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.

My grandma said - when I was really young and I'd sing along to the radio - why do you sing in an American accent? I guess it was because a lot of the music I was listening to had American vocalists.

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 think it's so much sexier to be understated. It's more intriguing to be sexy in a less obvious way.

The character is everything that I felt really strongly against - she's superficial, materialistic, vain, amoral. She's all of these things, and I realised that I really hated her. How do you play someone that you hate? But I found it really interesting and it gave me a whole new insight into what my job, or my role as an actress, could be.

Field hockey is my strongest sport, and if I lose a game, I take a long, hot bath and moan about it.

Feminism is not here to dictate to you. It’s not prescriptive, it’s not dogmatic. All we are here to do is give you a choice. If you want to run for President, you can. If you don’t, that’s wonderful, too. I’m lucky I was raised to believe that my opinion at the dinner table was valuable. My mum and I spoke as loudly as my brothers.
