A tour de force of psychic dread that begins as an ambient murmur and builds to an existential shriek, legendary Polish director Jerzy Skolimowski’s provocative adaptation of a short story by Robert Graves is a hallucinatory confrontation with the unknown. In a small English village, an experimental composer (John Hurt) and his wife (Susannah York) see their routine existence upended by the arrival of an enigmatic stranger (a seductively sinister Alan Bates), who claims to possess knowledge of Aboriginal magic and the ability to kill using a deadly scream—a power that makes him an object of both terror and desire. With its puzzle-box structure, unnerving ambiguity, and otherworldly electronic sound design, this Cannes Film Festival award winner quivers with the primal fear of mysterious and uncontrollable forces.
