Best Exorcism Horror Movies to Watch

The seismic impact of William Friedkin‘s The Exorcist defined the horror genre, turning exorcism into a spectacle of religious warfare. But beyond this canonical masterpiece, the theme has found new life, becoming a diagnostic tool for society’s anxieties.

These films use the violation of body and soul not to explore the conflict between Heaven and Hell, but to dissect the human psyche. Possession becomes the physical manifestation of generational trauma, the symptom of a crisis of faith in a secularized world, the psychological collapse in the face of unbearable pain. Art-horror” cinema has revitalized the subgenre, shifting the focus from the external demon to the demons we cultivate within ourselves.

This guide is a path that unites the fundamental pillars, from the most celebrated films to the most daring independent productions. From the “Satanic Panic” paranoia of the ’80s to the crisis of faith in institutions captured by found footage, to the current wave of “elevated horror” that frames possession as an inherited sickness of the soul. Here is a selection of works that do not just aim to scare, but dare to question.

What is exorcism?

Exorcism is the spiritual practice of banishing satanic forces, jinn, or other spiritual entities from a person or place believed to be possessed. Depending on the exorcist’s spiritual beliefs, this may be accomplished by compelling the entity to swear an oath, performing rituals, or simply ordering it to leave in the name of a higher power. The practice is ancient and is part of the belief systems of many cultures and religions.

The practice of listening to or reciting the Paritta began very early in the history of Buddhism. It is a Buddhist practice of reciting specific verses from the Pali canon to repel demons. In Sri Lanka, Sinhalese Buddhists invoke the Buddha along with the divine being Suniyam to manage and combat evil forces. supernaturalevil spirits in a ritual called yakto. The ritual on Ghost Exorcist Day becomes part of Tibetan custom. Temples and abbeys throughout Tibet organize large spiritual dance events, the largest at the Potala Palace in Lhasa. Families clean their homes and consume a noodle soup called “guthuk.” At night, individuals carry torches, shouting the words of exorcism.

Prayer in Christian exorcism

In Christian practice, the individual performing the exorcism, known as an exorcist, is typically a member of the Christian Church. The exorcist may use prayers and spiritual methods, gestures, signs, icons, amulets, and so on. The exorcist typically invokes God, Jesus, or various angels and archangels to intervene in the exorcism. Protestant Christian exorcists most often believe that the authority granted to them by the Father, the Son, and the Holy Spirit (the Trinity) is the sole source of their ability to cast out devils. Possessed individuals are not considered evil in themselves, nor responsible for their actions, as they are believed to be under the power of a satanic force that causes harm to themselves and others.

Exorcists consider exorcism a remedy, not a punishment. Traditional rites take this into account, ensuring there is no violence against the possessed. There are biblical verses, such as John 13:27, that implicitly communicate that demonic possession can be voluntary, as demonstrated in people like Judas Iscariot, who voluntarily sold himself to the Devil. Exorcism began to decline in the United States in the 18th century and was almost completely eliminated until the second half of the 20th century, when the general public saw a sharp increase due to the prominence exorcisms were gaining. There was a 50% increase in the variety of exorcisms performed between the early 1960s and the mid-1970s.

Catholic exorcism

In Catholicism, exorcisms are performed in the name of Jesus Christ. A comparable practice is the ministry of deliverance. The difference between the ministry of deliverance and exorcism is that exorcism is performed by priests who have received sole approval from the Catholic Church, while the ministry of deliverance is a prayer for people who are distressed and wish to heal psychological wounds caused by demons.

In Catholic practice, the individual who performs the exorcism, called an exorcist, is a specially appointed priest. The exorcist recites prayers according to the rite and may use spiritual objects, icons, and sacramentals. The exorcist invokes God, specifically the Name of Jesus Christ, along with members of the Church Triumphant and the Archangel Michael to intervene in the exorcism. According to Catholic tradition, a certain number of weekly exorcisms over several years are often necessary to expel a deeply rooted satanic force. The Prayer of St. Michael against Satan and the Rebel Angels, attributed to Pope Leo XIII, is considered the Catholic Church’s greatest prayer against cases of demonic possession. The Holy Rosary also has intercessory and exorcising power.

