->''"Is there a Tannen in ''every'' century!?"''
-->-- '''[[Franchise/BackToTheFuture Marty McFly]]''', ''WesternAnimation/BackToTheFuture [[AnimatedAdaptation The Animated Series]]''

Family members tend to look like each other. Normally, this follows bloodline -- you tend to look a lot more like your parents than you do your second cousin, for example. Generally, only identical twins can pass for each other, and even then developmental influences can make noticeable differences.

Media, on the other hand, are a little loose with the rules. Especially when it gives the chance to put an actor into a totally new role, or reuse a character design. You see the reuse version in animation from both the East and West because it is pretty easy to just slap a wig on the guy and call him a new person.

While the IdenticalGrandson can marginally argue that it is not unknown for direct descendants to bear uncanny resemblance to a forebear, the idea gets ''very'' shaky for other relations. When a show tries to pass off a male actor in drag as their visiting aunt, or when somehow a character resembles the man who ''adopted'' their great-great-grandfather, it gets flat out weird and hence is usually played up for comedic value. There is a bit of a sub-genre of films that rely on this gag. Eddie Murphy has done a number of them.

See also: ActingForTwo, or YouALLLookFamiliar, which is more of an EnforcedTrope. A subtrope of StrongFamilyResemblance, which concerns the immediate family (usually parent and child).


[[folder:Anime and Manga]]
* In ''Manga/{{Bakuman}}'', Moritaka Mashiro looks very similar to a younger version of his uncle Nobuhiro. However, since the face of his father Masahiro is never revealed, it is possible that the two brothers look very similar to begin with.
* ''Manga/{{Bleach}}'': Ichigo's striking resemblance to Kaien Shiba is noted by Rukia, Ukitake, and Byakuya--who points out that it's ridiculous to get sentimental over because the two are not related. [[spoiler:Byakuya is wrong. Ichigo's father, Isshin ''Shiba'', was Kaien's uncle, so Ichigo and Kaien are first cousins.]]
* In ''Manga/FairyTail'': [[spoiler: Recent chapters reveal that Lucy's distant ancestor, Anna, also looks a lot like Lucy and Lucy's mother, except for a different hairstyle.]]
* In ''Manga/KatekyoHitmanReborn'', there's an example that gets into the flat out weird category (and isn't played for laughs). Xanxus, who [[spoiler: isn't actually supposed to be blood related to the Ninth]] is almost a clone of the Second Vongola Boss. {{Lampshade|Hanging}}d by other characters [[http://www.onemanga.com/Katekyo_Hitman_Reborn/226/08/ here]]. As they say, his temperament, abilities, and even ''looks'' are the same. Makes you wonder [[spoiler: if he really isn't the Ninth's love child]]...
** And then there's Tsuna, who (thankfully) [[UglyGuysHotDaughter doesn't look like his father]], and instead looks exactly like his ancestor, [[{{Bishonen}} Vongola Primo]].
** [[spoiler: Uni]], her mother and her [[IdenticalGrandson grandmother Luce]]. To the point of approaching GenerationXerox.
* ''Manga/DragonBall'': At the end of ''Anime/DragonBallGT'', we see descendants of Bulma, Goku and Vegeta, all of whom look exactly like them.
* All of the Nurse Joys and Officer Jennys are identical to each other in ''Anime/{{Pokemon}}''. The only way you can distinguish them is by the symbol on their hats. The ''Black & White'' series introduced the Don Georges, who are likewise best identified by the trim on their clothes.
* An odd case in ''Anime/DokiDokiPrettyCure''. [[spoiler:The princess Marie-Ange split her heart in two, which became Aguri and Regina, respectively, and her body became Ai-chan who looks like a baby version of her. Aguri and Regina have nearly identical hair, especially when Aguri's bangs are down, just with different hair colors. Regina and Ai-chan have blue eyes like Marie-Angu, but Regina's eyes can turn red and Aguri is the one with red eyes.]]
* In ''Manga/SoulEater'', the resemblance between Asura and Death the Kid is probably down to [[spoiler:them being the 'sons' of [[TrulySingleParent Shinigami]]. While their father doesn't look human, he apparently used the same [[HumanoidAbomination 'human']] [[EeriePaleSkinnedBrunette appearance]] twice over for his two 'fragments'.]]
* Yuki and Yumi from ''LightNovel/MariaSamaGaMiteru'' look like genderswaps of each other. Due to the fact they're the same age fans commonly mistake them for HalfIdenticalTwins but they're not. Yumi and Yuki were only born in the same year.
* ''Manga/OnePiece'':
** Luffy and Ace look remarkably alike and even have the same mannerisms (though Ace is politer) [[spoiler:despite being adoptive brothers. Though it is implied that they are related distantly due to both having the "D" initial in their names]]. Luffy's appearance is also similar to that of his grandfather Garp, who is basically an older, brawny version of Luffy with graying hair and a beard.
** Most male D.s are shown to share quite a few physical characteristics despite not being directly related. The youngest in particular (Luffy, Ace, and [[spoiler:Law]]) have the same unruly dark hair, dark eyes, lean musculature, and are rarely seen without their iconic hats atop their heads.
*** Then there's the eerily similar personality traits that all D.s share, regardless of gender or race (charismatic, destructive, loyal to their beliefs, not afraid of death, disregard for authority, laugh in the face of danger, etc.), that lead many fans to believe that those with the "Will of D." are really all members of a single clan that was scattered centuries ago. The only confirmed clues to their origins so far are that they are [[spoiler:the natural-born enemies of the World Government and that their existence is strongly tied to the Void Century]]. The fact that even those with the D. name themselves haven't the slightest clue of the meaning behind the initial makes the mystery surrounding the "Will of D." even greater.
* Watanuki of ''Manga/XxxHolic'' greatly resembles his distant ancestor [[spoiler:Clow Reed]]. He's the ''only one'' in his family that does.
* ''Webcomic/AxisPowersHetalia'': Spain and Portugal have this, to the point that Seychelles cannot tell them apart when she needs to deliver a message. Though their relationship is ambiguous, they're confirmed to have the same ancestor. Brothers America and Canada are apparently this too, as several times other nations [[MistakenIdentity mistake]] Canada for America (but never the other way around) and take out their grievances with America on him, much to his dismay.

