In 1985, producers Keith Barish and Joel Silver bought the rights for a live-action feature film version of The Flintstones and commissioned Steven E. de Souza to write a script with Richard Donner hired to direct. De Souza's script was eventually rejected and Mitch Markowitz was hired to write a script. Said to be a cross of The Grapes of Wrath, Markowitz commented that "I don't even remember it that well, but Fred and Barney leave their town during a terrible depression and go across the country, or whatever that damn prehistoric thing is, looking for jobs. They wind up in trailer parks trying to keep their families together. They exhibit moments of heroism and poignancy". Markowitz's version was apparently too sentimental for Director Donner, who disliked it. Eventually, the rights were bought by Amblin Entertainment and Steven Spielberg who, after working with Goodman on Always, was determined to cast him in the lead as Fred. Brian Levant was hired as Director, knowing he was the right person because of his love for the original series. They knew he was an avid fan of the series because of his Flintstones items collection and the knowledge he had from the series.

The film was released, first on VHS and LaserDisc on November 8, 1994 by MCA/Universal Home Video. It later made its debut on DVD on September 24, 1999 and finally to Blu-ray on August 19, 2014.

McDonald's marketed a number of Flintstones promotions for the film, including the return of the McRib sandwich and the "Grand Poobah Meal" combo with it, a line of premium glass mugs, and toys based on characters and locations from the film. In the commercials and released items for the Flintstones promotion, McDonald's was renamed "RocDonald's" with stone age imagery, similarly to other businesses and proper names in the Flintstones franchise. A video game based on the film was developed by Ocean software and released for the Super Nintendo Entertainment System, Game Boy and Mega Drive/Genesis (Sega Channel exclusive) in 1995. In the United Kingdom, Tetley promoted adverts with audio from the film, including mugs starring characters from the film. Jurassic Park, the name of another movie was also seen briefly as a park in the film.

The film review aggregator website Rotten Tomatoes gave the film a 23% "Rotten" rating based on 44 reviews with an average rating of 3.7/10. At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream critics, the film has received an average score of 38 out of 100, which indicates "generally unfavorable reviews", based on 15 reviews. On Siskel and Ebert, Gene Siskel of the Chicago Tribune and Roger Ebert of the Chicago Sun-Times gave the film two marginal thumbs down. They both mentioned that its main story lines (embezzlement, mother-in-law problems, office politics and extra-marital affairs) were storylines for adult films, and ones that children would not be able to understand. However, many critics praised the film's look, faithfulness to the cartoon, Rosanna Norton's costume designs and Goodman's performance. A few reviews were positive, including Time magazine which said "The Flintstones is fun", and Joel Siegel from ABC's Good Morning America and WABC-TV who called the film "pre-historical, hysterical... great fun". In a 1997 interview, Joseph Barbera, co-creator of The Flintstones and co-founder of Hanna-Barbera Productions, stated that, although he was impressed by the film's visuals, he felt the story "wasn't as good as I could have made it."

A prequel, The Flintstones in Viva Rock Vegas, was released in 2000. The original main cast did not reprise their roles of the characters, though O'Donnell provided the voice of an octopus who gave massages to younger versions of Wilma and Betty. Irwin Keyes returned as Joe Rockhead, the only cast member to reprise his role from the first film. Unlike its predecessor, it disappointed at the box office.
