Lady Blue Shanghai is a 16-minute internet promotion motion picture for Dior starring Marion Cotillard, Gong Tao, Emily Stofle, Cheng Hong, Lu Yong and Nie Fei. It was written, directed and edited by David Lynch, with music by David Lynch, Dean Hurley, and Nathaniel Shilkret. There are prominent dreamlike effects and special attention to background music, as is common in Lynch films. The film centers on the circumstances leading to Cotillard hearing 1920s music and seeing the mysterious appearance, with special effects using smoke, of a Dior handbag as she enters her hotel room in Shanghai.
