I think good things come out of having tension with the people that you work with. You've got to be arguing in order to produce something interesting. If everyone's just agreeing with each other, you're not going to push the boundaries.

My mother was in the kind of late-sixties, early-seventies origins of female emancipation. And she was very much like, "You're not going to be defined by how you look. It's going to be about who you are and what you do."

I'm keen to have balance, as much as possible. I put every ounce of myself into my work, but also it's important that I don't miss every single wedding of my best friends. I couldn't do what I do without my friends and family.

There's such a sense of theatre in getting glammed up; it's like putting on a play or short film.

I've done quite a lot of improv work before, and I wanted to do this film ["The Invisible Woman"] because it felt like a different technique. We were very true to the lines, and there was something quite formal and almost theatrical about it.

I think personally it's not good for anyone - I don't think infidelity leads to happiness. It's painful for the person being cheated on, but also for the person who's cheating.

I like to keep pushing myself and trying things out. I get easily bored, so I need a challenge.