* {{Inverted|Trope}}: Franchise/SpiderMan and his clone Ben Reilly pretended to be cousins with an uncanny resemblance. Peter's wife Mary Jane came up with the explanation for their resemblance, specifically referring to ''The Patty Duke Show''.
* {{ComicBook/Cable}} and his ''ComicBook/AgeOfApocalypse'' counterpart [[ComicBook/XMan Nate Grey]] look different at first glance... but only because of their different ages: teenage Cable is repeatedly shown to look exactly like Nate, SkunkStripe and all, while in a possible future, an older Nate is shown to resemble Cable so much that an elderly Sunfire confused the two. Additionally, when Nate picked up one of Cable's guns, he noted that it felt like it was made for him. This would make more sense if they actually were direct counterparts. However, Cable was the son of Scott Summers and Maddie Pryor, while Nate was the genetically engineered son of Scott Summers and Jean Grey, from whom Maddie was cloned.
* [[http://en.wikipedia.org/wiki/Tweedledum_and_Tweedledee_(comics) Tweedledum and Tweedledee]] of Franchise/{{Batman}} lore are identical cousins.
* ''ComicStrip/ZippyThePinhead'', his wife Zerbina, kids, EvilTwin Lippy, and other members of his extended family are all microcephalics who wear muu-muus.
* There was a Franchise/{{Superman}}-related mini-series in the 90s called ''The Kents'', which examined the lives of the ancestors of the Kent family. One story showed how one of Jonathan Kent's ancestors, Nathaniel Kent, was a pioneer who was largely responsible for turning the state of Kansas into the breadbasket it is today. A fine story, but the artist bizarrely chose to make Nathaniel Kent be a dead ringer for Superman, even though Superman has no blood relation to the Kent family (or any human being) whatsoever. Being, you know, an ''alien'' and all. Partially justified as the frame for this story is Clark reading the Kent family's memoirs, so it could all be in his mind -- and then later stories (mostly involving time travel) established Nathaniel really did look like that. More justifiably, Nathaniel's father Silas looks a lot like Pa Kent with a moustache.
* In the ComicBook/DisneyDucksComicUniverse, most adult members of the Duck and [=McDuck=] families are basically WesternAnimation/{{Donald|Duck}} with accessories (beards, hairdos, [[TertiarySexualCharacteristics bows]] etc.). The same can be observed when you compare Huey, Dewey and Louie with all other Duck and [=McDuck=] kids.
* WesternAnimation/{{Goofy}} has a huge extended family. Just about every single family member, male ''and'' female, looks almost exactly like him, only with one or two minor visual details to set them apart.
* Comicbook/{{Agent 13}}: Sharon Carter, erstwhile girlfriend to Captain America, strongly resembles her aunt (World War II resistance fighter and Cap's wartime girlfriend) Peggy, though the two were originally written as sisters before being retconned into being niece/aunt.
* Comicbook/{{Quicksilver}} and his nephew, [[Comicbook/YoungAvengers Speed]].

[[folder:Fan Fic]]
* ''Webcomic/AxisPowersHetalia'' fanfic ''[[https://www.fanfiction.net/s/12023508/1/Kaitō-Kokoro Kaitō Kokoro]]'': Two of Kiku's and Feliciano's children pretty much inherit their hair colors and hairstyles.
-->"...Sure." The elder sibling took two of them, emerald hues filling with wonder as he took in their sleeping forms. "They're...beautiful." Jade depths turned, glancing upon a boy who had locks styled like the father's, eyes revealing to be the same limpid brown of the mother's as they opened. "So this one's name is Nihon, right?" Those same jade depths switched to the second bundle, the other another boy who had brunet hair like his mother's and the same piercing ebon orbs as his father's. "And this one's name is Ren, right?"
* ''Fanfic/TangledUpInBlues'': Due to a "magical condition", foals in one generation in Taffy's family happen to be identical. It's a humorous justification for the abundance of duplicate background ponies in the original ''WesternAnimation/MyLittlePonyFriendshipIsMagic''. Also used to justify Blues' name (canonically, it's "Noteworthy", according to the toys); Noteworthy is merely somepony who happens to look just like him.
* The ''Disney/{{Frozen}}'' fanfic ''Fanfic/FrozenWight'' has a few instances where Anna, Elsa, and/or Kristoff come across relatives of Oaken's (Oaken being the guy who runs the trading post and sauna where Anna first meets Kristoff in the movie). They look and sound (read, funny Scandinavian accent) exactly like him.
* In another ''Disney/{{Frozen}}'' fic, ''Fanfic/WhatAboutWitchQueen'', Hans closely resembles two of his brothers, albeit in different aspects. Hans and Michael have the same character (EvilPrince, power-hungry, cold, adept at XanatosSpeedChess), while Hans and Ferdinand look absurdly similar, while sharing few if any personality traits.
* One [[https://www.tthfanfic.org/Story-31114-8/CrazyDan+DVRing+it+for+later.htm snippet]] shows that the [[Anime/{{Pokemon}} Joys and Jennys]] are all identical while themselves believing there's only a slight family resemblance because hundreds of years ago, a pair of newly discovered Ditto took the form of a pair of women and slept with one of the scientists researching them. As a result, the women of both lines look identical to most people.
* A crucial plot point in ''Fanfic/PokemonResetBloodlines'' is the appearance of many characters who tend to share the following traits: dark hair, red eyes, [[spoiler: Z-shaped marks on the cheeks like those of Ash]], above-average height and in the girls' case, [[BuxomIsBetter very large breasts.]] [[spoiler: The implication is that all of these were [[ReallyGetsAround fathered by the same man]].]]
* In the ''Series/{{House}}'' fanfic "Incarceration" Wilson's schizophrenic brother Danny (who was never shown in the series) looks exactly like Wilson. Wilson even says people think they're twins.

