I'd love to get fat on camera. Wouldn't that be great? I'll tell you what's almost as hard though, getting bulked up, getting that big. Here we are in LA and you see guys walking down the street and everyone looks like Arnold Schwarzenegger. That's really quite grim, if you haven't done it before.

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.

Every time I get a role I think, 'I've actually fooled them again, I can't believe they keep falling for this!

I wouldn't want to see any animal in pain, no matter what.

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'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!
