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

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.

If you do something and it goes wrong, you learn from it and you move on.

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

Desperate Housewives' was a good experience, though, as I got to play the bad guy for once. My only complaint was they had me in a lot of sweaters.

You have to do bad things in order to become a hero. You have to make sacrifices.

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