* One of the greatest and most successful examples of this trope is the black and white comedy film ''Film/KindHeartsAndCoronets''; Alec Guiness plays all 8 members of the D'Ascoyne family. The same film also includes another less dramatic example: Dennis Price, who plays the protagonist, also plays the protagonist's father in a couple of flashbacks.
* The Creator/EddieMurphy remake of ''Film/TheNuttyProfessor,'' where Murphy plays ''every'' member of the title character's family. Though at least in this case he's wearing fat suits to disguise pretty much all his features for the different roles. This aspect of the movie has become the default parody for cheesy comedians who specialise in broad humour. In ''Series/ThirtyRock'', Tracy Jordan is the star of ''The Chunks'', and ''Film/TropicThunder'' features a [[RealTrailerFakeMovie fake trailer]] for ''The Fatties 2'', starring Jack Black's character.
* In the ''Franchise/BackToTheFuture'' trilogy, Creator/MichaelJFox played not only hero Marty [=McFly=], but Marty's two future children (Marty Jr. and Marlene), and his great-great-grandfather Seamus from Ireland. He also posed as Marty's great-grandfather William in a photograph. And Lea Thompson played both his mother Lorraine and his ''paternal'' great-great-grandmother Maggie. The producers have since joked that [=McFly=] men are just genetically predisposed to be attracted to women who look like Lea Thompson. Biff Tannen, his great-grandfather Buford "Mad Dog" Tannen, and grandson from the 2015 part of the second, Griff Tannen, are all played by Creator/ThomasFWilson. This is taken UpToEleven in the animated series, where ''every'' time they visit has an identical ancestor or descendant of Biff, always voiced by Wilson.
* ''Film/StrangeBrew'' briefly does this half-way through the movie. Dave Thomas didn't just play Doug, but his father (with Creator/MelBlanc dubbing over his voice), and Creator/RickMoranis didn't just play Bob, but his ''mother'' (with a woman dubbing over his voice)!
* A variation appears in ''Literature/TheMouseThatRoared''. In the opening sequence, we're introduced to the Grand Duchess, Prime Minister, and Tully Bascombe, all played by Peter Sellers. The narration explains that these disparate residents of the Duchy of Grand Fenwick look like each other because they are all descendants of the country's founder, who was ''literally'' the father of his country (the statue we see of him is clearly a likeness of Sellers).
* In the sex comedy ''Live Nude Shakespeare'', the same actress plays two identical sisters, one a sophisticated socialite, the other a backwoods bumpkin.
* After playing Dante Hicks in ''Film/{{Clerks}}'', Brian O'Halloran also played characters with the surname Hicks in ''Film/{{Mallrats}}'' and ''Film/{{Dogma}}''. It's not explicitly stated that they're related, though, so the ContinuityNod might just be a way to HandWave the uncanny resemblance. WordOfGod says they're cousins.
* In most of Creator/TylerPerry's movies, Perry dresses in drag to play Madea, Madea's brother (not in drag but with a lot of makeup and a wig) and another character (no makeup), who is usually related to Madea.
* In the 1950s ''Film/StTrinians'' movies, Alastair Sim played both the school's headmistress, Miss Fritton, and her disreputable brother. Rupert Everett did the same in the 2007 [[ContinuityReboot reboot]].
* Tia and Tamera Mowry as Sydney Donovan and Sydney's grandmother de-aged to seventeen in the Creator/DisneyChannel movie ''Seventeen Again''.
* Jim Dale as Eli, Wild Billy, AND Jasper Bloodshy in ''Film/HotLeadAndColdFeet''.
* Creator/AdamSandler plays both Jack and his twin sister Jill in ''Film/JackAndJill''.
* In ''Film/AustinPowers'', while they don't look ''too'' similar because of all the makeup, the same actor plays two characters who are revealed as long-lost brothers in the third movie. [[spoiler:It's Mike Myers as Austin and Dr. Evil.]]
* In the movie adaptation of Fred Vargas' novel ''Wash This Blood Clean From My Hands'', both Jean-Baptiste Adamsberg and his younger brother Raphaël are played by Jean-Hugues Anglade, which is especially noticeable in the scenes where they talk together as they have the same voice.[[spoiler: This is perfectly intentional, as Retancourt makes use of the resemblance between the two in order to help Jean-Baptiste escape from the Canadian cops.]]
* In the 1954 UK film ''Film/MadAboutMen'' Creator/GlynisJohns portrays both the free-spirited mermaid (returning from 1948's ''Film/{{Miranda}}'') and stuffy schoolteacher Caroline. The characters shared a great-grandfather.
* In ''Film/CoffeeAndCigarettes'', Cate Blanchett plays herself and her cousin Shelly in a segment called Cousins.
* In the Creator/AbbottAndCostello film ''Little Giants'', Bud Abbott plays the head of a vacuum cleaner company and his much nicer cousin and head of a branch office, who explains the resemblance with a photo of their grandmother (Abbott in drag).
* Plausibility is stretched in ''Film/SmilinThrough'' (1932) in which Norma Shearer plays both Moonyean Clare and her niece Kathleen.
* Played for comedy in ''Film/TheFamilyJewels'' (1965) in which Jerry Lewis plays a total of eight characters, six brothers, one chauffeur, and one faux uncle who is played by Jerry Lewis playing the chauffeur playing a long lost seventh uncle.


