Jeanne Moreau as Catherine in Jules & Jim (1962, dir. Francois Truffaut)

Although the film is named for the men, its animating force is Catherine, a creature both utterly timeless (Jules and Jim first see her visage in a photo of a Greek statue) and forever changing: at different points, she plays the roles of Charlie Chaplin and street tough, vamp, and doting mother. Passionate and iconoclastic, she is, in fact, the only true free spirit among them. Just as the men put their talent into their art, so she puts her genius into living—or perhaps into claiming for herself the reckless male freedoms that women have been traditionally denied.

On paper, the mercurial Catherine seems an implausibly grandiose conception, a woman both giddy and tragic, protofeminist and male-dominated, driven by Eros and Thanatos, love and death. But as played by Jeanne Moreau, a pop-eyed siren with the ferocity of Bette Davis and the kitty-cat wiles of Tuesday Weld, Catherine becomes one of the modern movies’ triumphant characterizations—the anima as autocrat. Whether playing with vitriol or jumping into the Seine, she elevates capriciousness to an existential principle. When Jim says he understands her, she replies, “I don’t want to be understood.” And this is absolutely true.
