The movie is dedicated to Terry Jones, former Monty Python member who died in January 2020, who had played in two of Albert Dupontel's movies: Le créateur (1999) (as God) and Enfermés dehors (2006) (as a homeless person). Incidentally, another former Monty Python member plays in the present movie: Terry Gilliam (as a hunter in the advertisement). Albert Dupontel has said that the Pythons are a source of inspiration for his work.
Guillaume Berroyer, son of Jackie Berroyer, plays the younger version of his father's character.
