The Invasion (TV story)

The Invasion was the third story of season 6 of Doctor Who. It featured the Cybermen in what became their established form until Earthshock in 1982.

The Invasion also featured the second appearance of Alistair Gordon Lethbridge-Stewart, now promoted to the rank which became his best known title - Brigadier. It additionally introduced the organisation known as UNIT, as well as the character of Corporal (later Sergeant) John Benton. Behind the scenes, it was the start of Terrance Dicks' record-setting tenure as script editor. Furthermore, it was the final major appearance of the Cybermen until Revenge of the Cybermen in 1975.

Synopsis
The Doctor, Jamie and Zoe return to Earth and become embroiled in the schemes of Tobias Vaughn. They meet up with an old friend, Colonel (now Brigadier) Lethbridge-Stewart, and some old enemies, the Cybermen.

Episode one
The TARDIS materialises in space over the dark side of Earth's Moon, and is promptly fired upon by a missile from an unknown spaceship. The Doctor rushes to affect an emergency relocation out of the missile's path. After rematerialising, the Doctor, Jamie and Zoe find they have arrived in the late 20th century just outside London. The TARDIS' visual stabiliser circuit has become damaged, rendering the ship invisible.

In order to have the circuit repaired, they set out to find Professor Travers and ask for his assistance. A driver offers them a lift to London. A security guard on a motorbike follows in the distance. The driver alerts the travellers of the danger. They get clear of the area and hide in some bushes while the driver explains that passes are required to get in and out of International Electromatics. He himself got in alright, but getting out might just be a bit more difficult. He tells them of the company International Electromatics. The driver tells them that IE have set up factories and houses, all of the local people have been bought out, and most of them join the company, while others have vanished. Once the coast is clear, they return to the truck.

At the guard post, two security guards note the truck driving towards the entrance. The truck stops at the post and the driver shows the guard his pass. The guard looks at him and then hands it back to the driver. The truck continues, but once it is a couple of yards away, the driver soon realises there is another problem. A motorbike stops at the guard post entrance. In the distance, the driver stops the truck, opens the back and the Doctor, Jamie and Zoe get out of it. The security guards arrive on the scene, and one of them tells the driver that he will have to come back with them for questioning. The driver refuses to return to the compound with them, telling them there is nothing they can do to make him. The guards pull out their guns, there is a sudden gunshot, then a second one. The driver collapses. Once the third shot has been fired, there is a silence — the driver is dead.

Meanwhile, the Doctor and his companions get another lift from a car driver. When they arrive at the professor's home, they find that he has left for America, leaving his home in the care of Isobel Watkins and her uncle, Professor Watkins. She explains that the professor has disappeared, after he worked on an invention for International Electromatics. The Doctor and Jamie go to IE's head office in London to investigate. When the computerised receptionist won't let them past, they seek out another point of entry. They fall unconscious after being gassed, and are taken by security chief Packer to see IE's Managing Director, Tobias Vaughn. Vaughn apologises for the rough treatment they have endured. He explains that Professor Watkins was engrossed in a delicate stage of his work, and agreed to remain on site. The Doctor's suspicions are piqued. After they leave, Vaughn opens a hidden panel in the wall of his office, revealing an alien machine.

Episode two
The Doctor and Jamie are abducted by two men, later revealed to be Corporal Benton and Tracy. They are taken to an EC-130H Hercules transporter plane, housing a complete operations room, where they are met by the Brigadier. He explains about UNIT, and the taskforce's investigation of IE.

Concerned about the Doctor and Jamie's failure to return, Zoe and Isobel leave for IE in search for them. They also encounter the receptionist, but, instead of seeking another method of entry like Jamie and the Doctor, Zoe destroys the computer by assigning it an insoluble equation in ALGOL, causing its circuits to overload. Vaughn is watching, and once again opens the hidden panel. A decidedly inhuman voice speaking through the machine tells him that the Doctor and Jamie have been recognised from Planet 14, and are a threat to their plans. Vaughn orders Zoe and Isobel brought to him. Isobel is used to make her uncle, who is being held captive, co-operate.

The Doctor and Jamie return to Travers' house, to find a note from Zoe and Isobel, explaining their going to search for them. They return to IE, and find several packing cases being loaded onto a train. Part of a feather boa Isobel gave to Zoe is hanging out of one of the boxes, alerting the Doctor and Jamie to the fact that their friend is inside. But before they can rescue Zoe and Isobel, the Doctor and Jamie are again captured by Packer.

