Operation -- Annihilate! - S1-E30
Trivia: Don't know if its intentional or not? This is the only episode of Star Trek, (the Original Series) that I know of, where a person makes a sound after being stunned by a phaser. As Kirk and crew stun the group of men with pipes, listen carefully as the last one falls to the ground. He makes a "oh-ah" or groaning sound. After reviewing all the episodes prior and after. This is the only person who makes any kind of noise after being stunned. Maybe it was the parasite infecting his body that allowed him to do this.
Operation -- Annihilate! - S1-E30
Trivia: The dead body of Kirk's brother, Sam, is played by William Shatner.
Trivia: The costume of the Salt Vampire from "The Man Trap" appears in Trelane's castle. It is in an alcove near the front door.
Trivia: William Campbell later appeared as Klingon captain Koloth in "The Trouble With Tribbles."
Trivia: Gene Roddenberry wanted "alien plants" for the planet's surface, but had trouble communicating the idea to the prop department. They sent dozens of lush, green potted specimens, all very terrestrial. A frustrated Roddenberry finally grabbed one potted tree, yanked it out of the soil and stuck it back in upside down with its bare, tangled roots exposed. "There," he grumped. "Now that's an alien plant!"
Trivia: This episode was not broadcast in the United Kingdom for many years due to the BBC deeming its content of the away team being beaten up by children being too scary for its time slot. It was finally shown on the BBC for the first time as part of a complete re-run of the series in the 1990s and nowadays is present in all re-runs of the show.
Shore Leave - S1-E16
Trivia: "Shore Leave" was the first of many Star Trek episodes (and movies) partially shot at Vasquez Rocks, a distinctive California desert rock formation named for a 19th Century bandit who once had a hideout there. Kirk and Finnegan's fistfight and Kirk's encounter with Ruth were both shot at Vasquez. The formation is most prominently featured in "Arena," when Kirk pushes the boulder off its peak onto the Gorn.
Shore Leave - S1-E16
Trivia: William Shatner recalls having a "lame-brained" attack of bravado during "Shore Leave's" filming and insisting that Kirk should wrestle the tiger - without a stunt double. Gene Roddenberry finally convinced him that he was much too valuable to the show to risk his life for a stunt. Thirty years later on a Sci Fi Channel special, Shatner said, "Thank you, Gene, for preventing me from becoming a hair ball!"
Trivia: For her Orion slave girl dance, Susan Oliver was painted green from head to toe. But every time production footage of her came back from the processing lab, no trace of her green make-up job showed on film. After three rounds of Gene Roddenberry ordering the make-up crew to "paint her greener!" it was finally deduced that the lab techs, assuming her color was a lighting error, had been re-tinting her a nice, healthy pink every time.
A Taste of Armageddon - S1-E24
Trivia: The doors and walls of Eminiar 7 are exactly the same as the doors and walls of the Imorg in "Spock's Brain" save for new colors of paint.
What Are Little Girls Made Of? - S1-E8
Trivia: The phaser weapon that Brown, then Andrea, used was from the pilot episode with Captain Pike.
Shore Leave - S1-E16
Trivia: Because Theodore Sturgeon's original script for "Shore Leave" was so complex, many scenes were too expensive to film. Gene Roddenberry had to hastily rewrite many of these minutes before they were shot, resulting in some segments that were ad-libbed because the rewrites hadn't been completed. McCoy's "distracted" scene with Yeoman Barrows is one of these.
The Corbomite Maneuver - S1-E11
Trivia: After Kirk leaves Sickbay, and after McCoy says one of his "What am I...?" questions (i.e., I'm a doctor, not a _______), he says, "If I jumped every time a light flashed around here, I'd end up talking to myself." Later, in Star Trek V, as he's watching Kirk climb the mountain, he says, to himself, "'You'll enjoy Shore Leave. You'll be able to relax'. You call this relaxing? I'm a nervous wreck. If I'm not careful, I'll end up talking to myself."
The Corbomite Maneuver - S1-E11
Trivia: The voice of the Balok puppet in this episode is Ted Cassidy, who played Lurch in "The Addams Family". Cassidy had previously starred as Ruk in the episode "What Are Little Girls Made Of?"
Answer: Kirk was getting his physical and Dr. McCoy probably turned off communications, because if he hadn't, Kirk would have left and headed straight for the bridge, leaving McCoy irritated.
