Overview
Sweethearts is a 1938 American Technicolor musical romance film directed by W.S. Van Dyke and starring Jeanette MacDonald and Nelson Eddy. The screenplay, by Dorothy Parker and Alan Campbell, uses the “play within a play” device: a Broadway production of the 1913 Victor Herbert operetta is the setting for another pair of sweethearts, the stars of the show. It was the first color film for Nelson or Jeanette (as well as MGM's first three strip Technicolor feature). It was their first film together without uniforms or period costumes.
Plot
Broadway stars Gwen Marlowe (Jeanette MacDonald) and Ernest Lane (Nelson Eddy) are appearing in a 6-year run of Victor Herbert's operetta Sweethearts (Ray Bolger dances the role of Hans). They are also very much in love after six years of marriage. Norman Trumpett (Reginald Gardiner) is a successful Hollywood talent scout under pressure to recruit Marlowe and Lane for his studio, which their Broadway producer Felix Lehman (Frank Morgan) is equally determined to prevent.
The couple's attempts to rest and be together are repeatedly thwarted by professional and personal demands made on their time, talents and money by Lehman and their own theatrical families - who also live with them. Frustrated beyond endurance and seduced by Trumpett's idyllic (and false) description of working conditions in Hollywood, they decide to quit the show and take the Hollywood offer. (In guise of buying a new wardrobe for the trip Jeanette MacDonald models fashions of 1938.)
