Le secret du Chevalier d'Éon

Le secret du Chevalier d'Éon is a 1959 French-Italian film. It stars Andrée Debar and Gabriele Ferzetti. It is loosely based on the life of Chevalier d'Éon, although it portrays them as a woman masquerading as a man, rather than a person who was biologically male but presenting as a woman, as was the case for the latter part of their life.
