The time-worn stage chestnut is a "play-within-a-film" for this frothy Jeanette MacDonald/Nelson Eddy musical comedy, written by Dorothy Parker and Alan Campbell. MacDonald and Eddy play Gwen Marlowe and Ernest Lane, a married acting couple who plan to leave Broadway for Hollywood, but impresario Felix Lehman (Frank Morgan) plots to stop them. With Ray Bolger, Florence Rice, Mischa Auer. 114 min. Standard; Soundtrack: English Dolby Digital mono; two "Screen Guild Players" radio broadcasts of "Sweethearts" with MacDonald and Eddy; pre-recording sessions, with outtakes and rare stereophonic mixes; theatrical trailer.
