* AbilityOverAppearance: Rosie O'Donnell, though not the immediate choice for Betty, mastered her laugh and other mannerisms in her audition.
** Jane Krakowski's Betty in the prequel was slightly more well-received.
* ActorAllusion: In "Christmas Flintstone," Creator/MelBlanc voices Fred's easily irritated boss that fires him and immediately hires him back. Blanc even uses the same voice as [[TheJetsons Mr. Spacely]].
-->"FLINTSTONE! You're fired!"
** Possibly unintentional, but Gazoo's references to Fred as "dum-dum" bring to mind the fellow Alan Reed-voiced Hanna-Barbera character, Dum Dum, from the ''Touché Turtle'' cartoons.
* AllStarCast: John Goodman, Creator/RickMoranis, Rosie O'Donnell, Elizabeth Perkins, Creator/HalleBerry, and Kyle [=MacLachlan=] to name a few for the live-action film.
** Not to mention Creator/ElizabethTaylor (in what turned out to be her final big-screen movie[[note]]and other than the 2001 MadeForTVMovie ''These Old Broads'', her final movie full stop[[/note]]).
* AwesomeDearBoy: John Goodman on playing Fred Flintstone.
* DoingItForTheArt: As hard as it is to imagine, the first live action movie. For starters, unless they got John Goodman to play Fred, they wouldn't have even bothered trying to make a movie.
* HeyItsThatVoice:
** Fred Flintstone was voiced by Alan Reed. He is also known to Disney fans for playing Boris in ''Disney/LadyAndTheTramp''.
** Wilma Flintstone was voiced by Jean Vander Pyl. She also played Winsome Witch, Maw & Floral Rugg, and [[WesternAnimation/TheJetsons Rosie the Robot Maid]].
** Barney Rubble was voiced by Creator/MelBlanc, except for part of the 1961/62 season, when Creator/DawsButler substituted (see TheOtherDarrin below).
** Betty Rubble was voiced by Bea Benaderet (1960-1964) and Gerry Johnson (1964-1966). Benaderet is also known for playing [[Radio/TheJackBennyProgram Gertrude Gearshift]], [[Series/PetticoatJunction Kate Bradley]], and [[Series/TheBeverlyHillbillies Pearl Bodine]]. Johnson was better known for theatrical roles in the Dallas Theater Center.
** Comedienne Mitzi [=McCall=] (who with husband Charlie Brill were game show staples of the 1970s) voiced Penny on ''WesternAnimation/ThePebblesAndBammBammShow.'' Mitzi and Charlie had the bad fortune to be the act following Music/TheBeatles on ''Series/TheEdSullivanShow'' on February 9, 1964 (the boys' first appearance on American TV).
** [[Series/TheCarolBurnettShow Harvey]] [[Film/BlazingSaddles Korman]] played the Great Gazoo in the series, and Chief Boulder in ''The Man Called Flintstone''.
*** Korman voiced the Dictabird in ''Film/TheFlintstones'' and played Colonel Slaghoople in ''Film/TheFlintstonesInVivaRockVegas''.
** Also from TheMovie, Creator/PaulFrees as Rock Slag and Triple X, and Creator/JuneForay as Tanya, the Green Goose's #2.
** The Mexican Spanish dub deserves an special mention: Fred (and also Barney for a few episodes) in the original TV series was dubbed by Mexican comedian and actor Jorge Arvizu, who also voiced WesternAnimation/BugsBunny and [[Series/GetSmart Maxwell Smart]] and he's maybe the most iconical of all the voice actors who voiced Fred in Mexico. In other animated incarnations, he's voiced by Arturo Mercado (Anime/SpeedRacer and [[Disney/TheLionKing Simba]]) who was the second most know voice actor for Fred in Spanish and he also reprised that role in the live-action film. Creator/HumbertoVelez ([[WesternAnimation/TheSimpsons Homer Simpson]]) also voiced Fred in the ''I Yabba-Dabba Do!'' direct-to-video film. Barney was voiced by Julio Lucena (who voiced WesternAnimation/TopCat, [[WesternAnimation/WackyRaces Dick Dastardly]], and WesternAnimation/HongKongPhooey), in other animated adaptations and in the film, he's voiced by Francisco Colmenero (who voiced [[Disney/TheLionKing Pumbaa]]) and in the ''I Yabba-Dabba Do!'' direct-to-video film, Alfonso Obregon ([[Manga/{{Naruto}} Kakashi Hatake]] and WesternAnimation/{{Shrek}}) voice him too.
