==Production notes==
This episode was based on [[Paul W. Fairman]]'s "Brothers Beyond the Void", published in the March 1952 issue of ''[[Fantastic Adventures]] '' and also included in [[August Derleth]]'s 1953 anthology collection ''Worlds of Tomorrow''. In this renowned short story, Sam Conrad remains on Earth and it is the lone pilot Marcusson who has the too-close encounter with smaller, more alien Martians. In adapting the tale, Serling made key changes that would deepen the irony and heighten the impact. He installed the apprehensive, defeatist Conrad as the protagonist, easing his fears, only to have them ultimately confirmed; and he presented the Martians as a human-like superior race whose apparent benevolence would make their climactic treachery seem even more shocking, as well as decrease the budget that would have been expended on costumes and makeup.

The [[Martian]] exteriors are taken from the oversize painted background [[diorama]]s seen in the 1956 [[Metro-Goldwyn-Mayer]] film ''[[Forbidden Planet]]''. Additionally, a set of four lights on the wall of the inside of the space ship are reuses of the [[Forbidden Planet|Krell]] power gauges from the same film.  Also, the set for Conrad's home is the ''I Dream of Jeannie'' house.

Marcusson is portrayed by [[Paul Comi]], a frequent guest star in TV shows of the 1960s and 1970s, including ''Star Trek''.  His other ''TZ'' work was in the second season's "[[The Odyssey of Flight 33]]", where he played the co-pilot, and the fourth season's "[[The Parallel (The Twilight Zone)|The Parallel]]".

Actor [[Byron Morrow]] twice appeared as an admiral on ''Star Trek''.  Actor [[Vic Perrin]] was later the "Control Voice" of ''[[The Outer Limits (1963 TV series)|The Outer Limits]]'', and—like Oliver, Morrow and Comi—would also become another veteran of ''Star Trek''.
