Steven Moffat has promised a “whopper” of a cliffhanger, towards the end of the “next series” of Doctor Who.
In Doctor Who Magazine issue 475, Moffat is asked how far in advance he plans, to which he replies: “One series at a time, largely. I suppose, I had a fair amount of Trenzalore worked out (The Doctor trapped in a war for a thousand years) when I wrote ‘The Eleventh Hour’, but that’s really the exception.”
He went on to talk about the “next series” of Doctor Who: “Sitting here, right now, just before the finale shooting block, I’ve figured out the cliffhanger to the penultimate episode of the next series. And it’s a whopper. Ohh, I don’t think you’ll see this coming!”
Doctor Who Series 8 will air in August 2014 on BBC One.
