Production code: 7P
Written by Rona Munro. This three-episode serial first aired from November 22 to December 6, 1989.
After adventuring throughout time and space, Ace finally asks the Doctor to take a visit to her hometown — Perivale.note As it turns out, not much is the same since Ace left the town originally and many of her friends have just up and left. The Doctor, however, takes a curious interest in a black cat that seems to be following them around, and while he tries to set a trap for it Ace finds herself poking around a playground when an anthropomorphic cheetah-person riding a horse chases her around the park. Not long after this scene, the Doctor and Ace are whipped away to an exotic alien planet where the Cheetah people come from — and where Ace's friends and a few other people have been whipped away to. The Doctor is then escorted to the Cheetah people's leader... the Master. And this time, he's acting very darkly. That's what happens when you're allowed to cut loose for the final episode and portray the character as you originally intended without a heaping helping of Camp thrown in to belay complaints that the show is getting too violent for its britches, since, by now, it really doesn't matter, does it?
As it turns out, the planet is some sort of living entity (maybe?) that is slowly infecting the people on the planet with an urge to fight, kill and destroy one another. The Master has already been infected, sporting some neat cat eye contacts, and simply desires to leave the planet. Meanwhile, Ace and her friends are hunted by the Cheetah people and do their best to simply run away. The Doctor and Ace finally meet up again just in time for the Cheetah people to pull an ambush and kill an extra — but not before Midge kills one of the Cheetah people and turns more and more feral.
Separated from the Doctor, Ace meets one of the Cheetah people and kinda befriends her. As it turns out, Ace is also slowly starting to fall to the spell of the planet and is now also sporting those neat contacts. Meanwhile, the Master uses Midge to escape from the planet back to Perivale. The Doctor also uses Ace, after warning her of possible consequences that don't apply to her as she's a main character, to get everyone back home. Waiting for them is the Master, who has taken the time between the two groups arriving to harness the power of a male youth group to challenge the Doctor to motorcycle-jousting.
Either way, the Doctor and the dreaded feral Midge drive at one another and randomly blow up their bikes. The Doctor survives without a scratch while Midge suffers a Critical Existence Failure and dies. Suddenly, the youth group advances on Ace, until that Cheetah person from earlier shows up and tries to chase off the Master. By hugging him. Of course, the Master kills her and meanders off to go steal the TARDIS. There, he encounters the Doctor — and then drags the Doctor back to the now-collapsing-for-some-reason planet where they fight it out in hand-to-hand combat. The Doctor himself sports those adjusted eyes until he realizes that the fighting is killing the planet and that the only way to win is to not fight. The Doctor is whisked away back to Earth and the Master is supposedly left for dead.
Ace mourns the loss of her newfound friend, while the Doctor comes up behind her. Ace takes a few moments to collect herself before saying it's time they go home — back to the TARDIS. The Doctor gives a wonderful monologue as they walk off into the distance, and Ace and the Doctor then go on to have many more adventures... but sadly, for the viewers, this would be the end, after twenty-six years and 155 complete stories...
The Master makes one last appearance, and this time Anthony Ainley was finally allowed to play the character in the more understated way that he had longed for since 1981. Ace is also extremely well developed for an old-series companion, culminating the final part of her three part story arc and serving as the basic template for the characterization and portrayal of most companions in the revival series (which itself owes damn near everything about it to this season and the previous one).
According to the writing team at the time, they were putting together scripts for a "Season 27", intended to air in the second half of 1990, when the axe fellnote . Season 27 would have seen Ace's departure to study to become a Time Lord at Prydon Academy on Gallifrey, the introduction of a new Classy Cat-Burglar companion, and the Seventh Doctor's regenerationnote . Had this season been finished and aired, it would've made Sylvester McCoy the first actor to play the Doctor for more than three seasons since Tom Baker, albeit with much shorter seasons than was the case for the majority of the Classic era.
