If not me- who?, If not now- when?

People sometimes talk about me as being a brand, having a strategy and whatever else. I wish. Seriously. I wish I had it together enough to have a strategy. But it's so instinctual. It usually comes down to two things: the person I'm working with - the director is really important to me - and a line in a script.

I'm a real Londoner. We have very grey weather in London, and I think it encourages a very eclectic and crazy fashion sense. I mix high-street stuff with more high-end fashion and vintage.

I'm a feminist, but I think that romance has been taken away a bit for my generation. I think what people connect with in novels is this idea of an overpowering, encompassing love - and it being more important and special than anything and everything else.

It's very hard to describe your own style. And I'm young, so I'm still experimenting. But I think it's quite British and very much about individuality.

I have collections of quirky things from places I've been to, like a set of Russian dolls.

I can be 100 years old but I will always be proud to say I was in Harry Potter.
