Nearly every taping or audition has to be in an American accent, so you don't have a choice; you just have to get good at it. I'm sure you can appreciate accents - it's like learning any skill, you have to work at it and work at it and it takes an awful lot of time, until it's muscle memory and you don't have to think about it anymore.
I think I got into acting because I kind of had not much else to do! I guess I was kind of looking for something challenging. I heard about the London Theater scene and it was very different from the upbringing that I had and it felt like a challenge. And the whole sort of London Theater schools, I was told that 6,000 apply and there are like 30 accepted to each one. I was like, "Yeah. Let's see if we can do that!
My first time acting for camera really was for Steven Spielberg in War Horse. I was trained in theater and I was actually working in theater at the time. I had a small role with the Royal Shakespeare Company, which is a huge prestigious theater company back in England. I honestly thought that was as good as it got.
I hate the word "method acting." It's just so silly. You hear people going, "Yeah I'm a method actor." I'm like, "So what happens if you're playing a period film or something? You're in the Second World War. And what happens when your mom calls you on your phone? Do you go, 'Oh! What is this strange talking brick device?'" No. It's stupid. But you do everything you can to get in that mindset.
I'm an expert at killing time on planes now. I do a lot of reading. My secret sort of nerdy side is I'm quite into history so I read a lot of history books. Now I write for a few things and I've had a few history things published, which is cool. I indulge my nerdy side and it's kind of as far away as you can get from the acting world so that's nice as well.
