Sir Kenneth MacMillan's ballet "Anastasia", first performed in 1967, used "I, Anastasia, an autobiography" as inspiration and "is a dramatic fantasy about Anna Anderson, the woman who believes herself to be Anastasia ... Either in memory or imagination, she experiences episodes from Anastasia's past ... The structure is a kind of free-wheeling nightmare, held together by the central figure of the heroine, played by Lynn Seymour". A contemporary reviewer thought Seymour's "tense, tormented portrait of the desperate Anna Anderson is quite extraordinary and really impressive". Anna Anderson was also used as a narrative device in Youri Vámos' 1992 ballet for Theater Basel, "Sleeping Beauty – Last Daughter of the Czar", based on Pyotr Ilyich Tchaikovsky's "Sleeping Beauty".
