Byron Haskin was known for reusing different items from previous projects for newer efforts (i.e. The Martian War Machines from The War of the Worlds (1953) appearing in Robinson Crusoe on Mars (1964)). For this episode, which also takes place on Mars, he brings back both the Mars Gravity Probe spacesuits, as well as Adam West, for this tale.
The image of the second rocket standing on the surface of Mars next to the wreckage of the M1 is the same matte painting used for a similar scene in It! The Terror from Beyond Space (1958), a sci-fi film which is also about a second, investigatory trip to the red planet.
And - like The Invisible Enemy (1964) - this movie was also filmed by cinematographer Kenneth Peach.
This episode takes place in 2021 and May 2024.
The same prop used for the teleporter in The Mice (1964) and the laser in The Bellero Shield (1964) is seen on the spaceship aimed downward toward the ship's floor.
The makers of this episode were extremely dissatisfied with the results. Haskin said of Adam West: "He was an adequate actor capable of small roles. It was the supporting cast that was poorly chosen."
