Dreaming Lips was lovingly assembled by filmmaker Paul Czinner as an "ideal" vehicle for his popular actress wife Elizabeth Bergner. The star plays Gabrielle, the glamorous, spoiled wife of world-famous orchestra leader Peter (Romney Brent). Left alone by her constantly touring husband, she inaugurates a romance with brilliant but reclusive violinist Miguel de Vaye (Raymond Massey).
