Terror of the Zygons
Terror of the Zygons is the first serial of the thirteenth season of the British science fiction television series Doctor Who, which was first broadcast in four weekly parts on BBC1 from 30 August to 20 September 1975.In the serial, the alien shapeshifters the Zygons plot to use their cyborg sea monster the Skarasen to take over the Earth, after they discover their home planet was destroyed.The Fourth Doctor, Sarah Jane Smith and Harry Sullivan arrive in Scotland, where Brigadier Lethbridge-Stewart and UNIT are investigating the destruction of oil rigs.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.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.[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.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.[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".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.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).[26] 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.
