Nelson Eddy and Jeanette MacDonald together again in Paris, where they have to fight her evil husband, John Barrymore, for the right to croon “Mammy’s Little Baby Loves Shortenin’ Bread” and Tchaikovsky’s Fifth Symphony. The MacDonald-Eddy combination was a box-office behemoth during the Depression (Maytime was the biggest grossing film of 1937), with Shirley Temple as its only rival in schmaltz appeal. But the secret of their success, one might say, has been clouded by the mists of time—this one’s strictly for buffs and cinema sociologists. Robert Z. Leonard directed.
