Five years before MAD MAX, producer/director/co-writer/star Sandy Harbutt ignited Australia’s exploitation explosion, launched a global censorship battle, and delivered what may still be the best biker movie in history—STONE! When an undercover cop infiltrates an outlaw motorcycle gang (led by Harbutt), he’ll straddle 7000 RPM of screaming steel for a full-throttle ride through sex, violence, and Down Under vengeance. Hugh Keays-Byrne (Immortan Joe in MAD MAX: FURY ROAD), Helen Morse (PICNIC AT HANGING ROCK), and members of the Sydney Hells Angels co-star in this action-packed hellride, now featuring an uncut 4K scan from original vault elements supervised by Harbutt himself shortly before his death.
