With a teleplay written by Adrian Spies, the story featured in this episode revolves around an Earth-like planet inhabited by children. If you have not seen the episode, you might be wondering where the adults are in this story.
As the episode unfolds, we learn when children on this planet begin to transition into adults, they contract a fatal illness. Entering puberty somehow causes the disease to manifest in the children, living the planet void of adults.
Without the use of Enterprise computers, Dr. McCoy is somehow able to create a serum to combat the disease which ails the planet’s inhabitants.
Like many “Star Trek” episodes, “Miri” was edited by Fabien D. Tordjmann. Despite being the eighth episode televised, like many other episodes in the series, the placing it had in the broadcast episode sequence does not correspond with how the filming schedule unfolded. “Miri” was filmed twelfth.
Speaking of filming, both “The Andy Griffith Show” and “Star Trek” were produced by Desilu Studios. The situation comedy “The Andy Griffith Show,” created by Sheldon Leonard, Aaron Ruben and Danny Thomas, ran for eight seasons. Since “Miri” was televised during the peak of the situation comedy’s popularity, any Griffith Show fans watching the “Star Trek” episode should have recognised the exterior planetary sets as being the RKO Forty Acres backlot in Culver City which had been acquired by Desilu Studios.
If you look a little closer at the cast lists for the “Star Trek: Deep Space Nine” episodes “Looking for par’Mach in All the Wrong Places” and “Rocks and Shoals,” you should see the name Phil Morris. Morris played the unnamed boy wearing an army helmet in “Miri.”
Further, Morris’ sister Iona was also in “Miri.” While she too played an unnamed character in the 1966 episode, the actress can be seen in the 2001 Allan Kroeker / Roxann Dawson co-directed “Star Trek: Voyager” two-part story “Workforce” playing Umali.
While “Miri” is listed on IMDb as being the eighth episode in the original “Star Trek” series, in respect to this article’s title, “Star Trek: S1.E9. ‘Miri’,” it recognises the existence of the then untelevised Robert Butler directed series pilot “The Cage” as being the series’ first episode.
