The Flintstones in Viva Rock Vegas

Fred Flintstone (Mark Addy) and Barney Rubble (Baldwin) share a trailer while trying (unsuccessfully) to find girlfriends. They meet a little green alien called the Great Gazoo, who was exiled to Earth by his species in order to study the human mating and reproduction cycle (his own people reproduce asexually). Gazoo, whom only Fred and Barney can see, decides to follow Fred and Barney to gather information, even though his superior knowledge and personality annoys them.Wilma, meanwhile, is living in a mansion with her wealthy parents. Her control-freak mother, Pearl, thinks that her daughter's wish to do common things such as bowling are silly and wants her to marry rich smooth casino-owner Chip Rockfeller. After a fight with her mother, Wilma angrily storms out of the house and goes to a Bronto Burger King in Bedrock, where she is waited on by Betty. Betty mistakenly thinks that Wilma is a "caveless" person and offers to share her apartment with her. Wilma is also given a job at the restaurant.When Fred and Barney go to the restaurant for dinner, they are smitten with the girls and manage to talk them into going to a carnival with them. Fred goes with Betty and Barney goes with Wilma, but they later exchange girls. Wilma later takes Fred, Barney, and Betty to her father's birthday party, where Fred intends on proposing to Wilma. Once they get there, they are all shocked to find out that Wilma comes from a very wealthy family, when they all thought that she was poor, and Fred changes his mind about proposing to her after he meets Chip and realizes what he is up against.Fred and Barney humiliate themselves and Wilma at the dinner, but Wilma tells everyone that she is proud to be friends with them and they walk out of the mansion. Chip, however, devises a plan to get Wilma back by inviting the foursome to stay at his resort in Rock Vegas, believing that Fred will become caught up in gambling and Wilma will leave him. The four of them enjoy the start of their trip. Chip gives them a huge comfortable suite at his resort, and access to the pool, and spa treatment for Wilma and Betty. Fred decides to start gambling, but never bets any high amount. Chip and his girlfriend Roxie are visited by two men who reveal that Chip owes their boss a lot of money. Chip tells them that he will soon be married to Wilma and will use her family's money to pay off his debt, and Gazoo witnesses the entire conversation. Chip then invites Fred to play poker with the high rollers, and make more money, but Barney tries to prevent Fred from agreeing. Chip then tells Barney about the All-You-Can Eat buffet, and gets Roxie to seduce him into escorting her there.Fred gets caught up in gambling that he forgets that he and Barney were supposed to meet Wilma and Betty for dinner. While looking for Barney, Betty sees him wiping cream off of Roxie's chest and mistakenly believes he is touching her breast. She begins crying by a fountain and is approached by Mick Jagged, who is attracted to her. She tells him that her boyfriend was cheating on her and he comforts her, then invites her to go out on a date with him, which she accepts. Fred and Wilma get into an argument over Fred's obsession with gambling and Wilma breaks up with him. Chip then arranges to have Fred lose all of the money he won so he will be left with nothing. Wilma is walking around the resort and runs into Chip and she tells him about her breakup with Fred. He then tells her that there have been burglaries around the hotel and keeps her pearls in a safe. Fred, who has lost all his money, goes to Chip for help, and Chip puts Wilma's pearls in Fred's pocket. He then announces to the entire resort that someone has stolen the pearls, and tells Fred to empty his pockets, and shows all of the guests that Fred has the pearls. Security comes to arrest Fred and Barney as well when he tries to help Fred. Wilma and Chip get back together.While in prison, Fred and Barney are visited by Gazoo, who tells them about Chip's plan to use Wilma's wealth to pay his debt. Then once they think that they can not stop him, they realize that Barney can slip through the bars and he steals the guard's keys and unlocks the cell. The two disguise themselves as dancers and accidentally run into Jagged's dressing room and see Betty. Barney tells Betty he loves her, and they get back together. Chip proposes to Wilma just as Jagged comes on stage to sing, but once he turns around, it is revealed to be Fred. He sings to Wilma, and she realizes that she still loves him. He comes off stage and confesses his love for her and proposes to her. She rejects Chip and agrees to marry Fred. Fred and Wilma get married in the Rock Vegas Chapel of Love. Mick Jagged sings "Viva Rock Vegas" at a party. Wilma throws back her bouquet of flowers and Betty catches it and looks at Barney with a smile on her face and they kiss.
