Series 13 (Doctor Who)

Series 13 of Doctor Who, also referred to as Doctor Who: Flux, premiered on Sunday 31 October 2021. Chris Chibnall remained as executive producer, whilst Jodie Whittaker returned as the Thirteenth Doctor. Mandip Gill returned as Yasmin Khan, joined by newcomer companion Dan Lewis, played by John Bishop. The series opened with The Halloween Apocalypse and concluded with The Vanquishers, before being followed by a trilogy of specials in 2022; a New Year Special, Eve of the Daleks, an Easter Special, Legend of the Sea Devils, and BBC Centenary Special The Power of the Doctor.

In July 2021, it was announced that both Chris Chibnall and Jodie Whittaker would be departing at the end of this series, making good on a private agreement between the two to leave the programme after three series. On 20 July 2022, composer Segun Akinola announced on his social media platforms that he would also be leaving Doctor Who after production of the BBC Centenary Special.

Although initially reported in an announcement by Chibnall that this series would only contain 8 episodes, it was later announced that, in addition to the six episodes of the main series and two specials following in 2022 (similar to those at the end of David Tennant's run), a further feature-length special was in the works for the end of the era. Including this new "trio of specials", the total count was brought up to 9. The reduced episode count from the usual 11 was due to constraints running a production during the COVID-19 pandemic.

At San Diego Comic Con @ Home on 25 July 2021, it was also announced that the main series would follow a serialised format, meaning it would be one serial spanning six episodes, similar to Torchwood: Children of Earth (and most Doctor Who television stories prior to the 1996 TV Movie).

At a press event held on 19 October 2021, it was revealed that the main series would be comprise one single story known as Flux, which would be told over 'six episodes – or chapters, as they're going to be labelled' and 'changes the way we deal with characters – characters who go across more than one episode, monsters who go across more than one episode.'

A series of behind the scenes features were released to YouTube.

The series continued the ongoing storyline exploring the Doctor's past and the Timeless Child.

The series also explored a new subplot of the Doctor's TARDIS heavily malfunctioning and decaying over the course of the storyline, something that reached a conclusion in the New Year Special when the Doctor reset the TARDIS system.

Storyline continuation
According to Chris Chibnall, the previous series finale Ascension of the Cybermen/The Timeless Children laid the groundworks of the storylines throughout this series.

On 8 October 2020 at the live-streamed New York Comic-Con panel, Mandip Gill revealed that series 13 would delve deeper into Yasmin Khan's past and touch on "mental health issues".

On 5 December 2020, Gill told Radio Times that while her co-stars, Bradley Walsh and Tosin Cole, felt ready to leave during the preceding New Year Special Revolution of the Daleks, she was not ready to leave the TARDIS behind, saying there's still more to explore about Yaz's past and mental health.

On 1 January 2021, following the broadcast of Cole and Walsh's final scenes, comedian John Bishop was officially announced in a teaser trailer as playing incoming companion, Dan.

In an interview shared by the BBC on 24 October, Matt Strevens mentioned that series 13 would solve some loose ends from the reveal in the preceding series, saying that "[series 13] picks up on a lot of the things the Doctor learned about herself and her history at the end of series 12."

Returning foes
Similar to the preceding series 12, series 13 would see the return of numerous aliens and villains.

The Sontarans returned as significant antagonists for the first time since series 4's The Sontaran Strategem / The Poison Sky. However, several Sontarans had appeared in the time inbetween, most notably Strax - last seen in series 8's Deep Breath. For series 13, the Sontarans' appearance was redesigned, with their armour being recoloured silver and appearing more weathered, similarly to the appearance of the Sontarans first seen in the 1974 story The Time Warrior.

The Weeping Angels also returned as significant antagonists for the first time since the 2013 Christmas Special, The Time of the Doctor - although they made numerous cameo apperances in the time inbetween, the last of which being the 2021 New Year Special, Revolution of the Daleks.

The Cybermen, specifically the Cyber-Warriors, also returned after debuting in the Series 12 finale, Ascension of the Cybermen / The Timeless Children. Additionally, Ashad returned in the The Power of the Doctor.

