Anastasia (1956 movie)
The Russians, led by General Bounine (played by Yul Brynner), teach her how to behave as the Grand Duchess Anastasia would.  They teach her everything she ought to know about her childhood.  They teach her to walk like a Duchess, practicing with a book on her head.  When they think she is ready, she is introduced to several people who knew Anastasia.  None of them believe she really is Anastasia.  The real test comes when she is taken by General Bounine (Brynner) to Denmark to meet the Dowager Empress, Maria Feodorovna, mother of the Tsar, played by Helen Hayes.  At first the old Empress does not believe the young woman is her granddaughter, but when Anastasia coughs because she is nervous, the Empress remembers that Anastasia used to do this as a child.  She now believes she is her granddaughter. Meanwhile, Prince Paul wants to marry Anastasia.  He's obviously after the money he thinks she will inherit.   In the final scene, there is a party.  The Dowager Empress is going to announce the engagement between Paul and Anastasia, but Anastasia and General Bounine have suddenly disappeared.  The Dowager realizes that Anastasia does not desire fame, but simply love, with the man of her choosing.  She says very bravely that she will go in to where all the guests are waiting and tell them that the party is over and that they should go home.