The Best Independent Exorcism Horror Films to Watch

When Evil Lurks (2023)

In a remote rural Argentinian town, two brothers discover a “rotten”—a man possessed by a demon that is about to be “born.” By ignoring the strict rules for dealing with such entities, they accidentally trigger a possession epidemic that spreads like a physical and spiritual plague. They are forced into a desperate flight through a landscape where the traditional protections of the Church and state have completely failed.

Demonic possession is reimagined here as a highly contagious disease, stripping away the religious mystery and replacing it with the visceral horror of a biological outbreak. The film is essential for its “secularization” of evil, where exorcism is no longer a sacred rite but a failed, underfunded public service. It offers a bleak, unflinching look at social breakdown and the terrifying speed at which an ancient evil can become a mundane, bureaucratic catastrophe.

Godless: The Eastfield Exorcism (2023)

Inspired by a true story, the film follows Lara, a woman struggling with diagnosed mental illness whose fanatical husband becomes convinced she is possessed. He pressures her to stop her medical treatment and hands her over to a self-proclaimed exorcist who performs a brutal, unsanctioned ritual. What was meant to be a spiritual cleansing quickly devolves into a harrowing ordeal of physical torture and psychological abuse.

This Australian production is a stark indictment of religious fundamentalism and medical ignorance. By framing the “possession” through the lens of paranoid schizophrenia, the film shifts the horror from the supernatural to the human. It is a necessary, disturbing exploration of how patriarchal control and faith-based delusions can be far more lethal and terrifying than any literal demon, highlighting the tragic consequences of institutional and domestic failure.

Talk to Me (2022)

A group of teenagers discovers they can conjure spirits by grasping a mysterious, ceramic-covered hand. They soon become addicted to the 90-second rush of temporary possession, recording their sessions for social media clout. However, when Mia—still reeling from her mother’s death—pushes the ritual too far, she unleashes malevolent forces that blur the lines between the living and the dead, leading to a devastating collapse of her reality.

The film serves as a brilliant modern allegory for drug addiction and the commodification of trauma in influencer culture. Possession is treated not as a religious terror, but as a recreational high sought by a nihilistic generation. It is a standout for its raw emotional intensity and its critique of a society that transforms even the most sacred or dangerous experiences into shareable content, ultimately showing the high cost of using the supernatural as an escape from grief.

Attachment (2022)

Maja, a Danish actress, falls in love with Leah, an academic from London. When Leah suffers a mysterious seizure, Maja follows her back to the Orthodox Jewish neighborhood where Leah lives with her overprotective mother, Chana. Maja soon finds herself entangled in a web of Jewish folklore and suspicious rituals, as she begins to believe that Chana is hiding a sinister secret involving a Dybbuk.

This film masterfully blends a queer romance with Jewish mythology, redefining the concept of “attachment” on three levels: romantic, familial, and supernatural. It is an essential watch for its nuanced portrayal of the Dybbuk as a manifestation of pathological, suffocating maternal love rather than simple malice. The horror is rooted in the toxic bonds of protection, making the eventual “exorcism” a complex emotional untangling of generational trauma and obsession.

The Medium (2021)

A documentary crew follows Nim, a shaman in a rural Thai village who serves as a vessel for the local deity, Bayan. The footage takes a dark turn when Nim’s niece, Mink, begins exhibiting terrifying, erratic behavior that suggests she is being possessed by a chaotic and far more ancient evil. As rituals fail and the violence escalates, the community faces a total spiritual collapse that threatens to consume everyone involved.

This found-footage masterpiece explores “spiritual entropy,” showing what happens when sacred boundaries are broken and ancient traditions lose their power. By moving beyond Judeo-Christian tropes, it provides a visceral look at Isan shamanism and ancestral curses. It is a landmark in folk horror, portraying a world of supernatural anarchy where faith is not a shield, but a vulnerable gateway to a primal, uncontrollable darkness.

The Exorcism of God (2021)

Father Peter Williams is an American exorcist in Mexico haunted by a failed ritual from eighteen years ago, during which he was briefly possessed and forced to commit a terrible sin. When the same demon returns to possess a young woman in a local prison, Peter is forced to confront his own suppressed guilt and the shame that has compromised his spiritual authority, leading to a confrontation that tests the limits of his priesthood.