The bronze Daleks also returned after serving as the main antagonists in Revolution of the Daleks. For series 13, they made two cameos in the episodes Once, Upon Time and The Vanquishers, before returning as the main antagonists in the 2022 New Year Special, Eve of the Daleks, concluding a trilogy of New Year Specials with them as the main antagonists. They returned once more in the Centenary Special The Power of the Doctor. For Eve of the Daleks, a new variant of Dalek, Dalek Executioners, debuted, although unlike those of the spin-off series Time Lord Victorious, these Dalek Executioners were bronze Daleks with a remodeled gunstick resembling a Gatling gun.

The Sea Devils also returned for the Easter Special Legend of the Sea Devils, having last been seen in 1984 story Warriors of the Deep.

The Master also returned as a significant antagonist in the The Power of the Doctor after having last appeared in the series 12 finale, Ascension of the Cybermen / The Timeless Children.

Production during COVID-19
On 31 March 2020 it was reported by Radio Times that due to a lucky break in filming, Doctor Who might have dodged a bullet and inadvertently gone around the whole Lockdown crisis that other production have suffered, and therefore escaped the COVID-19 virus altogether.

However, it was reported on 18 June 2020 by The Mirror that Director of BBC Wales Rhodri Talfan Davies had said that the series would not be continuing filming during current social distancing rules.

On 11 September 2020 it was claimed by the Metro Entertainment that due to a spike in COVID-19 cases, series 13 could potentially be moved to 2022 due to significant delays in principal photography as a result of the virus.

That same day, a conflicting report from Radio Times mentioned that filming was set to begin "soon", noting that little was known about what social distancing rules would mean for the series or the number of episodes.

On 11 November 2020, Chris Chibnall announced to The Mirror that the series run had indeed been impacted by the virus, and had been reduced to eight episodes. He stated: "In this strangest of years, the Doctor Who production team have worked wonders to get the show back into production. Given the complexity of making Doctor Who, and with new and rigorous Covid working protocols, it's going to take us a little longer to film each episode, meaning we expect to end up with eight episodes, rather than the usual 11."

In an interview with the Radio Times on 28 November, Chibnall opened up a bit more about the struggles of making the show during a global pandemic while trying to avoid fans thinking about the pandemic while watching the series, saying: "Basically, for the past six months we've been going, 'How do we make Doctor Who in the middle of a pandemic?' We had to re-interrogate absolutely everything. We couldn't do Spyfall this year. We won't be able to do overseas filming. Editorially, production-wise, logistically, health and safety-wise, it's had a massive impact. But where we are is incredibly exciting. As much as possible at the moment everybody's smiling, and we've got some really lovely, great, mad scary ideas."

Producer Matt Strevens reassured fans that the quality of the series would not be affected, saying: "The biggest thing is that when series 13 finally does air, whenever that is, we never want people to watch it under the caveat of COVID, going, 'Ah, well, but they made this during the pandemic.' We want to make sure that when you watch it, it's – no pun intended - timeless, and feels as exciting and as high-end as we've tried to make the series since we took over. That was the driving impulse behind looking at the narratives and reducing the number of episodes slightly: we want to make sure we can give people the biggest production values possible."

On 25 July 2021, during the Comic Con @ Home, Chibnall announced that the series had undergone changes in format, giving it a storytelling style similar to Classic Who era, with it being a singular multi-part story throughout the entire season.

In Doctor Who Magazine issue 570, Whittaker spoke about the difficulty of shooting a particular scene set in a small bedroom due to social distancing rules applying still and preventing all crew getting into the room together.

Chibnall further stated that it had been incredibly difficult on set to get the show done, saying they had to "reimagine their job", however that they had been able to "do all the things [we] normally do in terms of character interactions".

In an interview shared by the BBC on 24 October, Jodie Whittaker spoke about what it was like filming during the pandemic, saying that the filming started late because of it and there was a whole different feel to get used to because of the travelling restrictions preventing overseas filming and because no one had seen eachother for a year and that "[everyone] want[ed] to make sure [they're] not the person to make a mistake as the domino effect [could] be so catastrophic on set".

