First Aired: Feb. 28, 1969 on NBC
Series Main Characters
Mr. Spock: Two hours, fifty nine minutes, to be exact, Captain.
Droxine: Father, are we so sure of our methods that we never question what we do?
Mr. Spock: Your movements awakened me.
Droxine: My apologies. I did not realize they would disturbe you.
Mr. Spock: Only Vulcan ears would find the noise discernable.
Droxine: [with shy, intense interest] It seems that Vulcans are fascinatingly different, in many ways.
Mr. Spock: The same may be said of Stratos inhabitants.
Droxine: Vulcan eyes are very discerning, too.
Droxine: [continuing] I hear that, intellectually, Vulcans are as highly evolved as Stratos city dwellers.
Mr. Spock: [moves to face her] We do... pride ourselves... on our logic.
- Goof (continuity error): In the cave, Kirk strikes the HIgh Advisor with his right hand. It's the same hand which holds his phaser in camera shots before and after the blow, but during the strike the phaser inexplicably disappears.
- Goof (revealing mistake): After Kirk beams down Plasus, the High Advisor of "The Cloud Minders", into the mines and Plasus attacks Kirk, Kirk pushes him back toward the cave wall. When Plasus makes contact with the wall, it stretches inwards to absorb the impact, thus revealing it is made of rubber rather than stone.
- Goof (continuity error): During the shot of Plasus being forcibly beamed directly to Kirk's location in the mines, the bottom of the curtains behind him change position as he transports.
- Goof (audio/visual unsynchronized): At the beginning of "The Cloud Minders", Kirk says, "Who are you? What's the meaning of this attack?" but his lips do not move.
- Major plot points were inspired by Fritz Lang's classic silent film Metropolis.
- David Gerrold conceived the original story on which this episode was based, an outline called "Castle in the Sky". He was deeply disappointed with the final script. His original concept dealt with a three-way conflict between the elite of the planet's sky city and two groups of the cave-dwelling miners - one adhering to the tenets of a pacifist, Martin Luther King-like leader, the other followers of a more militant Malcolm X-like figure. Gerrold's story ended on a deliberately ambiguous note, with the only "triumph" being that Kirk finally managed to establish a dialogue between the groups. Gerrold later characterized the final script - in which the miners' violent actions are blamed entirely on a toxic "zenite" gas in the mines - with the scathing line, "And if we can just get them troglytes to wear gas masks, then they'll be happy little darkies and they'll pick all the cotton we need."
- It has been said that Star Trek was not allowed to show women's navels, but the navels of both women guest stars are visible.