Following Big Finish's adaptations of the "lost" 1986 season, in 2011 they adapted the stories from Season 27. Two other stories would be adapted into the Seventh Doctor novel The Pit in 1993 and the Sixth Doctor audio play The Rani Elite in 2014. The remaining two stories, "Avatar" and "A School for Glory", remain unadapted to this day (though the latter did seem to at least partly influence the Seventh Doctor novel Human Nature and its later adaptation in the revived series, starring the Tenth Doctor).
Doctor Who was pulled off the air following this episode, would not officially return until the 1996 movie, and would not return as a regularly-airing television series until the start of the revival series in 2005. Although the BBC's studios for the series were officially shut down in 1990 and everyone knew the series was, in effect, cancelled, the BBC repeatedly insisted that it was simply a hiatus and that the show would return to television in the future. Technically it did, and the BBC did repeatedly try to revive the series as a theatrical film first in the late '90s (which, incidentally, is the reason why the revival series began so belatedly), but for all intents and purposes the 16-year "Wilderness Years" era is seen by fans and the general public as the show having been cancelled.
The thirtieth-anniversary Children in Need special "Dimensions in Time" aired in 1993, but this is generally regarded as non-canonical (worth noting though is that a proper canonical Milestone Celebration special was planned for 1993, but various pre-production difficulties led it to be replaced with the much-maligned "Dimensions in Time").
As for Rona Munro, with this serial she became only the third woman to be credited as scriptwriter on the series, after Barbara Clegg for "Enlightenment" and Jane Baker for four stories co-written with her husband Pip.note She would eventually return to Doctor Who to write the Twelfth Doctor story "The Eaters of Light", making her the first writer to contribute to both the Classic Series and the Revival Series (and in all likelihood the only one, given that most of the other Classic Series writers were either retired or dead by the time "The Eaters of Light" aired).
Unfortunately, Ace's adventures with the Doctor up to her eventual departure, plus the full extent of the Seventh Doctor's darkened personality are not depicted, leaving the viewer to scratch their head or make a dash for the Seventh Doctor novels that fill in the holes.
- Actual Pacifist: A very rare Who story to endorse absolute pacifism, as opposed to the usual Martial or Technical kinds.
- An Aesop: This story skewers the "kill or be killed" ethos of the '80s, as personified by Sgt. Paterson and the Master. The Doctor retorts by reminding them both of the Prisoner's Dilemma.
- Alien Sky: The unnamed alien planet has a pink sky.
- And the Adventure Continues: The story — and the original run of Doctor Who — ends with the Doctor and Ace happily walking back to the TARDIS to continue their adventures, with a monologue from the Doctor (added by the script editor when he and the producer realised this was highly likely to be the last episode for at least a while, and possibly ever) to reinforce this.note
- And Then John Was a Zombie: Part Two closes with the reveal that Ace has started to become a Cheetah person. The Doctor comes close as well during his final battle with the Master in Part Three, but is ultimately cured and brought home by rejecting violence.
- Arc Words: "Good hunting."
- Arch-Enemy: The Doctor and the Master spend a moment discussing their role as this before the climactic battle, when the Doctor catches the Master trying to break into his TARDIS after believing the Doctor to have been killed:
- Arson, Murder, and Jaywalking: "Somewhere there's danger. Somewhere there's injustice, and somewhere else the tea is getting cold."
- Ascended Fridge Horror: While it would not be fully explored until the new series, the concept of what happens to a companion's life when they leave it behind is brought up briefly; when Ace returns home she has been placed on the missing persons list and believed to be dead.
- Attention Deficit... Ooh, Shiny!: Invoked. And justified — they're cats and cats adore shiny things.
- BBC Quarry: Appropriate lighting and decent use of scenery makes this a lot more subtle. Sylvester McCoy actually called this a 5-star quarry at one point.
- Back for the Finale: The Master, having not been seen for three years, returns to face the Doctor again. This is the final classic story, but far from the last time they'll meet.
