Tetsuo: The Iron Man is a 1989 Japanese cyberpunk film by cult-film director Shinya Tsukamoto produced by Japan Home Video.
This, his third film, is an extremely graphic but also strikingly-filmed fantasy shot in the same low-budget, underground-production style as his first two films.
Tetsuo established Tsukamoto internationally and created his worldwide cult following. It was followed by Tetsuo II: Body Hammer (1992) and Tetsuo: The Bullet Man (2009).
