The Armageddon Factor (TV story)

The Armageddon Factor was the sixth and final story of Season 16. It concluded the season-long Key to Time story arc. Mary Tamm makes her final appearance as Romana I while her replacement, Lalla Ward, appears in the story in a different role. The Black Guardian appears for the first time and isn't seen again until Mawdryn Undead.

Synopsis
The final segment of the Key to Time is at the heart of a devastating war between neighbouring planets Atrios and Zeos. The Fourth Doctor discovers that a sinister entity is manipulating events and the cost of obtaining the final segment may be more personal than he imagined.

Episode one
The sixth and final segment of the Key to Time is on the planet Atrios. Twin planets Atrios and Zeos are locked in a long-running war. The young Princess Astra, nominal leader of Atrios, is appalled at the devastation, but the Marshal, in charge of the war, actually possesses the power. The Marshal secretly confesses to his aide-de-camp Shapp that they are losing. He is desperate for the edge that will bring victory. On instruction from an unseen entity, he leads Astra on a fool's errand into a trap, where she is abducted and transmatted away.

The Doctor and Romana land on Atrios, and the Doctor's TARDIS is soon buried in rubble from a Zeon aerial bombardment. The Marshal finds them, and believes them to be spies, along with Astra's lover, Merak. The Doctor tricks the Marshal to calling for K9, who knocks out the lights to let them escape. They find the TARDIS gone.

Episode two
Merak has followed them, and they find Astra gone. K9, meanwhile, is lured away to be recycled. The Marshal is told by an unseen force, who tells him to treat the Doctor and Romana as guests. The Marshal implores the Doctor to assist Atrios. The Doctor proposes a shield that will stop the Zeons from attacking, but the Marshall insists he create a weapon for total victory.

Romana notices that the Marshal is acting under an outside influence when he accidentally shows a small device on his neck after flipping out when the Doctor runs to save K9 from the furnace. Afterwards, the Doctor asks the Marshal to send him to Zeos. The Marshal refuses. The Doctor reveals to Romana that something is probably blocking Zeos. Astra appears on a television and states that the Zeons will destroy Atrios if the Marshal does not surrender. The Doctor is trapped by two people in masks in a transmat.

Episode three
The unseen entity tells Marshal that the war will stop, while the entity traps him in his domain. It calls itself the Shadow, who reveals that he has his TARDIS. The Shadow asks the Doctor to open his TARDIS and bring out the other five segements and then leaves. The Doctor decides to search for the sixth segment. Merak, meanwhile, has transmatted to the Zeos. Astra is on the ship in chains, being asked by the Shadow where the sixth segment is. Romana and K9 transmat to Zeos, following Merak.

Shapp finds himself with the Doctor after after being transmatted. K9 finds the commandant of the Zeon forces, which is actually a supercomputer named Mentalis. The Marshal, meanwhile, has decided to attack Zeos. They find that Mentalis has been instructed to conceal any information on Astra. The Marshal prepares to attack Zeos.

Episode four
They learn that if it is destroyed, it will destroy Zeos and Atrios - a concept known as the Armageddon Factor. The computer can't counterattack because it's been told that the war is over. They discover the Marshal, in a last-ditch effort, is piloting the last Atrian warship to destroy the Zeon capital with a nuclear missile. The attack will set the mutual destruction in motion.

Astra is hypnotised by the Shadow and a projection of her lures Merak, and he begins falling. The Doctor is, meanwhile, trying to reinstruct Mentalis, but accidentally triggers the computer into waiting for an attack to blow itself up immediately. The computer becomes mindless by destroying its own control center.

Desperate to stop the Marshal's attack, the Doctor uses the five segments of the Key to Time, plus an artificial sixth segment made from chronodyne, to generate a temporary time loop around the Marshal's ship.

Meanwhile, K9 is hypnotised by a small device which takes the guise of a distress call. K9 is then transported away where he is reprogrammed. The TARDIS heads to the third planet, and the Shadow laughs that the Key to Time is his.

Episode five
The Doctor, Astra and Romana are on the third planet, and each one is separated from the others. The Doctor finds another renegade Time Lord, Drax, in the corridors of the third planet. Drax was employed with threat of death, and he was forced to build Mentalis. The Doctor persuades Drax to assist him, and they remove the control device from K9. Drax repairs his dimensional circuit.

