Ralph Fiennes was a big hero of mine acting-wise growing up and while I was training. I just find him so watchable. He was playing this very intimidating character when we worked together and it certainly felt like he was in character off set as well! He was very cool. Before a scene, he'd be like, "Come on. Let's improvise. Let's just do stuff." But Jesus Christ. He's Ralph Fiennes!

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!

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

The work my mum does, a lot of it is re-housing homeless people, that's a real job. I play make-believe and dressing up for a living!

My bedroom's like an armoury.

I had a great drama teacher, and he sort of made out drama school as this incredibly difficult thing to get into: 6,000 people apply every year, and some of the schools only have 12 places. It's a phenomenally difficult thing to get into. And that excited me - I wanted that challenge.

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.
