Choosing the right mask helps you... We went through many masks. It was very particular leather that as soon as you smudged it, you had to get a new one. We went through about 55 masks.

Up in the north of Scotland, a lot of the villages are completely Viking names. A lot of Vikings came down and settled in Scotland and in Ireland. And a lot of them didn't, but they took plenty of us with them - mostly the chicks.

When I was 12, I was in Oliver! at a theater in Glasgow.

There's always advantages and disadvantages to doing any role. And there's a great sense of achievement, testosterone, fun, being able to live out your masculinity when you play an action role, or an action-adventure, or a real tough-guy role. Really, if you're doing a comedy, you can sit back and relax. And it's good to know that at the end of the day, you don't have to run off for another two hours and go to the gym, or go spend the rest of the night swordplaying with stunt guys. Then I think, "Oh my God, I love comedy.".

I don't know whether it's spiritual development or trying to learn the psychologically with being an actor, but I realise the more I get into it that this was something I was always supposed to do. That allowed me to sit easiser in the life I was living. But that doesn't mean to say you just stroll through it. It takes work and the work is not always about acting. It's sometimes about how you deal with the ups and downs of hope, of expectation.

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.
