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.

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.

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

It wasn't until I got involved in Doctor Who that I started doing dramas on television.

Many things shaped my identity as a young boy: a strong selfworth (something that was instilled in all three Barrowman siblings by our parents), my immersion in theatre and music, and my DNA. I was born gay. It's not a choice I – or anyone else who is gay – made. If it were, why on earth would anyone choose to be part of a minority, part of a group that in so many cultures and countries, even in the twenty-first century, is regularly blasphemed, hounded and worse?

I've always said in my career and in my life I only do things I'm interested in.

Have I ever been the shy retiring type? Never. Not since the day I was born.
