Trivia / Star Trek S3 E19 "Requiem for Methuselah"

• Deleted Role: This episode apparently had a scene deleted which contained an appearance by John Buonomo as an orderly.
• Money, Dear Boy / Sci Fi Ghetto: Then-well-known stage actors James Daly and Louise Sorel both thought the series was childish and cartoony and later both admitted the only reason they did the episode was the paycheck.
  Louise Sorel: (about the episode) "They put me in this funny costume – I stood still and they just wrapped fabric around me – and I had an Annette Funicello bouffant and Dusty Springfield eye make-up. James Daly and I thought of ourselves as these two very serious theater actors. He kept looking at me and asking, "Why on Earth are we doing this?" I kept telling him, 'Christmas money.'"
• Prop Recycling: The undercarriage of Flint's robot, M-4, is a reused portion from the upper carriage of Nomad from "The Changeling".
• Referenced by...: The film Ex Machina borrows much from this episode, both sharing the premise of a man attempting to awken a gynoid to full emotional self-awareness and manipulating the hero into assisting them, while having several prior failed gynoid models hidden away.
• What Could Have Been:
  • In one story outline, the 8,000-year-old Flint was also Ludwig van Beethoven. Spock enabled Kirk to forget Rayna by using mental suggestion from a distance, while Kirk was in his cabin and Spock was on the bridge. In the final scene in the episode, Spock causes Kirk to forget but not from a distance, but by touching his head and telling him to forget.
  • In another story draft, Flint also claimed to have been Moses, Jesus and Picasso. NBC vetoed this because they were afraid of offending religious groups and potentially getting sued by Picasso, who was still alive at the time.
