The British vice is overthinking before we speak, which is really annoying. I love the way that, in America, people are more straightforward.

I've done a lot of very low-budget indie films, so it was just really exciting and fun to be doing a film where there's a lot more time and these huge, vast sets. I was like a kid in a playground. It was amazing!

I really enjoyed it - being involved in watching rushes and playback [in "The Invisible Woman"]. Ralph [Fiennes] was very open to my input, I think knowing that he couldn't always be there 100 percent, that he had dual aims with directing and acting.

The more you work, the more people can see that you're something different from what's come before.

"The Theory of Everything" is an extraordinary story because [Jane Hawing] was incredibly religious and [Stephen Hawking] was an atheist, so you have this conflict both on a domestic level between a couple in a difficult situation but also this bigger conflict of science versus religion, so it's a really fascinating project.

I love not having to rely on anyone.

I'm small. I'm petite. But I'm a bit of a fighter inside.
