List of Doctor Who episodes (1963–1989)

The Enemy of the World is the fourth serial of the fifth season of the British science fiction television series Doctor Who, which originally aired in six weekly parts from 23 December 1967 to 27 January 1968.

The serial is set in Australia and Hungary in 2018. In the serial, the time traveller the Second Doctor (Patrick Troughton) and his travelling companions Jamie McCrimmon (Frazer Hines) and Victoria Waterfield (Deborah Watling) work with the spies Giles Kent (Bill Kerr) and Astrid Ferrier (Mary Peach) to expose the Doctor's Mexican doppelgänger Salamander (Troughton) as having created natural disasters on Earth.

The story is a break from the monsters and "base under siege" of season five, highlighted by a dual role for lead actor Patrick Troughton.

For over forty years, only Episode 3 of The Enemy of the World was known to exist in the BBC's film and TV archives, having been saved from being wiped and junked. However, on 11 October 2013, it was announced by the BBC that the other five episodes had been found and were back in their hands again.[1][2]

The Second Doctor, Jamie and Victoria are enjoying themselves on a beach in Australia in 2018 when the Doctor is subject to an assassination attempt. The boss of the would-be assassins, an agent named Astrid Ferrier, rescues them by helicopter and takes them to her boss Giles Kent. There, the Doctor learns he is a physical double of Salamander, a ruthless megalomaniac who ascended to power by force-growing crops, but is set on increasing his influence. Kent reveals that he had crossed Salamander, who ruined him and removed his various allies. Kent's only remaining ally with any authority is Alexander Denes in Central Europe.

Kent's home is surrounded by troops led by Security Chief Donald Bruce, the Doctor is persuaded to impersonate Salamander to save his companions and to gather more information. The Doctor's impersonation is strong enough to persuade him that he is Salamander — even though the real Salamander is in Central Europe. With Bruce gone, the Doctor's companions agree to infiltrate Salamander's palace in Europe to gather evidence against him. Kent and the Doctor will travel to Salamander's research station in Kanowa to gather intelligence there.

Later, the real Salamander warns that a dormant volcano range in Hungary is about to explode. Denes does not believe this is possible and resists the calls to send pre-emptive relief. Jamie stages an assassination and an impressed Salamander hires him as a guard. On cue, an earthquake begins as the promised volcanic eruption starts. Denes returns to the palace, blaming Salamander for somehow engineering the volcano. Salamander blames the negligent Denes. Denes is arrested.

A suspicious Bruce confronts Jamie about his business in Australia. Jamie refuses to explain. Also suspicious is Benik, Salamander's unpleasant deputy, who has heard from Bruce that Salamander was supposed to be in two places at one time. He visits and intimidates Kent. Meanwhile, Jamie and Victoria use their new roles in the palace to get close to Fariah, Salamander's food taster, hoping to gather information. Fariah reveals she was blackmailed into her role. Jamie causes a diversion to try to facilitate an unsuccessful rescue attempt on Denes by Astrid. Denes is shot dead. Though Astrid escapes, Jamie and Victoria are arrested.

Bruce asks Salamander about his presence in Australia and his relationship with Jamie and Kent. Salamander insists he was not there, and decides to travel to Kanowa immediately to unmask the impostor. Astrid returns to Australia too and contacts the Doctor and Kent. Fariah, having followed Astrid, tells them that Jamie and Victoria are prisoners in the Research Centre. Fariah also hands over the file made by Salamander to blackmail Fedorin— finally convincing the Doctor of Salamander's evil. However, before they can act, the building is raided by Benik and his troops; Fariah is killed and the file is recovered. The others escape.

When he is alone, Salamander dons a radiation suit and enters a secret lift, which transports him to a bunker below the centre. In the bunker are a group of scientists manipulated by Salamander into believing the world above has descended into nuclear war. Salamander is using them to cause small-scale natural disasters under the pretense of stopping the war. One of them, Swann, finds a stray newspaper clipping that contradicts Salamander's claim. Salamander agrees to take Swann to the surface to prove to him the war is real.

