 For the scene of Claire Lescot's concert L'Herbier hired the Théâtre des Champs-Élysées and invited over 2000 people from the film world and fashionable society to attend in evening dress and to play the part of an unruly audience.Ten cameras were deployed around the theatre to record their reactions to the concert.This included the American pianist George Antheil performing some of his own dissonant compositions which created a suitably confrontational mood, and when Georgette Leblanc appeared on stage the audience responded with the required tumult of whistles, applause and protests, as well as some scuffles.
