15’Tetsuo: The Iron Man' (1989)

Tetsuo: The Iron Man

Shinya Tsukamoto’s cyberpunk horror gemTetsuo: The Iron Manopens with quite a horrendous bang as a young man viciously shoves a piece of scrap metal through his thigh before being struck in a hit-and-run accident in a scene that sets the grim tone for the remainder of the flick. When a Japanese salaryman accidentally strikes the aforementioned victim with his car, he begins to sprout metal pieces all over his body that transforms him into a man/machine hybrid.

The Salaryman and his victim, aptly known as the Young Metal Fetishist (played by Tsukamoto), begin to find their bodies becoming one as they are both consumed by metal and are brutally mutated, with the two merging in a horrific final act. Favorably compared to the work ofbody horror king David Cronenbergas well as both Sam Raimi and David Lynch,Tetsuo: The Iron Manis a deeply frenetic and unapologetically extremist low-budget film that features manic storytelling and some truly nightmarish visuals.

14’Possession' (1981)

Possession

The story ofPossessionfocuses on a couple whose marriage begins is slowly disintegrating.

The husband, desperate to understand what is happening with his wife (Isabelle Adjani in the best performanceof her career), hires a private eye, who leaves him with more questions than answers. When the reason for her behavior is revealed, you’ll be shocked to your bones.

Possessionis the type of movie that demands a certain mindset before sitting down to see it. This body horror film holds off the graphic violence and disturbing visuals right until the movie’s end, and it’s totally worth the wait. This disturbing feature is written and directed by Andrzej Żuławski, and it’ll have you wondering what exactly is going on in the mind of the director. It’s very scary because it’s completely disorienting and pushes for a surrealistic tone that’s fully accomplished in the iconic third act.

13’The Stuff' (1985)

The Stuffis a movie written and directed by Larry Cohen; it’s a satirical piece starring working actors such as Michael Moriarty, Andrea Marcovicci, and Garrett Morris. The film presents a world where the mysterious, addictive dessert-like substance becomes a nationwide obsession, with several people refusing to eat it while investigating why this product seems to have taken over everyone so quickly. It’s afunny but blunt critique of consumerismand the dangers of blind conformity.

Some of the best body horror movies have the silliest and over-the-top plots you may imagine. Picture this scenario for a moment: a group of artic miners suddenly find a white, glob-like substance in the icy parade. They take a bite of it, and it tastes good! What are they to do with this finding? Well, what else but sell it in the open market as a food replacement? They even have a catchy name for it that also makes a great title. As funny as it sounds, The Stuff is very unsettling because, to be honest, it hits a little bit too close to home.

It would be so easy to fill this list withmost of David Cronenberg’s works.Shiversis his third film, and it’s one that sinks hard into depravity with body horror elements. The film is also written by Cronenberg, and the cast features Paul Hampton, Joe Silver, and Lynn Lowry. It’s quite scary because of its practical effects which make the threat a bit more tangible, and also the sexual element of the epidemic simply makes it a cautionary tale about STDs that most viewers will feel compelled to observe.

11’The Thing' (1982)

Being trapped in the Arctic is a scary enough prospect, but when you have a bloodthirsty alien possessing people around you, it only adds to the discomfort. John Carpenter left his stamp on the body horror genre with his tense and atmospheric remake ofThe Thingstarring Kurt Russell. The film relies on physical horror as the titular monster jumps from a dog to a human host and evolves throughout. The practical effects here are grotesque yet creative and are considered among some ofthe best effects in horror.

Carpenter ratchets up the intensity throughout, casting plenty of ambiguity on what form the creature could be taking. The arctic setting adds to the bleak nature of the film, andEnnio Morricone’s haunting scoreperfectly complements the mood.The Thingis an example of how the body horror genre can lend itself naturally to suspenseful and taut filmmaking, and Carpenter intelligently crafts an exquisitely unnerving game of cat and mouse.

With its tight pacing, strong visuals, unique setting, and imaginative storytelling,The Thingis an example of the body horror genre at its most richly crafted, resulting in a visceral and captivating experience.

10’Martyrs' (2008)

Laugier wanted the audience to understand and be a forced spectator to the tremendous violence and pain represented in the spine-tingling picture.

TheFrench modern horrorfilmMartyrscaused quite the stir upon its release, with a man collapsing at one screening and a woman vomiting due to the graphic nature of the brutal flick. It is widely considered a prime example of a new-era French horror film and has been praised as one of the greatest horror films of the 21st century, with both Rolling Stone and IGN ranking it on their respective lists.
