Steven Moffat seems to have confirmed he will be around for another series of Doctor Who after teasing a big cliffhanger for his ninth season of the programme.
The BBC sci-fi showrunner told Doctor Who Magazine of his plans taking shape for series nine, even though series eight which will star Peter Capaldi as the Time Lord is yet to be screened later this year.
According to Metro, he wrote: "Sitting here, right now, just before the [series eight] finale shooting block, I've figured out the cliffhanger to the penultimate episode of the next series.
"Ohh, I don't think you'll see this coming!"
Meanwhile, a new trailer for series eight has been released, which shows Capaldi's Doctor apparently struggling with who he is, asking: "Am I a good man?"
Jenna Coleman, who plays Doctor's assistant Clara Oswald, is seen saying: "I don't think I know who the Doctor is any more," suggesting the new incarnation could have a tough time in his opening series.
Series eight of Doctor Who is due to air on BBC One in the autumn.
