It can exhaust us, and its characters are thin, but the handmade effects make the discomfort worth seeking out. ## Synopsis A Salaryman (Tomorowo Taguchi) starts to grow metal, with industrial machinery sprouting from his body. Alongside him are the Girlfriend (Kei Fujiwara) and the Metal Fetishist (Shinya Tsukamoto), a man whose preoccupation is metal itself. The Salaryman struggles to retain control as his body becomes increasingly mechanical. Sex and violence accompany the changes, and there is little dialogue to explain what is happening to him. His immediate problem is physical: the machinery is becoming part of him, with no clear boundary between the man and what is taking him over. ## Review *Tetsuo: The Iron Man* is abrasive, inventive horror, and we recommend it to anyone prepared for an evening with little breathing space. Shinya Tsukamoto takes the business of a man becoming a machine with a seriousness that makes the film’s nasty humour more effective. The metal keeps growing, and the man has scarcely a moment to get used to it. At 67 minutes, it has enough sense to finish before its constant assault becomes merely tiring, though it comes close. Tomorowo Taguchi plays the Salaryman as someone whose body has become impossible to manage. His contortions suggest real pain even when their exaggeration becomes funny. We were horrified by the machinery sprouting from his flesh. The handmade prosthetics make the transformation look painfully attached to a person, and the stop-motion movement denies us the comfort of a body behaving naturally. The visible awkwardness of the effects helps: smoothness would make this easier to dismiss. The photography, shared by Shinya Tsukamoto and Kei Fujiwara, uses harsh black and white to make the changes difficult to inspect comfortably. Flesh and metal begin to look horribly compatible. Those handmade surfaces matter as much as the speed: we can see enough of the physical construction to imagine its weight against skin. Keeping the effects so plainly physical gives the film a particular nastiness. There is little opportunity to admire a clever trick without also imagining how much it would hurt. Chu Ishikawa’s music supplies an industrial pulse that keeps the transformation from becoming a succession of gruesome exhibits. The beat is insistent enough to become uncomfortable before we have time to inspect the latest growth. Shinya Tsukamoto also edits, cutting with a speed that refuses a comfortable distance from the bodies. Stop-motion can be playful; here its broken movement makes even a pause feel unreliable. The pressure rarely eases. The writing is less satisfying when we ask who these people are beyond what their bodies want or suffer. Kei Fujiwara’s Girlfriend and Shinya Tsukamoto’s Metal Fetishist make that limitation plain: even their names leave little room for lives outside the nightmare. That suits a film so concerned with sex and physical appetite, but it restricts how much we can care. The thin story also means that another burst of movement must often provide the interest that a developing character might have supplied. Yet the film understands something useful about body horror: an unwanted change can frighten us before we understand what it means. A salaryman becoming industrial machinery invites thoughts about work and the uses to which bodies are put, without requiring a speech to announce them. Its sexual grotesquery also prevents the machinery from becoming a tidy symbol with one approved explanation. The humour is usefully unpleasant, too: the physical exaggeration can be funny without making the pain disappear. There is a point at which the frantic pace begins to flatten the differences between one grotesque image and the next. Anyone looking for the suspense of waiting for a threat will find little relief in a film this occupied with showing its effects on flesh. Choose it for that bodily discomfort and the ingenuity that keeps renewing it; allow a quiet interval afterwards. *Fi1m score 82, published 16 September 2026.* ## What the critics say Most critics respond strongly to Tetsuo: The Iron Man, with praise concentrated on Tsukamoto’s handmade effects, harsh black-and-white imagery and aggressive sound. The reviews find its fusion of flesh and machinery disturbing, inventive and often darkly funny, with stop-motion and prosthetics giving the bodily transformations their force. Several also see more than provocation in the violence and sexual imagery, reading the film through technological change, metal fetishism and the unstable boundary between people and their industrial surroundings. The spread is wide, however, and enthusiasm for the images does not always extend to the storytelling. The New York Times finds little narrative sense