* ActingForTwo:
** Kira, Miles & their MirrorUniverse counterparts.
** Bashir gets [[http://www.youtube.com/watch?v=bCmQg6VkQ4A reckd]] by ''Voyager''[='s=] Robert Picardo also (as Dr. Lewis Zimmerman and the Emergency Medical hologram) in "Doctor Bashir, I Presume?". The "archaic" EMH is confronted by the even more presumptuous Holo-Bashir, triggering a four-way catfight between the holograms and their templates.
** While "Nog" was away at Starfleet Academy, Aaron Eisenberg played a Ferengi waiter in "Bar Association".
** Creator/JeffreyCombs, playing clones of the same character, gets to play a good and evil (ie. normal) version of Weyoun arguing over a commink; he also played the Ferengi character Brunt. Combs always wanted to appear as both Weyoun and Brunt in a single scene, but never got the chance. He did, at least, get to play both characters in ''the same episode'', Season Seven's "The Dogs of War".
** "Far Beyond the Stars", "Shadows and Symbols", and (to a lesser extent) "Badda-Bing, Badda-Bang" and "What You Leave Behind" showcased the cast ''sans fards''
*** Combs appears out of makeup twice: once as a corrupt detective in the Bennyverse, and again in "What You Leave Behind" as one of the {{creator cameo}}s in Vic's lounge.
* ActorAllusion:
** Siddig was considered for the lead role because the producers mistakenly took his old age makeup for his real appearance. This is referenced in "Distant Voices" in which Bashir rapidly ages from a silver fox to a doddering geezer.
** O'Brien finds himself 'typecast' as the hitman Falcon in Bashir's spy holoprogram. Whether or not this was intentional, it mirrors Colm Meaney's pre-''Star Trek'' [[TypeCasting typecasting]] as the same ex-IRA bad guy he plays in every film (see ''Film/UnderSiege'').
** In "The Ship", O'Brien waxes poetic about the mountains of Ireland, but another character reminds him Ireland only has hills. Colm Meany starred in the film ''The Englishman who Went Up a Hill (But Came Down a Mountain)'' about a Welsh village that insists its hill is a mountain.
** Creator/JeffreyCombs as Weyoun, who [[Film/ReAnimator had a background in "creative genetics"]]. ("Treachery, Faith, and the Great River")
** A HatePlague causes Garak to go nuts and start killing people in "Empok Nor," much like his serial killer villain in ''Film/DirtyHarry''. Robinson was a little nonplussed about the script, having endured years of people [[IAmNotSpock mistaking him for a total maniac in real life]], but chose to grin and bear it.
** In the episode where [[AndYouWereThere Quark is a writer for a 1950's sci-fi magazine]], there's a note from the editor on his desk [[ItWillNeverCatchOn rejecting the idea of a story about a cheerleader who kills vampires]]. Armin Shimerman was playing Principal Snyder in ''Series/BuffyTheVampireSlayer'' at the time.
** In the pilot, Bashir makes an unwilling Odo put pressure on a victim's bleeding wound, just as Rene Auberjonois's character Father Mulcahy had to do in Film/{{MASH}}.
* ActorSharedBackground:
** Like his character, Andrew Robinson is claustrophobic. He had trouble wearing the prosthetic early on. Garak also spoke of posing as a gardener while conducting surveillance on Romulus. His stint at the Cardassian Embassy coincided with a number of mysterious deaths that year, including a Romulan proconsul who was found poisoned. This is an in-joke by Andrew Robinson, who is passionate about gardening in real life but hasn't murdered anyone. (That we know of.)
** When Kira is complaining about how she feels being pregnant with the O'Brian's baby she says "This is YOUR fault!" to Dr. Bashir. Nana Visitor was [[RealLifeWritesThePlot really pregnant]] with Alexander Siddig's child. Also, in the Bennyverse ("Far Beyond The Stars"), the pulp authors played by Visitor and Siddig are a couple, just like in real life.
** Sisko has an extensive collection of African art (like Avery) which he gradually moves to his new space station digs. In "Past Tense" and "Badda-Bing, Badda-Bang" he's revealed to be something of a Civil Rights historian (again, like Avery), making him a perfect guide into the underbelly of Federation culture. Also, Avery may have been touched by The Prophets in real life... he's [[{{Cloudcuckoolander}} a little off-beat at times.]]
--->'''Creator/WilliamShatner''': Avery Brooks, what a great guy. But he's a little out there. He's doing Jazz things in his head.
