Ep 2: Smile

By Frank Cottrell-Boyce

“There are some amazing ideas in this show, and some truly horrifying ones.”

Ep 3: Thin Ice

By Sarah Dollard

“Regency era, a frozen Thames, possibly an elephant!”

Ep 4: Knock Knock

By Mike Bartlett

“Mike was talking about the way oorboards creak – because, you see, he’s discovered the terrible truth…”

Ep 5: Oxygen

By Jamie Mathieson

“… one of my favourite episodes ever. I think you’re going to love this one. Clever and creepy, classic and brand new, this one’s got it all though.”

Ep 7: The Pyramid at the End of the World

By Peter Harness

“Basically, he wanted to find quick and efficient ways of wiping out all life on Earth. … the terrors of the modern world are never far away when Peter is in control of the TARDIS.”

Ep 8: The Lie of the Land

By Toby Whithouse

“… hand on my heart, this is his best one.”

Ep 9: Empress of Mars

By Mark Gatiss

The episode features an Ice Warrior hive on Mars with “lots and lots” of Ice Warriors and “some Victorian soldiers.”

Ep 10: The Eaters of Light

By Rona Munro

“I was properly surprised when she was happy to come in for a meeting, and I adored the script that came out of it. But I don’t think I really understood how wrong I’d got her, until I saw her wandering around the studio, taking selfies with Daleks, Weeping Angels, and the TARDIS. You see that Rona Munro, of international renown? She’s a Doctor Who fan, she is.”