Episode three
The Doctor and Jamie are taken to Vaughn, where the Doctor accuses him of kidnapping Zoe and Isobel, a claim Vaughn flatly denies. Vaughn invites the two companions to come to the company's country compound, where the train will be arriving; it is here they meet Professor Watkins, who has been warned to not mention Zoe and Isobel's whereabouts. He shows the Doctor his cerebration mentor, a teaching device that is capable of inducing emotional changes.

The Doctor queries Vaughn of the deep space communicator he noticed when he came into the compound; in return, Vaughn demands that the Doctor explain about the failed circuit, even threatening to hand Zoe to Packer if he doesn't co-operate. They are taken away.

Jamie and the Doctor fool Packer and escape in the elevator. They jam the elevator between the 4th and 5th floors, and decide to leave through the elevator shaft. Packer tries to kill them by sending the elevator to the top, but they escape onto the roof.

The Doctor and Jamie escape onto a railway siding. Whilst in the crates, Jamie has a near encounter with an automated cocoon.

Episode four
The Doctor and Jamie emerge from the crates, and overhear guards being ordered to take Zoe and Isobel to the tenth floor.

Vaughn confides in Packer that he intends to use the cerebration mentor to control the Cybermen once they have invaded Earth; he also intends to use the TARDIS as a "getaway car", should he fail.

Vaughn broadcasts over the intercom system to the Doctor that he has ten minutes to surrender or Zoe will be harmed. Using a communicator given him by the Brigadier, the Doctor calls for assistance from UNIT, who assist in rescuing Zoe and Isobel from the room in which they are locked. Realising how dangerous UNIT are to his plans, Vaughn exercises hypnotic control over Major General Rutlidge, and orders him to cease UNIT's investigations.

The Doctor examines photographs of UFOs over the IE factory, and reasons that those ships are bringing cocoons to Earth. He, along with Jamie, sneak into the London IE warehouse, where they witness the emergence of a Cyberman from its cocoon.

Episode five
After witnessing the reactivation of the Cyberman, the Doctor and Jamie sneak back out of the IE warehouse. They return to UNIT HQ and warn the Brigadier that a Cyberman army is invading Earth, and that they are hidden somewhere in London. However, Rutlidge has ordered the Brigadier to cease all investigations against IE. Lethbridge-Stewart intends to gain authority from Geneva, but requires proof to back his reasoning. Isobel offers her expertise as a photographer, but the Brigadier refuses.

Vaughn tests Watkins' device on an awakened Cyberman; however, the alien is driven mad by the machine and escapes into the sewers. Vaughn reveals that in an hour's time the Earth will come under the control of the Cybermen through a micromonolithic circuit built into every IE device; the Doctor discovers this same circuit when he opens up an IE radio, and sets about making a device to block the telepathic signal.

Meanwhile, Isobel, Zoe and Jamie have ventured into the sewers to obtain proof of the Cybermen's presence on Earth. There they find the body of a policeman, who had followed them into the sewers and was subsequently killed by the Cybermen. They then encounter the insane Cyberman, who begins menacingly approaching the intrepid trio.

Episode six
Isobel, Zoe, and Jamie narrowly escape from the sewers, and several of the Cybermen are killed by UNIT troops. Isobel has managed to snap some photos of the Cyberman. The photos, however, prove to be worthless as they look too much like fakes.

Watkins perfects his machine and delivers it to Vaughn, but discovers that the Managing Director has been partially cyber-converted, which protects him from bullets. UNIT manage to free Watkins from IE, during which time the Doctor creates a neuristor, which neutralises the Cybermens' hypnotic signals. The Brigadier orders the troops to have one of these taped to the back of their necks.

At dawn, the signal is broadcast, causing people around the world to collapse unconscious. The Doctor's polariser has fallen off and he begins to blank out, leaving the Cybermen able to take over London.

Episode seven
The Doctor is given a new polariser, and he and UNIT assess the situation, knowing the spaceship that the transmissions are coming from is on the Moon. UNIT decides to use a Russian rocket to destroy the source of Vaughn's signal, while using UK missiles to destroy the incoming Cyberfleet. The Doctor heads off to talk to Vaughn. Captain Turner is sent to Russia to organise the rocket, while the Brigadier goes to the Henlow Downs missile site.

The Doctor stays behind to try to persuade Vaughn one last time to help his people. The missiles are successfully launched, with help from Zoe, and the Cybermen blame Vaughn for the setback in their plans, announcing that they will use a megatron bomb to destroy life on Earth.

Episode eight
A furious Vaughn uses the cerebration mentor to destroy the machine in his office. The Doctor persuades Vaughn to now aid humanity instead of trying to defeat it, and they take a helicopter to the factory, where they use Watkins' machine to battle the massed army of Cybermen; UNIT forces arrive later to assist. Vaughn is killed in the skirmish, but the homing signal is successfully shut down.

