Doctor Who Season 12 Episode 1 Spyfall, Part 1 (1)

The twelfth series of the British science fiction television programme Doctor Who premiered on 1 January 2020 and is set to air through to March 2020. The series is the second to be led by Chris Chibnall as head writer and executive producer, alongside executive producer Matt Strevens. This series is the twelfth to air following the programme's revival in 2005, and is the thirty-eighth season overall. The twelfth series is set to be broadcast on Sundays, bar the premiere episode, continuing on from the eleventh series, after regular episodes of the revived era have previously been broadcast on Saturdays.

Jodie Whittaker returns for her second series as the Thirteenth Doctor, the most recent incarnation of the Doctor, an alien Time Lord who travels through time and space in the TARDIS, which appears to be a British police box on the outside. The series also stars Bradley Walsh, Tosin Cole and Mandip Gill as the Doctor's travelling companions, Graham O'Brien, Ryan Sinclair and Yasmin Khan, respectively.

The ten episodes were directed by Jamie Magnus Stone, Lee Haven Jones, Nida Manzoor and Emma Sullivan. Alongside Chibnall, who wrote four scripts for the twelfth series, the writers include Ed Hime, Pete McTighe and Vinay Patel, who return from writing for the previous series, as well as new contributors Nina Métivier, Maxine Alderton and Charlene James. Filming for the series commenced in January 2019 and concluded by November of that year. The series will be followed by a special episode.
