The BBC have released a trailer ahead of the return of Doctor Who later this month.
Doctor Who Flux is a six-part story that debuts in the UK and in the USA on Sunday 31st October, with a debut in Australia the following day.
It stars Jodie Whittaker in her final full series as The Doctor, although she will appear in three specials next year leading up to the regeneration of the thirteenth Doctor.
The images show the return of several classic monsters.
The six-part series is described by showrunner Chris Chibnall as six chapters of the same novel, the first time a series of Doctor Who has comprised a single story. The decision to make the series a single story was taken due to restrictions imposed by filming under COVID secure conditions.
Each episode has been written by Chibnall himself except for episode four which was written by Chibnall and Maxine Alderton, who wrote last seasons' story The Haunting of Villa Diodati.
The directing credits are shared by two directors. Jamie Magnus Stone has looked after episodes 1, 2, and 4. Stone directed the previous series opener, Spyfall as well as Praxeus; Ascension of the Cybermen and The Timeless Children.
The three remaining episodes have been directed by Doctor Who newcomer Azhur Saleem, who was recommended to the production team by composer Segun Akinola.
Alongside Whittaker is Mandip Gill returning as Yasmin Khan. They are joined by John Bishop, who plays Dan Lewis, the newest companion to step into and be amazed by the wonders of the TARDIS.
Returning to the series are the Sontarans, first created by Robert Holmes for the 1973 story The Time Warrior. Chibnall promises the Sontarans will pose a real threat to The Doctor with one episode focusing on the warriors. The look of the aliens has been updated by series designer Ray Holman who told Doctor Who Magazine he went back to the original design to get inspiration for their 2021 makeover.
Doctor Who: Flux can be seen on BBC One on Sunday 31st October at a time to be confirmed.
Jodie Whittaker has already filmed the final three episodes of her tenure as The Doctor which will be screened next year. Her final episode will be part of a special season making the 100th Anniversary of the BBC.
The 2023 season, making Doctor Who's 60th Anniversary, will be written by returning showrunner, Russell T Davies.
