Footage from Ganja & Hess.
After getting stabbed with an ancient sacrificial dagger by his new research assistant (Bill Gunn), erudite anthropologist Hess Green (Duane Jones) awakens to find that his wound has healed — but he’s acquired a voracious craving for blood. Charting Green’s growing conflict between his blood addiction and a hope for spiritual deliverance, this surreal tale — which has become a cult favorite — turns the vampire myth on its head.
