Exercise togs worn by members (male & female) of the villain\\\'s \\\"perfect race\\\" will performing calisthenics in the garden of his estate (atually Vaux-le-Vicomte outside Paris).
Mostly white Lycra.
I\\\'m always intrigued by the \\\"magic\\\" of movies and in discussing the sequence with cast members some noted they were never there; indeed most of the actors used for this scene are not those shot in close-up throughout the rest of the film.
