"The Robot Revolution" is the first episode of thefifteenth series of theBritish science fiction television seriesDoctor Who. The episode was written byRussell T Davies, theDoctor Whoshowrunner, and directed byPeter Hoar. In this episode, theFifteenth Doctor (Ncuti Gatwa) fails to rescueBelinda Chandra (Varada Sethu) after she is kidnapped fromEarth and inadvertently gets involved in a war on another planet.
Davies used the script to explore a larger narrative of what he viewed as real-world issues. Pre-production for the episode began in October 2023, with many design aspects based aroundretrofuturism. Filming then occurred in November and December atWolf Studios Wales and inRoath, Cardiff. Post-production continued for some months later. It was released onBBC iPlayer,BBC One, andDisney+ on 12 April 2025.
"The Robot Revolution" was seen by 3.57 million viewers. Reception was mostly positive, with Belinda's characterisation particularly praised, though the episode's themes and use of the supporting cast was the subject of criticism. A novelisation written byUna McCormack was released on 10 July 2025.
On 24 May 2025,Belinda Chandra is captured by robots and taken as their queen to "Missbelindachandra One", a planet orbiting the star "Miss Belinda Chandra", named as such by her ex-boyfriend Alan seventeen years earlier. Belinda verbally blames Alan for her kidnapping on the spaceship.
The "Missbelindachandrakind" are composed ofhumanoids and robots, who coexisted peacefully until the robots took control and some of the humans began to rebel. The robots are controlled by the GreatAI Generator, who plans to merge with Belinda.The Doctor, who had been in pursuit of Belinda, arrived six months before her and has since become the planet's historian. Exploiting a fault that prevents the robots from hearing every ninth word, the Doctor and the rebels rescue Belinda, although several rebels, including their leader Sasha 55, are killed.
The Doctor realises that the robots also possess the same version of Belinda's star-naming certificate but that it is 5,000 years older. How the robots acquired the certificate is left unclear. Belinda allows herself to be captured, asking the robots to spare the rebels. Belinda and the Doctor are taken to the Great AI Generator—revealed to be not AI but rather Alan, who had been captured by the robots ten years earlier after Belinda cast blame on him. Viewing life on Missbelindachandra One as a game, Alan merged himself with the machines and started the war because—as it is revealed—Belinda had broken up with him due to his controlling behaviour.
Using every ninth word, Alan communicates to them that he is in pain. Belinda touches her version of the certificate to Alan's, which causes them to experience all of time simultaneously. The Doctor rescues Belinda while Alan reverts to a sperm and egg, which is cleaned up by a robot.
Now free, the humanoids and robots rebuild their society while the Doctor takes Belinda to hisTARDIS to time-travel. He describes meeting her distant descendant Mundy Flynn.[a] Belinda demands to be taken home. However, the TARDIS is unable to return to 24 May 2025, forcing Belinda to travel with the Doctor until she can return. As the TARDIS dematerialises, debris from several Earth landmarks and the certificate float in space, and a calendar turns to 24 May 2025.
"The Robot Revolution" was written byDoctor WhoshowrunnerRussell T Davies.[1] He initially conceptualised the idea as a one-off story but later reworked it into aseries premiere to serve as a companion introduction.[2] Davies said that the episode was difficult to write because he struggled with turning a joke aboutnaming a star after someone into a full script, and that he also viewed the episode as a wider narrative about the concerns surroundingartificial intelligence in a real-world context.[3]
The episode also explores themes aroundincel culture through a line written by Davies in which Belinda refers to the planet as "Planet of the Incels".[4] Series starVarada Sethu said that conversations about this topic were held among the production team, and she and co-starNcuti Gatwa found addressing it from "a place of compassion" very interesting".[4][5]
The scene that introduces Belinda's roommates was not included in the original script but added to a rewritten version months after the initial production block had concluded, as Davies ultimately decided to add them because he felt it unrealistic for a young working nurse to be able to afford a large house by herself.[6]
The episode stars Gatwa as thefifteenth incarnation ofThe Doctor and introduces Sethu as hiscompanion, Belinda Chandra.[7] Sethu had previously played a separate character, Mundy Flynn, in thefourteenth series episode "Boom" (2024).[8] Mundy, it is revealed in "The Robot Revolution", is a distant descendant of Belinda.[9]Anita Dobson reprised her role as Mrs. Flood, an enigmatic character who was first introduced in "The Church on Ruby Road" (2023) and reappeared in the previous series.[10] Alan Budd (the episode's antagonist) was portrayed by Jonny Green, who formerly voiced characters in variousDoctor Who andTorchwood audio dramas.
