The crew was given permission to shoot in the Élysée palace, in the entrance court and one of the salons. Even though Emmanuel Macron, the President of the French Republic at the time, appears in the opening sequence, it's only through the use of archive footage and clever editing.
The film takes its working title from the collection of writings "Par Ce Demi-clair Matin" by Charles Peguy, a favorite of writer/director Bruno Dumont, who drew inspiration from it for this film.
Was initially slated for a 2020 release, but was pushed back due to the COVID-19 pandemic.
