Plot Marie Antoinette (Dunst), a 14 year-old Austrian princess, is sent to marry the future king of France, Louis XVI (Schwartzman). Ascending to the throne aged 19 and under constant pressure to produce an heir, Marie tries to escape her stultifying existence.Verdict If not particularly useful as a GCSE study guide or a deep psychological portrait, Marie Antoinette is gorgeous, giddy, gilded filmmaking.
