Cornpone comedienne Judy Canova tackles a science-fiction theme in Carolina Cannonball, her last starring vehicle for Republic Pictures. This time, Canova and her grandpa Andy Clyde comprise the entire population of the ghost town of Roaring Gulch. They put food on the table by operating the Carolina Cannonball, a trolley service to the nearest city. Early one morning, an atomic-powered missile crashes just outside of Judy's house. She appropriates the missile's engine and attaches it to the Cannonball, considerably improving the trolley's speed capacity. Before long the pair are up to their necks in federal agents and enemy spies. Before the obligatory slapstick-chase finale, Judy Canova is permitted to sing a song or two. ~ Hal Erickson, Rovi
