The serial received a novelisation written by Terrance Dicks, and several DVD releases. Terror of the Zygons was met with generally positive reviews. The episode's soundtrack, composed by Geoffrey Burgon, was released on 24 January 2000.
Harry is captured by the Zygons, a shapeshifting alien race hiding in their submerged spacecraft. Their leader, Broton, tells Harry that their spaceship had sustained damage and landed on Earth centuries ago to await rescue, but when they discovered that their home planet had been destroyed in a stellar explosion, they decided instead to conquer the Earth and terraform it to suit their physiology. To achieve this goal, they have captured several humans to use as "body prints" to infiltrate key leadership positions, including the influential Duke of Forgill who serves as head of the Scotland Energy Commission. They had also brought an embryonic sea creature called the Skarasen to Earth and augmented it with cyborg technology until it has reached giant proportions. The Zygons are directing it with a signalling device to attack the rigs as part of their larger plan.
Whilst investigating the Skarasen and the Loch Ness Monster, Sarah Jane stumbles upon a secret passageway at the Duke of Forgill's mansion, which leads her to the Zygons' spacecraft. Whilst searching the ship, she locates and frees Harry, who reveals the Zygon stratagem. With their presence discovered, Broton accelerates the Zygons' plan. The Doctor sneaks aboard the ship, frees the remaining humans, and causes the ship to self-destruct, killing the Zygon crew.
Among the rescued humans, the Duke warns that he was scheduled to attend the first international energy conference in London that day, at which several high-level dignitaries will be in attendance. With the conference located in a building near the Thames, the Doctor fears that Broton will lure the Skarasen to attack the conference. Before the Doctor can stop him, Broton activates the signalling device but is killed by the Brigadier; the Doctor recovers the device just as the Skarasen surfaces. The Doctor throws the device into the Thames; the creature eats it and returns to Loch Ness.
The group returns to Scotland to close up the investigation, and the Brigadier reports that the Cabinet will cover up the incident. The Doctor offers them all a return trip back to London via the TARDIS, but the Brigadier and Harry decline.
Terror of the Zygons was commissioned in April 1975 under the working title The Loch, changed later to The Secrets of the Loch.[3] The serial was the first serial that Robert Banks Stewart wrote for the programme. He set the serial in his native country Scotland, and adapted elements of the Loch Ness Monster myth.[4] Stewart subsequently wrote the finale of the season, The Seeds of Doom (1976).[5][6] The serial is set 10 years after its release in 1985.[7]
When Robert Holmes became head writer on the programme he begun to slowly phase out UNIT a process which he intended to complete at the end of season 12, which Terror of the Zygons was the intended finale for, by ending the TARDIS crew's continuous adventures and delivering Harry Sullivan back to Earth.[8][1] However, Stewart could not complete the script in time so the serial was held back and became the first story of season 13, with a reduced order of four episodes instead of the original six.[3][8] When Nicholas Courtney learned of Holmes' plan he suggested that his character should be killed off.[8]
Filming
The episode was directed by Douglas Camfield.[9] Camfield previously directed The Invasion (1967) which introduced UNIT; reportedly Camfield disliked the new costumes used for UNIT and preferred the ones used in The Invasion.[10] Filming had to be rescheduled due to budget cuts. These cuts forced Courtney to exit a theater role.[11] Location filming took place in March 1975.[1] According to Tom Baker, due to rain the filming of the episode was delayed by two days. Baker also stated that due to budgetary constraints, location filming in Scotland was not possible.[12] Instead, location filming for Terror of the Zygons was shot in West Sussex, including at Climping beach, South Ambersham in the South Downs, and at the Hall Aggregates Quarry in Storrington. Studio filming took place the following month.[1]
Terror of the Zygons was released on BBC1 in four weekly parts from 30 August to 20 September 1975. "Part One" was released to an audience of 8.4 million viewers making it the highest viewed episode. It was followed by the lowest viewed, "Part Two", with only 6.1 million. Parts three and four were viewed by 8.2 and 7.2 million viewers respectively. Audience Appreciation Index were taken for the first and third episodes, they scored ratings of 59 and 54. [20]
Critical reception
In The Television Companion (1998), David J. Howe and Stephen James Walker wrote that Terror of the Zygons gave a stereotypical portrayal of the Scottish and showed how much the show had changed since abandoning its regular UNIT premise. They felt that the story gave UNIT its "dignity and believability" and praised the conception of the Zygons, though they noted that the shapeshifting concept was not original. Despite classifying the Skarasen as the "major weakness", they wrote that "the story remains a strong one".[21] In 2010, Mark Braxton of the Radio Times praised the "exquisitely horrible" design of the Zygons and the cliffhanger of the first episode where a Zygon attacks Sarah. He also was positive towards guest actor John Woodnutt and the incidental music, calling the whole production "a class act", aside from the Loch Ness Monster.[1]DVD Talk's John Sinnott gave the story four-and-a-half out of five stars, praising the cast and the design of the Zygons.[22]
Ian Berriman of SFX felt that it was "churlish" to criticise the Loch Ness Monster effect when the story "gets so much right, including first-class direction, pitch-perfect performances and a hauntingly eerie, folky score". He also was positive towards the design of the Zygons and their spaceship, though he found their scheme farfetched.[23] Christopher Bahn, reviewing the story for The A.V. Club, described it as "fun" but noted that it could be formulaic instead of trying to be "ground-breaking"; he criticised the scene in the second episode in which Broton tells Harry everything about the Zygons, which did not leave much surprise for the later episodes. Nevertheless, he praised the cast, the action sequences, and the Zygons, which he described as a "wonderfully surreal triumph of Doctor Who visual design", though otherwise they functioned as a typical monster-of-the-week.[24]
Reviewing the serial in 1999, literary critic John Kenneth Muir acclaimed Terror of the Zygons as "a riveting and horrifying adventure", singling out the fleshy Zygon costumes for particular praise. He drew parallels with a number of historic Doctor Who serials, noting that the Zygon story drew on some familiar Doctor Who ingredients, including alien invasion (The Invasion), "body snatchers" (The Faceless Ones), an oil rig setting (Fury from the Deep), biomechanical technology (The Claws of Axos) and the revelation of an ancient Earth legend to be alien in origin (The Dæmons). However, he was disparaging of the use of a glove puppet to represent the Loch Ness Monster, comparing it to "the Invasion of the Dinosaurs debacle".[25]
A novelisation of this serial, written by Terrance Dicks, was published by Target Books in January 1976 under the title Doctor Who and the Loch Ness Monster.[9]

A new VHS release, also in episodic format, was released in August 1999 in the United Kingdom, and released in 2000 in the United States and Canada.[28]
The serial was released on DVD on 30 September 2013.[29] It features a director's cut version of Part One, with a previously unseen and newly restored 1 min 40-second opening scene featuring the Doctor, Sarah and Harry arriving in the TARDIS, which has materialised invisibly due to a faulty fusion plate. The restored scene was recoloured by Stuart Humphryes.[28] The DVD release also included several promotional items including interviews, advertisements for the serial, and Bakers appearance on Disney Time.[28]
A single-disc version (with no extras) of the DVD formed part of the Fourth Doctor Time Capsule, released on 29 July 2013.[30]
Geoffrey Burgon's music for his Doctor Who serials Terror of the Zygons and The Seeds of Doom were released on CD by BBC Music on 24 January 2000. The CD was sourced from the composer's own copies of the score, recorded at a low speed, resulting in lower fidelity.[31][32]
