The film explores the effects of a luxurious yet terribly confining lifestyle on the young queen and ultimately led to her undoing.
Fourteen-year-old Maria Antonia (Kirsten Dunst) is the beautiful, charming, and naive Archduchess of Austria, youngest of Empress Maria Theresa's (Marianne Faithfull) daughters. In 1770, the only one left unmarried among her sisters, she is sent by her mother to marry the Dauphin of France, the future Louis XVI of France (Jason Schwartzman), to seal an alliance between the two rival countries. Marie Antoinette travels to France, relinquishing all connections with her home country, including her pet Pug "Mops", and meets the King Louis XV of France (Rip Torn) and her future husband, Louis Auguste. The two arrive at the Palace of Versailles, which was built by the King's great-grandfather. They are married at once and are encouraged to produce an heir to the throne as soon as possible, but the next day it is reported to the king that "nothing happened" on the wedding night... --Wikipedia
Given Coppola's fashion-first approach, it's a miracle the film doesn't feel more like a long perfume ad. But the movie has atmosphere, beauty, spirit, and exquisite production design, photography, and editing.