* AluminumChristmasTrees: "Far Beyond The Stars" seems to be a full episode about Creator/ECComics's ''[[http://asylums.insanejournal.com/scans_daily/54803.html Judgment Day]]'' (printed around the same time this story is set), which killed the magazine when the publishers and editorial disagreed over having the hero be black. Note also the reference to D.C Fontana, a woman who wrote pseudo-anonymously for The Original Series way back in the sixties.
* AuthorAppeal:
** Ira Steven Behr asked James Darren and Music/IggyPop to play a role because he was a fan of their work. Both ended up getting a LoveItOrHateIt reaction from the fans. Behr is also a movie buff, and nearly all of his scripts include a nod to some distant western or war movie.
** Ron Moore and Ira Behr (the man who gave us [[BLAMEpisode post-op transsexual Quark]] and the Indendant [[FanDisservice nibbling on the Nagus’ withered ear]]) were major drivers behind the Ferengi episodes, which they thought hysterical. These days, even Behr concedes they should have [[http://trekmovie.com/2011/07/06/ira-steven-behr-on-being-trapped-on-star-trek-tng-making-changes-with-ds9/ "admitted defeat"]] and realized they weren't sitcom writers.
--->'''[[http://them0vieblog.com/2015/05/01/star-trek-enterprise-regeneration-review/ Darren Mooney ]]''': Outside of ''Deep Space Nine'', the most enduring impression of the Ferengi was that they had begun their life as “villains that [[HarmlessVillain didn’t quite work]]” and had quickly been transformed into “comic relief that [[TheScrappy didn’t quite work]].”
* BTeamSequel: The first ''Trek'' series to be created without direct input from Creator/GeneRoddenberry, and it shows, especially in the later seasons, which are much DarkerAndEdgier than Roddenberry's optimistic vision of humanity's future.
* TheCastShowOff: Inverted in "Take Me Out To the Holosuite." Max Grodénchik was actually a successful semi-professional baseball player who seriously considered going pro before becoming an actor instead. The reason Rom plays left-handed in that episode despite not being TheSouthpaw in the rest of the show is that Max simply ''couldn't play badly enough'' to convincingly portray the worst player on the team any other way.
* {{Defictionalization}}: Beyond the examples shared with other Trek media, the scifi novel "Far Beyond the Stars" from the episode of the same name was later written and published.
* DirectedByCastMember: Avery Brooks, Rene Auberjonois, Michael Dorn, Alexander Siddig and even guest stars Andrew Robinson and Jonathan Frakes get at least one shot behind the camera. And [=LeVar=] Burton, who appeared in ''[[Series/StarTrekTheNextGeneration The Next Generation]]'', took a spin as well. In fact, Burton was the fifth most prolific director on the series, while Brooks and Auberjonois share sixth place.
* DoingItForTheArt: Frank Langella's uncredited appearance in the first three episodes of Season 2. He didn't want to make it seem like he was appearing on [=DS9=] for money or exposure.
* DuelingShows:
** With ''Series/BabylonFive'' during its '94-'95 run. B5's auteur Creator/JMichaelStraczynski claims that Paramount stole his story treatment, and it got pretty ugly in spots. The two would remain rivals throughout their respective runs, with [=B5=] wrapping up a year earlier in 1998.
** Both had a female commander who began the show as a staid, by the book officer. Over time, Dax and Ivanova became more rough and comedic.
** The dirty-tricks squad Bureau 13 / the dirty-tricks squad Section 31.
** Dukat and [[strike:Lord Refa]] Weyoun concoct a story that Ghemor made a deathbed decision to embrace the Dominion, which is exactly what happened to Emperor Turhan.
** A (barely) oblique reference is made to this on B5. In one episode, a gift shop is set up on the station. One of the characters loudly derides this idea, saying "This isn't some deep-space franchise! This station is ''about'' something!" It should be noted that the writer of this episode, PeterDavid, has written several ''Franchise/StarTrek'' novels. (When he wrote that line into the B5 script, it was with the expectation that JMS and friends would change it, if only to a more subtle jab, before shooting; upon learning that the line was filmed and broadcast verbatim, David remarked to JMS that "...you people are dangerous over there, aren't you?")
** The ''Deep Space Nine'' writers weren't above including their own subtle jabs at B5. One episode featured Bashir having to chaperone a cadre of Ambassadors visiting the station and putting up with all the crap that comes with it. According to JMS, the Writers of [=DS=]9 actually liked [=B5=]. The ''producers'', not so much.
