"I do watch a lot of television science fiction, and it is a particularly sexless world. With a lot of the material from America, I think gay, lesbian and bisexual characters are massively underrepresented, especially in science fiction, and I'm just not prepared to put up with that. It's a very macho, testosterone-driven genre on the whole, very much written by straight men. I think Torchwood possibly has television's first bisexual male hero, with a very fluid sexuality for the rest of the cast as well. We're a beacon in the darkness."
