The 1967 film “Les demoiselles de Rochefort” by Jacques Demy starred a young Catherine Deneuve and her real-life sister Françoise Dorleac as twins living in the French seaside town of Rochefort, where they sang and danced their way through a series of pastel settings in search of true love. Almost 60 years later, the movie has come to life in a show at the Lido theatre on the Champs-Élysées in Paris. We speak to Juliette Tacchino and Marine Chagnon, the two French actresses who play the twins Delphine and Solange.
