History YouLookFamiliar / StarTrek

* W. Morgan Sheppard is a name which may be familiar to you: ''Star Trek'', ''Babylon 5'', and even ''Doctor Who''. He's first seen here in "The Schizoid Man" as Data's 'uncle'. You can also watch him as the Klingon Commandant of Rura Penthe in ''[[Film/StarTrekVITheUndiscoveredCountry Star Trek VI]]'' and the Ahab-like alien Qatai in VOY's "Bliss". Most recently, he was the Vulcan High Council chairman who got told off by Creator/ZacharyQuinto's Spock in ''Film/StarTrek2009''.

* Marc Alaimo appeared as a minor RubberForeheadAlien in Season 1's "[[{{Recap/StarTrekTheNextGenerationS1E6LonelyAmongUs}} Lonely Among Us]]"; Romulan Commander Tebok later that season in "[[{{Recap/StarTrekTheNextGenerationS1E25TheNeutralZone}} The Neutral Zone]]"; a 19th century gambler in Season 5's "[[{{Recap/StarTrekTheNextGenerationS5E26S6E1TimesArrow}} Time's Arrow]]"; and most notably, he played the first-ever Cardassian in ''Star Trek'', Gul Macet in "[[{{Recap/StarTrekTheNextGenerationS4E12TheWounded}} The Wounded]]". Marc Alaimo would become, in ''Deep Space Nine'', Gul Dukat, the main adversary of Captain Sisko.

* Joseph Ruskin has had "only" six roles, but he is the only actor other than Majel Barrett to act with all five casts (appearing with the ''Next Generation'' crew in ''Film/StarTrekInsurrection'').
* John Fleck, instantly recognizable by his smarmy aristocratic elocutions, played both a Cardassian and an alien from the Gamma Quadrant on ''[[Series/StarTrekDeepSpaceNine [=DS9=]]]'', two different Romulans on both [=TNG=] and ''[[Series/StarTrekDeepSpaceNine [=DS9=]]]'', an alien Used Car Salesman on ''[[Series/StarTrekVoyager VOY]]'', and finally semi-BigBad Silik on ENT.

'''Rutherford''': They have, like the same face. They're identical!\\

* Expelled Starfleet cadet Nick Locarno in "[[{{Recap/StarTrekTheNextGenerationS5E19TheFirstDuty}} The First Duty]]" looks exactly like Tom Paris from ''Voyager'', who began the series in prison for having joined the Maquis after earlier having been expelled from Starfleet. The ''Voyager'' creators originally wanted Nicholas Lorcano but when they discovered that the "The First Duty" writer would be entitled to royalties for ''every single Voyager episode'', they gave the character a quick rewrite and ended up with the similar-but-legally-different-enough Tom Paris.

* With the aid of makeup, Creator/JeffreyCombs had recurring roles as Weyoun and Brunt on ''Series/StarTrekDeepSpaceNine'' (once playing both in the same episode although unfortunately the characters didn't share any scenes), Shran on ''[[Series/StarTrekEnterprise Enterprise]]'', and several characters in single episodes of various ''Star Trek''s. Total count (including a cameo in the ''Deep Space Nine'' finale): eight -- one Andorian, one Vorta, two Ferengi, two humans, and two characters of (different) unnamed species.

* Creator/BrockPeters played Joseph Sisko in [=DS9=], and Admiral Cartwright in ''Film/StarTrekIVTheVoyageHome'' and ''Film/StarTrekVITheUndiscoveredCountry''. 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 ''WesternAnimation/SwatKats'' (Dark Kat).

!!Actors who appear in two consecutive ''Star Trek'' series

* Tony Todd who played Worf's brother Kurn in [=TNG=], an elderly Jake Sisko in ''Deep Space Nine'', and the Hirogen Alpha in ''Voyager'''s "Prey".

* Cyia Batten, who played [[TheOtherDarrin the first Tora Ziyal]] (before they decided to go older) and a race car driver in "Drive" (VOY), shakes her money-maker as an Orion slave girl in "Bound".
* Creator/ClintHoward played Balok in the TOS episode "The Corbomite Maneuver" as a child, then as a adult, played Grady in the [=DS9=] episode "Past Tense: Part II" and Muk in the Enterprise episode "Acquisition".

* Mark Lenard had speaking roles as a Romulan in "Balance of Terror", a Vulcan (Spock's father, Sarek), and a Klingon in ''[[Film/StarTrekTheMotionPicture The Motion Picture]]''. Most notably, he was the first Romulan to show his face on-screen, and he was one of the first Klingons with forehead ridges--thus appearing as a member of three of the major galactic powers of the era. [[note]]some sources say he was considered for Lincoln in "The Savage Curtain".[[/note]]

* The penultimate episode of ''Series/StarTrekEnterprise'' featured Creator/PeterWeller as a xenophobic miner who creates a superweapon and is willing to kill anyone (even his own) to achieve his agenda. ''Film/StarTrekIntoDarkness'' features Creator/PeterWeller as a xenophobic Starfleet officer who creates a superweapon and is willing to kill anyone (even his own) to achieve his agenda.

* Creator/MajelBarrett played 'Number One' in the original ''Series/StarTrekTheOriginalSeries'' pilot, Nurse Chapel during the series, and Lwaxana Troi in ''Series/StarTrekTheNextGeneration'', ''plus'' as the voice of various starship computers from ''[[Series/StarTrekTheOriginalSeries The Original Series]]'' up until a posthumous role in Creator/JJAbrams' ''Film/StarTrek2009'' movie. Nobody seems to notice their voices are essentially identical, including Commander Data. Barrett's dual-role as computer voice and Mrs. Troi was referenced tongue-in-cheek in one episode when Mrs. Troi, an apparent technical Luddite, frustratingly accesses the holodeck computer, and [[TalkingToHimself argues with it.]]

* Averted in "[[Recap/StarTrekS1E13TheConscienceOfTheKing The Conscience Of The King]]". Bruce Hyde, who had played Lieutenant Kevin Riley in "[[Recap/StarTrekS1E4TheNakedTime The Naked Time]]" was cast as Lieutenant Robert Daiken, a witness to a massacre. But when producers realized the actor had appeared previously, they decided to rewrite the role as another appearance of Riley.

* In a rare double-YLF, both Merritt Butrick and Judson Scott appeared in ''Film/StarTrekIITheWrathOfKhan'' and the ''Next Generation'' episode "Symbiosis."

* Creator/DavidWarner appeared as Federation ambassador St. John Talbot in ''Film/StarTrekVTheFinalFrontier'', as Klingon Chancellor Gorkon in the very next movie, ''Film/StarTrekVITheUndiscoveredCountry'', and a year later as the Cardassian Gul Madred in ''Series/StarTrekTheNextGeneration'': "Chain of Command".

* William Campbell was best known for playing the Klingon Koloth in both TOS and [=DS9=], but his first ''Trek'' role was that of the god-child Trelane.
