Russell T Davies was at a wedding recently when a guest complained about what he'd done to Doctor Who, an otherwise wholesome family drama. "She told me she was shocked because Captain Jack is bisexual and wouldn't let her children watch it," says Davies. "I had such a go at her. I said: 'You're an unfit mother. You're ignorant. Your children are cleverer than you.' Then her husband came up and I thought there was going to be a fight, but they left."
Davies takes a drag on his cigarette, exhales and gives me a self-satirising glance: "I can be very bolshie, you know."
