I was training to be a lawyer... I was president of the law society at Glasgow University, and my bass guitarist was my secretary of my law society; the lead guitarist and writer worked at the law firm that I worked.

Generally I don't like doing remakes, but I think that's more in the cynical world of Hollywood where normally remakes are purely for commercial reasons.

One thing I've learned as an actor as well as a producer is to trust my own instinct. When I first started acting I would sometimes have ideas about certain things, whether it's a scene, or a character or certain dialogue, that wouldn't be followed. I was never in a position to have the power to press the matter. Sometimes it wasn't even about my character. But I'd watch the movie afterwards and think I was right.

[How to train your dragon] is beautiful to look at and, again, those values that it contains about relationships, friendships, and bonding in the face of ignorance.

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.

It's so incredible when you meet somebody who comes up and passionately tells you how much they liked you in a movie, or how much they liked thamovie. That's a great thing, because I know what I get out of watching a great movie. So I love what I do, but it's more - I don't think there'd be anybody who would tell you that, even if it's something they love doing, they don't get stressed out by it. I'm a very intense person, so I go very intensely and passionately into what I do.

I had to go and sing with the musical director of the film, Simon Lee, who is just incredible, and it went great. I sang with him about five things, things we'd worked on. And then I went to sing for Andrew Lloyd Weber.