Other members of the guest cast includedMax Parker, Jeff Kunjumon, Evelyn Miller, and Caleb Hughes, playing the characters of Manny, Stefan, Sasha, and Scoley, respectively.[11] Two of the robots were manoeuvred by puppeteers Stephen Love and Robert Strange, who had previously held similar responsibilities as Wrarth Warriors in "The Star Beast" (2023), Strange doing the same for theBogeyman costume in the 2024 episode "Space Babies".[2]
Set design began atWolf Studios Wales in October 2023. Production designer Phil Sims said he and Davies took inspiration from Americanscience fiction filmsForbidden Planet andThis Island Earth when conceiving the sets. The sets were created with aretrofuturistic appearance influenced by the 1950s. The special effects company Millennium FX designed the larger robot costumes over the course of eight weeks. The costumes were first created digitally and split into 34 different pieces for3D printing, then assembled with glue and finished withsilicon andfibreglass.[2][3]
The polishing robot in the episode responsible for cleaning, dubbedScoot by the production team, was constructed with a similar 1950s aesthetic, primarily based on cars and home appliances of the time period. Michael van Kesteren, the episode's prop designer, specifically named theChevrolet Bel Air andFiat 500 as examples of vehicles. The robot was also based on several different characters, such asWALL-E,Johnny 5,R2-D2, and other associated characters.[12][13]
Scoot was given uniqueomni wheels that allowed it to move laterally as well as straight ahead, as the designers wanted the robot to have a unique range of motion compared to other robots of similar size.[13] The robot was also granted a moveable eye and small puppeteered arms in order to convey more emotion. Due to the prop's interior mechanics, two versions of it were produced: one that could pass freely around the set, the other for the actors to interact with.[12]
The AI Generator was designed to appear large and imposing, with the set and art design teams collaborating to determine where Alan would be inside the machine. The set for the throne room, where Belinda is initially brought in the episode, was re-used for the set that had contained AI Generator's room on Stage 3 atWolf Studios Wales.[2] The design team placed the "head" of the Generator's design just below the centerpiece of the room in order to create the illusion that the room acted like a crown for the Generator and that the room was an extension of him.[13]
The episode, directed byPeter Hoar,[14] was recorded in the second filming block of Series 15 along with the fourth episode "Lucky Day".[15][16]Location filming occurred in November 2023 inRoath, Cardiff, whilesoundstage filming also took place atWolf Studios Wales in December 2023.[2]Principal photography was completed by the end of December.[17]
The episode's original opening moments would have featured Belinda's family, but Davies decided to cut this scene as he felt that "a story about Belinda having a star named after her should start with Belinda having the star named after her".[6]Pick-up andcutaway shots introducing her roommates were recorded while a later episode was in production. A hallway with a doorway were constructed for these, with Davies saying he "had to be careful and kind to the budget".[6]

On thereview aggregator websiteRotten Tomatoes, 100% of 15 critics' reviews are positive, with an average rating of 6.80/10.[18] Will Salmon withGamesRadar+ highlighted the setting and design of the episode, but criticised it for being "light" in plot and weight and for confusing plot points toward its end.[23] Writing forDen of Geek, Stefan Mohamed highlighted the Doctor's characterisation and the episode's new visual and directorial techniques, but criticised Sasha 55's death as a weak narrative moment, as also Alan's antagonistic role.[38]Yahoo! Entertainment's Roxy Simmons thought the episode enjoyable but found it made very little impact on the audience. He also considered its social commentary unsubtle.[39]
The Independent author Ed Power praised the Doctor's characterisation and the episode's fun nature, but felt that elements of Alan's characterisation as a "nerdy" character would receive negative reception and that Sasha 55's death was unnecessary for the plot.[27]IGN critic Robert Anderson criticised the episode for feeling "shallow". He also disliked the plot twist of Alan being the AI Generator.[26] Reviewing the episode forThe Guardian, Jack Seale highlighted the episode's re-introduction of the Doctor's character and the inclusion of topical issues, but criticised the twists involving the AI Generator as well as the execution of the episode's message.[24] Michael Hogan, penning a review forThe Daily Telegraph, wrote that some of the episode's social commentary regarding gender andartificial intelligence were not well executed and felt jarring given the episode's time slot.[21]Mashable's Chris Taylor, in a negative review, commented that as far as the social commentary of the episode, it moved too fast to properly critique any particular aspect.[40]
Belinda's characterisation was the subject of significant discussion in reviews of the episode. Salmon, in his review, stated that unlike the Doctor's prior companionRuby Sunday, Belinda was able to provide a strong contrast to his characterisation as she was "tough and a straight talker" while kind and likeable like Ruby.[23] Other writers concurred, highlighting Belinda's dynamic with the Doctor as a strong point in the episode that indicated promise for her character as the season progressed.[26][21][28][22] Simmons also found Belinda a likeable character, though opined that some viewers might connect immediately with her less easily due to her characterisation.[39] Taylor, in contrast to other reviewers, argued that Belinda's characterisation was weak, and that she lacked a sense of purpose compared to other past companions of the Doctor.[40] Stefan Mohamed praised the episode and performances but criticised some aspects of the writing, calling Sasha 55 an unnecessary character and felt the Doctor's grief over her death to be comical, and felt Alan to be a weak villain, even criticizing Belinda's treatment.[41] Adi Tantimedh fromBleeding Cool gave the episode a 7/10, also panning Sasha's death and the use of Alan as a villain, but ultimately felt the episode to be " a solid, if not sensational, start".[42]
