Bergman is charming as an amnesiac young woman who is recruited by Brynner to impersonate the daughter of the late czar. Bergman won her second Oscar for her portrayal. Brynner is good as the exiled Russian who tries to bring her back into a world she once may have known and Hayes is stand out as the grand dutchess who strives to find the truth behind this girls' credentials. Crisp direction from Anatole Litvak and a lively supporting cast of Akim Tamiroff make this a simply ravishing film.