The megatron bomb is destroyed by a missile, while the rocket destroys the last Cyberman ship, consequently stopping the hypnotic signal. With the crisis now over, and the visual stabiliser circuits now repaired, the Doctor, Zoe and Jamie depart in the TARDIS.

Species

 * There are cows in the field where the TARDIS lands.
 * Jamie mentions the Yeti to the Brigadier.

 * ALGOL is a language understood by computers.
 * The visual stabiliser circuit controls the TARDIS' outward appearance; removing it renders it invisible.

Astronomical objects

 * The Cybermen have a spaceship hidden behind the dark side of the Moon.
 * The Cybermen mention encountering the Doctor on Planet 14.

Production

 * Dialogue places this story four years after the events of The Web of Fear. This story is also placed "some months" before Spearhead from Space, according to dialogue in that story.


 * This story had a working title of Return of the Cybermen, which was later changed to The Invasion to keep the Cybermen's reappearance a surprise until episode four. It was originally conceived as a four-part story and got expanded to eight when the next story, The Dreamspinner, fell through.
 * This story marked the debut of Terrance Dicks as Script Editor and his first credited contribution to the series. Dicks would go on to write or co-write a number of episodes, and become best known for his work of writing novelisations for Target Books and eventually contributing to most lines of original fiction based upon the series on into 2008.
 * Together with The Web of Fear, this story was a sort of "test run" for a format switch. For the next two or three seasons, most stories would feature the Doctor working with UNIT to protect humanity on more-or-less modern-day Earth.
 * While the Cybermen would continue to change their appearance on the series, as they had done since their introduction, this story set the basic design for them, first developed for this story by Bobi Bartlett, through the 1980s. Cybermen emerging from cocoons was also used in Earthshock. They also operate in the London sewers in Attack of the Cybermen. A mass invasion of London by Cybermen also features in the Series 2 stories, Rise of the Cybermen, The Age of Steel, Army of Ghosts and Doomsday, and in the Doctor Who Magazine comic The Flood.
 * Cybermats were to have appeared in this story.
 * It was during filming of this story that Frazer Hines announced his intention to leave the series.
 * Zoe makes no appearance in episode three of the story as Wendy Padbury was on holiday during the week when it was recorded. Similarly, Jamie appears only in a pre-filmed insert in episode eight as Frazer Hines was due for a break.
 * A black and white shot of a Cyberman, with two others behind, walking down the steps of St. Peter's Hill, with St. Paul's Cathedral in the background, accompanied the Radio Times programme listing for episode one, bearing the title Invasion and with the accompanying caption "Dr. Who starts a new adventure today at 5.15 — one that will bring him face to face with some of his deadliest enemies, the Cybermen".
 * The following piece of behind-the-scenes information appeared at the foot of the Radio Times programme listing for episode five: "For this Dr. Who story more filming was done on location than ever before, and the production team were fortunate to have the co-operation of both the Army and Air Force on scenes that involved such equipment as jeeps, a transporter plane, a three-ton lorry, and a rescue helicopter."
 * Nicholas Courtney reprises his role as Lethbridge-Stewart, now promoted from Colonel to Brigadier, from The Web of Fear.
 * John Levene (Benton) previously appeared as a Cyberman in The Moonbase and as a Yeti in The Web of Fear. He was initially contracted to play a Cyberman in The Invasion, but landed the role of Benton after the actor originally cast – who shall remain nameless – was fired by Douglas Camfield for continually turning up late for filming, causing the planned shooting schedules to be changed.
 * John Levene (Benton) was uncredited on-screen for episode five, but was credited in Radio Times.
 * Peter Halliday also provided, uncredited, the voices of the Cybermen in episodes six to eight and of the Cyber Director — hidden in a concealed compartment in Vaughn's office — in episodes two and five to eight.
 * Norman Hartley (Sergeant Peters) was credited as "Sergeant" in Radio Times for episode eight.
 * The actors playing the Cybermen were credited on-screen, but not in Radio Times.
 * In the DVD's animated version of episode one, the words "Bad Wolf" (the story arc of the 2005 series) are written on Isobel's wall as an in-joke.
 * Also in the animated episode one, the car that the Doctor, Jamie and Zoe hitch a ride with after the lorry driver is shot has the licence plate H 23 63, which is a reference to the date of the original broadcast of An Unearthly Child, the very first episode of Doctor Who, on 23 November 1963.
 * Additionally, the animators got Zoe's costume wrong; for the beginning part of the missing episode one, Zoe would have worn her catsuit from The Mind Robber and she would have changed when Isobel got her fixed up with "some proper gear".
 * The episode was intended to prove that Earth-based stories could be produced cheaply and effectively. Ironically, it was the most expensive Doctor Who episode ever produced when made, and remained so for several years.
 * Originally, Professor Travers and his daughter Anne were to appear, but were replaced by Isobel and her uncle when Mervyn Haisman and Henry Lincoln refused to grant the rights. The DVD's production subtitles claim they were granted rights to the characters, but as the characters became less involved in the story, they thought it was not worth including them. The characters are mentioned in dialogue, however: Isobel lives in Travers' former house in London, and Professor Watkins mentions that Travers was getting "past it," so he persuaded him to live in America with Anne.
 * The prologue of PROSE: Iceberg opens during the Cybermen invasion in this story. The Cybermen in that novel are said to be from Planet 14, which was first mentioned in The Invasion by the Cyber-Planner. COMIC: The World Shapers also picks up on the Planet 14 reference, though it explains it away in a very different way. Since The Invasion takes place in either in the late 1960s or 1970s (see UNIT dating controversy) and no other televised Cybermen story had taken place prior to 1986 (the date of The Tenth Planet), the Doctor must have met the Cybermen before in an untelevised story. The Cybermen did have access to time travel technology, so that conclusion is not an absolute certainty. In 1986, the Cybermen on Mondas appeared to be of a less sophisticated design and did not give any indication of having a fleet of ships. The Cybermen in the 1970s seem to be more advanced and do have a fleet of ships.

