Nelson Eddy and Rise Stevens star in an amusing film about a jealous husband, and his suspicions of his wife's infidelity. Nelson plays a dual role as the insecure husband and the Russian singer he impersonates to test his wife's loyalty. Rise is delicious as the teasing wife who exploits his doubts unmercifully. Nelson plays the Russian in a broad and sardonic manner which seems to prove again that he is more at ease and sure of himself in films without his usual costar and RL love interest. Nelson and Rise are in excellent voice. A couple of dances without the two leads could easily be cut. Neither approaches the humor of Nelson, nervously biting his nails, as he contemplates his insecurities.
