Tracks from this episode are used more often than those from any of the other four Gray compositions when scoring subsequent episodes. During the meeting of the two Helenas on Earth, a track of electronic music from UFO (also by Gray) can be heard. Production notes "Another Time, Another Place" was Johnny Byrne's first original script for the series after his original six-week stint on the Space: 1999 production staff was extended to full-time script editor. He started with the concept of the worst thing he could imagine happening to the Alphans: hitting a 'mad cloud or particle storm in space' that causes their bodies to separate into duplicates. With that concept forming the episode's hook, he then had to conceive the next four acts of storyline to reach the conclusion of the Alphans coming face-to-face with themselves. The story would highlight the cyclic nature of human experience—the catastrophic failure of the 20th Century 'techno-man' resulting in a new beginning of the process emerging from the ashes; this idea would be featured in several of Byrne's scripts for the series. The final shooting script contained an unfilmed scene where Koenig, Helena and Carter, making their way to the settlement, encounter the top twenty metres of the Santa Maria satellite tower sticking out of the ashy soil, thus establishing this Earth as their own after the occurrence of some great holocaust. There is also a reference to the Solar System containing eleven planets; this was changed to nine in the revised draft to make the dénouement of their being back in our solar system more obvious to the viewer. The 'This Episode' montage in the episode's opening credits contains an unused effects shot: two glowing geodesic domes sitting on the devastated Earth surface, surrounded by smaller metal pods.
