Lady J (French: Mademoiselle de Joncquières) is a 2018 French period drama film directed by Emmanuel Mouret and inspired by a story in Denis Diderot's novel Jacques the Fatalist, which had already been adapted in 1945 for the film Les Dames du Bois de Boulogne by Robert Bresson. Set in France before 1789, it stars Cécile de France as Madame de La Pommeraye, an attractive widow whose bachelor lover, the Marquis des Arcis (Édouard Baer), will not propose to her and gets her revenge by tricking him into marrying Mademoiselle de Joncquières (Alice Isaaz), a former prostitute.
