Doris Day and Howard Keel fuss, feud and fall in love as Calamity Jane and Wild Bill Hickok in this entertainment mother lode. At first curvaceous Calamity is too durned busy fighting Indians and cracking a bullwhip to pay mind to such girlie what-alls as dresses and perfume. And Wild Bill is too danged busy wooing a dainty chateuse (Allyn McLerie) to give a hoot about a hot-headed tomboy. But things change in a rootin, tootin, big way when each becomes loves target. There are wide-open Technicolor Western spaces, lots of high-stepping dances and a hummable humdinger of a score by Academy Award- winning* songwriters Sammy Fain and Paul Francis Webster, who took their first Oscar for the classic ballad (and 50s megahit) Secret Love.
