Mark Gatiss has "no idea" whether he will continue to write for 'Doctor Who' when the programme's showrunner Steven Moffatt leaves later this year.
The 50-year-old screenwriter hopes he'll be able to carry on creating content for the sci-fi series when Chris Chibnall takes over as executive producer at the end of 2017 but has admitted it'll be weird because he's worked with Moffatt for such a long time.
Speaking to the Radio Times magazine, he said: "I hope so, I've no idea. It's a funny thing, an end of an era. Obviously working very closely with Steven I feel it more than when Russell [T Davies, previous showrunner on 'Doctor Who'] left. I suppose there was more of a sense of continuity there, but I've no idea."
Chibnall is remaining tight-lipped on how he plans to shake up the show when he takes control in 2017 but it's not just fans who are being kept in the dark.
Gatiss explained to the publication: "I think Chris has got an entirely new writing team. I don't think anyone knows any details, which is kind of exciting!"
The question on everyone's lips at the moment is who will be taking over as the Doctor when Peter Capaldi - who joined the show in 2013 - steps down this year.
But it doesn't look like Chibnall has even decided who he wants to take the lead.
He said previously: "We'll cast the role in the traditional way: write the script, then go and find the best person for that part in that script. You couldn't go out and cast an abstract idea."
Some viewers have called for a woman to be cast and, although he's not giving it much thought at the moment, Chibnall has "a very clear sense" of what he wants.
He said: "The creative possibilities are endless, but I have a very clear sense of what we're going to do, without even knowing who's going to play the part."
