Ernst Lubitsch described this film as "caviar"; critics have called it the best comedy of the late forties, and it is probably Sturges' most sophisticated and complex creation. Smoothly switching from fantasy to reality, from slapstick to black comedy, Sturges weaves a cynical story of adultery and deception. Rex Harrison is ideally cast as a brilliant conductor who suspects his beautiful wife (Linda Darnell) of adultery, based on the reports of his insipid brother-in-law (Rudy Vallee). As he conducts Rossini, Wagner or Tchaikovsky, in his mind he hatches one hilarious murder plot after the other, each inspired by the musical score and all in keeping with his thoroughly sophisticated lifestyle. Sturges achieves a rare balance between music, dialogue and visuals, each complementing the other and adding to the wit of this memorable classic.
