Denis Lavant, Carax’s onscreen alter ego, and Juliette Binoche are young vagrants who meet on Paris’s famed Pont Neuf. Alex is a fire-eating street performer and addict. Michèle is a heartbroken painter who is slowly going blind. Carax’s dazzling, delirious chronicle of their “amour fou” is a vivid, visionary, pyrotechnic valentine to Paris—much of it shot on a life-size replica of the Pont Neuf and its environs, built at budget-busting expense in southern France.
