History Trivia / TheSimpsons

* CreativeDifferences: Klasky-Csupo company animated the shorts from ''Series/TheTraceyUllmanShow'' and the first 63 episodes. Gabor Csupo wasn't pleased when Gracie Films demanded they put one of their own producers to oversee the animation and production since then shifted to Film Roman, with Klasky-Csupo moving on to create ''WesternAnimation/{{Rugrats}}''.

** In France, after season 3 ended on October 10, 1992, Canal+ completely cancelled the show temporarily and didn't show reruns of it. Instead, ''The Simpsoms'' was replaced with ''WesternAnimation/Rugrats1991'' the following week. The series was off the air in France for a while, and might have not come back until September 1993.

* TheDanza: Doris Grau did the voice of Lunchlady Doris. Also a case of DescendedCreator due to Grau working as a script supervisor from 1989 to 1993.

* ChildrenVoicingChildren: So far, there have only been two instances of child characters being voiced by actual children in the series. The first was with Bart's teenage love interest [[Recap/TheSimpsonsS4E8NewKidOnTheBlock Laura Powers]], who was voiced by then 16 year old Sara Gilbert. The second was with Bart's unofficially adopted brother [[Recap/TheSimpsonsS21E8OBrotherWhereBartThou Charlie]] who was voiced by then 9-year old Jordan Nagai.

*** Creator/KevinMichaelRichardson will be taking over for Harry Shearer as the new Dr. Hibbert.

* CrossDressingVoices: Probably the most famous example in modern American animation: Creator/NancyCartwright as Bart Simpson (and most of his male classmates as well, like Ralph Wiggum, Nelson Muntz, Todd Flanders, and Kearney Zzyzwicz[[note]]the bald bully who's actually somewhere in his 20s to 30s, yet looks high school-aged and has been held back in elementary school for years[[/note]]). Other examples include: Pamela Hayden as Jimbo Jones, Milhouse van Houten, and Rod Flanders; Russi Taylor as Martin Prince and Uter the German exchange student; Tress [=MacNeille=] as Dolph[[note]]the bully with red hair who hangs with Jimbo and Kearney[[/note]]; and Jo Ann Harris as the first voices of Wendell the sick kid and Bart's nondescript friends from the early episodes, Richard and Lewis.
** Averted in some languages (Brazilian Portuguese, Czech and Hungarian), where Bart has a male voice actor (however, in the Czech dub at least this trope is still present, because Marge is voiced by a male actor also).

** Fat Tony is usually voiced by Joe Mantegna, however in "[[Recap/TheSimpsonsS7E19AFishCalledSelma A Fish Called Selma]]" he was voiced by Creator/PhilHartman[[note]]The producers didn't contact Joe Mantegna because they thought he wouldn't be willing to come in to record such a small role. Mantegna got in touch afterwards saying that he enjoys playing Fat Tony so much that he'll always make time for the character.[[/note]].

*** Mrs. Glick, an elderly woman from the Simpsons' neighborhood, was originally played by Cloris Leachman (in "[[Recap/TheSimpsonsS2E21ThreeMenAndAComicBook Three Men and a Comic Book]]") and then by Creator/TressMacNeille.

*** Beginning with "Now Museum, Now You Don't", Bumblebee Man (also originally voiced by Azaria) would be voiced by Eric Lopez, who is Cuban-American.

** After the show, along with 21st Century Fox's entertainment assets, were acquired by The Walt Disney Company, showrunners have stated that Disney has been very supportive of the show, including ideas for more movies and spin-off series. Creator/DisneyPlus also heavily highlights and markets the show as one of their biggest marquee titles, and the short lived theatrical release of ''WesternAnimation/{{Onward}}'' [[WesternAnimation/MaggieSimpsonInPlaydateWithDestiny came with a Simpsons short proceeding it.]]

