This movie is a loose adaptation of the 1934 play "Mon crime," by Georges Berr and Louis Verneuil, which has already been adapted twice by Hollywood: Cross My Heart (1946) and True Confession (1937).
Director François Ozon cast two young actresses for the leads, which both just got their breakthroughs the previous year: the role of Young Simone in Simone, le voyage du siècle (2022) for Rebecca Marder and the role of Stella in Les Amandiers (2022) for Nadia Tereszkiewicz.
Filming took place from April to June 2022, in Paris and its surroundings, as well as in Belgium, in the cities of Charleroi and Brussels.
The poster for the fictional play "Dans Le Calvaire de Suzette" copies a famous photo of film actress Louise Brooks (black and white, with an iconic string of pearls).
