In one crucial respect, Steven Moffat’s work as Doctor Who’s current showrunner will come to an end before the regeneration scene in his final episode, the forthcoming Twice Upon a Time.
This is because the casting of the Thirteenth Doctor was decided by his successor, Chris Chibnall. “Jodie Whittaker – what an amazing, thrilling, brand new choice,” Steven tells us. “Like all of you, I’ve been poring over every picture, examining every performance, searing her into my brain. I see her face when I close my eyes. I now think she’s been the Doctor for 20 years! Remember that little announcement film? Fills me with nostalgia.
