At first it was a bit strange and daunting to have to wear a mask, but afterwards I came to enjoy it. In warm conditions, though, it started to slip off my face. Other times they used this double-sided sticky tape, and I literally couldn't get it off my face. I would feel like I was ripping my face off and I had a lot of cuts and bruises because of it-huge red marks. People might think it was method acting.

Whenever I watched this movie ["How to Train Your Dragon"], I thought, "That's where I want to be. I want to be up in that sky. I want to be flying through the clouds and be living in that environment." So I think if I had a dragon, I would spend most of my time up in the air all over the place and taking in this beautiful planet.

I do get stressed at times, but I love what I do as an actor. This is the part that I don't like. I don't actually like talking about - I wish I could just go and get on with my job, because I love getting a script, breaking it down, working with other people, bonding with other people, fighting with other people, and out of those arguments, creating something that nobody expected and seeing it all come together. Telling a story, having an impact on people's lives, moving them and making them laugh.

Comedy is actually very hard. It's hard to choose those moments and know when you can really push it, and know when you should be bringing it back and making it more subtle, and knowing as time goes on, as you do take after take and the crowd around you stops laughing. Whenever you do comedy, you realize you're up against - you're performing next to people who you would think are so unbelievably good at it, that that's a bit of a pressure. But at the same time, it's just fun. It's fun to be able to let out that side of you.

My manager and my agents, they go over my contracts.

I'm very down-to-earth. I think I'm still 'street'.

I think the American justice system has a lot more issues than the European justice system, especially the Scottish justice system. We have a really nice mix of European codified law and the traditional English system of common law, which is what the American system is based on.
