John Leeson regularly supplied the voice of K-9 and, occasionally, those of the Daleks and other aliens on the series, as well as its numerous television and audio spin-offs. His role as Dugeen marked his only on-screen appearance in Doctor Who (1963).

John Leeson replaced Martin Jarvis.

The Swampies' make-up s made green using a German product selected by make-up artist Kezia Dewinne for its striking appearance on camera and its resistance to water. Unfortunately, Dewinne had neglected to order the special solvent needed to remove the make-up. As a result, once shooting had wrapped for the day, some of the actors had to be despatched to RAF Bentwaters at Woodbridge to take chemical showers, while the remainder had their skin scoured by hand at the hotel. Despite these efforts, many of the Swampie actors would sport a green tinge for weeks afterward.

Michael Hayes was asked to direct this story.

Philip Madoc replaced Alan Browning.

When script editor Anthony Read asked Robert Holmes to write the story, there were two requirements: that it include the largest monster in series history and that Holmes minimise the humour that many scripts from the era were known for. This second requirement was a request from higher up at the BBC. Early titles for the story were Moon of Death and Horror of the Swamp. Holmes said that he considered the idea of a large monster a mistake given the budgetary constraints at the BBC and named The Power of Kroll as his least favourite Doctor Who story.

Gary Watson was asked to play Ranquin.

Frederick Jaeger and T.P. McKenna were both considered for Ranquin.

Working titles for this story included Moon of Death, The Horror of the Swamp and The Shield of Time.

Fans voted this number 147 in a countdown of the 163 Doctor Who (1963) stories in Outpost Gallifrey's 40th anniversary poll in 2003, making it the least popular installment of the Key to Time season.

Philip Madoc later claimed to regret taking part in this serial because his character was not as interesting as his previous appearance in Doctor Who: The Brain of Morbius: Part One (1976).

This episode was watched by 6.5 million viewers on its original transmission.

The moon is never named on-screen. In his novelisation of the story, Terrance Dicks named the moon Delta III.

According to the liner notes on the DVD, elements of this story were later reused in "The Caves of Androzani". Both stories were written by Robert Holmes.

The story was transmitted over the Christmas and New Year period 1978/1979, leading to higher than normal viewing figures for episode two, transmitted on 30 December.

The Doctor's remark "Will there be strawberry jam for tea?" is a quotation from the short story "The Lumber Room" by Saki.

In A History of the Universe and aHistory, this story is arbitrarily dated to 2878, as Kroll manifests "every couple of centuries" and this is his fourth manifestation, so its been at least eight hundred years since Delta Magna was colonised.

The episodes of this serial are noticeably shorter than average. While it was normal at the time for individual episodes to fluctuate between twenty-three and twenty-five minute, the episodes of this serial clocked in as little as just over twenty-one minutes. The final running time for the whole serial is 90 minutes, as is noted by the DVD of this story.

The BBC's Head of Serials, Graeme MacDonald, was so unimpressed by the set designs in this story that he ordered that designer Don Giles was never to work on the series again.

Michael Sheard was considered to play Dugeen.

This serial was released by the BBC on video cassette in the UK in June 1995.