* CelebrityVoiceActor: The show has had many celebrity voice actors in its 30-year run due to its immense popularity. Because of how long it would take to list every single occurence of this in the show, a general rule of thumb is that if there's a popular celebrity out there and they've done some voice acting, at least one of those roles (or in some cases, their only role) with be a spot on The Simpsons. This is probably because it's seen as a status signal in the world of celebrities, as it shows that the person in question has become a staple of pop culture. This trend has also influenced similar animated shows aimed at adults, including several aired by Creator/{{FOX}} such as the animated shows by Creator/SethMacFarlane, ''WesternAnimation/KingOfTheHill'' and ''WesternAnimation/BobsBurgers'', and even to some on other networks like ''WesternAnimation/RickAndMorty'' and ''WesternAnimation/BojackHorseman''.
* [[TheCharacterDiedWithHim The Character Died With Her]]: In the episode "[[Recap/TheSimpsonsS25E13TheManWhoGrewTooMuch The Man Who Grew Too Much]]", Edna Krabappel was stated to have died following the death of Marcia Wallace. After Ned Flanders' dream about him and Edna doing the tango, he looks at the picture of Edna and remarks sadly, "I sure do miss that laugh." Nelson the school bully replies "Ha-ha! [[MoodWhiplash I miss her, too]]."

** Lesbian actress Fortune Feimster plays Evelyn, Patty's girlfriend.

* IKnewIt:
** Many fans on the Internet correctly predicted that the character who would die in "[[Recap/TheSimpsonsS26E1ClownInTheDumps Clown in the Dumps]]" would be [[spoiler: Krusty's dad Rabbi Krustofski]], since this show doesn't have the guts to kill off a major character (unless the voice actor quit or died and a replacement can't be found).
** Similarly, a lot of fans figured out that Patty would be the character who'd come out as gay in [[Recap/TheSimpsonsS16E10TheresSomethingAboutMarrying "There's Something About Marrying"]].

** Harry Shearer [[https://www.dailymail.co.uk/news/article-8590717/The-Simpsons-actor-calls-shows-decision-stop-having-white-actors-play-POC-characters.html vocally criticized]] the decision to [[TheOtherDarrin recast all non-white characters with people of color]], noting that a major point of acting is being able to play characters outside the actor's natural range.

*** Rosalie Chiang ("Mei Mei" from ''WesternAnimation/TurningRed'') will take over from [=MacNeille=] as Hubert Wong.

** Starting with both ''WesternAnimation/TheGoodTheBartAndTheLoki'' and season 15 onwards at 2023, the Japanese dub's entire cast was replaced due to both Creator/ToruOhira, Homer's first voice actor, passing away and the fact most of the voice actors of many characters, including those from the titular family, excluding Maggie, are already too old to keep voicing them anymore. The only voice actor from the previous seasons who still reprise his role is Creator/MitsuruOgata as Mr. Burns.

* BreakthroughHit: For adult animation in the United States, following a multi-decade hiatus. On a smaller scale, it marked Creator/MattGoening's breakthrough. It was also one of two for the Fox network, the other being ''Series/MarriedWithChildren''.

* BreakthroughHit: For adult animation in the United States, following a multi-decade hiatus.

** Both Julio and his second actor tony Rodriguez are gay.

* QueerCharacterQueerActor: Creator/ScottThompson, who is gay, plays Grady in "Three Gays of the Condo", "Homer and Lisa Exchange Cross Words", "Flaming Moe" and "Werking Mom".

* QueerCharacterQueerActor: Scott Thompson plays Grady in "Three Gays of the Condo", "Homer and Lisa Exchange Cross Words", "Flaming Moe" and "Werking Mom".

* UnfinishedDub: The Japanese dub stopped at season 14 after Creator/ToruOhira, Homer's voice actor, died; this is later subverted, as Disney Plus continued the dub at 2023, through with a newer voice cast.

** With Marcia Wallace's death in October 2013, the producers announced that Mrs. Krabappel would be retired once the remaining episodes Wallace had recorded aired. They eventually decided that [[TheCharacterDiedWithHim Mrs. Krabappel died as well]], both out of respect for Wallace and because it would have been awkward to explain her absence from scenes involving the school or Ned Flanders.
