The official Twitter page for BBC's Doctor Who has announced that filming and production is officially underway for the fourteenth season of the long-running science-fiction show. Season 14 will see Ncuti Gatwa officially take over as the Fifteenth Doctor, following on from David Tennant who has returned to the role for 2023 as the Fourteenth Doctor for a series of specials to celebrate the show's 60th anniversary. Gatwa will be joined by Millie Gibson as his new companion, Ruby Sunday, for his adventures through time and space.

Tennant revealed he had returned to the role 'by accident' as a result of taking part in lockdown watch-alongs with former Doctor Who showrunner Russell T. Davies. “It all slightly happened a little bit by accident,” he told the BBC. “The lockdown watch-alongs is where this all started. At a certain time and day everyone would press play on a certain episode and some of the people who had been involved in those episodes were tweeting along. I don’t tweet but my wife helped me."

Davies revealed in his monthly column for the Doctor Who magazine that he was continuing to work on scripts for the new series.

I sit here with ten scripts in front of me (four Specials and six episodes of the New Series, so far, with Episode Seven blinking away on the screen, first line: INT. COFFEE BAR, USA – DAY, 1947, and to continue an old tradition, I can tell you that Special One contains these three words: westerly, pelican, dreams).
