"Movies are about movement," says documentary filmmaker Frederick Wiseman, and in his newest film, La Danse: The Paris Opera Ballet, he examines the movement of ballet. The film gets inside the workings of the ballet, from rehearsals to marketing sessions, and follows the company through the production of seven ballets: Genus by Wayne McGregor, Le Songe de Medée by Angelin Preljocaj, La Maison de Bernarda by Mats Ek, Paquita by Pierre Lacotte, Casse Noisette by Rudolph Noureev, Orphée and Eurydice by Pina Bausch, and Romeo and Juliette by Sasha Waltz.