** There are massive parallels between the Sheridan/Shadows and the Sisko/Pa'Wraith arc. [[spoiler:Sisko is marked for death by the Prophets for defying them and takes a high-dive into the Fire Caves, 'killing' him while transferring his essence to a spiritual realm]]: the situation is a mirror of Sheridan's trip to Z'ha'dum and his later vanishing into the Rim.
** [=DS9=] had trouble finding its feet initially, leaning on unresolved arcs from TNG and more or less sticking to its episodic format (not unlike VOY & ENT). As ''Babylon Five'' began to make waves with its much-hyped, five-year war saga, the Dominion War was shortly introduced.
** The intrusion of Section 31 into Federation politics is incredibly similar to B5's [=PsiCorp=].[[note]]The latter was headed by Walter Koenig (Chekov), coincidentally.[[/note]] J.J. Abrams revived Section 31 for the film reboot, making it ''Deep Space Nine''[='s=] longest-lasting influence on ''Trek'' as a whole.
* EnforcedMethodActing: To have an episode where a character questions their entire sense of self is a big ask of any actress, but to claustrophobe Nana Visitor (who was used to a teeny prosthetic on the nose), it was like entering an iron maiden. In "Second Skin", she claws at her Cardassian face as though it is a mask that she wants to rip off – and she actually did, pulling apart her latex and fleeing the set in terror. They somehow managed to get the episode in the can, but it was her hardest episode to film.
* ExecutiveVeto:
** Andrew Robinson explicitly played Garak as bisexual in his first scene with Dr. Bashir. Writer Robert Hewitt-Wolfe corroborated this, adding that Bashir was supposed to be oblivious to his advances. This plot thread was swiftly bundled out of sight by Paramount, though it doesn't ''entirely'' go away (at least as far as Garak's mannerisms go.)
** In "Facets", Sisko [[WillingChanneler willingly allows himself to be possessed by Joran Dax for a short time]]. Avery Brooks was required to do shoot this scene twice. The reason? Brooks' performance was way too scary for a TV-PG show.
** Executive Producer [[http://www.startrek.com/article/rick-berman-looks-back-at-18-years-of-trek-part-2 Rick Berman]] admitted he's unhappy with the direction the series took, but he mostly let Ira Behr do what he wanted, as Rick already had his hands full with VOY and the TNG films. It's reported that Berman reluctantly approved the Dominion war, but only if it lasted for only four or five episodes. The ''[=DS9=]'' writers ignored this mandate and the war stretched out for two years![[note]] [[WebVideo.RedLetterMedia Fuck you, Rick Berman! Yer ruined this, too?! Stop rui-- oh? You didn't ruin this... you were too busy ruining the movies and Voyager... well then... *eats a pizza roll*]][[/note]]
* FakeBrit: Actually averted with Julian Bashir, played by Creator/AlexanderSiddig, an English Arab born in Sudan. This makes one of only three times in the franchise a non-American main cast member was played by an actor of the same nationality (the others being Colm Meaney as Miles O'Brien, and Dominic Keating as Malcolm Reed).
* FakeRussian: Major Kira is reimagined as Colonel Anastasia Komananov ("''[[UsefulNotes/MoscowCentre Gay-Chee-Pee]]''"), in Bashir's totally-not-Franchise/JamesBond holoprogram. Even Creator/NanaVisitor, an American, gleefully admitted that it's a terrible accent. This is commented on by Vic in "His Way". When pressed, he admitted that his sexy Kira duplicate, "Lola Chrystal", is just a modded version of the Colonel Komananov hologram and that it took him forever to get rid of her horrid accent.
* FanNickname:
** Kai Opaka was called "Deep Space Nun" during the first season but was PutOnABus midway through the season.
** Thanks to reviewer WebSite/SFDebris, the practice of calling the ''Defiant'' the ''USS Ben Sisko's Motherfucking Pimp Hand,'' is slowly catching on.
* GermansLoveDavidHasselhoff:
** After taking an extended break to raise her son, Terry Farrell finally started making the rounds at conventions. When she appeared at [=FedCon XIX=] in Bonn, Germany (the largest fan gathering in the world) in 2010, the standing ovation [[https://www.youtube.com/watch?v=PbceUaHkzyM#t=185s lasted for over three minutes.]]
** One noticeable thing about the Ferengi episodes is how beloved they are in the UK and how much Americans seem to loathe them. This may have something to do with [[FawltyTowersPlot British humor.]] As a whole, Europeans react much better to Ferengi episodes than Americans, as the humor, while not necessarily ''bad'', is peculiar and not in the show's usual vein. Only the universally loathed "Profit and Lace" is disliked.