- Big Bad: The Master.
- Book Ends:
- With "An Unearthly Child"—the classic series' first story and final story both feature characters abducted from contemporary suburbia to a brutally primitive environment. Likewise, in "An Unearthly Child" the Doctor attempts to bash a caveman's head in, only to be stopped by Ian. At the end of this serial, the Doctor is about to bash the Master's head in, but is stopped by himself.
- This serial and "Rose" also form this for the wilderness years of Doctor Who as a whole (if we count the TV movie as part of the wilderness era). Both serials involve the Doctor and his companion, a council estate girl, investigating aliens that are infiltrating contemporary London and assorted mysterious goings-on surrounding them, all of which involve an old enemy of the Doctor.
- The Cameo: British comedic duo Hale and Pace show up as shopkeepers.
- Cat Folk: Played surprisingly straight with the Cheetah people in that they're more Cheetah than man, though the original intention was just the opposite.
- Cats Are Mean: The Doctor faces his final and greatest foe yet: Cheetah yuppies from outer space.
- Caught in a Snare: Ace and her gang set a snare to catch one of the Cheetah people. Unfortunately, the next people to pass that way are the Doctor and Sergeant Patterson.
- Circling Monologue: The part-cheetah Master stalks around the Doctor.
- Costume Evolution: For his final appearance in the Classic Series, the Master trades out the black velvet baroque outfit he'd had since "The Keeper of Traken" in favour of a new getup inspired by contemporary yuppie fashion. His new costume consists of a black suit with a serrated silver collar on the jacket, a black belt around his waist with a stylized draconian buckle, a blue ribbon with a sun medallion around his neck, and a pair of leather gloves.
- Drill Sergeant Nasty: "Sergeant" Paterson, the overzealous neighbourhood watchman. His American equivalent would be the Guardian Angel vigilantes, except affiliated to the police.
- Disney Death: The Doctor has a head-on collision on a motorbike with Midge, resulting in a huge explosion that kills Midge. Ace begins to mourn his death after she finds his hat and his umbrella laying on the ground. We soon after find out he's somehow just ended up face first in a pile of rubbish with his backside in the air.
- Dying Vocal Change: Karra normally speaks in an electronically-distorted voice, making her sound more animalistic; after being fatally stabbed in the chest by the Master, she reverts to her original human form and her voice changes accordingly as she dies.
- Don't Explain the Joke: A shopkeeper fails to understand the joke his friend is telling him, about two friends confronted by a lion, and the Doctor explains:He doesn't have to outrun the lion, only his friend. Then the lion catches up with his friend and eats him. The strong survive, the weak are killed — the law of the jungle! Yes, very clever, if you don't mind losing your friend. But what happens when the next lion turns up?
- Drill the Lock: The Master attempts to break into the TARDIS by drilling out the lock.
- Dying as Yourself: As she dies, Karra reverts to her human form and has time for a final word with Ace.
- Empathic Environment: The violence of the Cheetah people is literally causing their world to break apart.
- End of an Era: Moreso than any other story in Doctor Who history. This was the final story of Classic Who; it was the last canon story to be broadcast for seven years, and the last story to be broadcast as part of an ongoing series for sixteen years. Even when the show did eventually return, it would look and feel very different, meaning this story marked the end of an era in many different ways:
- This was the last story to feature Seventh Doctor Sylvester McCoy as the "main" Doctor; McCoy would briefly return at the start of the The TV Movie to regenerate into Paul McGann.
- This was the last story to feature Sophie Aldred as companion Ace; she would be the only Doctor Who companion to never get an explained departure, as the The TV Movie began with the Seventh Doctor travelling alone with no explanation of what had happened to Ace. We would eventually learn her fate over 30 years later in "The Power of the Doctor", but with only a vague explanation for how she and the Doctor parted company.
