The only mistake guys can make is to try too hard with their appearance. There's something very unmanly about it.

I collect old first and second World War artifacts and things. I'm a little secret history nerd. I've been lucky enough to do quite a few war movies too so I've taken little things off each film.

I spend a lot of time in L.A., and I think it would probably be easier if I lived there work wise, but there's no city like London, there is so much going on. I can jump on the Tube and be anywhere in 20 minutes, and all my friends and family are here and I'm not prepared to give that up.

People expect your life to change completely. The main difference is I can get work now. I can do my hobby as a job. It's great. It's a privilege. But in terms of the rest of the stuff, I still got all the same group of friends I always had. I don't do anything different. We still go to the same dirty bars and do the same things. So nothing really changes.

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'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.

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.
