Unfaithfully Yours is Sturges's most complex and fascinating creation: a unique hybrid of character satire, symphony, and slapstick, with a strong undercurrent of noir desperation. Rex Harrison is frighteningly funny as Sir Alfred de Carter, a British conductor who believes in the elevating, morally "antiseptic" qualities of music and deplores American vulgarity in all its forms, including the movies. His aristocratic self-satisfaction is shaken when, thanks to the interference of an insufferable brother-in-law (Rudy Vallee), he begins to doubt the faithfulness of his wife (Linda Darnell). While he conducts Rossini, Wagner, and Tchaikovsky, Sir Alfred concocts vivid fantasies of revenge and sacrifice, each in keeping with the mood of the music and all highlighting our hero's genius, sophistication, and dignity. But in real life, dignity is hard to come by, as Sturges demonstrates in some of the most effective scenes of physical comedy he ever directed.
