Not a remake of the 1934 Helen Morgan vehicle of the same title, Frankie and Johnny stars Elvis Presley as Johnny, a Mississippi gambler, and Beverly Hillbillies regular Donna Douglas as his girl friend Frankie. In keeping with the old ballad, the romance of Frankie and Johnny is threatened by the intervention of seductress Nellie Bly (Nancy Kovack). Nellie brings Johnny luck at the gaming tables while Frankie sees red. Frankie and Johnny was written by onetime Marx Brothers contributor Nat Perrin and directed by future Tonight Show helmsman Fred de Cordova.
