History Trivia / StarTrekDeepSpaceNine

** Bill Mumy, best known as Lennier in rival show ''[[BabylonFive Babylon 5]]'', or Will Robinson of ''LostInSpace'', appears in "The Siege of AR-558". His one stipulation for crossing over to ''Trek'' was that he '''not''' have to wear any more prosthetics.

** [[BabylonFive General Hague]] as Admiral Leyton in "Homefront" and "Paradise Lost". Pretty ironic, all things considered.

** The writers considered a Kira/Dukat FoeYay scenario (season 4's "Indiscretion", introducing Dukat's half-Bajoran [[MoralityPet love child Ziyal]], is artifact to where things may have headed). Nana Visitor (Kira) [[NoYay flat-out refused to consider the relationship]]. Instead, the storyline was given to Kira's mother Meru as Dukat's "comfort woman" during the occupation in "Wrongs Darker Than Death Or Night."

** While "Trials and Tribble-ations" is regarded as one of the best episodes of the series and a fitting 30th Anniversary for the franchise, there were numerous other ideas which were tossed around. One of which was having the DS9 crew visit the mobster planet from "A Piece of the Action", where they find that the inhabitants have gone on to emulate Starfleet as a commentary on ''Star Trek'' fandom.

* {Homage}: Far Beyond The Stars seems to be a full episode story about ECComics's [[http://asylums.insanejournal.com/scans_daily/54803.html Judgment Day]] which ended the magazine that published it the same time the story is set when the publishers and management disagreed about having the Hero be black.

** Michelle Forbes, playing the part of Ensign Ro, was originally supposed to be DS9's token Bajoran in the cast. Forbes didn't want to commit to a full television series, so the new character of Major Kira was created. (It probably worked out for the best). Ro would end up serving as the station's chief of security in the [[DeepSpaceNineRelaunch relaunch novels]], however.
