The story was broadcast during the
1972 UK Miner's Strike, which led to many parts of the UK undergoing scheduled power cuts. This may account for the drop in viewers for the last two episodes. According to the DVD notes for
The Peladon Tales, this industrial action partly inspired the sequel
The Monster of Peladon. During production it was noted that Alpha Centauri had a somewhat
phallic appearance. So director Lennie Mayne insisted on the addition of a yellow cape to the costume in an attempt to rectify this. According to the extensive production paperwork published as part of the 2023 re-release of the story as part of
Doctor Who - The Collection Box Set, Hayles' first two commissions were rejected by the production team. The first was titled
The Shape of Terror and did not feature the Ice Warriors. When this was rejected, Hayles was asked to incorporate the Ice Warriors into his next treatment,
Doctor Who and the Brain Dead, which was also rejected. The delays in commissioning the story meant that production of the next adventure,
The Sea Devils was brought forward while Hayles developed the accepted storyline. Working titles for this story included
The Curse and
Curse of the Peladons. The original 625-line master videotapes of the serial were wiped around 1975. In the late 1970s, 525-line
NTSC copies were returned to the BBC from Canada. The tape of Episode Three was in a very poor condition and a salvage transfer to 625-line was made in 1982 for a repeat of the story; the NTSC tape was then reported to be junked. As a result, it was feared that it might not have been possible to make a new
Reverse Standards Conversion (RSC) of the episode. However, the NTSC tape of Episode Three had not been lost but had instead been given to
Ian Levine; Levine then lent the tape to the restoration team. After
heat treatment, the restored NTSC tape was then used to create a new RSC 625-line videotape digital copy. The "Venusian lullaby" sung to Aggedor is to the tune of the
Christmas carol, "
God Rest Ye Merry, Gentlemen".
