Forbidden passion blazes between a brother and sister in this sexually delirious, rock 'n' roll romance. Working from a script originally written for François Truffaut, boundary-pushing director Valérie Donzelli spins a deliciously dark adult fairy tale in which the relationship between aristocratic siblings Marguerite (Anais Demoustier) and Julien (Jeremie Elkaim) goes from playfully flirtatious to passionately erotic—an affair that tests the limits of what society will accept. A provocative fable about what we’re willing to risk for love, Marguerite & Julien is a one-of-a-kind romance that transcends time, reason, and moral boundaries.
