If nothing else, Hollywood's wartime "Good Neighbor" policy towards South America brought Carmen Miranda to the forefront. Back in the 1940s, Carmen had 'em rolling in the aisles with her butchering of the English language and her rococo millinery that imitated exotic fruit baskets. Today, she is mostly High Camp but as such can become quite infectious. Springtime in the Rockies, meanwhile, is less a refreshing tour of the great outdoors as it is a Mack Gordon-Harry Warren songbook. In fact, the scenery is all rear projection and no one ever actually leaves the confines of a 20th Century-Fox soundstage. But with such garrulous entertainers as Miss Miranda, Betty Grable, Charlotte Greenwood (who, as always, is all legs and tart asides), Banda Da Lua and a jiving group of juvenile delinquents known as Six Hits and a Miss, no one should mind the rather humid conditions. Add to all that the genial Harry James, who performs such numbers as his own and Count Basie's "Two O'Clock Jump" and "Run, Little Raindrop, Run", and a good time is had by all.
