Akira Kurosawa’s adaptation of an American detective novel is both a superb, suspenseful thriller, and a Dostoyevskian metaphysical probe into the ambiguities of guilt and innocence. In one of his finest performances, Toshiro Mifune portrays a wealthy executive who must pay ransom for the release of his chauffeur’s son when the boy is mistaken for his son by a kidnapper. Kurosawa creates a constant, often ironic interplay between high and low, heaven and hell, presenting the case from the perspective of the wealthy man’s hilltop home, then from the kidnapper’s realm below, where the action descends for a manhunt that is a dazzling piece of filmmaking.
