Along with 1980’s Captain Scarlet vs. the Mysterons, this film collects episodes of the 1967 series — “Shadow of Fear”, “Lunarville 7”, “Crater 101” and “Dangerous Rendezvous.” It wasn’t well-received by fans of the series and by anyone that hasn’t seen a Supermarionation series — in which Gerry Anderson filmed puppets and made them appear human — it may seem completely deranged.
In 2068, Earth has been at war with the Mysterons, who have a horrific way of dealing with their enemies: they kill them and replace them with clones under their control. Earth’s top military organization Spectrum had an agent named Captain Spectrum who was treated in just such a way, but he was so unstoppable that even his clone broke free from the Mysterons and came back to Earth.
On November 24, 1988, this movie aired as the second episode of Mystery Science Theater 3000 on KTMA. This would be the very first Turkey Day that fans of the show — well, it was only on one UHF channel at the time — would enjoy. The first episode was also shown that day, with Invaders from the Deep, another Gerry Anderson film, was riffed.
You can watch that early episode on YouTube.
