I don't think I've got enough energy to be competitive! Most of my energy is just devoted to me being nervous and trying to deal with the situation.

In fact, when I met Kit Harington first, he was pretty much feeling how I'm feeling today - at a photo shoot and you've had no sleep. He was just a really nice, English, down-to-earth guy. No pretense, nothing.

With acting, I've got a character to inhabit. You've got to think about your intentions and your directions. In modeling, even though there's an act to it, a good model is a good model. For me it's uncomfortable territory. You start to feel quite insecure about yourself. There's nothing between you and the camera, and it's just you.

Acting advice is a bit like your parents teaching you how to drive a car. You know they're right, but you still kind of want them to shut up a bit.

I mean, it's fine when you're a kid and someone runs into the playground and goes, 'I've got this great game of pretend,' and you play... As an actor, getting to play, getting to use your imagination and be childish - it is weird but it's wonderful.

I've got my dad's height and smoking habit. But I think I've got my mum's looks and sensibilities.

I think it's quite good to have an amount of unavailability.
