The film was a co-production between Les Films du Lendemain and the director's company My New Picture, in collaboration with Arte France Cinéma. The production received 540,000 euro from the Centre national du cinéma et de l'image animée (CNC) and 416,000 euro from the Île-de-France region, as well as pre-sales investment from Canal+ and CinéCinéma. The total budget was 3.8 million euro. Casting took almost nine months. Bonello wanted a mixed ensemble of both professionals and amateurs who above all worked well together as a group.
