!!For the franchise as a whole:
* AdaptationSequence: Newspaper Comic > TV show > Cartoon > Video Game > Movie > TV show loosely based on movie > Video Game > Sequel to movie > Broadway Musical
* BeamMeUpScotty: Morticia is often quoted saying, "Normal is an illusion. What's normal for the spider is chaos for the fly." However, no one is sure ''when'' exactly she said that.
** She does say the line in TheMusical, but it seems to be a reference to the presumed earlier quote.
* KeepCirculatingTheTapes: To this day, there has never been a [=DVD=] release for the following Addams Family films and shows: ''The Addams Family Fun-House'', ''Halloween with the New Addams Family'', the 1992 animated series, ''Addams Family Reunion'', and -- at least in America -- ''The New Addams Family''.
* TropeNamers
** MadeFromRealGirlScouts: The only Girl Scout cookies Wednesday will buy.
** OneNormalNight: From the song of the same name in the 2010 Broadway musical, where Wednesday, hoping to set a good impression with her fiance and his family, requests that the Addams clan try to behave like average human beings. As expected, [[spoiler: they can't]], and HilarityEnsues.
* WhatCouldHaveBeen: After Illumination Entertainment obtained the rights to Charles Addams' original cartoons, there was a planned stop-motion animated film with Creator/TimBurton calling the shots. As of July 2013, the project has been cancelled.
** [[WordOfGod According to director Barry Sonnenfeld]], in the first film, [[spoiler:Gordon Craven ''wasn't'' supposed to have been Fester all along, but still an imposter, though the family would've accepted him as Fester anyway, as, in Sonnenfeld's words, "...family wasn't about blood, it was about love."]] Sonnenfeld described Anjelica Huston as "passionately against" the idea and Raul Julia as "outraged" (though funnily enough Christopher Lloyd himself didn't care either way), and in the end, the cast chose ten-year-old Christina Ricci to convince Sonnenfeld to change the ending.

!!For the various television serieses:
* DuelingShows: With ''TheMunsters''. The Addams family were humans that acted like monsters, but the Munsters were monsters that acted like normal humans. It was an interesting contrast.
* HeyItsThatGuy: DonRickles is a thief, while [[Series/TheAddamsFamily Otis Campbell]] is a judge the Addams courtroom antics drive to drink.
* TheOtherDarrin: A sort-of example from the series: the man playing Thing occasionally used his left hand just to see if anybody would notice.
* RecycledScript: Most of the episodes of ''The New Addams Family'' were recycled from the original series. In fact, the episode "Thing is Missing" is a twofer. Not only is it a remake of an episode from the original show, but it also borrows two plot elements from the 1992 animated series episode "Itt's Over" (though this time, Uncle Fester starts growing hair because he's stressed over the mistaken belief that ''Thing'' is dead rather than Cousin Itt).
* ThrowItIn: Ted Cassidy ad-libbed "You rang?" in the pilot, and the producers kept it -- and changed Lurch from a mute to allow for it.

!!For the musical:
* HeyItsThatGuy:
** Creator/BebeNeuwirth (best know as Lilith Sternin from ''Series/{{Cheers}}'' and ''Series/{{Frasier}}'') plays Morticia.
** Nathan Lane ([[Disney/TheLionKing Timon]]) as Gomez.

!!For the animated series:
* HeyItsThatGuy:
** Wednesday was [[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy Neutron]].
** Pugsley was [[WesternAnimation/AsToldByGinger Carl Foutley]] and [[WesternAnimation/TheSuperMarioBrosSuperShow Princess Toadstool.]]
** [[Creator/JimCummings Lurch]] was {{Pete}}, WesternAnimation/DarkwingDuck, and [[WesternAnimation/SonicTheHedgehog Dr. Robotnik]].
** Cousin Itt was [[WesternAnimation/TeenageMutantNinjaTurtles1987 Krang, Baxter Stockman and Casey Jones.]]
** [[Creator/RobPaulsen Norman Normanmeyer]] was [[WesternAnimation/TeenageMutantNinjaTurtles1987 Raphael]], [[WesternAnimation/{{Animaniacs}} Yakko Warner]], and [[WesternAnimation/PinkyAndTheBrain Pinky]].

