Anastasia is a 1956 film which tells the story of a young, confused woman in France after the Russian Revolution of 1917 who, backed by the Russian emigre community, attempts to pass herself off as Grand Duchess Anastasia Nikolaevna of Russia, the daughter of the murdered Tsar Nicholas II of Russia. It stars Ingrid Bergman as the possible Grand Duchess, Yul Brynner as a dashing ex-aristocrat, and Helen Hayes as the Dowager Empress Maria Fyodorovna. Supporting players include Akim Tamiroff, Martita Hunt (who provides comic relief as a fluttering lady-in-waiting), and, in a small role, Natalie Schafer (familiar to television audiences from her later role on Gilligan's Island).
