Russell T Davies is the writer behind the wildly successful reinvigoration of Doctor Who.

He’s also the man responsible for that show’s two spin-offs: the adult-orientated Torchwood and the kiddie-friendly Sarah Jane Adventures.

The Bafta-winning writer told us the secrets of writing a hit children’s drama.

Don’t give yourself do’s and don’ts rules
“It’s just instinct. We don’t have a list of regulations about what we do and don’t show. It’s just the way you use a different part of your mind when you’re talking to a child than when you’re talking to an adult. Maybe you use more of your mind when you’re talking to a child.”

Don’t be afraid to moralise
“The Sarah Jane Adventures has an entire tone and style of its own, which sometimes does go into a Moral Of The Week. But I don’t think there’s anything wrong in that. I don’t want to hit people over the head with it, I don’t want to do a big He-Man speech at the end of the episode. But all stories are moral. There are no immoral or amoral stories.”

Make it scary
“I think with scares they work best when they’re everyday things. One story this season is about horoscopes. I think it’s good to scare children. Television shouldn’t be there to make you smile all the time. You need to be scared by it and you need to be upset by it sometimes. I think that’s a good viewing experience –- a good range of emotions.”

Be obtuse about your star guests
“Will the Doctor appear in Sarah Jane? It’s possible. He’s not in this series, I can tell you that. But of course I would lie if he was. But if he was in it, CBBC would be screaming it from the rooftops! But no, he’s not in it. Actually, I don’t even like him very much! Isn’t he in panto now?”
