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.

What I've realized is that all of these people are so successful because they love what they do and they work exceptionally hard. No one gets successful in this business by fluke really. There are probably a couple of exceptions but most people just work so hard. They are working every day and they are doing their prep.

I've been very reluctant on the Twitter front. But I do Instagram now, so I'm slowly coming around. I'm quite a private person, so much of what I do for my job means that I have to be quite public so I'm just nervous about everything being public. I might turn around. Three years ago, I was against all social media but I actually really enjoy Instagram now. Who knows? I never say never!

I actually collect old First and Second World War memorabilia.

I think most actors will tell you the same thing; when you're not working you put 100 percent into every audition.

You can be the best actor in the world, but if you don't have that one lucky moment, it kind of doesn't matter. There are a lot of amazing actors who will never get the chance to prove themselves because they won't have that one lucky moment.

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.
