The Moonbase (TV story)

The Moonbase was the partly-missing sixth story of Season 4 of Doctor Who. It saw the reappearance and first redesign of the Cybermen, solidifying their place as one of the series' key villains. This story was the first in Doctor Who history with sequences taking place on Earth's Moon.

Synopsis
The TARDIS arrives in 2070 on the Moon, where a weather control station under the command of a man named Hobson is in the grip of a plague epidemic — in reality the result of an alien poison planted by the Cybermen. Jamie is knocked unconscious and lapses into a delirium, leaving the Second Doctor, Ben, and Polly to fight off a massive Cyberman attack.

Episode one
The TARDIS makes a bumpy landing after the Doctor manages to control it's descent. The travellers observe the scanner and Polly says that they have landed on Mars after all. Ben disagrees and says it must be the Moon. The Doctor agrees. Annoyed that he failed to control the ship he wants to move on straight away but is over ruled by Ben and Polly who want to explore. The Doctor reluctantly agrees and decks them out in space suits.

The travellers explore the surface of the moon. They begin to lark about in the anti-gravity however Jamie over stretches himself and knocks himself out. As the others go to save him they discover his unconscious body being carried away into a Moonbase. They follow and the door opens welcoming them.

Inside the Moonbase a staff of workers are operating a series of consoles. One of the workers collapses leaving marks on his face. Hobson, the controller, sends the man to sick bay to join the others who have come down with this virus - who include the base's doctor. Ben, Polly and the doctor are led in. Hobson allows Polly to go and look after Jamie in the sick bay but keeps the Doctor and Ben with him. Hobson explains that the Moonbase is a weather control station that keeps Earth's weather in check. They are using a gravity machine called the gravitron to control the weather. As this is being explained another worker falls ill. The Doctor offers his services. The Moonbase contacts Space Control to inform them who react by quarantining the Moonbase. One of the crew informs Hobson that their latest communication with Space Control was listened in on by someone close to the base.

Down in the Sick Bay Polly is looking after Jamie who is hallucinating about the phantom piper, his clan's variant of the Grim Reaper. The Doctor sends Ben back up to the control room as he needs someone to be keeping an eye on the goings on up there. He does so and is allocated to work with Ralph in the storeroom. Once he gets there he discovers that someone has been stealing food. He is sent to do a job and while he is away Ralph is attacked by a metal hand. By the time Ben returns Ralph's body is gone.

Back in the Sick Bay Polly discovers the Doctor investigating some silver paper. They are interrupted by Dr Evans, the base's previous doctor, wake up and scream something about the silver hand before collapsing dead. The Doctor wonders what he might have meant and goes to report the death to Hobson.

Ben is reporting the disappearance of Ralph to Hobson when the Doctor comes to explain about Dr Evans' death. Hobson refuses to report it to Space Control just yet as they will close his operation today. He goes down with the Doctor to observe the Evans' body.

In the Sick Bay Polly is helping Jamie to drink some water. He wakes up to see a figure behind Polly. She turns and sees it disappear through the door. She screams, alerting the Doctor and others. On exploration there is found to be nothing there. Hobson puts this down to Polly's nerves. Hobson goes over to Dr Evan's bed and finds the body gone. He asks the Doctor if he is playing a sick joke but the Doctor assures he isn't. Hobson is informed of another crew member going down with the virus and leaves telling the Doctor that he will be kicked out if he can't find Evans' body. The Doctor goes to explore whilst Polly leaves to fetch Jamie some water. He awakes to see a Cyberman approaching him - convinced that it is the phantom piper he collapses.

Episode two
Polly witnesses the Cyberman abducting a patient. She informs the Doctor and the others, but Hobson does not believe her due to lack of evidence. Hobson soon notices the Moonbase's radio transmissions are being monitored. More people are infected by the virus and the Cybermen abduct them all. The Doctor soon works out the Cybermen have infected the sugar in the food stores to make the virus spread, thus explaining the virus' seemingly random attack pattern — depending on the crew's preference for sugar in their food or drink. They contact base but the radio transmissions are blocked. The Doctor informs Hobson that the Cybermen are definitely on the Moonbase and asks if the men have searched everywhere. After Hobson informs them they have checked everywhere apart from the medical wing, a Cyberman appears from one of the medical wing beds and advances towards them.

Episode three
Bob, a crew member, is killed. The Cybermen contact the Cyber fleet. The leader reveals the dead crew members have been augmented and are under Cyber control. More Cybermen emerge from hiding and take over central control. They intend to use the gravitron to destroy life on Earth and send Doctor Evans, the first victim, to operate it. Ben, Polly and Jamie (now recovered) use a cocktail of certain types of chemicals, each of which attacks a certain type of plastic, to dissolve the Cybermen's chest units. The fleet land and deploy reinforcements, which advance in force across the lunar surface toward the Moonbase.

Episode four
The Cybermen destroy a relief craft and use radio controlled beams to reactivate the augmented crew members, who walk around the Moonbase killing multiple people. They are soon killed by the crew, but their relief rocket has been thrown into the Sun. The Cyberleader threatens that if the resistance continues they will fire, demonstrating by making the base lose oxygen by punching a hole in it. They use a large cannon to fire shots at the Moonbase, which are deflected by the gravitron. The Doctor aims the gravitron at the surface and the Cybermen and fleet are cast off into space. Hobson repairs the gravitron and the Doctor and his companions slip away. Back aboard the TARDIS, the Doctor decides to consult a device called the time scanner, which can give glimpses of the future. An image of a large crab-like claw then appears on the scanner screen...