The film modernizes spiritual warfare by making it a deeply psychological battle rooted in shame and memory. Unlike traditional narratives where the priest is a pure vessel of divine power, here the protagonist’s “spiritual armor” is cracked by his past transgressions. It is a compelling entry in the genre because it suggests that the most dangerous weapon a demon possesses is not raw power, but the human capacity for self-loathing and the secrets we keep from ourselves.

The Old Ways (2020)

Cristina, a Mexican-American journalist, returns to her birthplace in Veracruz to investigate local witchcraft. Her skepticism is shattered when she is kidnapped by a group of locals, including a “bruja,” who are convinced she is possessed by a demon. Confined to a small room, she is forced to undergo ancient, grueling purification rituals that challenge her modern worldview and force her to reconnect with a heritage she had long rejected.

This film offers a distinct Latin American perspective on exorcism, framing the demon as a metaphor for cultural alienation and suppressed trauma. The “old ways” of the ritual serve as a path to reclaiming a lost identity, suggesting that spiritual salvation requires a literal and figurative return to one’s roots. It is an innovative work that replaces the sterile Vatican aesthetic with earthy, visceral folk magic, making the exorcism a profound journey of self-discovery.

Anything for Jackson (2020)

An elderly, seemingly kind-hearted couple who are members of a satanic cult kidnap a pregnant woman in a desperate attempt to perform a “reverse exorcism.” Their goal is to channel the soul of their deceased grandson, Jackson, into the woman’s unborn child. However, their lack of expertise leads them to summon a host of unintended, terrifying spirits that begin to infest their quiet suburban home.

This film subverts the genre by portraying its “villains” as a grieving, loving couple whose monstrous actions are driven by a relatable human tragedy. It is a standout for its dark humor and its unsettling depiction of grief as an all-consuming force that can make cosmic evil seem like a logical solution. The horror arises from the clash between mundane domestic life and the chaotic, grotesque entities they unwittingly invite across the threshold.

Saint Maud (2019)

Maud is a reclusive, devoutly Catholic nurse who becomes obsessed with “saving” the soul of her terminally ill patient, Amanda, an atheist former dancer. Maud’s zeal soon spirals into a series of ecstatic, sensory hallucinations that she interprets as direct communication with God. As her isolation deepens, her divine mission becomes increasingly violent, blurring the lines between religious salvation and a total psychiatric collapse.

Rose Glass’s debut is a chilling dissection of the thin line between religious ecstasy and pathological trauma. By portraying the “possession” as something divine rather than demonic, the film explores how a desperate need for meaning can turn faith into a destructive weapon. It is an essential work of psychological horror, culminating in one of the most devastating final shots in cinema history that forces the audience to confront the tragic reality behind Maud’s visions.

The Lighthouse (2019)

In the late 19th century, two lighthouse keepers—the grizzled Thomas Wake and the younger Ephraim Winslow—are stranded on a remote, storm-lashed rock. As isolation, alcohol, and cabin fever set in, their relationship descends into a claustrophobic power struggle. Mythological visions and repressed secrets emerge, transforming their confinement into a surreal purgatory where time and sanity lose all meaning.

Robert Eggers presents the “possession” not of a body, but of a location and a psyche. The film is a masterclass in atmospheric dread, utilizing a 1.19:1 aspect ratio and expressionist black-and-white cinematography to evoke a sense of primordial trap. It is a definitive exploration of toxic masculinity and the breakdown of language, suggesting that the ultimate horror is being left alone with the monsters created by one’s own mind and the crushing weight of solitude.

The Cleansing Hour (2019)

Max and Drew run a successful webcast that features “live” exorcisms, which are actually carefully orchestrated fakes designed for viral fame. Their cynicism is tested when a real demon possesses the actress during a broadcast, taking the crew hostage and forcing them to confess their darkest secrets to an audience of millions. The demon hijacks the platform, turning the stream into a brutal, high-stakes game of truth or dare.

This film is a sharp, satirical take on influencer culture and the hunger for authenticity in a digital world. The demon acts as a perverse “content moderator,” exposing the hypocrisy of the protagonists in front of their global followers. It is a fast-paced, entertaining thriller that uses the possession trope to comment on how we’ve commodified the sacred, showing that in a world of online fakery, sometimes only a demon can force a moment of honesty.