Producers
In an interview with Television Magazine in June 2017, Chibnall promised that his run would be "bold" and "risky". . (Contrary to common belief, he made no mention of a five-year plan, but his friend, James Strong indicated his belief that the position was a five year project. ) This plan involved the revelation of the Timeless Child, given at the end of series 12.
 * Interestingly, the five-year-plan would come to pass with the Centenary Special releasing on 23 October 2022 completing the run which had begun when filming for the "Chibnall-era" began on 31 October 2017 with series 11.

Chibnall revealed to Doctor Who Magazine #568 on 19 August 2021 that he would be "free and clear" of the show's production in 2022, the year of the specials.

Director
Jamie Magnus Stone returned to direct the first filming block from this series, along with DOP Robin Whenary consisting of episodes 1, 2 and 4. Stone also directed the Centenary Special.

Azhur Saleem directed the second filming block consisting of episode 3, 5 and 6 of the series.

Episode notes

 * Possibly as a way of marketing, a recurring theme in the Doctor Who logos was that over the course of the series, they would gradually break apart, similar to Time and Space as seen in the series, with the rainbow coloured threads at the end of each YouTube video unravelling more and more, while the BBC WHO logo would shatter further and further.
 * The specials following the main series were also given their own uniquely themed logo variants across social media.
 * Series 13 marks the first time the title sequence has received a subtitle, in this instance Flux, below the main title of the show.
 * Jodie Whittaker said she "cried her eyes out" on her final day of filming.
 * Flux is the first serial since season 26 and the first 6-part story since The Armageddon Factor (discounting the unaired Shada and animated story Dreamland).
 * Despite being the shortest season in the history of the show in terms of episode count, Flux formed the longest continual storyline in the revived series as of 2022 (at just over 320 minutes in total, across six episodes), and is the second longest-running serial only beaten by The Trial of a Time Lord (at around 350 minutes total, across 14 episodes) as of 2022.
 * The main Series 13 was the first season since Season 23 of the Classic Series to not introduce any new writers.
 * It is also the only season to have only two credited writers, and the first time the current showrunner has written all episodes, with only episode 4 having a co-writer.
 * The three specials that followed, followed the same style, with only special 2 being co-written.
 * Pete Levy directed the shot of the Doctor looking through the long disposal shaft in the TARDIS console in The Vanquishers.
 * As a result of the passing of Queen Elizabeth II on 8 September 2022 the marketing for The Power of the Doctor got messed up due to a "10 Day Mourning Period", which caused the 582 issue of Doctor Who Magazine to be released (15 September) before the official reveal of the title, which got pushed to 21 September.
 * The large gap between the broadcast of the Centenary Special, released in October 2022, and the broadcast of the 60th Anniversary Special (Series 14), released in November 2023, marks the second time since the tradition began, that a Winter Special has been ommitted.
 * The first time this happened was when the Series 12 opener Spyfall: Part One was broadcast on New Year's Day 2020 instead.

Announcement
Unusually, the series was announced as being "in the works" by Chibnall on 21 November 2019, a little over a month before the previous series began airing.

In May 2017, it was announced that due to the terms of a deal between BBC Worldwide and SMG Pictures in China, the company has first right of refusal on the purchase for the Chinese market of past and future series and spin-offs of the programme.

In October 2019, it was revealed that due to the show heading to HBO Max, the network had struck a deal for additional series of the programme.

Whittaker briefly mentioned her return in Doctor Who Magazine on 9 December 2019, a little under a month before series 12. She later spoke about it publicly to Entertainment Weekly on 22 January 2020.

Promotional material
Following the broadcast of Revolution of the Daleks on New Year's Day 2021 was an introduction clip promoting this series featuring two men loading a truck while reading horoscopes. The horoscope in question read amongst others that "lucky number is 13, the colour blue will be important", the camera then pans to John Bishop and flashes a few brief clips of various sequences from the upcoming series. This new upcoming companion was later revealed to be named "Dan". Bishop himself said of the experience: ''If I could tell my younger self that one day I would be asked to step on board the TARDIS, I would never have believed it. ''

On 25 July 2021 San Diego Comic Con @ Home was held to promote the new series, with John Bishop, Mandip Gill Jodie Whittaker and Chris Chibnall, in which they talked about the changes made to the series along with what it was like to work on set during pandemic times and their favourite things about it, also each sharing a word to describe the series: "Riveting", "Inspirational", "Mysterious" and "Swarm". The panel also introduced a special guest Jacob Anderson as recurring character Vinder. At the end of the panel, the Series 13 trailer was shown, and following that it was released on the Doctor Who YouTube Channel. At the panel were also shown publicity photos of the new Team TARDIS and Vinder, respectively.

