The one thing that makes 'Torchwood' work so brilliantly and makes it a little bit above the rest of all other sci-fi dramas out there is that we have a sense of humour.

Honestly, the world can be a dark enough place. Light it up.

I'm not one of those actors who likes to analyze things too much, so I trust what the writers are doing with the characters, in order to give them their journey. My job is to come in and try to make those words on the page come alive on camera.

For some reason I seem to be a massive hit with middle-aged women. I seriously don't know what it is.

What I can say that's different in American television… in Britain, they wouldn't cancel something after a couple of episodes. In the States they would. They would just decide it's not working, take it off and put something else in on the fall schedule.

My humour and my work ethic definitely come from my Scottish side, and I have to say the sense of humour doesn't really translate when I'm in America.

Never apologize for being nerdy.