* HilariousInHindsight: Joseph Sisko wanted his son and grandson to come home and take up the restaurant business, and he put them to work in his restaurant whenever they returned home. Cirroq Lofton, who played Jake, got into the restaurant business after ''[=DS9=]'' ended.
* IronyAsSheIsCast:
** Baseball players in "Take Me Out to the Holosuite". Aside from Avery Brooks (Sisko) and Cirroc Lofton (Jake), the actors playing the Ferengi were the best baseball players in the cast. In fact Max Grodenchik (Rom) played college ball. The [[ButtMonkey Ferengi]] being who they are, however, forced them to play left-handed and employ other tricks to look horrible on film.
** Armin Shimerman has been on the board of directors of the Screen Actors Guild and worked against various entertainment corporations to secure actor's rights. Quark is a staunch anti-union and anti-worker's rights Ferengi. Then again, since ''{{VideoGame/Bioshock}}'' came out, he's given interviews stating his appreciation of Creator/AynRand's books, so he may not be so easy to pigeonhole.
* LostInCharacter: A trivia example. Visitor was afraid Kira would rub off her, making her "frightening and aggressive", as it was becoming considerably easier for her to snap at people. She made good efforts to avoid that.
* {{McLeaned}}: Jadzia Dax was killed off after contract re-negotiations with Terry Farrell fell through (the early makeup calls were getting to be too much; several cast members had reached their wit's end by that point). Terry left the show in Season 6 to join the cast of ''{{Series/Becker}}''. She later regretted this decision, calling Jadzia a "superhero."
* TheOtherDarrin:
** Two different people played Quark's mother Ishka, and Tora Ziyal was played by ''three'' different people.
** The actor who plays Alexander is a different one from any of the actors who played him in ''Series/StarTrekTheNextGeneration''. Interestingly, more people are upset about this than either of the above actors, possibly due to his SoapOperaRapidAgingSyndrome.
*** Though apparently Klingons physically mature faster than most races... Alexander would have been about 8 years old when he began military service. Being 1/4 human didn't seem to matter any [[spoiler:considering future Alexander seen on TNG looked fully Klingon regardless of minor human genetics.]]
*** It's mentioned in an episode of ''Voyager'' that in Klingon/human hybrids, Klingon DNA is dominant (hence why Miral Paris, who is only 1/4 Klingon, still has visible ridges on her forehead).
* RealLifeRelative: Kitty Swink, who is Armin Shimerman's wife, played a Bajoran bureaucrat in "Sanctuary" and a Vorta Captain in "Tackling Into the Wind."
* RetroactiveRecognition:
** In "Tribunal", O'Brien faces the worst, most ill-tempered Cardassian judge on the circuit: [[Series/GossipGirl CeCe Rhodes]].
** Two actors from ''Series/BreakingBad'' appear at the beginning and end of the series; Jonathan Banks (''BB'''s Mike Ehrmantraut) appears as an exiled criminal in Season One's "Battle Lines", while Raymond Cruz (Tuco Salamanca) plays a PTSD-suffering soldier in Season Seven's "The Siege of AR-558".
** [[Series/TwentyFour Jack Bauer's wife]], Kira Meru, plays the mother of Kira Nerys in the flashback episode "Wrongs Darker Than Day or Night."
** One of Bashir's savants went on to play Divatox on ''Series/PowerRangersTurbo.''
* RomanceOnTheSet: Alexander Siddig (Bashir) and Nana Visitor (Kira) got together and had a son, with Visitor's pregnancy [[RealLifeWritesThePlot being written into the show]]. They married the next year and divorced in 2001. Which leads to a rather hilarious in-joke in the episode where Kira says "This is all your fault!" to Bashir during an argument, since (in universe) he was the one that did the fetal transplant from Keiko to Kira. Funnier still because [[BizarreAlienBiology Bajoran labor is usually quiet and easy]].
* ScienceMarchesOn:
** Near the end of [=DS=]9, Dr. Bashir asks Odo to donate part of his natural goo to help figure out how to grow new organs. Come the early 21st Century, and humans have nearly perfected the ability to grow organs in a lab - not, admittedly, organs that can change to become the one that is required by an impending surgical procedure (which is what Bashir was aiming for).
** Bashir wanted it to help find a way to grow organs on the battlefield - it's on thing to grow a new organ for a lung transplant when someone has been ill for a couple of months, but it's hard to know how many lungs, hearts, etc to have on standby on a battlefield, nor do you often have the time to grow them as the patient could die before they are fully mature.