* In the fifth book in Creator/LMMontgomery's ''Literature/AnneOfGreenGables'' series, ''Anne's House of Dreams'', a woman who hates her husband is left caring for him for years after he suffers brain damage. [[spoiler:Later he has an operation and recovers his memory--and turns out not to be her husband at all but her husband's cousin. The book explains that the cousins were double cousins, and one set of parents (either their mothers or fathers) were actually identical twins. The cousins looked very much alike, but were easy to tell apart if they were seen together. The wife had never met the cousin, however, and had only heard her husband mention him once. The book also admits that he had changed a lot after his accident and didn't look much like either he or his cousin used to.]]
* In ''Literature/ThePrisonerOfZenda'', one of the kings of {{Ruritania}} has an affair with an English noblewoman, who bears his child. Several generations later, one of that child's descendants bears an uncanny resemblance to the current King of Ruritania, leading to an EmergencyImpersonation. In the 1979 comic film version with Creator/PeterSellers, he plays King Rudolf IV in the opening sequence; once that character dies, he plays both Rudolf V and Syd, the working-class chap who bears the uncanny resemblance. It is implied that Syd was the result of an affair Rudolf IV had.
* In ''The Secret History'', narrator Richard Papen is in love with Camilla, one half of a fraternal pair of twins. She and her twin, Charles, look virtually identical ... and when Richard finds out they're [[BrotherSisterIncest a little too close]], he's titillated by the thought. Eew.
* The post-finale ''Literature/StarTrekDeepSpaceNineRelaunch'' novels reveal that Gul Macet, played by Marc Alaimo in ''Series/StarTrekTheNextGeneration'', is a cousin of Alaimo's ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'' character Gul Dukat. Apparently, the two did ''not'' get along, and another character even speculates that the reason Macet has a beard is that he was trying to lessen the resemblance.
* ''Literature/{{Discworld}}'':
** In ''Discworld/{{Mort}}'', Princess Keli closely resembles her great-great-grandfather, despite being a pampered princess rather than a yurt-dwelling horse barbarian.
** In ''Discworld/TheLastHero'', Paul Kidby's painting of High Priest Hughnon Ridcully is basically Archchancellor Mustrum Ridcully with a better-trimmed beard and a [[NiceHat bishop's hat]]. Possibly justified, as their mannerisms and attitudes are so clearly parallel that there's a good chance they really are identical twins.
* In ''[[Literature/{{Nightside}} Sharper Than A Serpent's Tooth]]'', John Taylor resembles his older male relatives, so much so that [[spoiler: John's late father, resurrected to meet his grown son for the first time, points out John's resemblance to ''his'' father]].
* In ''Literature/TheHoundOfTheBaskervilles'', the late Sir Charles' wayward brother is said to have resembled a family portrait of Lord Hugo, a distant ancestor, to an uncanny degree. [[spoiler:Could be considered a ChekhovsGun, as the brother's secret son is the villain of the story, and both shared Lord Hugo's inclination toward evil.]]
* In the ''Literature/HonorHarrington'' books, Michael Oversteegen greatly resembles his relative, the infamous Baron High Ridge. Oversteegen is, however, otherwise the complete opposite of his relative, being a man of integrity, honor, bravery, and general all-around badassitude who has zero patience for either High Ridge or his various other idiotic relatives who [[{{Nepotism}} somehow wound up in positions of power]] in the High Ridge government.
** Meanwhile, Albrecht Detweiler is stated to bear an uncanny resemblance to all of his sons. Of course, in ''this'' case, the reason is because [[spoiler: they are all his clones. Just as he was a clone of his father.]]
* Emmanuel from ''Literature/{{Malevil}}'' describes his Uncle Samuel, noting that in doing so he also describes himself.
* In the ''Ghosts of Literature/FearStreet'' book ''Horror Hotel Part 1,'' the protagonist discovers that he looks almost identical to a distant relative who's been dead for years. This is bad news, because it turns out that relative was a murderer and his victim's ghost [[PsychicAssistedSuicide is out for revenge]].
* An Uncanny Semi-Family Resemblence: The ancient Greek story ''Aethiopica'', King Hydaspes and Queen Persinna of Ethiopia cast out their infant daughter Chariclea because she is [[ChocolateBaby white]]. After many adventures, it is revealed that she is, in fact, the perfect image of a picture of Andromeda that her mother had looked at while she conceived, and so Chariclea really is their daughter with "maternal impression" explaining her looks.
* In ''Literature/JeevesAndWooster'', Honoria Glossop's cousin Heloise Pringle not only looks exactly like her but has the same exact personality, to the point where Bertie is severely creeped out.
* In Creator/GeneStrattonPorter's ''Literature/{{Freckles}}'', he and his uncle resemble each other strongly.
-->''The likeness settled any doubt. It was Freckles over again, only older and well dressed.''
* In ''Literature/TheWomanInWhite'', Laura and Anne, who resemble each other strongly, [[spoiler:turn out to be half-sisters]].
* In Creator/WenSpencer's ''Literature/{{Tinker}}'', Tinker and Oilcan look more like siblings than cousins.
* In Creator/RuthFrancesLong's ''Literature/TheTreacheryOfBeautifulThings'', Jenny was always described as Tom's miniature, though their jokes about changing places were only jokes. Even after seven years in the LandOfFaerie, Jack can see Tom's resemblance.
* In Creator/ErinMorgenstern's ''Literature/TheNightCircus'', a five-year-old Celia is clearly Hector Bowen's child.
* In ''Literature/HerculePoirot's Christmas'', Simeon Lee's BlackSheep son Harry resembles him to a degree that confuses the family butler when he returns, although his other sons take after their mother (a PosthumousCharacter). [[spoiler: Both of Lee's illegitimate sons also resemble him, throwing the butler into even further confusion and providing Poirot with the vital clue]].

