My problem is, whether it's for emotion or for the talents that a character has to have in a role, I find it very difficult to not take on a challenge. I need to say, "Okay, enough, take the easy road." But the easy road for me is not - it might just come out coincidentally. I wouldn't ever choose a movie because it's easy. I might choose a movie because I feel like being funny, or I feel like being able to do something that is perhaps dramatic, but to a lesser degree. Because I like switching it up, basically, not because I would take the easier road.

Be the hero of your own life story.

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.

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

Theres 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.

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.

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.
