In 1983, horror master David Cronenberg was asked why people enjoy scary films. He said it’s because audiences like to confront their fears in a controlled way. While disturbing movies might go beyond typical horror fare, the emotional ride they offer is undeniable. These films challenge us, often exploring the darkest aspects of humanity. Below are 18 films that do just that—and while they may not be the best for a casual movie night, they certainly leave a mark.
18. The Last House on the Left (1972)
Wes Craven’s debut shocks audiences with its raw brutality. Inspired by Ingmar Bergman’s The Virgin Spring, this 1972 film tells the story of a young girl who’s raped and murdered by a group of criminals—only for her parents to take revenge. It’s an unflinching exploration of violence and retribution, with its raw depiction of sexual assault still disturbing audiences today.
17. The Human Centipede (First Sequence) (2009)
Though not a cinematic masterpiece, The Human Centipede gained cult status due to its grotesque concept: a mad doctor surgically connecting three people mouth to anus. The film’s shock value lies entirely in its premise, which makes it more of a gross-out challenge than a horror masterpiece.
16. Cannibal Holocaust (1980)
This notorious exploitation film predated the found footage trend, creating controversy with its extreme violence and the real animal deaths captured on screen. The film’s graphic realism led many to believe it was a snuff film, sparking government investigations. Its scenes of cruelty remain hard to stomach.
15. Henry: Portrait of a Serial Killer (1986)
Michael Rooker’s chilling portrayal of a sociopath in Henry: Portrait of a Serial Killer offers a grim look into the life of a remorseless killer. The film’s raw, documentary-style execution enhances its horror, making Henry’s murders feel disturbingly real and inescapable.
14. Possessor Uncut (2020)
Brandon Cronenberg’s Possessor blends psychological horror with body horror. The film follows an assassin who takes over others’ bodies to commit corporate hits, gradually losing her sense of self. The violence escalates as identity and humanity blur in this deeply unsettling narrative.

11. Inside (2007)
This French horror is not for the faint of heart. A pregnant woman is stalked and tormented by a stranger who wants to steal her unborn baby, leading to some of the most gut-wrenching violence ever committed to film. With its claustrophobic setting and relentless pace, Inside is a terrifying descent into madness.

Park Chan-wook’s Oldboy is not just disturbing—it’s a masterpiece. Oh Dae-su is mysteriously imprisoned for 13 years, only to be released and set on a path of violent revenge. The film’s shocking twist is unforgettable, creating one of the most disturbing yet powerful endings in modern cinema.
8. Audition (1999)
In Takashi Miike’s Audition, a widower’s attempt to find love through a fake audition turns into a nightmare. His chosen partner, Asami, is not what she seems, and the film’s slow build leads to a horrifying, torturous climax that still resonates as one of the most disturbing sequences in film history.
7. Funny Games (1997/2007)
In Funny Games, director Michael Haneke explores senseless violence as a family is held hostage by two men at their vacation home. The film’s cold, detached approach to violence, paired with its meta-commentary on the audience’s role in enjoying it, creates an unbearably tense atmosphere.
6. Martyrs (2008)
Martyrs begins as a supernatural horror but quickly turns into something more brutal. The film focuses on a secret organization that tortures women in a quest to unlock the secrets of the afterlife. Its depiction of extreme suffering, particularly a shocking flaying scene, makes it one of the most difficult films to endure.
5. Come and See (1985)
This anti-war film from Russia doesn’t need fictional monsters to disturb its viewers. Instead, it follows a young boy witnessing the horrors of World War II, with his innocence shattered by the atrocities around him. Come and See is a deeply harrowing, almost surreal experience that showcases the psychological and physical toll of war.
4. Antichrist (2009)
Lars von Trier’s Antichrist is a psychological horror that explores grief, guilt, and madness. As a couple retreats to a cabin in the woods after losing their child, they are drawn into a nightmarish series of events. With its intense sexual violence and disturbing imagery, this film leaves a lasting scar.
3. Irreversible (2002)
Gaspar Noé’s Irreversible is famous—and infamous—for its long, uncut take of a brutal rape, but the film’s disturbing nature goes beyond that single scene. Told in reverse, it challenges viewers’ perceptions of time, morality, and violence, leading to a gut-wrenching conclusion.
2. Salo, or the 120 Days of Sodom (1975)
Pier Paolo Pasolini’s Salo remains one of the most controversial films ever made.

Salo pushes the boundaries of what cinema can depict, and its intense, relentless portrayal of human depravity is unforgettable.
1. Titicut Follies (1967)
Frederick Wiseman’s documentary Titicut Follies is not a fictional horror story—it’s real life.

The unflinching look at the inhumane treatment of these vulnerable individuals makes it the most disturbing film of all time. These films aren’t just about shock—they force viewers to confront unsettling truths about humanity, society, and themselves.
Whether they’re pushing the boundaries of what’s acceptable in cinema or offering disturbing commentary on the world we live in, these 18 films are as hard to watch as they are to forget./
