The 1941 musical comedy with songs by Cole Porter helped propel Rita Hayworth from B pictures to major stardom and shows her to be as able a partner for Fred Astaire as Ginger Rogers (her real-life cousin). A Broadway hoofer (Astaire) enters the army, hoping to escape a messy charade involving his married boss (Robert Benchley) and a radiant chorus girl (Hayworth). The leads’ chemistry lifts them over the clunky screwball plot, and Robert Alton’s choreography soars too, from a Latin-flavored number echoing Hayworth’s early days as a Tijuana cantina attraction to the rat-a-tat-tat of the precision tap dances reflecting a nation as it gears up for war. Sidney Lanfield (My Favorite Blonde) directed. 88 min.
