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.

In everything I do, I find some of myself, or a lot of myself, and put it into the role.

I'm lively when I perform and I always put everything into a show, but when I get home I love lying down in front of the TV and relaxing.

Never apologize for being nerdy, because un-nerdy people never apologize for being assholes.

Whenever I'm in Glasgow I go and stand outside the front of the house I grew up in, which is in Mount Vernon.

I’m an openly gay man playing an omnisexual hero, who is loved on both sides of the Atlantic. How could I not be proud of that?

As an actor, I only play what is in the moment, rather than in the future, but sometimes the past is more important than what is coming up in the future.