!!For the films:
* AuthorExistenceFailure: Or, rather, ''Actor'' Existence Failure: A third film in the Creator/{{Paramount}} trilogy was prepared before Creator/RaulJulia died in 1994. [[TypeCasting Since literally no one could play Gomez like him]] (not even, sadly, Creator/TimCurry), the project was scrapped.
* HeyItsThatGuy:
** In the film series, [[Film/StreetFighter M. Bison]] is Gomez, [[Film/EverAfter Baroness Rodmilla DeGhent]] is Morticia, [[Film/BackToTheFuture Doc Emmett Brown]] is Uncle Fester, [[Film/SpeedRacer Trixie]] is Wednesday, [[Series/StarTrekTheNextGeneration Mr. Homn]] [[TypeCasting (appropriately enough)]] is Lurch, and [[{{Film/Jawbreaker}} Mrs Sherwood]] is Grandmama.
*** Underneath all that hair, Cousin Itt is [[Film/ChildrenOfTheCorn1984 Isaac]].
** HilariousInHindsight: Lane played a police officer in the second film, being confronted by a raving mad Gomez appropriately enough. And [[TheJeffersons Mr. Bentley]] is Judge Womack in the first film.
** In ''Addams Family Values'', aside from the main characters, [[{{Numb3rs}} Larry Fleinhart]] and [[{{Cybill}} Maryanne Thorpe]] are sadistic camp counselors, [[{{Numb3rs}} Charlie]] is Wednesday's boyfriend, [[Film/{{Airplane}} Captain Oveur]] has apparently straightened out and is the host of ''America's Most Disgusting Unsolved Crimes'', and [[Film/{{Toys}} Joan Cusack]] is the gold digger!
*** Also in ''Addams Family Values'', [[{{Sex and the City}} Cynthia Nixon]] has a blink-and-you'll-miss-her scene as a Hippie Nanny.
*** ''Also'' also in ''Addams Family Values'', while Fester is waiting for Debbie to return at their [[spoiler:bomb-rigged]] home, Debbie is secretly at a nightclub being wooed by several men. Look closely at the Hispanic-talking one in the sailor's outfit -- that's a young [[Series/{{Monk}} Tony Shalhoub]].
*** [[OverlyLongGag ALSO also also]] in ''Addams Family Values'', [[Series/{{Frasier}} David Hyde Pierce]] is the doctor who delivers baby Pubert at the hospital at the beginning, though you can't exactly see him very well due to the surgeon's mask covering his face.
** [[Series/BuffyTheVampireSlayer Harmony]] was a "real girl scout" in the first movie and Little Miss Perfect Amanda in the second. Her father in the second film was [[Series/{{Friends}} Chandler's boss]].
** In ''Addams Family Reunion'', [[Film/TheRockyHorrorPictureShow Dr. Frank N.]] [[TimCurry Furter]] is Gomez and [[Film/{{Splash}} Madison the Mermaid]] is Morticia.
*** Wednesday in ''Reunion'' is Wednesday in ''The New Addams Family'' - Nicole Fugere was the only actor to appear in both.
* TheOtherDarrin:
** For unknown reasons, Carol Kane replaced Judith Malina as Grandmama for ''Addams Family Values''.
** The third movie did this to most of the actors playing the family. Justified, as it's intended as a separate continuity, and the only reason it exists is to have served as the PilotMovie for ''The New Addams Family''.

!!For the Bally pinball game:
* HeyItsThatSound: The sound effects played after completing a Three- and Four-Way Combo sequence are the same ones used in ''Pinball/{{Funhouse}}''.
* ReferencedBy: ''Pinball/JunkYard'' lets you access [[Pinball/TheAddamsFamily the pinball machine]]'s "Mamushka" mode through its TimeMachine.
** Music from the game can also play in ''Pinball/TheTwilightZone''[='=]s "Fast Lock" multi ball.