* ThrowItIn: A joking reference by Rene to Admiral Ross as "Bill" in the first episode of season 7 was taken literally by the writing staff, resulting in his canonical first name. (As well as confusion for sharp-eyed viewers, as his office nameplate had previously established his first name to be Cliff!)
* TrollingCreator: "The Emperor's New Cloak" sought to combine all three of Trekkies' bête noires: Ferengi, Mirror Universe, and Vic Fontaine. It's thanks to this episode that [[AlternateUniverseReedRichardsIsAwesome Vic Fontaine the Rambo-esque android]] has a ''Memory Alpha'' entry. Because Ira is a crazy person.
* VindicatedByHistory: It goes without saying that [=DS9=] was never in the same league of acclaim as TOS or TNG, and its relative merit ''vis a vis'' Voyager was [[BrokenBase a matter of some debate among Trekkies at the time]]. Nowadays, time has arguably been kinder to [=DS9=] than its sister show, ''Voyager''. Back in '98 and '99, Nana Visitor was giving interviews declaring that one day, fans would come around to liking the show. And voilà: fifteen years later, it's finally caught on thanks to StoryArc structure being more in fashion than episodic television, on-demand streaming making it easier to watch the show in order, and exposure thanks to Moore's later success on ''Series/{{Battlestar Galactica|2003}}''.
-->'''[[https://www.youtube.com/watch?v=z_nenMkNu5o#t=140s Visitor]]:''' I remember sitting with Armin Shimerman on set and going, '[[TheyChangedItNowItSucks They don't really get us]]', and they didn't at the time. But we said, y'know, 10-20 years, they'll get it.
* WagTheDirector:
** If you study ''Deep Space Nine''[='=]s behind-the-scenes' trivia, you realize a good number of the regular and recurring actors became very involved with their character. Especially people like Andrew Robinson and J.G. Hertzler, who each wrote a whole novel about their characters Garak and Martok; or Nana Visitor, who met with the writers whenever she felt a scene was wrong about Kira. Another big name actor, Rene Auberjonois, consulted regularly with the writers (requesting a new uniform for Odo, etc.), though he was a ''little'' more subdued--even if he didn't particularly care for this or that plot development:
--->'''Ira Behr''': Being the pro that he was, he sucked in whatever dismay he was feeling--though I still got some of those vibes. He didn't do a screaming, "I won't do it, I won't play it! No no no!"
** "Rumpelstiltskin" was originally going to be a leprechaun who follows O'Brien around the station like a bad smell. A [[StopBeingStereotypical less-than-amused]] Colm Meany (who had earlier endured an episode full of horrific Irish stereotypes in TNG's "Up the Long Ladder") made the writers change it.
** According to Behr, Armin Shimerman was reluctant to go for broad humor since it went against his deep respect for the Ferengi. (One of Armin's {{old shame}}s is his goofy and [[SpaceJews oddly racist]] turn as Letek in the TNG's "The Last Outpost", which cemented the Ferengi as the laughingstock of the galaxy.) Quark is often the odd man out in {{panto}} storylines such as "Ferengi Love Songs", "Profit and Lace", and "The Emperor's New Cloak". While the other Ferengi (Combs, Shawn, et al.) seem to be getting into the spirit of things, Armin's 'zany' dialog is delivered oddly straight.
** Gul Dukat (Marc Alaimo) was introduced as TheHeavy of [=DS9=]. Very shortly he got sick of playing the baby-eating bad guy and began to play the character as a [[TheCharmer Charmer]]. Problem is, he [[DracoInLeatherPants charmed the audience too.]]
--->"I could have gone one-dimensionally aggressive and mean and ugly with this character if I'd chosen to. I have the feeling that's what they kind of wanted. I thought, 'I've done that a hundred and fifty times already.'"
:::On his approach to playing the role, Ira Behr observed that Marc Alaimo reads every line like he's the hero of every episode he's in. "You listen to Marc talk about Dukat, and it's totally different than I see the character." The writers shrugged and let him carry on believing that, as it added some interesting flavor, but by Season 7 even Alaimo had fallen under Dukat's spell. He decided that Dukat's feelings for Kai Winn were genuine and that he would never strike a monk in a temple. Y'know, this guy who once declared the Bajoran religion a "superstition" and supervised the genocide on Bajor. Slugging a senior citizen over a book rental was beyond the pale for him.
