John Barrowman on R T Davies:

Russell is probably the one writer around today who really has no fears of what people think. And he writes everything as it happens in society. Rather than having things that are glossed over and pretending that they don't happen, Russell writes about them, because as he says “I write about the way people live”.

And not only with all the other things he's done, but with Doctor Who, what he's done is he's been able to bring in the way people actually live but into a sci-fi show. And to engulf and bring in a children's audience, to an adult audience, to a teenage audience--in the UK it spans a whole gamut of things. It plays to three demographics. And, you know, Captain Jack is bisexual. It's never said full out on the show, but he is: he likes both men and women.

And the fact that Russell has done this...the British public have accepted it with open arms, because it's done with the right type of humour, the right type of realism. It's not salacious, it's not done in a rude or crude manner.

Russell takes a look at characters, particularly--and this is kind of going off Doctor Who a little--he takes a look at characters and people, and whether they be gay, straight, bisexual, or, you know, red, green, black, whatever they may be, or what they're into, he treats it as a norm. And that's why I think it's so acceptable amongst so many people.