On 29 July it was announced on the Doctor Who website that Jodie Whittaker and Chris Chibnall would be handing over the control of the show to someone else following a 6-part event series and a trio of specials stretching all the way into autumn 2022 as part of the BBC Centenary celebrations. Chibnall said of the experience: "Jodie and I made a "three series and out" pact with each other at the start of this once-in-a-lifetime blast. So now our shift is done, and we're handing back the TARDIS keys. Jodie's magnificent, iconic Doctor has exceeded all our high expectations. She's been the gold standard leading actor, shouldering the responsibility of being the first female Doctor with style, strength, warmth, generosity and humour. She captured the public imagination and continues to inspire adoration around the world, as well as from everyone on the production. I can't imagine working with a more inspiring Doctor – so I'm not going to!" to which Whittaker adds: "''In 2017 I opened my glorious gift box of size 13 shoes. I could not have guessed the brilliant adventures, worlds and wonders I was to see in them. My heart is so full of love for this show, for the team who make it, for the fans who watch it and for what it has brought to my life. And I cannot thank Chris enough for entrusting me with his incredible stories.''"

On 16 August the official Doctor Who social media accounts posted a new publicity photo. The photo featured Jodie Whittaker, Mandip Gill and John Bishop as the Doctor, Yaz and Dan, respectively, in front of a graffitied brick wall.

On 18 August BBC America, in conjunction with AMC Channels, released a summary of the upcoming series. In this summary it was revealed the Series would have "terrifying new adversaries" as well as "truly iconic old enemies" and that the Doctor would "be questioning everything about her past" and that she would "undoubtedly be searching for answers". The summary further said that the audience should expect "action", "fun", "scares", "new worlds" and that Team TARDIS would be confronting "a deadly evil".

On 19 August Chris Chibnall told Doctor Who Magazine that he was originally only supposed to do 8 episodes consisting of the 6-part serial and two specials, but earlier in the year was contacted by BBC Director of Content Charlotte Moore about doing a celebratory Centenary Special, to which he agreed and following that "numbers were crunched, conversations were had, deep breaths were taken, more testing kits were ordered, and contracts were extended".

On 2 October, a 5 second "interruption" was broadcast on BBC One featuring the Thirteenth Doctor in the TARDIS attempting to get the audiences attention before being cut off by static noise.

The same "interruption" was shown on 3 October, this time a bit clearer.

On 4 October the "interruption" was broadcast again, with the same change as before being that it became a bit clearer picture.

The "interruption" was put out once more on 5 October, again with minor changes making it clearer than before.

The "interruption" aired once again on 6 October, once again a little clearer than before.

In the SFX Magazine issue released on 6 October it was revealed that the release date of Series 13 was "imminent" as given in this message: " YES, IT'S THIRTEEN'S LAST FULL SERIES AND YES, IT'S ONLY SIX episodes, but it's landing imminently (yes, there's an embargo) and there's a new companion (or possibly two?). It'll come as little surprise that details are very thin on the ground for Jodie Whittaker's final "full" series, but we can confirm that John Bishop joins the "fam" as Dan, and Jacob Anderson guest stars as Vinder alongside Mandip Gill as Yaz.", alongside 3 exclusive images from the series itself.

On the same date, the Doctor Who social media accounts posted a picture of a Sontaran flagship hovering above the Liverpool docks at George's Pier Head. This spacecraft was reportedly projected across the night sky.

On 7 October the "interruption" was aired yet again, however, contrary to previously, this time it was made more static.

At 5 PM BST on 8 October, the Doctor Who social accounts posted the "interruption”.