[[folder:Live-Action TV]]
* The Koenig brothers in ''Series/AgentsOfSHIELD'', all of whom are played by Patton Oswalt. A RunningGag is that each brother refers to another as "the shorter one".
* ''Series/AllMyChildren'''s Lily and Ava, identical ''half''-sisters.
* In ''Series/AlloAllo'', Rene is supposed to be shot dead by the Germans but manages to wrangle his way out of it. The explanation? He spends the rest of the series posing as his identical twin brother, also called Rene. Of course half the cast know the truth but they never let slip to the other half.
* In ''Series/AreYouBeingServed'', John Inman, who regularly played Mr. Humphries, also portrayed his mother in a film.
* In ''Series/TheBeverlyHillbillies'', cast regular Max Baer Jr. would occasionally show up as Jethro Bodine's female cousin Jethrine (voiced by Linda Henning). Dietrich Bader did the same as Jethro and Jethrene in the 1993 movie.
* Elizabeth Montgomery as witchy cousins Samantha and Serena on ''Series/{{Bewitched}}''. Jeannie and Sister Jeannie on ''Series/IDreamOfJeannie'' was essentially a straight-up lift.
* ''Series/{{Blackadder}}'': Each of the four series featured a member of the Blackadder family in a different historical era, all played by Creator/RowanAtkinson. Baldrick, Melchett and George were given the same treatment. Specifically, Edmund Blackadder's Scottish cousin [=MacAdder=] appeared in the episode "Duel and Duality".
* In ''Series/BlakesSeven'' Tarrant is revealed to have a brother who looked exactly like him for no apparent reason and [[spoiler: is killed off in the episode he is introduced in without even meeting Tarrant despite having been separated for years]].
* A 1992 ''Series/{{Blossom}}'' episode during which [[ObnoxiousInLaws grandpa Buzz]] tells Blossom how he met her grandmother Ruby in World War II. In the flashback sequence, Mayim Bialik plays Ruby (a member of the Women's Army Corps) while David Lascher (playing Blossom's boyfriend Vinny) doubles as a younger Buzz.
* ''Series/TheBradyBunch'':
** In the episode "Sergeant Emma", Alice goes out of town for a week and has her identical cousin Emma come to fill in for her. Emma is a retired Womens Army Corp sergeant who proceeds to run the Brady household like an Army barracks. HilarityEnsues.
** The episode "You're Never Too Old" has Robert Reed and Florence Henderson as Mike and Carol's respective grandparents.
* The Mayor from ''Series/BuffyTheVampireSlayer'' exploits this trope the same way as Robert Gadling above. Oddly it seems that he's pretty much always been Mayor and no one ever caught on. [[AffablyEvil Well, demon sacrifices aside he IS a really good Mayor]]
* In ''Series/ElChavoDelOcho'' Doña Florinda is exactly like her niece Popis and Chilindrina is exactly like her great-grandmother Doña Nieves, in both cases play by the same actresses.
* Invoked in ''Series/{{Community}}'' episode [[Recap/CommunityS1E18BasicGenealogy Basic Genealogy]]:
-->'''Annie:''' ''[about Abed's female cousin]'' Does she look like you but with a wig and lipstick?\\
'''Abed:''' No, that's Creator/HalleBerry.
* In the ''Series/DadsArmy'' episode "My Brother and I", Captain Mainwaring's degenerate drunken brother Barry, also played by Arthur Lowe, makes an appearance.
* In the ''Series/DiagnosisMurder'' episode "Inheritance of Death", Creator/DickVanDyke played most (if not all) of the elderly members of the Nash family.
* ''Series/ADifferentWorld'': Jasmine Guy playing Whitley Gilbert and Whitley's cousin Lisa.
* In the ''Series/DiffrentStrokes'' sixth season episode "The Van Drummonds", Conrad Bain plays both Mr. Drummond and his female cousin Anna, while Dana Plato plays Drummond's daughter Kimberly and Anna's son Hans.
* When Earl's sister, Pearl, visited on ''Series/{{Dinosaurs}}'', it was played by the same full sized puppet only dressed as a girl. No one really saw the resemblance.
* ''Series/DoctorWho'':
** Creator/FreemaAgyeman had a minor role as Cyber-controlled Torchwood employee Adeola Oshodi in [[Recap/DoctorWhoS28E12ArmyOfGhosts "Army of Ghosts"]]. When she was subsequently cast as the Doctor's new companion Martha Jones, a line of dialogue in her [[Recap/DoctorWhoS29E1SmithAndJones first episode]] referenced her cousin Adeola.
** Also done with Eve Myles, who first appeared in an [[Recap/DoctorWhoS27E3TheUnquietDead episode]] centered around Charles Dickens. Myles was later cast as Gwen Cooper in the spin-off ''Series/{{Torchwood}}''. When the members of Torchwood 3 appeared on ''Doctor Who'', it's explained that the earlier character is a distant relative of Gwen's, further influenced by some TimeyWimeyBall effect that makes them identical.
* Ricky Gervais and Stephen Merchant comment upon this trope in behind-the-scenes material for ''{{Series/Extras}}'', musing on introducing a sister for Gervais' character in the show's sitcom-within-the-sitcom -- played by Gervais, with the only difference being an alternate pair of glasses. Indeed, the sister appeared in this manner in the ''Extras Christmas Special''.
* Larry "Grand-Ma-Ma" Johnson, in commercials and in ''Series/FamilyMatters''. Also in ''Family Matters'', Jaleel White playing Steve Urkel, and his cousin Myrtle.
* In ''Series/{{Friends}}'', all of Joey's 7 sisters, while not played by the same actor, had almost identical appearance, hair style (dark and voluminous) and even similar names. This is a plot point in the "The One Where Chandler Can't Remember Which Sister", when Chandler makes out with one sister and can't figure out which one.
** Separately on ''Friends'', Lisa Kudrow played Phoebe Buffay and her sister Ursula, but it's justified as the two are supposed to be identical twins.
* In the early '90s, ''Series/GeneralHospital'' brought back fan favorite Anthony Geary, not as his iconic character Luke Spencer -- who he refused to play if he were not accompanied by the equally legendary Laura -- but as Luke's lookalike distant cousin Bill.
* One episode of ''Series/TheGoldenGirls'' had Creator/BeaArthur play her character Dorothy's grandmother in a flashback.
* ''Series/GoodLuckCharlie'': A video of Bob from his high school basketball days shows that he looked ''exactly'' like his son P.J. does today, only with [[EightiesHair longer hair]].
* ''Series/GameOfThrones'':
** Lord Rickard's facial structure is almost a dead ringer for Ned's somber look in his later years (as portrayed by Creator/SeanBean), and his hair is tied up in the same way as Jon Snow's in Season 6. It does tie a lot into how Jon looks more legitimately a Stark despite not being Ned's direct descendant.
** Tommen grew up to look identical to his first cousin once removed (on both sides, of course) Martyn Lannister in the next season as Chapman had played the small role of Martyn in Season 3 before taking over the role. But given how much incest is in their family, can anyone blame them?
* Thrice on ''Series/HannahMontana''. Music/MileyCyrus plays [[TheDanza Miley Stewart]] and her visiting cousin Luann Stewart. At the same time, Billy Ray Cyrus plays both girls' fathers, Robbie Ray and Bobby Ray. In another episode, Moises Arias plays both Rico and Rico's rival Australian cousin, Angus.
* On ''Series/{{Haven}}'', Audrey looks eerily like her mom, Lucy, who was in the town in the 80s. Given recent revelations, there may be a reason for that. [[spoiler:Audrey ''is '' Lucy. She is apparently immortal and has amnesia.]]
* Played straight on ''Series/HerculesTheLegendaryJourneys'', where Iolaus had a look-alike cousin in two episodes. Inverted, however, with Kevin Todd Smith playing both Iphicles and Ares. Both are half-brothers to Hercules, but they aren't related to each other.
** Jodie Rimmer played Lilith on ''Series/YoungHercules'' and daughter Seska on ''Hercules''. {{Lampshade|Hanging}}d by Seska referring to her mother as a "wild one" back in the day.
* Ali Larter on ''Series/{{Heroes}}'' played Nikki Sanders, a hero with super strength and multiple personalities. After [[spoiler: Nikki was killed in season two]], Larter went on to play [[spoiler: Tracy Strauss, who had the ability to freeze objects and who was apparently Nikki's twin sister. There was supposedly a third "twin", Barbara, but she has not been seen and it is unsure whether she has powers.]]
* On ''Series/KyleXY'', Kyle is identical to his father Adam and Jessi is identical to her mother Sara, and well-cast adult actors were given to justify this. Both characters could have ''easily'' been clones, given the circumstances of their gestations, but each was later given the other biological parent.
* ''Series/MacGyver1985'': Jack Dalton and his father, Jack Sr., in "Ma Dalton".
* In ''Series/TheManFromUNCLE'' first season episode "The Bow-Wow Affair", series regular Leo G. Carroll played both his regular role as U.N.C.L.E. chief Alexander Waverly, and a one-time role as Waverly's cousin, Quentin Lester Baldwin.
* ''Series/MarriedWithChildren'':
** Marcy D'Arcy's cousin, Mandy. This is lampshaded by Bud and Peggy, who start discussing this trope:
--->'''Bud:''' Identical cousins. There's no such thing.\\
'''Peggy:''' Well, sure there is! [[Series/{{Bewitched}} Samantha and Serena]]; [[Series/ThePattyDukeShow Patty and Cathy...]]
** Ed O'Neill also played Al Bundy's father in a couple of dream sequences.
* Martin Lawrence in ''Series/{{Martin}}'' playing his mother. And although not related, Martin looked a lot like his neighbor Shenaenae, Gina's brat neighbor Roscoe, Gina's coworker Bob from Accounting, Otis, Dragonfly Jones, Jerome, and Elroy.
* On ''Series/{{MASH}}'', Gary Burghoff once played Radar's mother in a home movie.
* The season 9 episode ''Dead Letters'' of ''Series/MidsomerMurders'' features two actors returning from the pilot, playing relatives of their original characters (who had been murdered in the pilot). That someone looks much like their sister might not be so strange, but someone looking very much like their cousin (including ''hairstyle and clothing sense'') despite never having met their relative does help to explain why Barnaby is confused by their appearance.
* In the finale of ''Series/MightyMed'', [[spoiler:this is revealed to be why Hapax the Elder looks exactly like Alan, as Hapax is Alan's paternal grandfather]].
* In ''Series/{{North and South|US}}'', Madeline's mother was her identical double. The resemblance was so great that a man who had only seen Madeline's photograph recognized her as being the daughter of a woman whose painting was hanging in a whore house he had visited some years before. The difference is that the woman in the painting is considerably darker, and Madeline (Lesley-Anne Down) was blackmailed by the man because he knew she was a closet African American.
* ''Series/ThePattyDukeShow'': Patty Duke has an identical cousin.
** Somewhat justified since Kathy and Patty Lane's fathers (played by William Schallert) were identical twin brothers.
** Frequently spoofed. ''Series/FullHouse'' occasionally subverted this by having one of the Olsen twins play Michelle and the other play a cousin from Greece.
** Similarly, during the mid-1980s, ''Series/KidsIncorporated'' had Renee Sands play her [[TheDanza character of the same name]] as well as British cousin Samantha on a couple of episodes.
* In ''Series/ThePersuaders'' episode "A Death in the Family", Roger Moore plays three members of his usual character's family, including a woman. This is lampshaded at the end when Danny Wilde's aunt arrives, played by... his co-star Tony Curtis.
* In ''Series/QuantumLeap'', Scott Bakula plays his character's own father (albeit in makeup) in the episode ''The Leap Home''.
** In the pilot episode, another actor played his father at a younger age, while a different young actor played Sam, with Scott Bakula's voice dubbed in whenever he spoke.
** Bakula also played his father in one scene in the episode "Promised Land" when Sam Leaped into someone else in his hometown.
* The short-lived 1960s sitcom ''Series/TheSecondHundredYears'' featured Monte Markham as both modern day urbanite and his crotchety old grandfather, an Alaskan gold miner who had been trapped in the ice for 67 years, and recently thawed.
* Newman of ''Series/{{Seinfeld}}'' in "The Bottle Deposit", while figuring out how to transport bottles and cans to Michigan, considers a photo of his mother, which is actually Wayne Knight in a wig. In another episode, Frank Costanza finds a photo of someone who looks exactly like him and figures it must be his cousin Carlo. He flies to Italy to meet him, only to find out his name is Guiseppi. Guiseppi/Carlo is played by Jerry Stiller, and rather poorly done by Seinfeld standards.
* ''Series/StarTrekTheNextGeneration'':
** Brent Spiner plays Data, Lore, B4, ''and'' Dr. Soong. Justified in that the first three are androids whose faces were formed from moulds of the face of their creator, Soong. Spiner came back on ''Enterprise'' and played, yes, Dr. Soong's grandfather.
** Picard's nephew is identical to him as a child, obviously because they're both played by the same actor. This gets funnier when Picard says that his nephew looks exactly like his brother as a child, which would seem to indicate that Jean-Luc and Robert were identical non-twin brothers. A more cynical viewer might start wondering just how close Jean-Luc and his sister-in-law were around the crucial time.
* In ''Series/StarTrekTheOriginalSeries'' William Shatner played Kirk's brother George Samuel Kirk in one episode. The only distinction between both characters was that George had a mustache.
* ''Series/TheSteveHarveyShow'': Cedric the Entertainer plays Coach Cedric Robinson and Grandma Pudding.
* In a few live-action segments of ''Series/TheSuperMarioBrosSuperShow'', Mario and Luigi were visited by many relatives who all looked like them (for example, their mother was obviously Mario's actor in drag).
* ''Series/TeenWolf'''s Kira shares a very strong resemblance to her mother as a young woman, to the extent where her mother in a flashback episode is played by the same actress as Kira.
* In one episode of ''Series/ThatsSoRaven'', Creator/RavenSymone played about 3 or 4 roles (including her uncle, her grandma, and her baby cousin).
* The villain in "Reign of Terror", an episode of ''Series/TheTimeTunnel'' set in UsefulNotes/TheFrenchRevolution, is played by Whit Bissel, a series regular as General Kirk, the military head of the Time Tunnel project. Kirk is confused as his family is from Scotland, but eventually discovers there was a previously unknown French branch.
* In ''Series/TwinPeaks'' Laura Palmer and her dark-haired cousin Madeline (a nod to ''Vertigo'') are both played by Sheryl Lee.
* In the ''Series/WonderWoman'' TV series (1975), the first season takes place in 1942, where Wonder Woman attaches herself to love interest Steve Trevor, played by Lyle Wagner. In Season Two, the show is retooled to take place in modern times. Lyle Wagner plays Steve Trevor again, but this is supposed to be the original Steve Trevor's son.
* Everyone in Paul Pfeiffer's family on ''Series/TheWonderYears'' has black hair and glasses, in a rare example of this being done with different actors. It's kind of like Milhouse's family on ''WesternAnimation/TheSimpsons''; Milhouse is also based on Paul in appearance and as the protagonist's best friend.

