BBC has released the next time trailer for next week’s ninth episode of ‘Doctor Who’ Series 8, “Flatline.”

Episode Summary:

Separated from the Doctor, Clara discovers a new menace from another dimension.

But how do you hide when even the walls are no protection? With people to save and the Doctor trapped, Clara comes up against an enemy that exists beyond human perception.

“It’s a horror story. It starts off with a very …. idea and becomes really quite frightening by the end. A scary one. A proper scary one with one of our best ever sight gags in it. It runs throughout the episode and the climax of this particular gag, I think, is just glorious. I remember reading it out at the readthrough and everyone was just clapping and cheering at Jamie Mathieson’s idea.” – Steven Moffat

“Flatline involves different types of CGI creatures. I’ve still got some work to finish it off, but it’s looking good.” – Director Douglas Mackinnon told Daily Record