but values the perverse humour, while Radio Times treats the plot largely as an excuse for nightmarish sex and violence. Empire also finds pretension alongside forceful imagery and humour; the disagreement centres on whether the film’s relentless assault sustains its fascination or becomes an ordeal. ### Reviews we read (11) - **Evening Standard**, Steve Morrissey (90/100, inferred): The 1988 film is called a cheap but very nasty groundbreaker full of great stop-frame effects, following a man turning into a mechanoid with industrial machinery sprouting from his body. It is praised as gigglingly gruesome and a landmark of inventiveness and camerawork. [Read](https://www.standard.co.uk/showbiz/glory-of-the-gory-6316667.html) - **Film Comment**, Grady Hendrix (90/100, inferred): The critic calls Tetsuo a body-horror nightmare and a tortured scream about a salaryman whose body sprouts metal tumors and a penis drill. It highlights Tsukamoto's intense, handmade style using 8mm, stop-motion and aggressive sound design as part of his most riveting work. [Read](https://www.filmcomment.com/article/solid-metal-nightmares-the-films-of-shinya-tsukamoto/) - **Little White Lies**, Sam Moore (80/100, inferred): The film turns body horror on its head by focusing on technology rather than biology, presenting a dystopian vision of transhumanism as a monstrous, inevitable fusion of flesh and metal. [Read](https://lwlies.com/in-praise-of/tetsuo-the-iron-man-and-the-dark-side-of-transhumanism) - **Los Angeles Times**, Kevin Thomas (80/100, inferred): Tsukamoto’s film is grisly yet fascinating and even darkly humorous, a bravura horror picture in which the relentless mutation of man into metal casts a compelling spell. With harsh black-and-white images and terrific control, it creates a world as grotty and weird as Lynch’s Eraserhead and projects a disturbing yet often shockingly hilarious vision. [Read](https://www.latimes.com/archives/la-xpm-1992-07-09-ca-2544-story.html) - **Slant Magazine**, Ed Gonzalez (80/100, inferred): The critic finds Tsukamoto’s fetishistic film worthy of comparison to Cronenberg. It evokes an industrial flux between humanity and its surroundings through the homoerotic transformation of its characters. [Read](https://www.slantmagazine.com/film/tetsuo-the-iron-man/) - **The New York Times**, Stephen Holden (70/100, inferred): The 67-minute black-and-white film is a David Cronenberg-style fantasy reimagined as grungy industrial rock music, with hyperkinetic pacing and wildly contorted acting that also evokes Japanese sci-fi cartoons. It makes little sense as a story but is driven by a perverse sense of humor. [Read](https://www.nytimes.com/1992/04/22/movies/review-film-forgoing-the-flesh-for-metallic-pleasures.html) - **Radio Times**, Robert Sellers (2/5): The plot of a businessman turning into a metallic mutant is merely an excuse for surreal nightmarish images of violence and sex; the short black-and-white feature with minimal dialogue and techno soundtrack will be seen as either pretentious rubbish or a classy art movie. [Read](https://www.radiotimes.com/movie-guide/b-ckqspw/tetsuo-the-iron-man/) - **Empire**, empire (30/100, inferred): The black-and-white film follows hit-and-run victims who mutate into half-human, half-machine monsters engaging in violent and sexual acts. It is described as painful, funny, pretentious and pointed, with strong screen imagery including a notable drill penis scene. [Read](https://www.empireonline.com/movies/reviews/tetsuo-review/) - **Collider**, Orestes Adam (90/100, inferred): The critic calls the film one of body horror's masterworks for its effective use of low-budget black-and-white imagery and handmade prosthetics to depict a man's gruesome metallic transformation. It singles out the film's disturbing, multifaceted blend of depraved character study, sexual nightmare, and cyborg elements that leaves viewers stunned. [Read](https://collider.com/body-horror-tetsuo-the-iron-man/) - **/Film**, Witney Seibold (85/100, inferred): The piece calls the film an essential, viscerally powerful lo-fi cult classic with a punk rock attitude that shocks through its themes of mechanized modernity and metal fetishism. It singles out the gritty, aggressive visuals and breakneck pacing as elevating it to greatness. [Read](https://www.slashfilm.com/886424/the-daily-stream-tetsuo-the-iron-man-and-the-horrors-of-mechanized-modernity/) - **Eye for Film**, Anton Bitel (80/100, inferred): The critic describes the film as a singular monstrosity blending punk, cyberpunk, body horror and surrealism, with an arresting vision of creation and destruction as coexisting drives. It singles out the film's introduction of Tsukamoto to international audiences through its unforgettable imagery.
