Monsters & Villains



2016 Christmas Special

The Return of Doctor Mysterio

Written by Steven Moffat. Directed by Edward Bazalgette.


The Christmas special is the only Doctor Who episode to air in 2016. The festive outing will not feature Pearl Mackie as new companion Bill. Matt Lucas instead will fill the void returning to the show as Nardole, last seen in The Husbands of River Song. In the story the Doctor joins forces with an investigative journalist, played by Charity Wakefield, and a superhero, played by Justin Chatwin, to save New York from a deadly alien threat.

2017 Episodes

1. The Pilot

Written by Steven Moffat. Directed by Lawrence Gough.


The opening episode of Series 10 marks the introduction of new companion Bill, played by Pearl Mackie. Matt Lucas will also once again reprise his role as Nardole. Stephanie Hyam will guest as Bill’s friend Heather. Features “killer puddles” and Daleks.

2. Smile

Written by Frank Cottrell-Boyce. Directed by Lawrence Gough.


The second episode, from In The Forest of the Night writer Frank Cottrell-Boyce, was part filmed overseas in Spain, which will be serving as a futuristic city in the story. Features killer robots that have emoji faces. They like to give hugs, then reduce their victims to skeletons.

3. Thin Ice

Written by Sarah Dollard. Directed by Bill Anderson.


The Doctor and Bill take a trip back into the Regency era in Sarah Dollard’s second script following Face the Raven. Features a serpent-like monster that lurks under the frozen Thames.

4. Knock Knock

Written by Mike Bartlett. Directed by Bill Anderson.


Veteran actor David Suchet leads the guest cast as “the Landlord” in Who newcomer Mike Bartlett’s debut story. Suchet has said he is not playing a Time Lord. Reportedly we find out why the floorboards squeak – there are giant woodlice in there.

5. Oxygen

Written by Jamie Mathieson. Directed by Charles Palmer.

A space based story. Mathieson described his episode as “Very, very scary. Like, seriously so. ‘Let’s go behind the sofa and just stay there until it’s over’ scary. It’s got more shocks and tense scenes than anything I’ve ever written. It’s also a taut thrill ride, a gag test, a pitch black satire and, for the first time I’m writing for Bill and Nardole!”

6. Extremis

Written by Steven Moffat. Directed by Daniel Nettheim.

Steven Moffat’s mid-series episode will mark the beginning of a three-parter, an Earth-invasion story featuring monks as the threat. Michelle Gomez will also return as Missy.

9. The Empress of Mars

Written by Mark Gatiss. Directed by Wayne Yip.

10. The Eaters of Light

Written by Rona Munro. Directed by Charles Palmer.

Classic series writer Rona Munro returns, who previously wrote the 1989 Seventh Doctor adventure Survival. The episode is said to be “haunting”. Features Romans soldiers.

The Mondasian Cybermen are back in the two-part finale – the original version of the Doctor’s deadly enemies who hail from the planet Mondas and have not been seen in the show for over fifty years. Michelle Gomez will also be back once again causing trouble as Missy.

2017 Christmas Special

Written by Steven Moffat. Directed by TBC.

Steven Moffat and Peter Capaldi’s final episode as Doctor Who showrunner and the Doctor, respectively. On approaching his last story Moffat said: “The departure of a showrunner doesn’t mean anything to the audience. Most of the audience doesn’t know that I exist, so they’d go blank if I attempted to wave goodbye to them. Oh, the embarrassment that would be. So I’m damned if I’m imposing my departure on the show. I just want to do a good one, before I hand over to Chris [Chibnall].”
