Series 12 (Doctor Who)

Series 12 of Doctor Who was due to premiere in "very early" 2020. Chris Chibnall remained in the position of executive producer whilst Jodie Whittaker, Tosin Cole, Mandip Gill and Bradley Walsh reprised their roles as the Thirteenth Doctor, Ryan Sinclair, Yasmin Khan and Graham O'Brien respectively.

Whittaker announced her own return on Friday 7 December 2018, two days prior to the broadcast of the series 11 finale, The Battle of Ranskoor Av Kolos. The series was announced almost immediately after the conclusion of said episode.

Return to familiarity
As a huge difference from the complete reinvention from series 11, series 12 would return to more familiar ground, apparently hearkening back to the Russell T Davies and Steven Moffat eras.

Series 12 would go back to being "darker and scarier" in an attempt to stray from the lighter and more informative tone of the previous series.

Actress Dominique Maher recorded ADR (additional dialogue replacement) for her character in an Australian accent.

After having disappeared from series 11, having been replaced by a New Year Special, the Christmas Special returned for series 12.

Returning foes
Series 12 re-introduced the Judoon, giving them a central role in a television story for the first time since the series 6 mid-series finale A Good Man Goes to War in 2011.

The Cybermen also made their way back onto the small screen this series, in their first TV appearance since 2017 story The Doctor Falls (discounting archival footage in Twice Upon a Time) in a way that would inspire Mary Shelley to create Frankenstein.

The Daleks also made their way back, in their bronze design, albeit with a new black Dalek casing design introduced for one of them.

Promotion
On 31 October 2019 the BBC released the first proper promotion of the coming series 12, in the form of a poster showing a shadow of the Thirteenth Doctor cast in the yellow light from the open TARDIS doors in the bottom corner. A faded rainbow appears across her chest, and the tagline says "Watch this Space".

On 10 November, the BBC released a promo teaser for the new series on the Official Doctor Who YouTube Channel, with the camera zooming fast through a purple vortex to a region of space in which the TARDIS suddenly appears and zooms across, revealing first the tagline "Watch this Space" then the "Doctor Who" logo and the text "Coming Soon". The "Doctor Who" page itself said "Make Space... 23/11/19".

At a Q&A session held at Sheffield Hallam University on 19 November, Chibnall told the audience that the opening story would be "the biggest episode in the show’s history". A BBC One source to The Mirror said that "It’s going to be huge. The scale is just epic. No one will be disappointed." Whittaker added that "I feel like we’re treading new ground for each of the character journeys, and the development of everybody’s storylines."

On 21 November the "Doctor Who" page posted a new poster, this time showing the entire main cast on a white background at the top and a region of space at the bottom. The poster said "Space. For All." as well as "Coming Soon".

Myths

 * Although now debunked, Starburst Magazine had reportedly been in contact with the BBC back in November 2018, during which time, the BBC said that series 12 would air in Autumn 2019.
