This tale of intrigue and corruption is based on a true account of 18th Century French noblewoman Jeanne de la Motte-Valois (played by Oscar-winner Hilary Swank), whose family has been dispossessed of status and title by the king. To restore honor to her name, not to mention reclaim her family estate, Jeanne must have her lineage officially authenticated at the court of Versailles. After several unsuccessful attempts to obtain an audience with Marie Antoinette (Joely Richardson), Jeanne finds an ally in male courtesan Rétaux de la Villette (Simon Baker), who advises her to try and gain influence at court by attracting a wealthy sponsor: Cardinal Rohan (Jonathan Pryce), a ruthless man whose appetite for women is only exceeded by his appetite for power. Aided by Villette, her estranged husband Nicolas (Adrien Brody), and an enigmatic foreign mystic, Count Cagliostro (Christopher Walken), Jeanne becomes embroiled in an elaborate scheme involving the cardinal, the queen, and the theft of a priceless diamond necklace. Director Charles Shyer's opulent costume drama, set against a backdrop of increasing civil unrest in pre-revolutionary France, was filmed in Prague and on location at Versailles.
