WEBVTT 01:00.000 --> 01:15.280 In August 1966, writer Geoffrey Orme submitted a script to the Doctor Who production office 01:15.280 --> 01:22.560 entitled Under the Sea. The story was commissioned, but the production team soon realized that 01:22.560 --> 01:28.960 this ambitious script would be difficult to produce on the standard Doctor Who budget. 01:28.960 --> 01:37.320 Orme's story was dropped in favor of The Imps by Galaxy 4 writer William Eames. Unfortunately, 01:37.320 --> 01:42.920 Eames fell ill and was unable to complete the script. So the production team elected 01:42.920 --> 01:51.200 to reintroduce Orme's story, which was at this point known as The Fish People. The story 01:51.200 --> 01:57.840 underwent a succession of hasty rewrites to reduce the cast numbers and also to introduce 01:57.840 --> 02:04.920 new regular companion Jamie McCrimmon. But the late decision to continue with Orme's 02:04.920 --> 02:10.920 scripts meant that the serial was late going into production. By the time location filming 02:10.920 --> 02:19.320 began in December 1966, the serial had acquired its final title of The Underwater Menace. 02:19.320 --> 02:25.660 Windspit Caverns in Dorset were used for the establishing shots of the volcanic island 02:25.660 --> 02:31.800 and the sequences featuring the series regulars in the first and last episodes. The studio 02:31.800 --> 02:38.480 sequences were filmed in Ealing Television Film Studios, utilizing the facility's water 02:38.480 --> 02:46.340 tank for material involving the fish people, plus the drowning of Professor Zaroff. The 02:46.340 --> 02:52.200 underwater swimming sequences featuring the fish people were achieved by having the artists 02:52.200 --> 02:58.120 playing the creatures suspended by wires. The additional effects of back projection 02:58.120 --> 03:03.640 and slow motion helped to create the illusion of being underwater. 03:03.640 --> 03:08.880 Several of the cast members who featured in The Underwater Menace have notable links with 03:08.880 --> 03:15.920 other Doctor Who stories. King Thousand Atlantis was played by Noel Johnson, who was better 03:15.920 --> 03:23.360 known as the voice of Dick Barton in the famous radio serial Dick Barton's Special Agent. 03:23.360 --> 03:30.720 He would later play Charles Grover, MP, in the John Pertwee story Invasion of the Dinosaurs. 03:30.720 --> 03:36.200 High Priest Lolan, played by Peter Stevens, had appeared in the surreal William Hartner 03:36.200 --> 03:43.840 story The Celestial Toymaker, where he had taken three roles as the knave of Harts, the 03:43.840 --> 03:48.640 kitchen boy and the Billy Bunter type character Cyril. 03:48.640 --> 03:56.240 Scientist Damon, played by Colin Jemans, returned to the world of Doctor Who in 1981 to play 03:56.240 --> 04:01.640 George Tracy in T9 and Company. 04:01.640 --> 04:07.640 Remaining on Earth, the TARDIS leaves the highlands of 18th century Scotland and arrives 04:07.640 --> 04:15.880 on a small volcanic island sometime after 1968. The Doctor and his companions soon find 04:15.880 --> 04:38.160 themselves in the lost city of Atlantis. But is Atlantis really the idyllic city of legend?