Hereditary (2018)

Following the death of their secretive grandmother, the Graham family begins to fall apart as they discover terrifying secrets about their lineage. Their grief turns into a nightmare when they realize they are pawns in a generational plot to summon the demon Paimon. As the family’s mental health deteriorates, Annie and her son Peter are drawn into a predetermined fate where every attempt to escape only leads them closer to the cult’s ultimate goal.

Ari Aster’s debut is the definitive modern study of possession as a metaphor for inherited trauma and mental illness. The film succeeds because it treats the “demon” as an extension of the family’s pre-existing dysfunction and grief. It is a masterpiece of dread that replaces jump scares with a suffocating sense of inevitability, proving that the most terrifying ghosts are the ones woven into our own DNA and the unprocessed pain passed down through generations.

The Devil’s Doorway (2018)

In 1960, two priests are sent by the Vatican to an Irish “Magdalene Laundry” to investigate a statue of the Virgin Mary that reportedly bleeds. Documenting their search on 16mm film, they uncover the horrific abuse and systemic cruelty inflicted by the nuns upon the “fallen women” in their care. As they dig deeper into the basement, they realize that the institutional evil has manifested a literal, demonic presence.

This found-footage film uses the real-life historical horror of Ireland’s laundries to ground its supernatural elements in a legacy of actual human atrocity. The “possession” here is a symptom of institutional sin, suggesting that the most terrifying demons are invited in by religious hypocrisy and the abuse of power. It is a bleak, effective entry that uses the camera to “exorcise” a shameful chapter of history, showing that the devil thrives in places where mercy is absent.

Possum (2018)

Philip, a disgraced puppeteer, returns to his decaying childhood home carrying a hideous, spider-legged puppet with a human face. No matter how many times he tries to discard or destroy the puppet, it returns to haunt him, symbolizing his inability to escape the repressed memories of the abuse he suffered at the hands of his uncle. His journey is a grueling attempt to “exorcise” his own past.

The puppet, “Possum,” serves as a physical container for the protagonist’s trauma, making this a profound exploration of psychological possession. The film is a masterstroke of tone and grimy aesthetic, focusing on the inescapable nature of deep-seated emotional scars. It is essential for its portrayal of healing not as a complete cleansing, but as a painful, necessary confrontation with the “monsters” that trauma has left behind in the mind’s dark corners.

Luz (2018)

Luz, a young Chilean taxi driver, arrives at a police station in a daze. A psychologist attempts to reconstruct her night through hypnosis, unaware that Luz is being pursued by a demonic entity that has haunted her since her days at a strict Catholic school. During the session, the demon begins to “migrate” between those present, using the power of memory and narration to bridge the gap between hosts.

Shot on 16mm with an aesthetic that evokes 70s European art-house horror, the film treats possession as a “memetic virus” that travels through language and memory. It is a minimalist, dreamlike experience that avoids genre clichés in favor of a hypnotic, experimental atmosphere. It is a must-watch for those who enjoy horror that explores the fluid nature of identity and the idea that our own stories can be the conduits for our destruction.

The Wailing (2016)

In a quiet South Korean village, a series of gruesome murders and a bizarre skin disease coincide with the arrival of a mysterious Japanese stranger. A local bumbling policeman, Jong-goo, is forced into a desperate battle of faith and suspicion when his daughter begins showing symptoms of possession. He is caught in a crossfire between a local shaman, a mysterious woman in white, and a potential demon.

This epic horror film is a terrifying study of moral and spiritual ambiguity where every choice the protagonist makes leads to further damnation. It subverts the exorcism genre by making faith a weapon used against the believer, as Jong-goo is unable to distinguish between his saviors and his destroyers. It is an essential work for its masterful control of tone and its bleak conclusion that suggests in a world of conflicting truths, the devil always wins by sowing doubt.

A Dark Song (2016)

Consumed by grief over the murder of her son, Sophia hires a misanthropic occultist to perform a months-long, grueling ritual in a secluded house. Her goal is to summon her “guardian angel” to grant her a wish for revenge, but the ritual requires absolute mental and physical discipline. As the boundaries between reality and the occult blur, the two participants push themselves to the brink of insanity and death.

The film treats occult ritualism with a procedural, clinical realism, making the magic feel tangible and dangerous. It is a “reverse exorcism” where the protagonist is trying to invite a presence in rather than cast it out. It is a powerful metaphor for the grieving process, suggesting that the only way to truly “exorcise” the demons of pain and anger is through an agonizing internal journey toward forgiveness.

