Maurice Chevalier’s randy Viennese lieutenant is enamored of Claudette Colbert’s freethinking, all-girl-orchestra-leading cutie. Yet complications ensue when the sexually repressed princess (newcomer Miriam Hopkins) of the fictional kingdom of Flausenthurm sets her sights on him. Ernst Lubitsch’s The Smiling Lieutenant is a delightful showcase for its rising female stars, who are never more charming than when Colbert tunefully instructs Hopkins, “Jazz Up Your Lingerie.”
