The Flintstones in Viva Rock Vegas (2000)

Fred Flintstone and his best friend Barney Rubble are on top of the world. They have just graduated from the Bronto Crane Academy and secured jobs at the rock quarry in Bedrock, and life couldn't be better. Wilma Slaghoople, the beautiful young heiress and daughter to Colonel and Pearl Slaghoople, is miserable. Her mother, resplendent in the latest Isaac Mizraki gown as she dines on caveiar, has Wilma's life mapped out for her, including a marriage to the suave and debonair Chip Rockefeller. He does drive a Cadirock and he was first in his class at Princestone, but to Wilma he's a total bore, so she runs away from home. In Bedrock, Wilma meets Betty O'Shale, and the two become fast friends, residing at Melrock Place and working at the local Bronto King. Following a disastrous first date, Fred ends up falling head over heels in love with Wilma, while Barney and Betty become inseparable. So, leaving puppy Dino behind, Fred and Barney- along with a green alien from outer space, The Great Gazoo-whisk the girls away on a BC-10 for a romantic weekend in Rock Vegas. But Chip has other plans in mind, and with the help of Roxie, a Rock Vegas showgirl, Rockefeller devises a plan to get Fred out of the picture once and for all, leaving Wilma and her family's fortune all to himself.
