The Jetsons Meet the Flintstones is a 1987 animated crossover made-for-television film produced by Hanna-Barbera for syndication as part of the Hanna-Barbera Superstars 10 series. The two-hour special stars the cast of the Hanna-Barbera sitcoms The Flintstones and The Jetsons as they cross paths following a time travel experiment gone wrong.

In the future, while Elroy is busy working on a time machine, George Jetson comes to Mr. Spacely's office for a serious discussion. Spacely's rival, Cogswell, has been stealing Spacely's business ideas, putting their jobs in jeopardy. Spacely wrongfully blames George, suspecting that he was spying for Cogswell. Spacely orders George to spy on Cogswell to clear his name to avoid getting fired. George finds out that Cogswell's robot computer, S.A.R.A., has been seducing the Spacely robot computer, R.U.D.I., into leaking Mr. Spacely's secrets. George tries to report this to Spacely, but R.U.D.I. sabotages his efforts.
