What was the title of the 1987 TV crossover film between The Jetsons and the Flintstones?

The 1987 TV crossover film between The Jetsons and the Flintstones was titled The Jetsons Meet the Flintstones.

Produced by Hanna-Barbera, the film was made for television and released through syndication as part of the Hanna-Barbera Superstars 10 series. Its story begins with a time-travel experiment that brings George Jetson and his family into contact with Fred Flintstone and the residents of Bedrock.

The title can be confused with “The Flintstones Meet the Jetsons,” but that wording reverses the official order. The film is also sometimes treated like a theatrical feature because it runs about 92 minutes, yet it was a syndicated television film rather than a cinema release.

The crossover aired on November 15, 1987, and featured many original voice performers, including George O’Hanlon as George Jetson, Henry Corden as Fred Flintstone, and Mel Blanc in several roles. It remains one of the best-known meetings between Hanna-Barbera’s futuristic and prehistoric sitcom families.
