After the international success of Thunderbirds, Gerry and Sylvia Anderson turned their attention to a deadly threat from Mars. Seeking revenge for an attack on their home planet, the Mysterons plot to use their powers to bring Earth to its knees.
Across 32 episodes broadcast during 1967 – 1968, the series is remarkable for moving away from the more caricatured puppets of previous shows – they have more realistic body proportions and the storylines are much more violent and darker in tone. Something reflected in the music which has a more militaristic feel to it although, as always, composer Barry Gray offers up occasional lighter tracks to break up the mood.
The opening narration of each episode sums it up – “The Mysterons: sworn enemies of Earth. Possessing the ability to recreate an exact likeness of an object or person. But first, they must destroy…Leading the fight, one man fate has made indestructible. His name: Captain Scarlet.”
