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

I trust the [series] writers when I'm filming, because it's interesting for me to go in every week and see what's going to happen, and the challenge for me as the actor is to make it work.

If you put a label on yourself, people will pigeonhole you.

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.

You can be in the public eye all the time and still have a private life, but the important thing is to keep in touch with the people who put you there.

You know, every year 'Torchwood' has become something a little different than it was before. It's still sci-fi, but it doesn't just deal with spaceships and aliens all the time, because we've done that. Our science fiction is more psychological.

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