They uncover the ultimate truth: a third party, known as the Shadow, is manipulating the entire war from his enormous vessel midway between the two planets. An agent of the Black Guardian, the Shadow has been watching the final segment of the Key (Princess Astra herself), setting the war in motion and simply waiting while the Doctor risked life and limb to find the first five segments.

Drax enters with the dimensional circuit and shrinks the Doctor down.

Episode six
Drax also shrinks himself, and they decide to have one of them provide a distraction. Romana, meanwhile, realises that Princess Astra is the sixth segment to the Key to Time. Merak transports himself to the third planet. Drax and the Doctor return to normal size and take the Key to Time from the Shadow. Merak stays behind to look for Astra, who has turned into the sixth segment.

When the artificial time loop expires, the Doctor and Drax disarm Mentalis. When the Marshal fires, the war rockets are deflected by a force field, destroying the Shadow and his ship instead.

Astra converts herself into the final segment, completing the Key to Time and giving the Doctor, for the moment, absolute power over the entire Universe. The White Guardian appears on the TARDIS monitor. He demands that the Doctor hand the Key over to him. When he rather callously dismisses Astra's sacrifice, the Doctor realises this is actually the Black Guardian in disguise. The Doctor orders the Key segments to disperse across the Universe, which also allows Astra to reunite with Merak. The Black Guardian is furious and threatens to destroy the Doctor. However, the Doctor has installed a randomiser on the TARDIS console, ensuring that neither he nor the Black Guardian knows where he'll end up next.

Story notes

 * Originally the sixth segment was to be the shadow of the Shadow.
 * This story had the working title of Armageddon.
 * Part one was promoted as the five-hundredth episode of Doctor Who.
 * This story was the final six-part story ever broadcast. Two other stories during the classic series do come close, however. Shada was partially produced for the next season, but never broadcast and when sold internationally, The Two Doctors was broken up from its format of 3 x 45 minute episodes into the more traditional 6 x 25 minute episodes.
 * According to Mary Tamm in the DVD featurette "There's Something About Mary", it was while filming this serial that she made her final decision to leave the series.
 * Twenty-three minutes into transmission of part five, a technical fault on the playback equipment – which occurred at the point where the Doctor is being escorted to the TARDIS by the Mute and the Shadow makes to remove his control device from Princess Astra, saying "Now, Princess, your work is done. Your dest-" – resulted in the programme going off the air for twenty seconds. BBC continuity apologised to viewers for the breakdown in transmission, displaying a TEMPORARY FAULT caption slide and playing music, "Gotcha" by Tom Scott (better known as the theme music to Starsky & Hutch), until the fault was rectified. When transmission was restarted, the 625 line PAL colour videotape had been slightly rewound so that there was a repeat of the action immediately prior to the break, with the Shadow's line finally completed as "Your destiny is at hand."
 * Pat Gorman (Pilot) is uncredited on-screen for part six, but credited in Radio Times.
 * Stephen Calcutt (Mute) is uncredited on-screen for parts five and six, but credited in Radio Times. His character is referred to as 'Super Mute' in existing BBC documentation for the story.
 * It was on the set of The Armageddon Factor that Tom Baker was very angry with some scripts. However, director Michael Hayes got along with Baker.

Outtakes and gag reel footage
Several clips of scene performances not intended for broadcast have been circulated from this serial, including two sequences videotaped during rehearsal (Mary Tamm is seen wearing glasses and hair-curlers). In one scene, Tamm and Baker jokingly pretend to move in for a kiss after delivering a line, and in another widely circulated clip, the Doctor replies to a negative comment from K9, "You never f****** know the answer when it's important!" Off screen crewmembers laughed at both of these outtakes.

It was also during production of The Armageddon Factor that Baker, Tamm and John Leeson filmed a brief one-minute gag scene dubbed "Doug Who?" for the BBC staff Christmas party. The scene begins with the Doctor and Romana sitting on the floor by the TARDIS console, apparently kissing off screen, and then acting tipsy as they share a bottle of vodka with K9, who is asked to sing a few bars of "We Wish You a Merry Christmas". The Doctor then asks K9 what he wants for Christmas; K9 replies and then asks the Doctor for what his desire is, to which the Doctor looks into the camera and then leers at Romana, who leers back before the two actors and the crew break into laughter.

