"In terms of Jack's sexuality it was a really bold thing that Russell [T Davies] did putting him right in the middle of a show at seven o'clock. For young people to see a character who is such a positive role model, who is honest and decent and good and a hero, and for him to have a sort of non-defined sexuality I think it's a really important thing to see. Your sexuality doesn’t make you a good or bad person. And John was really keen on that too, he was really excited about the opportunity to do that I think."
