In 1968, Park was cast as Clara in Rudolf Nureyev's production of "The Nutcracker", dancing with him in the lyrical duet in act 1 and in the spectacular pas de deux that is the climax of act 2. It proved to be the role that made her a star. A brilliant technician, an accomplished actress, and a glamorous personality on stage, she was also greatly admired as Giselle, as Cinderella, and, particularly, as Aurora in "The Sleeping Beauty". She gave more performances of "Giselle" than any other artiste in the history of the company. In 1973, she danced the dual role of Odette/Odile in "Swan Lake" for the first of many acclaimed performances. In the ballets of Frederick Ashton, she shone as Lise in "La Fille mal gardée" and as Titania in "The Dream". Ashton's "Symphonic Variations", a plotless work set to the score by César Franck, provided her opportunity to display her musicality and classical precision, as did the role of the Indian temple dancer Nikiya in "La Bayadère". In contrast, her impersonation of Kate in Cranko's wildly funny "The Taming of the Shrew", set to music by Domenico Scarlatti, sparkled with roguish humor. She also gave highly dramatic performances in the title roles of Kenneth MacMillan's "Romeo and Juliet" and "Manon", set to scores by Serge Prokofiev and Jules Massenet, respectively. Photographs of her in these roles reveal a talented dance actress at work.
