In 1960, when shooting his first movie in Paris, as a car was in the way, Lelouch wanted to ask the driver to move it a few meters further. The only person in the car was Edith Piaf, in the backseat, waiting for her driver. As he was a great admirer of both Marcel Cerdan and Edith Piaf, she took a few minutes to tell him how she and Marcel Cerdan met. Edith Piaf then told Lelouch that if he was a movie director, that story would be a gift from her. And he shot Edith and Marcel.
