Welles, challenged to try a ballet at a chance meeting with Choreographer Roland Petit in Paris, tossed off a scenario idea on the spot: a young girl is frozen in a block of ice; thawed out by a young man's ardent dancing, she comes to life, but as her enthusiasm waxes, his wears out, and at the end it is he who is frozen solid. Welles helped with the staging, came through with a method of displaying Heroine Colette Marchand as if she were suspended in ice. Near the finish, he was dithering nervously in the wings when a drapery covering the frozen hero began to tear as it was raised. Stagehands began to panic, but Welles rose to the occasion: "Continuez! Continuez!" he yelled. "Let it tear! C'est magnifique!" The audience gave Welles an ovation.
