Gaspar Noé (who is bald in real life) wears a wig in this film. He told Lucile Hadzihalilovic that his only condition to appear in the film was wearing a wig, and he would do it for free.
For the first time director Gaspar Noé appears in a film directed by his wife Lucile Hadzihalilovic. She had previously produced several of Noé's films, as well as editing his first feature film and collaborating on the screenplay for Enter the Void (2009).
This is the second collaboration between director Lucile Hadzihalilovic and actress Marion Cotillard, after having worked on Hadzihalilovic's first feature film, Innocence (2004), released 21 years previously.
Filming began in January 2024 and wrapped in March 2024. It was filmed in Paris and Yvelines in France, and in the city of Bolzano in Northern Italy.
