* AdaptationSequence: Newspaper Comic > TV show > Cartoon > Video Game > Movie > TV show loosely based on movie > Video Game > Sequel to movie > Broadway Musical
* AuthorExistenceFailure: Or, rather, ''Actor'' Existence Failure: A third film in the Creator/{{Paramount}} trilogy was prepared before RaulJulia died in 1994. [[TypeCasting Since literally no one could play Gomez like him]] (not even, sadly, Creator/TimCurry), the project was scrapped.
* 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.
* 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:
** In the Original Series
*** DonRickles is a thief
*** [[Series/TheAddamsFamily Otis Campbell]] is a judge the Addams courtroom antics drive to drink.
** Creator/BebeNeuwirth (best know as Lilith Sternin from ''Series/{{Cheers}}'' and ''Series/{{Frasier}}'') plays Morticia in the 2010 musical.
** Nathan Lane ([[Disney/TheLionKing Timon]]) as Gomez.
*** HilariousInHindsight: Lane played a police officer in the second film, being confronted by a raving mad Gomez appropriately enough.
** 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]].
*** 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.
** [[TheJeffersons Mr. Bentley]] is Judge Womack in the first film.
** [[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 the 1992 animated series:
*** 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.]]
** 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.
* 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''.
* TheOtherDarrin: A sort-of example from the series: the man playing Thing occasionally used his left hand just to see if anybody would notice.
** For unknown reasons, in the film series, Carol Kane replaced Judith Malina as Granny for ''Addams Family Values''.
** The third movie did this to most of the actors playing the family. It's intended as a separate continuity. The only reason it exists is to have served as the PilotMovie for ''The New Addams Family''.
* RecycledScript: Most of the episodes of ''The New Addams Family'' were recycled from the original series.
* 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.
* 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.
* 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.
** It was once stated that the first live-action film was originally going to leave it ambiguous over whether Gordon Craven really was Fester or was merely an impostor who subsequently became convinced that he was Fester, but the cast agreed that it would be better if Gordon turned out to actually be Fester all along.
