After finishing what would become his international phenomenon Rashomon, Akira Kurosawa immediately turned to one of the most daring, and problem-plagued, productions of his career. The Idiot, an adaptation of Fyodor Dostoyevsky’s nineteenth-century masterpiece about a wayward, pure soul’s reintegration into society—updated by Kurosawa to capture Japan’s postwar aimlessness—was a victim of studio interference and, finally, public indifference. Today, this “folly” looks ever more fascinating, a stylish, otherworldly evocation of one man’s wintry mindscape.
