Acting has always existed alongside my normal life. It's been a case of learning on the job. I've worked in so many styles, with so many people, so I've picked bits up from everyone and everything.

My mother was in advertising and worked incredibly hard when she was bringing us up. She was a working mother and a working single parent. That instills in you a sense of determination.

I was a tomboy running around in the garden. I used to play on a local cricket team. I grew up with all boy cousins, for the most part, and my brother. 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."

The British vice is overthinking before we speak, which is really annoying. I love the way that, in America, people are more straightforward. The American vice would be sometimes speaking too loudly. You can always hear American people on the trains!

I guess I'm a bit of a romantic.

It was amazing how much rehearsal helped with the performance - it was almost a theatrical approach to filmmaking.

I've never taken a role where I don't like a person on the page. Sometimes there are changes that need to be made.
