Just before or during the shooting, Jean Gabin, Michel Audiard and Gilles Grangier discussed about the climax scene so loudly, in summer, in the garden of Grangier's villa, that the nearest neighbors heard about the details of the scene and told it to everyone.
Jacques Deray, who was assistant director on the set, said that one day, during an outdoor shooting, one man approached director Gilles Grangier, without knowing who he was, and asked him what was the name of the director of the movie. Grangier told it was Gilles Grangier. The bystander then replied that this choice of directing was not the best at all.
The teacher, Alice (Jeanne Moreau) scolds a little boy for misbehaving, calling him Deray. Jacques Deray was the film's assistant director.
