Jeanne Goupil made the paintings used in the film.
Joël Séria had traveled to Quebec to recruit the actress Dolores McDonough, whom he found sublime. She was to appear naked in a scene. On the day of the shoot, not having seen her in her simplest form yet, he asked his wife, Jeanne Goupil, who was also an actress in the film, to check her shape, especially her backside. The buttocks must be absolutely perfect. Jeanne Goupil complies and confirms: "It's OK, there's no problem, you can shoot."