** In Japan, [[Creator/ToruOhira Fred]] is [[Anime/ScienceNinjaTeamGatchaman Dr. Nanbu]] and curiously enough, [[WesternAnimation/TheSimpsons Homer Simpson]] in the TV series. In the film, [[Creator/TesshoGenda he's]] [[Manga/{{Naruto}} Kurama]] and [[VideoGame/SengokuBasara Takeda Shingen]]. Barney was [[Manga/GeGeGeNoKitaro Medama Oyaji]] in one of the TV series and in the film, [[Creator/KeiTomiyama he's]] [[Anime/LegendOfGalacticHeroes Yang Wenli]]. Wilma is [[Anime/{{Doraemon}} Nobita Nobi]] and [[Anime/SuperDimensionFortressMacross Claudia LaSalle]] and in the film, she is [[Anime/CowboyBebop Julia]].
* NoExportForYou: At least in syndication -- an episode in which the Flintstones encounter a group of stereotypical Wild West Indians was successfully banned from broadcast in Saskatchewan after protests from Native American groups. The ban became moot when the show began airing on nationally broadcast cable networks and came out on DVD, however.
* OldShame: The ''Flintstones'' cast promoted [[http://www.youtube.com/watch?v=NAExoSozc2c Winston cigarettes]] during the show's first two seasons. Amusingly, those ads are now among the ''only'' vintage tobacco commercials that one can easily find online (since showing them is technically illegal just about everywhere on the planet).
* TheOtherDarrin: Hanna-Barbera voice actor Daws Butler replaced Mel Blanc as Barney Rubble for a few episodes in 1961 while Blanc was hospitalized after a near-fatal car accident. Hanna-Barbera, however, did not publicly acknowledge this, and Blanc was still listed in the closing credits. There was one episode where it started with Daws Butler as the voice of Barney and right in the middle of the episode, he's replaced with Mel Blanc (and, unlike most modern shows where there would be a fourth wall-breaking joke about it, this mistake slipped by completely unnoticed).
** Post-show examples. At this point, all of the original ''Flintstones'' actors, except for John Stephenson (the voice of Mr. Slate), have died and been replaced (some multiple times).
*** Gerry Johnson replaced Bea Benaderet as Betty Rubble in the show's fifth and sixth seasons, when Benaderet left to concentrate on her role as Kate Bradley on ''Series/PetticoatJunction''. Johnson died soon after ''The Flintstones'' ended its ABC run and would be replaced in 1971 by Gay Hartwig (Benaderet herself died in 1968, during ''Petticoat'''s run). Hartwig herself would be replaced by [[Creator/BJWard Betty Jean Ward]], who was replaced by current voice Music/GreyDeLisle.
*** Alan Reed lent his voice to Fred for the final time in the debut episode of ''[[WesternAnimation/LaffALympics Scooby's All-Star Laff-A-Lympics]]'' in 1977. He died soon after and would be replaced by Henry Corden. Corden died in 2005 and was replaced by Creator/JamesArnoldTaylor (who, according to the documentary, ''Film/IKnowThatVoice''[[note]]centered on the past and present voice actors a lot of cartoon, anime, and video game fans are familiar with, like Creator/JohnDiMaggio, Creator/MelBlanc, Creator/JimCummings, Creator/TressMacNeille, Creator/CharlieAdler, Creator/CarlosAlazraqui, Creator/CreeSummer, Creator/TaraStrong, Creator/TomKenny and Music/GreyDeLisle[[/note]], almost wasn't chosen because he didn't look like someone who'd be able to do an accurate Fred Flintstone impression. Henry Corden urged the producers to give Taylor a chance, and that's how he was picked).
*** Aside from the aforementioned period of recuperating from his car wreck, Mel Blanc voiced Barney up to his death in 1989. Since then, Barney has been played variously by Creator/FrankWelker and Jeff Bergman (and Creator/SethMacFarlane in parodies shown on ''WesternAnimation/FamilyGuy'' and ''WesternAnimation/RobotChicken'').
