The Witch's Familiar
"The cliffhanger from episode one feels so important to get out of, so I can't say much about this. We're going to see the Doctor trapped and alone, facing his greatest enemy and a terrible temptation. We see more of a Dalek city than ever before, and we're going to surprise you with this episode."
Under The Lake
"Ghosts on an underwater base! Add in time travel and we realised that in Doctor Who you could be haunted by your own ghost. A hugely exciting episode with some of our scariest moments yet. And you won't see the cliffhanger coming."
Before The Flood
"Set a few hundred years before episode three... The Doctor needs to unpick the past to solve the future."
The Girl Who Died
"We couldn't believe the Doctor hadn't properly met Vikings before. They find themselves in a small, fighty Nordic village, with the Doctor doing all he can to persuade them not to fight the alien warriors that are menacing them. It doesn't quite work out as he planned."
The Woman Who Lived
"A beautiful episode centred on the Doctor and Maisie Williams' character. There's a Highwayman menacing London, an alien lurking in the woods, and comedian Rufus Hound stealing every scene."
The Zygon Invasion
"Some rogue Zygons are trying to destabilise the peace and start a war between Zygons and humans. We've gone global on this with stories split across the world."
The Zygon Inversion
"The UK has been taken over by shape-shifting Zygons, Clara is in a whole world of trouble... It's a bit of an Invasion of the Bodysnatchers..."
Sleep No More
"This episode is assembled from footage found in the wreckage of a crashed space station. We're just putting it out as it was discovered."
Face The Raven
"Sarah [Dollard, writer] had an idea about all those little side streets that don't actually exist, but what if they do, and what it actually inside them? Rigsy [from Flatline] is back, and he's in trouble. He woke up with a tattoo on his neck and it's counting down. No-one knows what happens with it hits zero..."
"This is a 'single-hander' which only features the Doctor and no-one else. It's the first time we've ever done an episode like it. And it's the most virtuoso, fantastic piece of writing from Steven [Moffat, lead writer]."
