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!

Each year we go to the Cannes film festival and I tend to have all my friends pile in the back of my car and we'll drive from London. The poor production company think they're only putting me up and suddenly they've got eight people sleeping on my hotel room floor.

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 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'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.

Determination becomes obsession and then it becomes all that matters.

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.
