If you're playing someone who has lived, there's the risk of imitation, or whether you focus on the essence of who that character was as opposed to physical mannerisms. So, you have to figure out what it is ultimately that this particular adaptation of the story, whether it's fiction or not, is trying to say.

I read a lot of heavy literature when I'm on set, so on holiday I want to indulge in something light-hearted.

Documenting trips makes them that much richer. I stick in train tickets and business cards from restaurants. It makes the whole experience poetic, describing the sights, smells and sounds around me. It means I can relive the holiday years later.

Although I grew up in London, I spent summers in Missouri, where my dad lived. It's quite a liberal town, Kansas City. You'd be surprised.

I'm deeply ambitious and I always have been.

The main reason I did 'Captain America' was because I wanted to get out of my own head and stop taking my work so seriously.

I like characters who have faults. I'm drawn to darker people.
