My mum says that I was born 45, and I do remember at six thinking that I should be earning my own living.

I totally agree. I hate knowing too much when I'm going to the cinema and watching as a viewer. I don't want to know that the actor has just gone through a divorce. I don't want to know that the person is an alcoholic. It just gets in the way of my pleasure of watching the character on the screen.

All through my life what I've loved doing is watching movies. I love the escapism of film, I love stories. So it is incredible to be able to be in them as much as I am, to see them from the first stitch in a costume to the end product.

I love costume dramas, I love performing in them, because in a funny kind of way, you feel more free. You know about the period, you can read the books, you can see the paintings, but you've never actually going to know what it was like. You can kind of stretch those boundaries a bit.

Well, the thing about great fictional characters from literature, and the reason that they're constantly turned into characters in movies, is that they completely speak to what makes people human.

I would be extremely stupid if I said that my looks had absolutely nothing to do with what I do, it [moviemaking] is a visual medium. I'm perfectly aware of that, the face and the body help. Of course they do.

It's all about perfection, isn't it?