- This was the final story to be produced by John Nathan-Turner, the longest serving producer in the show's history who had been at the helm since "The Leisure Hive" in 1980, spanning nine seasons and four Doctors. Nathan-Turner formally resigned from the position in 1990, concurrently with the shutdown of the show's production studios.
- This was the last story to be script-edited by Andrew Cartmel, who had been in the post for the last three seasons of Classic Who, coinciding exactly with Sylvester McCoy's tenure at the Doctor.
- The final Doctor Who story to consist of 25-minute episodes, which had been the standard format of the show for almost its entire history up to that point, barring Season 22 (45-minute episodes) and a couple of another anomalies. From the 2005 revival onwards, 45-minute episodes would become the standard length, with occasional longer episodes but never shorter episodes, aside from the occasional "mini-episode".
- The final Doctor Who story to be shot on video; it had been the primary method of recording the show for the entire classic era; for the first 22 seasons it was Video Inside, Film Outside (except "Spearhead from Space", which was shot entirely on film) and the last four seasons were shot exclusively on videotape. The The TV Movie was shot on film, while the 2005 revival would see the show move to using digital cameras, with the footage then processed to resemble film.
- Evil Is Petty: The Master apparently goes out of his way to kill the cat of a child he never met before, because he is a horrible person.
- Fang Thpeak: The Master with his new fangs as result of the Cheetah Virus.
- Faux Affably Evil: This version of the Master is much less the cackling madman viewers had come to expect. In previous stories, Ainley had been told to amp up the ham by production staff, but here was finally allowed to give a much more restrained, brooding and ultimately rather vicious portrayal.
- Fighting in the Playground: There's a chase scene through a playground, with the quarry going over and through the rides in an attempt to shake off the pursuer.
- Fisher Kingdom: Cheetah World
- For the Evulz: The Master's motivation in this episode, apart from saving his own skin from the Cheetah Planet.
- Gadget Watches: The Doctor has a fob watchnote , which he uses to discover the safest nearby part of the planet.
- Grand Finale: To the Doctor vs the Master story arc for the Original Series. Also, the finale for the classic series and almost the entire mythos as a whole, had the fans not kept the enthusiasm going into the nineties.
- Heal It with Water: Karra, injured, is healed by water that Ace brings her.
- He Who Fights Monsters: Literally, in this case. The Cheetah planet gradually transforms people into Cheetah People the more they indulge in the urge for violence.
- Hellish Pupils: The first stage of Cheetah infection. The Master has it permanently here, and various other characters get brief flashes.
- Homoerotic Subtext: The script and performances are intended to suggest a lesbian subtext developing between Ace and Karra, one of the Cheetah People. One of the reasons that the writer disapproved of the eventual costumes for the Cheetah People was that this was obscured, although many fans still caught on.
- Improbable Infant Survival: Hinted at but ultimately played straight; the Master, through the black cat that summons the Cheetah People, considers kidnapping a group of small children playing in a park to participate in the hunt, but ultimately rejects them as not providing enough sport.
- Irony: Sgt. Patterson, the bullying Territorial Army self-defence instructor who proudly lectures a "survival of the fittest" philosophy, suffers a complete breakdown when actually transported into an environment where he has to put this philosophy into practice. He spends most of the story as a cowering wreck.
- Killed Off for Real: The Master, again. This time it was supposed to be for really real (largely owing to the series's cancellation), but First Law of Resurrection + Joker Immunity = Like You Would Really Do It and he was back in the following on-screen story.
- Male Sun, Female Moon: According to Rona Munro, she included the scene with the "moon water" healing Karra because the moon, like cats, is associated with femininity.
- Milking the Giant Cow:
- The Doctor's final battle with the Master ends with him tossing his hands in the air and screaming "if we fight like animals, we DIE like animals!" This gets played for comedy immediately afterwards when the Doctor is transported back to Perivale and obliviously repeats the line, bombastic gesticulating and all, in the middle of an empty road.
