Catherine Deneuve appears in French director Christophe Honoré's new film "Marcello Mio". Honoré is known for his provocative features; this is his third time in competition at Cannes. In this film, his longtime collaborator and Deneuve's real-life daughter Chiara Mastroianni plays a version of herself, who adopts the persona of her movie star father, Marcello Mastroianni, creating chaos with her mother.
