At Work: Sylvie Guillem joined the corps de ballet of the Paris Opera when she was just 15 and earned the distinction of Prima Ballerina within a mere 4 years. At the age of 19, she became an etoile in Nureyev's Swan Lake. This film shows the prima ballerina in her daily round of classes, rehearsals, and performances, revealing her dedication to perfection. Portrait: Sylvie Guillem's breathtaking technique ranks her beside the likes of Nureyev and Baryshnikov. She rarely agrees to interviews. This profile with director Nigel Wattis is both rare and enlightening.
