''The Flintstones in Viva Rock Vegas'' is the second LiveActionAdaptation of ''WesternAnimation/TheFlintstones'' franchise. It's a {{Prequel}} to [[Film/TheFlintstones the first film]] in which Fred Flintstone (Creator/MarkAddy) and Barney Rubble (Stephen Baldwin) meet Wilma Slaghoople (Kristen Johnston) and Betty O'Shale (Jane Krakowski), respectively. The film outlines how both couples fell in love and the rivalries from others that complicated their relationships. Joining in is the mysterious little alien the Great Gazoo (Creator/AlanCumming) who has been sent to Earth to experience humanity's "mating rituals"--though only Fred and Barney are able to see him. Nothing will stand in the way of love-- except for arrogant and conniving playboy Chip Rockefeller (Thomas Gibson), who has made it in the cutthroat town of Rock Vegas and wants to marry Wilma only for her family's fortune in order to pay off his own debts and keep his own wealth.

Despite slightly more positive reception than the first film (though still generally negative), this film had the misfortune of coming out during a time when Creator/HannaBarbera cartoons had become SoLastSeason, and Universal Pictures was already exhausting their advertising expenditures toward two of their other films released that same period, ''Film/{{U571}}'' and ''Film/{{Gladiator}}''. As a result of being put on their self-made blockbuster death row, ''Viva Rock Vegas'' tanked at the box office, grossing far less than its predecessor, and Universal relinquished the Hanna-Barbera film license[[note]]though they would keep it until production wrapped up for ''Film/JosieAndThePussycats'', which later bombed as well[[/note]], resulting in [[FranchiseKiller no further]] live-action ''Flintstones'' movies being made since then, though an animated film currently ''is'' in development by [[Creator/WarnerBros Warner Animation Group]].

* AcquiredSituationalNarcissism: When Fred starts winning big at the casino (actually the work of Chip behind the scenes), he briefly acts like a posh jerk, thinking that's what Wilma wants. He's very wrong.
* AllPowerfulBystander: Gazoo. He can do pretty much anything he wants by snapping his fingers, but his overseers forbid him from using his powers while on Earth except for his research purposes. One of the sweeter moments in the movie is he when [[ScrewTheRulesImDoingWhatsRight decides to help Fred and Barney escape jail anyway]].
* AlternateContinuity: Not only does the movie re-tell the story of how Fred and Barney met Wilma and Betty, it also has a different origin story for Gazoo - in the cartoon, he was banished because he invented a doomsday machine, but here he's part of a race of galactic observers, and is sent to Earth in order to study the human concept of love and romance (and because he apparently can't keep his nose out of other people's business).
* BigEater: Barney.
* BreakingTheFourthWall: Gazoo is able to do this; at the beginning of the film, he points out the giant letters of the Universal logo orbiting the Earth, and at the end, he snaps his fingers to SmashToBlack.
* TheCameo: The creators of the original Flintstones cartoon, William Hanna and Joseph Barbera, can be seen briefly [[spoiler: during Fred and Wilma's wedding]].
** In addition, Harvey Korman (the voice of the Great Gazoo from the cartoon) plays Colonel Slaghoople; the voice of Mr. Slate is the minister at [[spoiler: the wedding]]; and Rosie O'Donnell, who played Betty in the first movie, voices an octopus masseuse for a few lines.
* CompanionCube: Wilma's pearl necklace. The film reveals that they were a gift from her father, who gave them to her while promising that no matter what she chose to do with her life, he would love and support her.
* DaddysGirl: Wilma--the only way her mother is able to get her to return to the mansion is by pointing out how upset Colonel Slaghoople would be if his daughter didn't show up to his birthday party.
* DiabolusExMachina: How Chip gets Fred into debt: The former literally has a hidden switch that [[AWizardDidIt somehow]] affects Fred's luck.
* DisguisedInDrag: How Fred and Barney get around hotel security after Gazoo helps them escape from jail--they pass themselves off as showgirls.
* DoesNotLikeShoes: As usual for the ''Flintstones'' franchise, but it's {{Lampshaded}} here.
-->'''Fred:''' Was that an insult?\\
'''Gazoo:''' If the shoe fits...\\
'''Barney:''' What's a shoe?\\
'''Gazoo:''' ...Okay, it ''was'' an insult.
* DoomedByCanon: Any fan of ''The Flintstones'' should know from the very beginning Chip [[spoiler:wouldn't get Wilma]].
* EngineeredPublicConfession: Chip deliberately creates one of these by planting Wilma's beloved pearl necklace in Fred's pocket, then announcing that a robbery has been committed and encouraging the thief to step forward. Unfortunately, [[RuleOfThree three other patrons]] think he's talking about them and make confessions of their own.
-->'''Towel Confessor Woman''': I STOLE ALL THE TOWELS FROM MY ROOM!
