If you want to run for Prime Minister, you can. If you don't, that's wonderful, too. Shave your armpits, don't shave them, wear flats one day, heels the next. These things are so irrelevant and surface to what it is all really about, and I wish people wouldn't get caught up in that. We want to empower women to do exactly what they want, to be true to themselves, to have the opportunities to develop.

We want to end gender inequality, and to do this, we need everyone involved...We want to try to galvanize as many men and boys as possible to be advocates for change and we don't just want to talk about it. We want to try and make sure that it's tangible.

I decided I was a feminist and this seemed uncomplicated to me. But my recent research has shown me that feminism has become an unpopular word. Apparently I am among the ranks of women whose expressions are seen as too strong, too aggressive, isolating, anti-men and, unattractive.

It's funny when I look at my life; my primary school was two-thirds male to one-third female. So I started my life that way. I have two brothers. And when I did Harry Potter, the ratio was more often than not, at the very least, one-third female, two-thirds male.

But it's a journey and the sad thing is you only learn from experience, so as much as someone can tell you things, you have to go out there and make your own mistakes in order to learn.

The difficulty for me is that I'm interested in so many different things. I could never really imagine myself doing one thing, and I'm pretty sure that I'll end up doing four or five different things.

I like Valentino a lot - they never use actresses in their campaigns.
