The Armageddon Factor (TV story)

The Armageddon Factor was the sixth and final story of Season 16 and concluded the season-long Key to Time story arc. Mary Tamm makes her final appearance as Romana, while her ultimate 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 is traced to the planet Atrios, engaged in a long war with the neighbouring Zeos. The Marshal of Atrios intends a final strike to destroy the Zeons, but the Doctor and Romana discover that Zeos is deserted and the war is being co-ordinated by a computer called Mentalis, built by one of the Doctor's old Time Lord Academy friends, Drax.

The computer is under the control of the Shadow, an agent of the Black Guardian. He and his servants, the Mutes, are inhabiting an unseen third planet positioned between Atrios and Zeos.

The Doctor creates a temporary substitute for the final segment from a substance called chronodyne and uses the Key to place a time loop around the ship from which the Marshal is about to launch his strike against Zeos. It transpires that Atrios's Princess Astra is the real sixth segment. The Shadow converts her into the segment, but the Doctor snatches it and escapes to the TARDIS, where he finally completes the Key.

The White Guardian appears on the scanner screen and congratulates the Doctor. He asks that the Key be given over to him, but the Doctor decides that it is too powerful for any one being to control and orders it to re-disperse.

Enraged, the Guardian reverts to his true colour - Black - and vows that the Doctor shall die for his defiance. In order to shake him off, the Doctor fits a randomiser to the TARDIS's controls. There is now no telling where or when his travels will take him.

Plot
The TARDIS lands on a planet, where the Doctor and Romana conclude their search for the key to time. The Black Guardian poses a threat, but the Doctor foils the Black Guardian's evil schemes. The Princess is the final segment to the key to time.

Story Notes
It was on the set of Doctor Who: The Armageddon Factor that Tom Baker was very angry with some scripts, but Michael Hayes got along with Baker.
 * Originally the sixth segment was to be the Shadow's shadow.
 * Lalla Ward appears as Princess Astra, next season she would play Romana.
 * This story had the working title of; Armageddon.
 * Episode 1 was promoted as the 500th episode of Doctor Who.
 * 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.

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 K-9, "You never f know the answer when it's important!" Producers 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 K-9, who is asked to sing a few bars of "We Wish You a Merry Christmas". The Doctor then asks K-9 what he wants for Christmas; K-9 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 later established in The Happiness Patrol that this is a nickname.
 * The outtake in which Tom Baker barks at K-9 "You never f---ng 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 rumor 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

Discontinuity, Plot Holes, Errors

 * In episode two, after the TARDIS has left, it can be seen behind Romana just after K9 begins blasting a door.
 * In episode three Shapp's gun falls apart when it hits the floor. Why shouldn't it? The same might happen to a porcelain gun of the kind you can find on Earth.
 * In episode four, when K9 exits the transmat, he's got the new left panel he gains in episode five
 * In episode six Astra regains the circlet Merak had used to distract the Mute.
 * Romana forgets that she's already been told (in The Stones of Blood) that it wasn't the President who sent her on the mission.
 * The Doctor says he's never seen K9 spin around before, so he's forgotten about The Pirate Planet. He may have been referring to K-9's behaviour in this particular context, including K-9 unusually imperious dialogue in this scene.
 * In episode six one of the Mutes kicks up a piece of studio carpet.
 * Astra says that she is the sixth princess of the sixth dynasty of the sixth royal house of Atrios. It should be sixth house of the sixth dynasty or it could be a different system to the earth tradition
 * In episode four Merak expounds on how only the Doctor and Romana can get into the TARDIS, despite the fact that he shouldn't even know what it is. His insight continues in episode six, where he talks knowledgeably of the sixth segment, having been told nothing about it. On screen. The scene cuts away during his and Romana's search for the TransMat in episode 3, in which she had plenty of time to explain what they were looking for and why.
 * In episode six Shapp acquires the same ability, somehow understanding the functions of the time loop.
 * Drax repeatedly mispronounces Gallifrey as 'Gallifree'. Perhaps that's how Drax pronouces Gallifrey. Note also that this seems to be Tom Baker's preferred pronunciation: see, for example, The Invasion of Time.
 * Why doesn't the Black Guardian appear to the Doctor in the guise of the White Guardian, instead of arousing suspicion by appearing as the Lord President? He doesn't. He is trying to pass himself off as the white guardian. However, this makes little sense either as he does not remotely resemble the White Guardian the Doctor encountered at the beginning of the season.
 * If the sixth segment returns to its original location and form when the Doctor splits the Key up, does that mean the original segments simply returned to their original locations on Tara, etc.[Its segments probably took different forms.]
 * The Shadow explains that the Atrios-Zeos war was only intended to be a practice run for the universal war the Black Guardian was intending to start once he had control of the Key to Time. Firstly, would a war between two small planets really be a good model for such a vast conflict, and secondly, would a being such as the Black Guardian really require any preparation for causing chaos, given that it is the essence of what he is?

Continuity

 * The Doctor actually has a doctorate.
