Mauvaise Graine (Bad Seed) is a 1934 French drama film directed by Billy Wilder (credited as Billie Wilder) and Alexander Esway. The screenplay by Wilder, H.G. Lustig, Max Kolpé, and Claude-André Puget focuses on a wealthy young playboy who becomes involved with a gang of car thieves. Although Wilder and Esway shared the directing credit, in later years leading lady Danielle Darrieux recalled Esway was involved with the project in some capacity but clearly remembered she never saw him on the set. In her opinion the film, which marked Wilder's directorial debut, was his alone.