To date, the rehearsal outtakes have not been commercially released, though they are widely available on video-posting websites. "Doug Who?", retitled "Merry Christmas Doctor Who", is included as a bonus feature in the expanded Key to Time DVD set released in 2007 in the UK and 2009 in Region 1.

Myths

 * Theta Sigma is the Doctor's real name. It's implied here and further established in TV: The Happiness Patrol that this is a nickname.
 * The outtake in which Tom Baker barks at K9 "You never f***ing know the answer when it's important" is sometimes described as an outtake from actual filming, and sometimes is used as an illustration of Baker's temperament on the set. In reality — as revealed from an actual viewing of the clip — it was simply a joke that occurred during a taped rehearsal (as evidenced by the fact Mary Tamm is not in full costume, is wearing her off-screen glasses and has her hair up in rollers).
 * Similarly, the rumour that Baker and Tamm filmed an unbroadcast kissing scene also stems from the existence of another rehearsal gag take, as well as the infamous "Doug Who?" skit (described above). Nothing of this sort was filmed for TV broadcast, nor was "Doug Who?" ever intended as part of the televised story either.
 * A longstanding myth holds that Mary Tamm revealed to the production team that she was pregnant and this led to her resignation during or after production of Armageddon Factor. This is openly contradicted by Tamm in interviews and the 2007/09 DVD featurette "There's Something About Mary" in which she states she chose to leave because she was no longer satisfied with the character of Romana and would have returned to film a regeneration if she'd been invited.

Filming locations

 * BBC Television Centre (Studio 3), Shepherd's Bush, London
 * Ealing Television Film Studios, Ealing Green, Ealing

Production errors

 * In part two, after the TARDIS has left, it can still be seen behind Romana just after K9 starts blasting a door.
 * In the same scene, K9's laser beam is not properly aligned because the camera moves slightly.
 * In part three, Shapp's gun falls apart when it hits the floor.
 * In part four, when K9 exits the transmat, he's got the new left panel he gains in part five.
 * In part six, Astra regains the circlet Merak had used to distract the Mute.
 * In part six, one of the Mutes kicks up a piece of studio carpet.
 * In part six, when Drax is sitting next to K9 inside the TARDIS, the shadow of a boom microphone can be seen on the wall above his head.
 * A number of shots call for the Shadow to lean his head back (when laughing manically or exulting triumphantly). These shots have the unfortunate side-effect of exposing William Squire's real nostrils and making the mask — with its moulded skull-like nose — look blatantly fake.

Continuity

 * When the Doctor calls to K9 to come out of the TARDIS upon arrival on Atrios, he mentions the absence of "water" or "swamps", which kept K9 relegated to the TARDIS on Delta Magna. (TV: The Power of Kroll)
 * The Doctor has been shrunk before. (TV: Planet of Giants, Carnival of Monsters) The dimensional stabiliser of the Doctor's TARDIS was used similarly to shrink before as well. (TV: The Invisible Enemy)
 * In an attempt to evade the Black Guardian the Doctor activated the TARDIS' randomiser and programmed it to travel to approximately 1,000 planets, which took approximately one month. He left K9 aboard the TARDIS while he and Romana took up residence in a London townhouse in the 1920s. (AUDIO: The Auntie Matter)
 * The Fifth Doctor would later encounter Princess Astra on Chaos at the end of recorded time. (AUDIO: The Chaos Pool)
 * The Doctor recalls Troy while miniaturised and hiding in K9, as they head to the hideout of the Shadow. The First Doctor was indeed behind the trick of the Trojan horse in the homonymous war. (TV: The Myth Makers)

On 17 February 1979, as 8.6 million watched Part Five of The Armageddon Factor near its climax…a break in transmission which lasted several minutes. Presumably derived from an off-air video recording, this is a presumably cut-down (1:26) reproduction of it, complete with apologetic continuity announcer and temporary music.
