Dubbed “a cyberpunk Eraserhead” in Michael J. Weldon’s 1983 book The Psychotronic Video Guide, this defining Japanese cyberpunk film melds Cronenbergian body horror and Lynchian surrealism for a manic, man-versus-machine Tilt-a-Whirl. In a tech-age update to Franz Kafka’s “The Metamorphosis,” an office worker wakes up to find he’s becoming a machine, a reality that sends him on a tear of ultraviolence. Unavailable theatrically for over thirty years, this new digital restoration showcases the no-holds-barred cinematography of filmmaker Shinya Tsukamoto and star Kei Fujiwara; it’s an in-your-face excess of underground ethics and DIY spirit.
