The first trailer for Doctor Who Season 13 is here - and sets up an epic adventure for Jodie Whittaker's final season in the TARDIS.
Subtitled Doctor Who: Flux, the season marks the first time since the 1980s that the iconic sci-fi series has departed from its standard episodic format, spreading a single narrative arc over multiple installments. (Think Torchwood: Children of Earth for a more modern frame of reference.)
The specifics of the story are still clearly very much under wraps, but the season will see the arrival of John Bishop as Dan Lewis (though how exactly Flux will introduce a new companion in all this is anyone's guess!) and feature Game of Thrones alum Jacob Anderson in a major guest role.
The one-minute clip gives us virtually no further information about what the titular "Flux" is specifically or how the story of the six-episode story will play out. But it does give viewers tantalizing glimpses of many of the monsters that are apparently somehow involved, including Sontarans, the Ood, Cybermen, and the Weeping Angels.
Watch for yourselves below.
The BBC also announced a raft of Season 13 guest stars, including Cold Feet's Robert Bathurst, The Irregulars' Thaddea Graham, The Inbetweeners' Blake Harrison, Downton Abbey's Kevin McNally, Line of Duty's Craig Parkinson, Unforgotten's Sara Powell, Britannia's Annabel Scholey, and The Crown's Penelope Ann McGhie.
The six-episode Season 13 begins Sunday, October 31. The first of Whittaker's final specials leading up to Thirteen's regeneration will premiere on New Year's Day and the second feature is slated to air at some point in the spring. Whittaker's third and final installment will air in Fall 2022, to coincide with the BBC's 100th anniversary.
