I'm a big supporter of Joe Johnston and I think that 'Captain America' is going to be really fun and I gather that the story is really interesting. It just wasn't what I wanted to do next, to be honest.

A lot of period dramas can appear quite arch to most people, stuffy.

If you're very open to watching the world go by, with people's different tics, you absorb it all without realizing it and find ways to put something into your character. I'm not sure I'm always aware I'm mimicking someone.

I'm not much of a crier but it is mildly soul-destroying and exposing to do something physical that you are terrible at in front of other people.

If you're in America a lot, it's easy to get into playing American. All of it, the sounds, the energies, all very different. But it's really hard to do the accent. I tend to try and stay in it all day, which is the only way I can manage it.

When I read a script, I'll have a very visceral gut reaction to what does this mean to me? How does she feel in my skin? Could I play this role?

It's always better just to do work that you're really proud of and work that you enjoy because really all you have are the choices you make and that's it and who knows after that. I think that's what I love in acting.
