Variety Lights (Italian: Luci del varietà) is a 1950 Italian romantic drama film produced and directed by Federico Fellini and Alberto Lattuada and starring Peppino De Filippo, Carla Del Poggio, and Giulietta Masina. The film is about a beautiful and ambitious young woman who joins a traveling troupe of third-rate vaudevillians and inadvertently causes jealousy and emotional crises. A collaboration with Alberto Lattuada in production, direction, and writing, Variety Lights launched Fellini's directorial career. Prior to this film, Fellini worked primarily as a screenwriter, most notably working on Roberto Rossellini’s Rome, Open City.
