The sinister Sandmen could be making a comeback.

If you enjoyed tonight’s Doctor Who, then the good news is that a sequel could be coming your way.

Mark Gatiss revealed to press including Digital Spy that Who showrunner Steven Moffat has asked for a follow-up to ‘Sleep No More’.

“Steven’s asked me if I’ll write a sequel – I’ll see if I can do that,” he said. “If I can think of one, I would certainly like to do it, because I think the idea is good and the monsters are great.”

The ambiguous climax to ‘Sleep No More’ certainly hints at a return for the sinister Sandmen, with Gatiss hinting at a very different setting for the sequel.”I suppose you’d have to think… where else would they go?” he said. “But the Doctor loses in this episode and that’s an unusual place to be, so it sort of needs some closure.”Having penned eight episodes of Doctor Who since the show’s relaunch in 2005, Gatiss insisted that he still has plenty of ideas for more scripts – though some are just “nuggets, tiny things”.

“I’d love to do a story about fracking – it seems to me like an incredibly Doctor Who idea,” he said. “Because it’s obviously a bad idea, no matter what the supposed rewards.

“As well as shale gas, maybe there’s something else lurking under there… I’d like to do that. I’d call it, ‘Frack Off and Die’!”

Gatiss also admitted he wouldn’t be adverse to adapting one of his previous Doctor Who works – the Big Finish audio play Invaders from Mars – for television.

“It’s set on the night of Orson Welles’ War of the Worlds broadcast, and there’s a real invasion,” he explained. “It came out delightfully for Big Finish 13 years ago, but I think that’d be good. If you have a good idea, go back to it!”

Doctor Who continues next Saturday at 8.10pm on BBC One.
