The first of many The Twilight Zone (1959) episodes (including I Shot an Arrow into the Air (1960), A Hundred Yards Over the Rim (1961) and The Rip Van Winkle Caper (1961)) to be filmed on location in Death Valley. Unprepared for the terrible conditions they would face, the crew suffered extreme dehydration and heat exhaustion and director of photography George T. Clemens even collapsed, falling from a camera crane while filming continued.
This episode takes place from 2046 to 2047.
The vertical panels with a series of holes seen hanging as decoration in Corry's quarters, and flat outside the door, are PSP - Pierced Steel Planking (sometimes called a Marston Mat). This material was developed for World War II to make temporary airfield runways and aircraft stands. The metal planks hook together along the sides, and can be used to provide a hard surface for any number of purposes in isolated areas.
This is the first The Twilight Zone (1959) story pairing Jack Warden with a "human" robot, the second being The Mighty Casey (1960).
