The movie will mark the directorial debut of Vanessa Filho, reported Variety.
"Gueule d'Ange" was written by Filho, in collaboration with Alain Dias, aka Diasteme, a writer-director whose 2015 thriller "French Blood" played at Toronto Film Festival.
The drama follows a single mother who abandons her eight-year-old daughter after meeting someone in a nightclub. Cotillard will star in the film opposite Ayline Etaix, Alban Lenoir and Amelie Daure.
The movie is being produced by Carole Lambert through her new company Windy Production and the well-established producer Marc Missonnier via his banner Moana Films. Stephane Celerier's Mars Films is co-producing and will distribute it in France.