--->'''Behr''': In Marc's mind, I believe he felt his relationship with Winn was legitimate in some way, and that, in some wacky fashion, it was Dukat's bid for legitimacy. I mean Marc was actually ''upset'' when we had him hit Solbor. Until the very end, he wanted Dukat to be the hero of ''Deep Space Nine''.
** Ira Behr and Ron Moore got the itch to pursue a Kira/Dukat FoeYay scenario (season 4's "Indiscretion", introducing Dukat's half-Bajoran love child Ziyal, is a clue to [[WhatCouldHaveBeen where things may have headed]]). Nana Visitor (Kira) [[NoYay flatly refused to do anything of the sort]], pointing out that he was guilty of the brutal occupation and near-genocide of Kira's species. ("If you put a gun to her head, I don't think Kira would ever consider it.") Behr tried his best to jimmy the lock in various ways, such as forming a 'family unit' with Dukat, Kira and Ziyal during the Dominion occupation of Bajor. But in the end, Nana was unmovable. Finally, the storyline was handed off to Kira's mother Meru, who turns out to have been Dukat's "comfort woman" in "Wrongs Darker Than Death Or Night" (co-written by Behr).
** Re: the series finale twist ("What You Leave Behind") of Sisko [[spoiler:dying in the Fire Caves and becoming a Prophet]], Avery Brooks was firm: ''Hell'' no. Given the fact that he was [[UnfortunateImplications an African-American male ditching his wife and newborn child]], Brooks was uneasy about the message they would be sending. The writers suddenly saw his point, and the ending was rewritten to make Sisko's departure more ambiguous.
** Out of all the cast members, Michael Dorn probably had the most pull. After seven years of makeup calls, he wasn't interested in reprising his old role, but the showrunners were so desperate to have Worf cross over that they bent over backwards to make him happy. No longer would Worf be the big guy who got tossed around cargo holds!
** Siddig wasn't too happy about his character being retconned into an Augment. He interpreted it as Behr/Berman et al. attempting to squeeze him into a "Data" role without consulting him, and responded by deliberately reading long equations and statistics in a drowsy, non-eloquent manner. The Augment stuff quickly faded into into the background and became all but irrelevant.
* WhatCouldHaveBeen: Carl Weathers (Apollo Creed from the ''Rocky'' films, Dillon in ''Predator'') was considered for the role of Ben Sisko. Eriq La Salle, Tony Todd and even the voice of Darth Vader himself JamesEarlJones were offered the role of Sisko as well but either declined or were passed over in favor of Avery Brooks.
* WordOfDante: Barry Jenner was mostly winging it while playing the Admiral Ross character. He decided that Ross was a conflicted family man whose son enlisted and died in Starfleet, twisting him into a KnightTemplar who will stop at nothing to preserve the Federation. Internally, at least, he regrets dragging the [=DS9 crew=] (whom he admires) into his machinations.
* WordOfGay: Andrew Robinson has commented in multiple interviews that he considered Garak "omnisexual," and also strongly implied it in the character book he wrote. Robert Hewitt Wolfe has [[http://www.exisle.net/mb/index.php?showtopic=38718&st=160&p=857040&#entry857040 stated]] that he wrote Garak to be attracted to Bashir, but Bashir [[ObliviousToLove never realized this]].
* WordOfGod: Ron Moore stated that although the background check in "Doctor Bashir, I Presume?" ended up marring Bashir's exemplary reputation, this didn't preclude him from being the new template for the Emergency Medical Hologram and -- despite Dr. Zimmerman's complaints -- he did actually end up being selected. Therefore fans assume that either the (unseen) EMH Mark III or Mark IV was based on Bashir.
* WrittenInInfirmity:
** Dax was benched (again) in "Rocks and Shoals" after sustaining injuries from the ship crash. Actually, Terry Farrell was suffering from a skin disorder which made her allergic to sunlight. This made it impossible to shoot scenes in the quarry, so she slept through the episode in a cave.
** Nana/Kira's pregnancy negated any chance of her participating in "Trials and Tribble-ations", so we never get to see her in [[{{Fanservice}} vintage ''Trek'' garb]]. Curses, drat, and blast.
* YouLookFamiliar: Joe Sisko had previously been Admiral Cartwright in the 4th and 6th movies; he's also a case of You ''Sound'' Familiar- Creator/HannaBarbera used him three times as the BigBad in three different series: ''WesternAnimation/GaltarAndTheGoldenLance'' (Tormack), ''WesternAnimation/ThePiratesOfDarkWater'' (Bloth), and ''SwatKats'' (Dark Kat).
