In the episode {Spectre of the Gun}, Kirk, Spock, Scotty and Dr. McCoy are placed in the OK Corral as the Clanton gang, facing off against Wyatt Earp and his brothers. In the 1957 film Gunfight at the O.K. Corral, DeForest KelleyDeForest Kelley played the part of Morgan Earp.
Dr. McCoy's handheld "medical scanners" were actually modified salt and pepper shakers, purchased originally for use in the episode [{The Man Trap}], in which a character was seen using a salt shaker. They were of Scandinavian design, and onscreen were not recognizable as salt shakers; so a few generic salt shakers were borrowed from the studio commissary, and the "futuristic" looking shakers became McCoy's medical instruments.
The 'Star Trek Crews' from all the [Star Trek] series were ranked #2 in [TV Guide]'s list of the "25 Greatest Sci-Fi Legends" ({1 August 2004 issue}).
Gene RoddenberryGene Roddenberry once hypothesized that the Enterprise carried a platoon of Starfleet Marines, but they never appeared onscreen in the original series. The Starfleet Marines would eventually make an appearance, but not until Star Trek V: The Final Frontier and [Star Trek: Deep Space Nine]. The idea was revived with the addition of a group of "space marines" beginning in the [2003-2004] season of Enterprise.
The first interracial kiss on American network television was in the episode {Plato's Stepchildren}, which aired on 22 Nov 1968, when Captain Kirk kissed Lieutenant Uhura. The studio expressed some concern, and it was suggested instead that Spock should kiss Uhura 'to make it less of a problem for the southern [US] audience'. Some stations in the South originally refused to air the episode. Kirk did not kiss Uhura *voluntarily*; they were forced to do it by aliens controlling their bodies. So the first interracial kiss, although between two of the good guys, was the moral equivalent of sexual assault.
Sulu and Uhura didn't have first names in this series. Sulu did get a first name (Hikaru) but not until Star Trek VI: The Undiscovered Country. Fans have tried to give Uhura a first name ("Nyota" or "Penda") but there has never been any official confirmation. Gene RoddenberryGene Roddenberry said Uhura has only the one name, which is Swahili for "freedom". In the eleventh movie in the series, however, the name "Nyota" has been finally entered as her canonical first name.
