The Dark Side of the Sun is a television serial written by Michael J. Bird and produced by the BBC in 1983.
The story combines elements of supernatural Gothic romance with the contemporary conspiracy thriller.
There are themes of telepathy and hypnosis, and a secret society, descended from the Knights Templar, holding clandestine meetings on the island.
[3] The historical back-story is linked to the suppression of the Templars, and seems also loosely inspired by the overthrow of Foulques de Villaret, 25th Grand Master of the Knights Hospitaller.
[4] Writing in The Times, critic Dennis Hackett stated he enjoyed the scenery and special effects but was less impressed by the rest.