References to popular culture

 * Hobson calls the Doctor a "proper Rip Van Winkle".
 * While jumping on the Moon, Polly jokes about Ben having had ballet lessons.
 * Jamie mistakes a Cyberman for a piper phantom of his Scottish culture.

Science

 * The Cybermen shoot a hole in the Moonbase, making it lose oxygen.
 * The Cybermen's chest unit appears to be made of a kind of plastic. Ben and Polly make up a mixture with different solvents (acetone, benzene, ether, alcohol and propane) in order to affect it. Credit for coming up with the idea belongs to Polly.
 * Ben is quite knowledgeable about certain things on the moonbase. He knows that the Gravitron uses thermonuclear power, that interferon is a viral antibody, that acetone is present in nail varnish remover and that the spray from the fire extinguishers (used to contain the nail varnish remover) would evaporate in a vacuum.
 * The Cybermen infect the scientists with the large neurotropic virus named Neurotrope X, visible with the microscope in the medical unit of the base.
 * The scientists would like to call for help through a distress rocket made of sodium, that burns in the sunlight.

TARDIS

 * The Doctor suggestes that the TARDIS is a sterile craft.
 * A chest in the TARDIS provides space suits for the Doctor and his companions.
 * The TARDIS has a time scanner, rarely used by the Doctor, able to give a glimpse of the future.

The Doctor

 * The Doctor mentions that he studied medicine under Lister in Glasgow in 1888.

Story notes

 * This story had the working title Return of the Cybermen.
 * The final clip of the episode leads into The Macra Terror.
 * In an early edit of the script, the Cybermen had names.
 * Talkback from the headphones of the crew on the studio floor is clearly audible at times during episode four (the same problem as had earlier caused the opening episode of The Daleks to have to be remounted) — for example, a voice can be clearly heard saying "Cue" at the start of the scene where the controlled scientists are first activated by the Cybermen.
 * Alan Rowe is credited as 'Voice from Space Control' and 'Dr. Evans' (separate on-screen captions) for episodes one and three, only as 'Voice from Space Control' for episode two and only as 'Dr. Evans' for episode four. He is billed as 'Voice from Space Control/Dr. Evans' in Radio Times for episode three.
 * All of the actors playing the scientists were credited without specific roles under the heading 'Others in Cast' in Radio Times.
 * Mark Heath is credited as 'Ralph' for episode one, and as 'Scientist' for episode three. He is billed without specific role under the heading 'Others in Cast' in Radio Times for episode three.
 * John Wills and Sonnie Willis, playing Cybermen, are credited without specific role under the heading 'Others in Cast' in Radio Times for episode one.
 * Another of the unnamed scientists is played by Victor Pemberton, who went on to write TV: Fury from the Deep and AUDIO Doctor Who and the Pescatons.
 * Episode 3 features a rare sequence in which the viewers actually hear the Doctor's thoughts. Even more unusual -- the Doctor actually replies to his internal monologue.
 * The scene in which the Doctor asks Polly to make coffee is often cited as an example of sexism in Doctor Who. In her comments on the 2014 DVD release, Anneke Wills disputes this, pointing out that Polly is responsible for devising the method used to destroy the Cybermen inside the base. Ironically, while the coffee scene is frequently replayed, another scene in which Ben outright tells Polly that going after the Cybermen "is man's work" is forgotten.
 * According to Anneke Wills, during his initial exploration of the control room set, Patrick Troughton was almost crushed when the gravitron prop fell from its rigging and landed only inches away from him.

Production errors

 * In episode two, when a Cyberman tries to zap Polly while she tends to Jamie in the sick bay, he misses, but she falls anyway.
 * Hobson notes they need to keep a hurricane in the Pacific Ocean. However, the Gravitron is pointed at the Atlantic and the hurricane is threatening Miami.
 * Close-ups of the transparent dome from the outside only show the Gravitron, not any of the desks, controls, people etc.
 * The examination tables in the sick bay are very light and wobble frequently. The most obvious cases are when the Cyberman takes one of the crew off one and later when he hops up off the table, almost knocking it over completely.
 * When Evans sneaks into the Gravitron control room, he puts the cloth helmet on back to front (in the next scene it's the right way round).
 * When the Cybermen's spaceships land, the wires holding them are clearly visible.
 * Due to a mechanical problem during recording of Episode 4 (described in "Story Notes," above), the director's voice can be heard at least once.
 * The Moonbase control room set is noticeably smaller, among other differences, in Episode 4 compared to the other episodes. This is due to the aforementioned need to relocate production of the final episode to another studio. Although the set was rebuilt as close as possible to how it looked in the previous three episodes,. there was no escaping the fact the new studio was physically smaller.

Continuity

 * International Space Command previously appeared in TV: The Tenth Planet.
 * The Cybermen shoot energy from their hands. (TV: The Tomb of the Cybermen and Rise of the Cybermen)
 * The Cybermen would make use of viruses and biological agents in TV: Revenge of the Cybermen.