Shortly after, they cryptically posted "++ ---/CAN YOU HEAR ME?/ ---++", the same message as given in the static-filled "interruption", followed by an immediate shutdown of all active Doctor Who social media accounts.

Later that same day, the "interruption" was broadcast again. This time with no changes at all to the static.

Early in the morning on 9 October the BBC reactivated the Doctor Who website with terms and conditions for something called  Have You Seen The Aliens. The page thanked viewers for informing the Doctor on any aliens in the area. Concurrently, the BBC showed the "interruption" on billboards around Liverpool, featuring the tagline "It's Coming, Be Ready" written in the Doctor Who logo font and a phone number, 0800 678 3110, to be used to report sightings of any aliens.

The same evening, all the Doctor Who social media accounts went back up with a new poster featuring the Thirteenth Doctor, announcing that the new series would be called Flux and would begin broadcast on Halloween, 31 October 2021. The finished version of the "interruption" on YouTube, a minisode named The Flux is Coming..., was also released; it had premiered on BBC One earlier in the day. The minisode reveals that something called The Flux is following the Doctor, bringing with it Sontarans, Weeping Angels, creatures called the Ravagers and other enemies from across the universe, and that the Doctor and her companions were in the fight of their lives.

After all that, the Doctor Who Twitter posted a The Doctor Returns gif.

On 14 October the Doctor Who Magazine issue number 570 was released which offered a look at the new Sontarans, revealing them to be similar to the design from 1974 story The Time Warrior. Furthermore, DWM revealed the list of writers for Flux, with all episodes being solely written by Chibnall except episode 4, which was co-written by Maxine Alderton. Of the new format, Whittaker mentioned the familiarity of it, having lived it on Broadchurch and further said of the series: "This season is going to take you on a labyrinthine adventure, the Doctor is going to find things out about herself and is going to face some of her biggest and oldest foes. And she won't be able to do any of that without Yaz and Dan standing by her side."

Chibnall further stated that the series would start off with "cataclysmic events".

In the evening on that date, the Doctor Who social accounts asked fans if they wanted a trailer the following day, using a "It's Coming, Be Ready" gif.

On 15 October, Jodie Whittaker appeared on The Graham Norton Show talking about the new series, saying that she had filmed her regeneration scene, but didn't know who the Fourteenth Doctor would be. She further said that: "I'm not allowed to tell you anything, but I can say the first episode is out on Halloween and it is a six-episode story arc – it's like a six-hour film and it is amazing.".

The second trailer was also released, giving a further look into what could be expected from the upcoming series, naming it as "one epic story over six thrilling chapters". Matt Strevens said of the series "I can't wait for the audience to come on the Flux ride with us. It's our biggest adventure yet with so many brilliant new characters to fall in love with. We had a blast making it."

That same date, John Bishop told in an interview with The Times that his character Dan gets to live throughout the entire experience and that he, Yaz and the Doctor would have some banterish moments throughout it all.

At a press event held on 19 October, Chris Chibnall revealed further details about the series, namely the release of new promotional pictures along with an additional list of guest characters.

Speaking at a webinar on 20 October, Chibnall further promised the series would "blow up the universe" and that it would consist of the "biggest-ever cliffhangers".

On the same date the title of the first episode was released by the Doctor Who accounts, calling it The Halloween Apocalypse, and releasing it alongside a synopsis promising that "an ancient evil is breaking free"

On 24 October, another batch of promotional pictures were released to the public, picturing several of the characters to appear in the series.

The same day, the BBC shared an interview with Matt Strevens in which he revealed that the new series evolved late in the day after the COVID-19 pandemic struck again, saying that the end result turned out to be something completely new, saying "I can honestly say it's not like the previous two series. It's huge in its scope and its scale and the jeopardy.".

Another interview was shared, this being with Jodie, in which she spoke about what it was like filming her last series and whether it had changed her way of approaching a different serialised format and what it's like to be recognized on the street, finally describing the series as a "self discovery rollercoaster".

On 25 October, Radio Times revealed the title of the second episode, War of the Sontarans along with the synopsis promising a pitched battle between the Sontarans and the British Army and an "ancient temple hides mysterious secrets".
