I get a lot more good scripts coming through my letterbox. 'Vera Drake' raised my profile in one way, and then 'Harry Potter' in another.

I worked in rep for six years, then I came to London and to the National Theatre. What's better than that

Agents and producers have to get you into a box to accommodate their limited imaginations.

I don't feel the need for religion. But I went on a yoga retreat last year and I do believe slightly in the karma thing and just being good and true unto yourself. And I slightly believe that you can attract good and bad to you.

You can only do your best. That's all you can do. And if it isn't good enough, it isn't good enough.
