The film is a theatrical spin-off of the 1960-1966 television series, The Flintstones, and is considered the official swan song of the classic TV show as it was made immediately following the end of production on the series.
The Man Called Flintstone is a spoof of the James Bond films, and also borrows elements from several episodes of the Flintstone TV series.
In the film, Fred Flintstone (voiced by Alan Reed) is recruited by a secret organization to take the place of Rock Slag, an injured agent (voiced by Paul Frees) who happens to be Fred's doppelgänger. His mission: to travel to "Eurock" (under the guise of a family vacation) and catch the evil Green Goose (also voiced by Paul Frees). The catch is Fred is unable to tell his family or friends about the mission. Mel Blanc once again provides the voice of Fred's sidekick, Barney Rubble. The movie includes numerous musical interludes, including one song performed by Louis Prima. The singing voice of Fred is provided by Henry Corden, who would go on to fully assume the role of Fred after Reed's death in 1977.
The film borrows themes from several episodes of the TV series, including an episode in which Fred becomes involved in a spy caper spoofing Goldfinger, and another in which he encounters JL Gotrocks, the world's richest man, and his exact double.
The film was a minor success upon its original release, but in the succeeding years became more popular at cinema matinees, and on television. In 2005, a North American DVD version was released by Warner Home Video. However, owing to licensing complications between Warner Bros. (current owners of the Flintstones property) and Sony (current owners of then-Flintstones distributor Columbia Pictures/Screen Gems), only a Canadian release occurred; a United States release was canceled and would not be rescheduled until the rights issue was cleared in August 2008. The DVD will be released in the United States on December 2, 2008, along with a DVD of Hey There, It's Yogi Bear, a film with which The Man Called Flintstone was released as a double-bill during the 1970s.
