The Mississippi River's never seen as many wild twists as in this spirited and extravagant riverboat ride which stars the King of Rock 'n' Roll Elvis Presley (Clambake) with the lovely Donna Douglas (TV’s The Beverly Hillbillies) and featuring hilarious support from Harry Morgan (Support Your Local Sheriff) and eleven original Presley tunes, Frankie and Johnny is a sure-fire romp with pretty girls, toe-tapping score and Elvis all the way. Presley is Johnny, a riverboat singer whose life, according to girlfriend and singing partner Frankie (Douglas), has become "one great big roulette wheel." And he's so obsessed with that wheel of misfortune that when a gypsy woman prescribes a redhead to be his good luck charm, Johnny sets out to find one. Trouble is, Frankie is most definitely a blonde... and a jealous blonde at that. When she sees Johnny with curvaceous carrot-top Nellie Bly (Nancy Kovack, Jason and the Argonauts), Frankie decides that she'll break off her romance with Johnny. The wonderful supporting cast includes Sue Ane Langdon (The Rounders) and Robert Strauss (Stalag 17).
