An air of surreal dread permeates every frame of Monte Hellman’s experimental acid Western. Oates is an ex–bounty hunter who, with his faithful but none-too-bright partner (Will Hutchins), is recruited by a mystery woman (Millie Perkins) to lead her on an unexplained journey through the desert. Adrift in a sunbaked wasteland, the trio tramps onward toward god knows what—until they’re accosted by Jack Nicholson’s sinister, black-clad gunslinger. Financed by an uncredited Roger Corman, this cult-classic crypto-oater plays something like a Western crossed with Last Year at Marienbad—all leading up to a brain-bending final sequence.