Influences

 * The influence of the various spy thriller films and television shows which were popular at this time are very clear. Tobias Vaughn is similar to the supervillains featured in the James Bond films and The Avengers. The Doctor acting as advisor to a military group dealing with an otherworldly menace is highly reminiscent of the Quatermass serials. Specifically, the plot of The Invasion has some similarity to , though not as much as some other Doctor Who stories, such as Spearhead from Space.

Filming locations

 * The cow pasture in which the TARDIS materialises was located at Williamstrip Farm at Coln St Aldwyns. Professor Watkins' house was located at St James' Gardens in Kensington.
 * Kingston Minerals in Kempsford served as the IE compound, while the compound's roof was actually that of the Associated British Malsters' Guinness factory in Wallingford, Oxfordshire.
 * Additional scenes at IE were filmed at the Guinness Factory in London.
 * The canoe sequence was filmed at Lisson Grove and the helicopter sequence at Denham Aerodrome in Buckinghamshire.
 * Other scenes were filmed at various locations in Gloucestershire.
 * Ealing Television Film Studios, Ealing Green, Ealing
 * Lime Grove Studios (Studio D), Lime Grove, London

Production errors

 * In episode five, the panel concealing the Cyber Director struggles to close.
 * The Cyberman falling from the roof of an IE building in episode eight is clearly an empty costume.
 * In episode eight, the strings that make the Cyber Director's "head" twist are clearly visible.
 * In episode four, the Doctor and his companions claim to have seen a ship on the moon — when they didn't. (In the DVD's animated episode one, a ship was added to cover this up.)
 * The Cybermen wear silver painted tennis shoes.
 * In episode eight, Wendy Padbury fluffs her line regarding the distance to the Cyber Ship, quickly correcting "30—" to say "50,000 miles."
 * Throughout, Brigadier Lethbridge-Stewart's moustache changes size and shape.
 * Some episodes of the story were broadcast in such an amplitude that sometimes makes it hard to make out what the cast were saying.

Continuity

 * Tobias Vaughn returns in PROSE: Original Sin, in which it is revealed that not only did he survive by transferring his mind into a cybernetic body, but funded the development of BOSS, Operation Golden Age, and Professor J.P. Kettlewell's robot, and influenced the expansion and policies of the Earth Empire.
 * At this point, the Cybermen are aware of the TARDIS ("he has a machine"), but make no reference to its nature or that he is a Time Lord.
 * Isobel's photographs of the Cyberman invasion were later derided as fakes and she became a standing joke on Fleet Street. The journalist James Stevens was highly dubious of her claims that the Earth had been invaded by "robot men from outer space." She was threatened by a man with a lisp and her boyfriend left her as his career was at risk because of their relationship. (PROSE: Who Killed Kennedy) However, her boyfriend was not Jimmy Turner as they later married. (PROSE: The Scales of Injustice)
 * The Cybermen killed in the conflict are claimed by UNIT and later used to create weapons effective against Cybertechnology (TV: Death in Heaven).
