Sophie Marceau trained with swords for 2 months prior to filming. She also did 90% of all her own stunts.
This was to be the first film to be directed in 14 years by Riccardo Freda. Freda, then 84, was fired from the project and his credit was removed. It was his last directing assignment.
The film takes place in 1654.
Sophie Marceau was publicly unhappy with the film's latter focus on the musketeers, arguing that the film should have concentrated wholly on her character, as the title suggests.
Sophie Marceau threatened Bertrand Tavernier to quit the shooting unless he gets rid of Ricardo Freda; whom Marceau disagreed with all the time. Freda refused to talk to her.
