Filmed back to back with its sequel, Die drei Musketiere - Milady (2023), and took only 150 days to shoot after starting August 16, 2021, and wrapping on June 3, 2022.
François Civil performed 90% of his own stunts in both films after completing an intense, six-month training regimen for preparation on fencing, sword-fighting and horseback riding.
Almost entirely shot on location in France. Out of the 150 days spent shooting this film, and its sequel Die drei Musketiere - Milady (2023), only one day was scheduled for filming in the studio.
Producer Dimitri Rassam said he and director Martin Bourboulon watched several films for inspiration during preparation, including Cyrano von Bergerac (1990), Die Bartholomäusnacht (1994), Die Duellisten (1977) and Jäger des verlorenen Schatzes (1981).
Olympic Épée Champion Yannick Borel was the fencing trainer for François Civil, Vincent Cassel, Romain Duris and Pio Marmaï.
