I was born in Glasgow. But my family is pretty much from a little town called Paisley, famous for its cotton mills and paisley pattern.

When I start a movie, I already feel like I'm in it. I'm not a jobbing actor anymore; most of the films I do, I'm involved with development. Some, I've taken from scratch, and worked so heavily on the script, I'm embodying a lot of the character by the time I even get close to filming, because I've asked so many of the questions that I do. There is nothing better than being able to ask all the questions, do all the work. It's when you let it go that you fly.

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.

Funnily enough, when I originally went in for my screen test, that set was already built.

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

Lessons not learned in blood are soon forgotten.

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.