[[folder:Newspaper Comics]]
* In ''ComicStrip/{{Peanuts}}'' Linus and his little brother Rerun look almost exactly the same. The only way they can be told apart is height, hair (Rerun's is a bit flatter) or outfit (Linus wears red and black stripes while Rerun wears overalls).

[[folder:Puppet Shows]]
* ''Series/SesameStreet''
** Elmo has various cousins who've appeared on occasion, who are all based on the Elmo puppet with different accessories.
** Oscar the Grouch and Cookie Monster also have some identical relatives. Though in this case, it may have to do more with their species rather than bloodline.
** [[http://muppet.wikia.com/wiki/Da_Niao Da Niao]] on ''Zhima Jie'' (Chinese version) is Big Bird's identical cousin. Other characters in international productions have been identical to American characters or said to be their relatives, but not both at the same time.
* Similarly Emily "Ma" Bear in ''Series/TheMuppetShow'', ''Film/AMuppetFamilyChristmas'' and (as Mrs Fozziewig) ''Film/TheMuppetChristmasCarol'' is identical to her son Fozzie except for [[TertiarySexualCharacteristics a dress]], [[FurryFemaleMane grey hair]] and glasses.
** In an early episode, an unnamed cousin of Fozzie's was in the theater audience. He was virtually identical except he wore a bowler.
** In the ''Franchise/StarWars'' episode of the show, Creator/MarkHamill appears as both Luke Skywalker and himself; it's stated they are cousins.

