The Flintstones in Viva Rock Vegas is the second Live-Action Adaptation of The Flintstones franchise. It's a Prequel to 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 Hanna-Barbera cartoons had become So Last Season, and Universal Pictures was already exhausting their advertising expenditures toward two of their other films released that same period, U571 and 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 licensenote , resulting in no further live-action Flintstones movies being made since then, though an animated film currently is in development by Warner Animation Group.
- Acquired Situational Narcissism: 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.
- All-Powerful Bystander: 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 decides to help Fred and Barney escape jail anyway.
- Alternate Continuity: 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).
- Big Eater: Barney.
- Breaking the Fourth Wall: 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 Smash to Black.
- The Cameo: The creators of the original Flintstones cartoon, William Hanna and Joseph Barbera, can be seen briefly 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 the wedding; and Rosie O'Donnell, who played Betty in the first movie, voices an octopus masseuse for a few lines.
- Companion Cube: 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.
- Daddy's Girl: 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.
- Diabolus ex Machina: How Chip gets Fred into debt: The former literally has a hidden switch that somehow affects Fred's luck.
- Disguised in Drag: How Fred and Barney get around hotel security after Gazoo helps them escape from jail—they pass themselves off as showgirls.
- Does Not Like Shoes: 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.
- Doomed by Canon: Any fan of The Flintstones should know from the very beginning Chip wouldn't get Wilma.
- Engineered Public Confession: 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, 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.
- Getting Crap Past the Radar: When Chip announced that somebody at his casino did something horrible, a man asked the girl at his side to confirm her age.
- Gilligan Cut: 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!
- And later:
- Gold Digger: Chip only wants Wilma for her family's wealth.
- Mistaken for Cheating: When Betty sees Barney removing cream from a showgirl's chest, she thinks he's making a pass at the girl.
- Mistaken for Servant: Wilma's mother mistakes Betty for a housekeeper when she first meets her.
- Obnoxious In-Laws: Like in the original series, Wilma's mother dislikes Fred.
- One-Gender Race: The alien race Gazoo comes from, all of whom are male - they don't understand the concept of 'mating' because they reproduce like amoebas.
- Ptero Soarer: An admittedly cool looking pterosaur acts as an airplane for the appropriately titled "Pterodactyl Airlines".
- Reality Warper: 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.
- "The Reason You Suck" Speech: 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?
- Rich Suitor, Poor Suitor:
- 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, Mick Jagged and Barney Rubble. Albeit, in that case, it was more about Mick being famous than being rich.
- Screw the Money, I Have Rules!: Chip offered to release Fred from his gambling debts if Fred agreed to leave Wilma. Fred refused.
- Slobs vs. Snobs: The scene between the wealthy elite at Colonel Slaghoople's birthday party and Fred, Barney, and Betty, the "commoners."
- Trapped by Gambling Debts: 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.
- Uptown Girl: 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.
- Widely Spaced Jail Bars: 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.
