'''''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 meets Wilma Slaghoople and Barney meets Betty O'Shale. The film outlines how both couples fell in love and the rivalries from others that complicated their relationships.

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 extremely less than its predecessor grossed, 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]] ''Flintstones'' movies being made since then.


* 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).
* TheCameo: The creators of the original Flintstones cartoon, William Hanna and Joseph Barbera, can be seen briefly [[spoiler: during Fred and Wilma's wedding]].
* 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]].
* GettingCrapPastTheRadar: When Chip announced that somebody at his casino did something horrible, a man asked the girl at his side to confirm her age.
* 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.
* 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".
* 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.
* 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 until an item falls just out of reach and he has to step through to get them. No, it wasn't the keys; Fred actually has to tell him to go back out and get the keys and let Fred out of the cell.
