La Nuit and would begin filming in October 2025, with
Antoine Reinartz and
Grégory Gadebois starring. In a December 2025 interview, Auteuil commented: "It's a story that deeply moved me. When it was proposed to me, I felt the urge to immerse myself in it and tell it. Human suffering is still, unfortunately, relevant." In September 2025, a casting call was held in
Le Mans for children to portray Jewish children held prisoner in a camp. In October 2025, a second casting call was held in Le Mans seeking one hundred extras aged 18 to 65 to portray police officers, gendarmes, doctors, nurses, nuns, prisoners, patients, bus drivers and more.