* OlderThanSteam: Viola passing for her [[HalfIdenticalTwins twin ''brother'' Sebastian]] in Creator/WilliamShakespeare's ''Theatre/TwelfthNight''.
* There have been productions of ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'' in which the same person who plays Johanna also plays her mother Lucy in the flashbacks.
* In ''The Rocky Horror Show'', which inspired ''Film/TheRockyHorrorPictureShow'', Eddie and Dr. Scott are (traditionally) played by the same actor.
* In Book-It Repertory Theatre's play of ''Literature/SenseAndSensibility'', (non-twin) brothers Edward and Robert Ferrars were played by the same actor.
* In the play ''I Hate Creator/WilliamShakespeare!'', the skit based on ''Theatre/{{Hamlet}}'' contains these lines (along with a suggestion that the characters in question be played by the same actor):
--> '''Hamlet:''' Ophelia! You're not dead!
--> '''Laertes:''' It is I, Laertes, son of Polonius and brother of Ophelia, so I can see where you would make that mistake.
* The ''Theatre/MrsHawking'' play series: Nathaniel to his uncle the Colonel. They are supposed to look very strongly alike, and in part IV: ''[[http://www.mrshawking.com/sample-page/scripts/gilded-cages-stage-play/ Gilded Cages]]'', when both characters appear at roughly the same age at two different points in the timeline, they are designed to be played by the same actor.

[[folder:Video Games]]
* In what is part this trope and part Strong Family Resemblance, in ''[[VideoGame/BackToTheFuture Back to the Future: The Video Game]]'', Marty runs into his grandfather, Artie [=McFly=], who looks and sounds just like George [=McFly=] (both being based on Creator/CrispinGlover's performance in the film). Artie's father, William, is once again played by Creator/MichaelJFox, who had previously portrayed him in a photo shown in the third film (even though Marty himself is actually voiced by AJ [=LoCascio=]). This leads one to believe that if the pattern continues, since Marty's son will end up looking like Michael J. Fox, his grandson and great-grandson will look like Crispin Glover, and so on. Also, Kid Tannen is basically just Biff with a moustache and zoot suit.
* In ''VideoGame/KnightsOfTheOldRepublicII'', textual implications suggest Echani genetic variation in terms of appearance is very small, with siblings all looking like identical twins and almost identical to their same-sex parent. It was all a cheap way of explaining why they used [[OnlySixFaces the same model]] for all of Atris' Handmaidens while still having them be siblings, despite having an explicit note the one that joins you looks different due to being their half-sibling and yet still looks the same. When the Exile inquires about this the Handmaiden is genuinely surprised that you've noticed, since outsiders typically don't. To Echani on the other hand, her illegitimacy is ''[[ChocolateBaby obvious]]''.
* In ''VideoGame/{{Paranoiac}}'', it's mentioned that Miki not only looks incredibly like her dead ''aunt'', Saeki, but their personalities are just as similar. [[spoiler:Both are described to be [[NiceGirl nice girls]], but mental illness runs in the family and both began to suffer from depression. Saeki's depression got worse, to the point of paranoia and eventually committing suicide, with Miki potentially going the same path, as shown in the Bad Ending.]]
* In ''VideoGame/SuikodenV'', Dragon Cavalry commander Rahal and his CloudCuckoolander sister Rania look virtually identical, to the point that they'd fall under HalfIdenticalTwins if not for Rania being a year older. Not immediately obvious for most of the game, due to Rahal wearing battle armor and Rania being in civilian dress, but when the plot calls for Rahal to [[WholesomeCrossdresser dress as a woman]] the ''only'' visible difference from his sister is that she wears glasses and he doesn't. Apparently they have a history of exploiting this for pranks.
* In an example that would make Nurse Joy proud, recurring ''Franchise/FireEmblem'' series character [[PluckyGirl Anna]] is finally [[AscendedExtra promoted to a playable character]] in ''VideoGame/FireEmblemAwakening''... but she also runs the [[DownloadableContent Outrealm Gate]] and appears as a traveling merchant in the same game. As it turns out, there are more than half a dozen "Annas", and they're all sisters. Since the Outrealm Gate is described as a portal to other worlds, this could also explain how she manages to show up in so many otherwise separate worlds across the series...

[[folder:Visual Novels]]
* In ''Franchise/AceAttorney'', brothers Kristoph and Klavier Gavin look almost exactly the same, down to the hairstyle. Their resemblance makes the first encounter between Apollo (who used to be mentored by Kristoph) and Klavier a bit awkward: Apollo couldn't help but stare, and Klavier... [[MistakenForGay got the wrong idea.]]
--> '''Klavier''': I must say I'm used to being inspected by the ladies... But this is the first time I've felt this way with a man.

* Claire and Clinton in ''Webcomic/QuestionableContent'' look so similar that they were initially mistaken for HalfIdenticalTwins, although Claire is actually several years older. They have the same face, freckles, hair and eye colour, and even similar glasses.
* Daisy and her aunt, Blue in ''Webcomic/NicoleAndDerek'': With her hair dyed blue, Daisy is a dead ringer for Blue, as she appeared in the previous comic, ''Webcomic/NamirDeiter''. So much so that patrons of the bar (Blue owns, Daisy works there) think she's Blue. One character assumed they were mother and daughter.
* Used as a plot point in ''Webcomic/ElGoonishShive'' - the reason Diane and Susan look so similar to each other is [[spoiler: that they're ''both'' descendants of Adrian Raven, a half-immortal. Susan is a descendant from a woman he'd been with in his ''[[Really700YearsOld actual]]'' [[Really700YearsOld Twenties]], while Diane is his direct daughter]].

[[folder:Web Original]]
* Every single foreign character in ''WebAnimation/TheFrolloShow''. Whether they be Arabic, German, Russian, Mexican, or any other nationality, the only thing that distinguishes a foreign character from their main character cousin is the hat they wear.
* [[http://akaichounokoe.deviantart.com/art/Punk-Brownie-461301053 Brownie]] looks an awful lot like her toddler cousin [[http://akaichounokoe.deviantart.com/art/Angelica-380145801?q=sort%3Atime%20((angelica)%20AND%20(by%3AAkaiChounokoe))&qo=1 Angelica]].