Bruce discovers the Doctor and co. at Kent's caravan. Bruce affirms he is not a servant of Salamander, and admits he too is concerned about Salamander's plans. The Doctor and Bruce reach a deal: the Doctor may impersonate Salamander, but if no evidence is found they will all be arrested for conspiracy. Bruce and the Doctor leave, and Kent and Astrid shortly escape.

In the grounds of the research centre, Astrid finds Swann, bleeding after being bludgeoned by Salamander. Before he dies, he tells Astrid about the bunker. Hurrying down there, she learns of Salamander's treachery, and tries to convince the people below.

Bruce and the Doctor have Jamie and Victoria released from the centre, and the Doctor sends them back to the TARDIS. He then goes to the records room, where Kent, believing the Doctor to be Salamander, accidentally reveals that they conspired together to trap the scientists below ground. Astrid arrives, incriminating Kent further as people from the bunker identify him. Kent flees into the cave system beyond the Records Room. There, he encounters the real Salamander, who shoots him in the back. As he falls, Kent sets off a set of explosives that destroy the bunker and damage the research centre.

A shaken and bleeding Salamander takes refuge in the TARDIS, pretending to be the Doctor. The real Doctor arrives, and expresses his intention of turning Salamander to the authorities. Salamander attacks the Doctor, but he fights back with Jamie's help. In a panic, Salamander pulls the dematerialisation switch while the TARDIS doors are still open, and falls out into the time vortex.

This was the last story to be produced under the aegis of Doctor Who creator Sydney Newman, who left his position as Head of Drama at the BBC upon the expiration of his contract at the end of 1967. The four key production roles for this story were all taken by men heavily involved in the development of Doctor Who. Author David Whitaker had been the show's first script editor; Barry Letts, directing the show for the first time, later became the show's producer (for the majority of the Jon Pertwee era), executive producer, and occasional script writer; script editor Peter Bryant became the show's producer from the next story; Innes Lloyd was the show's current producer, but left after this story.[5][6]

Much like the First Doctor serial The Massacre of St Bartholomew's Eve (1966), this serial was influenced by the lead actor's desire to play roles other than the Doctor. Initially, it was planned that Troughton's two characters would meet more than once, but due to the technical complexity, there was eventually only the one confrontation scene, at the story's climax (utilising editing and a split-screen technique). Barry Letts planned six split-screen shots. He called for a matte box to mask half of the camera lens, having read about the technique used for old Hollywood films. The film was rewound after the first take and Troughton was then filmed in his other costume. However, after the first such shot, the camera jammed, and no more split-screen takes were filmed. Later, Letts mentioned this to Derek Martinus, director of the preceding story, who brought Letts up to date with the contemporary technology of filming normally then using an optical printer to combine the material.[5]

Due to British television's shift from 405-line technology to 625-line, in preparation for colour transmissions, going into effect for all BBC shows from 1 January 1968, it was long believed that the switch-over for Doctor Who from 405 lines to 625 came as of Episode 3 of this serial; however, upon the recovery of the other five episodes of the serial, it was discovered that Episodes 1 and 2 were in fact made at 625 lines prior to the official switchover.[7][8] The now-disproved notion of the switch-over occurring at Episode 3 was most likely due to an error in documentation.[9]

Originally, Episode 3 was the only episode of this story to survive in the BBC archives.[10] On 11 October 2013, the BBC announced that the remaining five episodes had been recovered from a television relay station storage room in Nigeria[11] following search efforts by Television International Enterprises Archive and Philip Morris,[12][13] making the serial complete in the BBC television archives for the first time since the mass junkings of Doctor Who episodes between 1972 and 1978. It was subsequently released on iTunes.[1][2] It was the second Season 5 serial to be found in its entirety.

Cast notes

Frazer Hines and Deborah Watling did not appear in episode 4, as they were on holiday.[14] Milton Johns would reappear in the Season 13 serial The Android Invasion and the season 15 serial The Invasion of Time. Colin Douglas would later take a memorable turn as Reuben the lightkeeper (as well as voicing the Rutan scout) in the 15th-season serial Horror of Fang Rock. George Pravda would also reappear in Third Doctor story The Mutants as Jaeger and Fourth Doctor story The Deadly Assassin as Castellan Spandrell.[15]
