Trivia / Star Trek S2 E22 "By Any Other Name"

• Dolled-Up Installment: The basis of this episode can be found in Gene Roddenberry's first ever produced science fiction script, "The Secret Weapon of 117" for Chevron Hall of Stars in 1956. The episode featured a pair of aliens (the male played by Ricardo Montalbán) who disguise themselves as Humans to study Earth people and get overwhelmed by the sensations and experiences of their new host bodies, and decide to remain Human.
• What Could Have Been: Jermoe Bixby's original script was much darker than the filmed episode. The Kelvans (then called the Dvenyens) executed ten Enterprise crewmembers by opening the shuttlebay doors and letting them get blown out into space. Kirk was put through "hellish torture". Also, crewmembers were chosen to mate with each other (Kirk was paired with Yeoman Leslie Thompson) to eventually breed slaves to the Kelvans. NBC objected against all these, which led producer Gene Coon to order a heavy rewrite on the material. The production staff also deemed the mating aspect too similar to "The Cage".
• You Look Familiar: Hanar is played by Stewart Moss, who appeared as Lieutenant Tormolen in "The Naked Time".
