The Man Called Flintstone(1966) starring the voice talents of Alan Reed, Mel Blanc, Harvey Korman

One of my favorite childhood movies was The Man Called Flintstone. Released after the end of the original TV series, it uses the well-worn plot line of Fred being an identical duplicate of some “important” person. In this case, secret agent Rock Slagg.  Slagg’s boss, Chief Mountmore, decides to use Fred to complete Slagg’s mission.  To capture of the evil criminal genius, the Green Goose (voiced with glee by Harvey Korman) …. Before he can take over the world.