-->'''Chip''': ...Yes, well, technically that is illegal, but...
-->'''Underwear Confessor Guy''': I'M WEARING SOMEONE ELSE'S UNDERWEAR! ''(the crowd recoils in disgust and backs away from him)''
-->'''Chip''': No! I was talking about--
-->'''Dinosaur Confessor Guy''': I'm systematically poisoning the dinosaurs' water supply! In a matter of decades, their entire species will be extinct! ''(the crowd laughs)''
-->'''Chip''': ALRIGHT! This is obviously going nowhere.
* EverybodyCries: After getting sent to jail, Fred and Barney break down crying over losing Wilma and Betty respectively. Gazoo tries to calm them, claiming that the alien race he comes from had gone for ages without expressing emotions, but it's not long before he joins in with the crying too.
* GettingCrapPastTheRadar: When Chip announced that somebody at his casino did something horrible, a man asked the girl at his side to confirm her age.
* GilliganCut: Two:
-->''(After Gazoo is banished to Earth)''
-->'''Alien Leader''': Imagine the ''moron'' that's going to get stuck with Gazoo!
-->''(Cut to a shot of Fred driving his car)''
** And later:
--->'''Wilma''': I don't think there's a greedy bone in Fred's body.
--->''(Cut to Fred tossing money in the air at a gambling table)''
--->'''Fred''': YABBA-DABBA-DOUGH!
* GoldDigger: Chip only wants Wilma for her family's wealth.
* MistakenForCheating: When Betty sees Barney removing cream from a showgirl's chest, she thinks he's making a pass at the girl.
* MistakenForGay: When Fred and Barney get tuck themselves in their bunk bed, Gazoo suddenly appears and startles them. It startles Barney so much that he falls out of his top bunk and he lands on top of Fred, making Gazoo believe they're mating (doesn't help that Gazoo's alien race has no females and they reproduce like amoebas). Talk about a [[{{Pun}} gay old time]]!
-->'''Fred''': What are you doing here?\\
'''Gazoo''': I'm here to experience your species' mating rituals, so get to it!\\
'''Fred''': Oh, no, Barney and me don't, uh... Get off of me! (''shoves Barney off his back and onto the floor'')
* MistakenForServant: Wilma's mother mistakes Betty for a housekeeper when she first meets her.
* ObnoxiousInLaws: Like in the original series, Wilma's mother dislikes Fred.
* OneGenderRace: The alien race Gazoo comes from, all of whom are male - they don't understand the concept of 'mating' because they reproduce like amoebas.
* PteroSoarer: An [[VisualEffectsOfAwesome admittedly cool looking]] pterosaur acts as an airplane for the appropriately titled "Pterodactyl Airlines".
* RealityWarper: Gazoo. When he finally decides to break the rules and help Fred and Barney, all he needs to do is say "Achoo!" to activate telekinetic abilities and take out a troublesome guard.
* TheReasonYouSuckSpeech: Wilma delivers an epic one to her mother after the latter screams at Fred for ruining her party. '
-->'''Wilma''': ''How can you treat people this way?''
* RichSuitorPoorSuitor:
** Chip Rockfeller and Fred Flintstone. Somewhat subverted in that Chip's wealth was a mere facade and he needed to marry Wilma for her family's money or then he'd lose his estate and then some to pay his debts.
** Also, [[Music/TheRollingStones Mick Jagged]] and Barney Rubble. Albeit, in that case, it was more about Mick being famous than being rich.
* ScrewTheMoneyIHaveRules: Chip offered to release Fred from his gambling debts if Fred agreed to leave Wilma. Fred refused.
* SlobsVersusSnobs: The scene between the wealthy elite at Colonel Slaghoople's birthday party and Fred, Barney, and Betty, the "commoners."
* TrappedByGamblingDebts: [[RichSuitorPoorSuitor Chip Rockfeller and Fred Flintstone]] were rivals for Wilma's affections. Rockfeller lured Fred into a casino of his, where Fred got a debt of 1.4 million clams. Rockfeller then offered to cancel the debt if Fred agreed to get out of Wilma's life forever. When Fred refused, Rockfeller stole Wilma's pearl necklace and framed Fred, claiming Fred intended to sell the necklace to pay his debt.
* UptownGirl: Upon learning about Wilma's financial status, Fred felt the trope's weight and feared not to be good enough for her. That helped Chip on his plan to get rid of Fred.
* WidelySpacedJailBars: At one point, Fred and Barney are in a jail. While the bars are close enough together to give Fred trouble, Barney can walk through the gaps without even shrugging. He doesn't realize this until he, Fred, and Gazoo start crying; Barney walks out of the cell to get the tissues on a guard's desk, then ''goes back in with them.'' Fred actually has to tell him to go back out and get the keys.