*** Jean Vander Pyl was the longest-surviving female member of the principal cast, playing Wilma until her death in 1999. Since then, Wilma has been played by Creator/TressMacNeille.
*** In ''The Flintstones & WWE: Stone Age SmackDown'', John O'Hurley replaced John Stephenson as the voice of Mr. Slate.
** The 2nd movie recasts all the characters due to taking place before Fred and Barney were married to Wilma and Betty.
* OutlivedItsCreator: ''The Flintstones & WWE: Stone Age SmackDown'' (2015) is the first original Flintstones production since ''On The Rocks'' in 2001... and the first to not involve the original creators (who passed away in 2001 [Hanna] and 2006 [Barbera]). This was also the first time in nearly 50 years that Mr. Slate was voiced by someone other than John Stephenson.
* RecycledScript: There have been numerous episodes where Fred had a doppelgänger and in a TV movie from the 1970s, Fred took Santa's place. He did the same thing in the original show.
* RecycledSoundtrack: In a sense. Mel Blanc's previously-recorded yaps for Dino from the original series were re-used for the films. Blanc himself had been dead for five years by the time the first film was released, and his voice was initially used without a screen credit, prompting his estate to slap the studio with a lawsuit before one was put in for the home video release.
** Several Hanna-Barbera series from around the same time used the show's stock music, most notably ''The Yogi Bear Show''[[note]]A couple episodes of which even have what would later become "Meet The Flintstones" snuck into the music.[[/note]]
* ThrowItIn:
** The script for the first episode had Fred saying "yahoo". Alan Reed didn't like it, and asked whether he could change it to "Yabba-dabba-doo".
** Barney's VocalEvolution came about when Mel Blanc suffered brain damage in a car accident. When he came back to work, he suddenly started using that deeper voice for Barney (which was also a much closer imitation of [[Series/TheHoneymooners Art Carney]]'s voice - even though Blanc had originally refused to ape Carney) and no one said anything.
* WhatCouldHaveBeen:
** At one point, Creator/RichardDonner was attached to direct, Joel Silver was going to produce and Jim Belushi was going to play Fred. When the movie went from Warner Bros. to Universal, Donner stayed around but had to pull out due to conflicting schedules with ''Film/{{Maverick}}''.
** Former ''Series/SaturdayNightLive'' cast members Creator/BillMurray, Creator/DanAykroyd, and Creator/ChevyChase were all considered for the role of Fred, but they were all deemed too skinny, and putting any of them in a fat suit would look too inappropriate.
** Creator/JohnCandy audtioned for the role of Fred.
** Creator/DannyDeVito was Spielberg's original choice for the role of Barney. [=DeVito=] refused and recommended Rick Moranis for the part.
** The role of Sharon Stone the secretary was written for...Sharon Stone, but due to scheduling conflicts with ''Film/TheSpecialist'', she dropped out and Halle Berry signed on.
*** They tried to change her name to Rosetta Stone, but [[ExecutiveMeddling the studio thought]] [[ViewersAreMorons people wouldn't get the reference]].
** Janine Turner was considered for the role of Betty.
** Fred and Wilma were originally to have had a son, Fred, Jr. He was cut from the show's final series' bible, but a Golden Book that was based on the original ideas was released just as the show debuted. Maybe Pebbles' older brother ran off with the original, intelligent Dino?
** Jackie Gleason was not happy about learning that Fred Flintstone was based on him without his permission, nor that the Flintstones was based on his old TV series ''Series/TheHoneymooners'' and tried to file a lawsuit for using his likeness, but friends and colleagues dissuaded him from doing so in light of the show's popularity, telling him it would be bad for his reputation if he became known as "the man who killed Fred Flintstone."
** Creator/SethMacFarlane was originally going to revive the show for FOX, possibly as a replacement for ''WesternAnimation/TheSimpsons'', which was about to be canceled in the middle of season 23 due to money issues[[note]]the last episode would have been the ChristmasEpisode in the future where Bart tries to bond with his kids while divorced from Jenda while Lisa tries to bond with her teenaged daughter and Maggie is pregnant[[/note]]. Fortunately (or not, depending on who you ask), [=MacFarlane=] shelved the show after the cast and crew of ''The Simpsons'' took a pay cut to keep the show afloat.
*** The ''real'' reason this Flintstones project got shelved is because FOX and Warner Bros. could not agree on profit negotiations.