[[folder:Western Animation]]
* PlayedForDrama with [[GenkiGirl Ty Lee]] from ''WesternAnimation/AvatarTheLastAirbender.'' She was [[MassiveNumberedSiblings one of septuplets]], and she ran away from home [[IJustWantToBeSpecial to avoid becoming part of a "matching set"]].
* In SequelSeries ''WesternAnimation/TheLegendOfKorra'', Mako and Bolin meet their late father's relatives in Ba Sing Se. It'd be easier to count the cousins who ''don't'' have the same snub nose and [[BigOlEyebrows heavy eyebrows]] that Bolin has.
* ''WesternAnimation/BackToTheFuture: The Animated Series'' took this to ridiculous levels by having a Tannen in every timeline they go to, no matter what country. Taken UpToEleven when they even encounter a T-rex Tannen in a timeline where the dinosaurs weren't wiped out.
* In ''WesternAnimation/SouthPark'', pretty much everyone in the extended Cartman family is overweight and has his same annoying tendencies (whining, eating too much, etc.) The only exceptions seem to be Cartman's mother and [[http://southpark.wikia.com/wiki/Alexandra_Cartman a young girl who resembles her]].
* Chum Chum's cousin [[SdrawkcabName Muhc Muhc]] in ''WesternAnimation/FanboyAndChumChum''.
* In ''WesternAnimation/ScoobyDooAndTheLochNessMonster'', Daphne's Scottish cousin Shannon looks just like her, only with short hair and a tartan skirt, and is voiced by the same actress doing a Scottish accent. Daphne is also identical to her 4 sisters ([[AlliterativeFamily Daisy, Dawn, Dorothy, and Delilah]]) in ''WesternAnimation/ScoobyDooMysteryIncorporated''. The only things that physically differentiate them are their hairstyles and clothes.
* In an episode of ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'', the Neutrons have a family reunion where everyone looks like Hugh (except for one who's a caricature of creator John A. Davis).
* Both WesternAnimation/TomAndJerry have identical cousins; Jerry has the super-strong Muscles ("Jerry's Cousin"), while Tom has his cowardly (and mouse-phobic) cousin George ("Timid Tabby"). Naturally, mistaken identity gags abound in both cartoons.
* The Flim Flam brothers from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' look almost completely identical, but they can be distinguished by their cutie marks and by the moustache on one of them.
* ''WesternAnimation/TheLoudHouse:'' You can clearly see that the Loud kids are all siblings but Lincoln and Lucy take it to an extreme. Lincoln strongly resembles his grandfather down to the white hair, while Lucy looks like an exact copy of her great grandmother.
* In ''WesternAnimation/Ben10UltimateAlien'', Gwen has an identical cousin, Sunny, though her true form is her Anodite form.
* In one episode of ''WesternAnimation/TheNewScoobyDooMovies'', Shaggy is showing Scooby pictures of his relatives, and they all look exactly like Shaggy, right down to the goatee [[GirlsWithMoustaches (even the girls)!]]
* In the Donkey Kong Jr. episode "Double Or Nothing" from ''WesternAnimation/SaturdaySupercade'' Bones' cousin Lucy Belle looks like a gender swapped version of him, Junior is quick to point this out, afterwards when Lucy Belle gets kidnapped so she won't attend the meeting for her uncle's will Junior has Bones dress up as her to take her place.

* A common FanFic trope in crossovers is to have a two different characters in [[IntercontinuityCrossover different continuities]] played by the same actors 'turn out' to be related to each other. There is one where Film/JamesBond (Creator/SeanConnery version) is the illegitimate son of [[Franchise/IndianaJones Henry Jones Jr]] and thus the grandson of [[Film/IndianaJonesAndTheLastCrusade Henry Jones Sr]]... who was played by Connery.
** There is also one used in fan fiction with [=MacGyver=] (of ''Series/MacGyver'') and Colonel Jack O'Neill (of Stargate SG-1), both played by Richard Dean Anderson, being cousins.
*** Suggesting, of course, that both are descended from [[Series/{{Legend}} dime novelist Ernest Pratt]].
* Although they were only cousin, King George V of England and the Czar Nicolas II looked like twins. [[http://en.wikipedia.org/wiki/File:Tsar_Nicholas_II_&_King_George_V.JPG See for yourself.]] George has blue eyes but that probably won't be much help.
** And George's grandson [[http://en.wikipedia.org/wiki/Prince_Michael_of_Kent Prince Michael of Kent]], who's still around today, has the same uncanny resemblance to the Tsar, to the extent that he's very popular among royalists in Russia. It helps that he grew the Russian-style beard to hide a scar, and that he's named after [[http://en.wikipedia.org/wiki/Grand_Duke_Michael_Alexandrovich_of_Russia Nicholas II's younger brother]].
* In ''AudioPlay/BigFinishDoctorWho's'' audio dramas, India Fisher plays Eighth and Sixth Doctor companion Charley Pollard. Fisher also voiced Charley's sister Cissy in the ''Gallifrey'' spin-off series.
* Outside of their trademark costumes, Groucho, Harpo, Chico, and Zeppo Marx bore an incredible resemblance to each other. They would even occasionally play each other's parts in their stage shows with no one the wiser. This is part of why the much-loved MirrorRoutine was so successful; in the same outfit, Groucho and Harpo are practically identical.
** This ended in a SugarWiki/MomentOfAwesome -- on the game show ''Series/IveGotASecret'', Harpo once appeared as the contestant, with his brother Groucho as one of the panelists. Nobody, Groucho included, could guess Harpo's secret. [[note]]The secret was that it was really Chico Marx dressed as Harpo.[[/note]]
** Reportedly this exchange happened between a Marx Brothers fan and an out-of-makeup Groucho who just wanted a quiet lunch alone:
--->'''Interrupting Fan''': Are you ''Harpo Marx?''
--->'''Irritated Groucho''': No, are you?
* Actors Alan Hale (Senior) and Alan Hale (Junior). One played Little John in ''Film/TheAdventuresOfRobinHood'', the other is famed as the Skipper on ''Series/GilligansIsland''. Without looking at the date of their films there is no way to tell them apart.
* Back in TheNineties, a [[RunningGag running joke]] was that the public appearances of Music/MichaelJackson were actually his sister [=LaToya=] Jackson.
* In the Bouguereau painting Charity, it is not possible to tell which baby is Yeshua and which one is Yochanan, since he painted them to look identical, even though they are cousins and 6 months apart. In most other paintings of them, he not only makes the age difference apparent, but has them wear different colored clothing and have different colored hair.
* An old story goes that when a Roman emperor was touring their conquered area in Jerusalem his guards noticed a local man who bore a striking resemblance to the emperor. As a joke they brought them together. The emperor thought this was funny and asked the man "Has your mother ever been to Rome?" The man replied "No, but my father has."
** The original version of this joke was supposedly told about Julius Caesar in Gaul (modern day France) seeing a man who looked very similar to himself before continuing in exactly the same way.
* Half-brothers Napoleon III and Charles de Morny looked incredibly alike; slap some hair on top of Morny's bald head and you had a spitting image of the Emperor.
* One Restoration poem is told from the point of view of a man who knows that his wife is flagrantly unfaithful. One day he asks her to explain why all the children look like him. She explains that she is very careful to be unfaithful to him only when she is already pregnant.
* Once a Victorian lady had safely produced an heir and a spare, it was socially acceptable for her to engage in a discreet affair. As a consequence, one lady remembered being sent off for her Season with one piece of advice, "Never comment on a likeness" -- for a third son or the like, who might easily not look like the older half-siblings. One lady was indeed furious that the wife of the man she had an affair with had a child that looked just like him.
