Are there any big differences between working under Russell T Davies and Steven Moffat?
I think the main difference between them is, Russell is very much about big, bombastic brush-strokes. It's a real thrill going through one of his stories and very emotionally elating. With Steven, those clockwork robots of his represent his brain, really. He's very much about the individual pieces clicking together. But that said, there's a huge crossover between the two, because 'Midnight' was very much a Moffat-y sort of script, and something like 'The Beast Below' was very much like a Russell script. So there's a big, shared common ground between them, and they're both fantastic. They have a slightly different approach, but both love the show and they're brilliant to work with. In that respect, it's not really very different at all.