- And that doesn't even begin to do justice to the outtakes. Legend has it that Sylvester McCoy is still the only actor in England to eat an entire BBC Quarry.
- No-Holds-Barred Beatdown: For the Doctor's final fight with the Master in Classic Who, amplified by the primal urge for violence that the Cheetah Planet awakens.
- Nothing Exciting Ever Happens Here: Ace describes Perivale as such.
- One-Word Title
- Pressure Point: The Doctor briefly paralyses the Sergeant by poking him in the forehead.
- Rearing Horse: The horse the cheetah rides. Note: During filming, the stunt man couldn't get the horse to rear, or do anything else, but the actress playing Karra could. It turned out that the horse hated men.
- Series Fauxnale: When part three finished airing, the general consensus was that the show was over, having been cancelled due to rapidly declining ratings over the course of the past several years. (Notably, at the end of the episode there was no voiceover by the continuity announcer stating the show would return the following year.) The TV movie in 1996 and the show's full-on revival in 2005 changed that notion.
- Sexy Cat Person: Not as much as the writer originally envisaged, but Ace's interactions with the Cheetah People (especially Karra) are heavily played as a sexual awakening.
- Shout-Out: Derek spends the episode in a David Bowie tee shirt; much of it is obscured by his jacket, but the exposed part prominently displays the "BO" from the Let's Dance cover art.
- The Social Darwinist: Deconstructing this trope and the "survival of the fittest" ethos of Social Darwinism is essentially the primary theme of this episode.
- Sunday Is Boring: Ace complains about how boring Sunday is, describing it as "the one day of the week you can't even get a decent television program."
- Supernatural Gold Eyes: People under the malign influence of the Cheetah Planet acquired golden, cat-like eyes. This included the Master and Ace.
- Take That!: Ace asks whether or not U2 are still active after spotting a copy of War at Midge's flat; at the time the serial aired, the band faced a tremendous amount of backlash for their Concert Film and soundtrack album Rattle and Hum, which saw accusations of Small Name, Big Ego on the grounds of them attempting to rank themselves among preestablished music legends. As Achtung Baby was still a couple years off, the general public sentiment at the time was that U2 had committed career suicide, a sentiment reflected in Ace's inquiry.
- Terrifying Pet Store Rat: Vicious alien creatures called Kitlings are played by black cats with hair gel in their fur (when they aren't being portrayed by an animatronic). A behind-the-scenes featurette includes cast and crew complaining about how unprofessional their feline co-stars were.
- Trash Landing: After his game of chicken with Midge, the Doctor lands on an old sofa.
- Turn the Other Cheek: The Cheetah Planet infects its inhabitants with feral instinct and blood lust, which gradually transforms them into humanoid Cheetahs as they continue to indulge in their urges. Having exhausted its population, the planet has become a volcanic desert on the verge of explosion. While the Master succumbs to primal intoxication, the Doctor realises survival to lie in wilful rejection of violence — which teleports him back to the TARDIS in Perivale.
- Uncertain Doom: It's not clear what the Master did to Squeak's mother, since she only says he "made her go away". Ace responds by protesting that he doesn't need to keep the Cheetahs busy anymore: The original script had the Master using kitlings to send people to the Cheetah Planet For the Evulz (with Harvey and Len among his victims), but those scenes weren't filmed, leaving it as an Orphaned Reference.
- Wrap It Up: By the time the final episode was about to air, it was clear that it was going to be the last for at least a while; the closing monologue was first included in a script dated several weeks before the cancellation was official, but it's clearly meant as a goodbye. (Some confusion about the timing ensued from the need to re-record the audio after airplane noise ruined the original.)
- You Can't Go Home Again: While Ace visits her hometown in this story, it's not the same as she left it. And after giving into her cheetah transformation enough to bring her friends/prey back to Earth she determines that the TARDIS is her home now — a sentiment she restates at the end.