The Witch (2015)

In 1630s New England, a devout Puritan family is banished to the edge of a wild forest. When their infant son vanishes, the family is consumed by religious paranoia, accusing the eldest daughter, Thomasin, of witchcraft. As their crops fail and their bonds break, the family’s own fanatical piety creates an environment where the devil’s influence is the only remaining explanation for their suffering.

Robert Eggers’ “folk-tale” is a masterpiece of period-accurate horror that explores the dangers of religious repression and the fear of female autonomy. It portrays the “witch” as both a literal threat and a projection of the family’s own spiritual sickness. The film is essential for its atmospheric dread and its provocative ending, which frames Thomasin’s eventual embrace of the dark as a liberating escape from a patriarchal system that had already condemned her.

The Blackcoat's Daughter (2015)

Kat and Rose are two students left behind at a prestigious Catholic boarding school during winter break. As an unseen, malevolent presence begins to influence the vulnerable Kat, a third woman named Joan makes a bloody escape from a psychiatric hospital and travels toward the school. The film weaves two timelines together to reveal a tragic story of loss, murder, and demonic devotion.

Osgood Perkins explores possession as a “twisted connection” born from absolute loneliness. Kat’s embrace of the demon is not an act of evil, but a desperate reaction to being abandoned by the adults in her life. The film is a haunting critique of cold, religious institutions that fail to provide genuine human warmth, suggesting that when we leave the most vulnerable alone in the dark, they will find companionship in the shadows.

The Atticus Institute (2015)

Presented as a mockumentary, the film follows a parapsychological research team in the 1970s that encounters Judith Winstead, a woman whose abilities go far beyond simple ESP. When they realize she is possessed by a demon, the U.S. government intervenes to “militarize” the entity for use as a weapon in the Cold War. The experiments quickly spiral out of control, leading to a catastrophic security breach.

This film is a unique blend of paranormal horror and political thriller, using the mockumentary format to provide a sense of clinical authenticity. It is a chilling commentary on institutional arrogance, showing what happens when secular powers attempt to “bureaucratize” absolute evil. It is essential for its distinct take on the genre, where the demon isn’t a soul to be saved, but a weaponized resource that ultimately consumes those who try to own it.

The Taking of Deborah Logan (2014)

A group of graduate students filming a documentary on Alzheimer’s disease follows Deborah Logan as her condition rapidly worsens. However, her behavior becomes increasingly impossible to explain medically, as she displays superhuman strength and occult knowledge. They soon discover that Deborah is being possessed by the spirit of a serial killer trying to complete a ritual through her body.

The film is highly regarded for its clever use of a real medical condition to mask the early signs of a supernatural invasion. Jill Larson’s performance is fearless and physically transformative, creating some of the most unsettling imagery in the found-footage subgenre. It is a standout work because it grounds its horror in the very real, heartbreaking fear of losing one’s mind and identity to an external force.

The Conjuring (2013)

Renowned paranormal investigators Ed and Lorraine Warren travel to a Rhode Island farmhouse to help the Perron family, who are being tormented by an increasingly violent presence. They discover the house is haunted by the spirit of a witch who cursed the land. As the activity reaches a fever pitch, the Warrens must perform an unsanctioned exorcism to save the mother, Carolyn, from total demonic possession.

James Wan’s film revitalized the haunted house and possession subgenres for the 21st century by focusing on atmosphere and classical filmmaking techniques. The film works because it makes the central couple’s faith feel authentic and grounded. It is a masterclass in building tension and is essential for its role in launching a massive horror franchise based on the idea of faith as a practical tool for survival.

The Last Exorcism (2010)

Reverend Cotton Marcus, a charismatic preacher who uses magic tricks and psychological manipulation to “perform” exorcisms, invites a film crew to document his final case in order to expose the practice as a fraud. However, when he meets Nell, a young girl on a remote Louisiana farm, he encounters a force that his rationalism cannot explain, forcing him to confront a real evil that shatters his skepticism.

The film is a brilliant deconstruction of the genre, using the found-footage format to heighten the tension between science and faith. Cotton Marcus is a compelling “shyster with a heart,” and his journey from cynicism to a desperate, true belief is the emotional core of the film. It is an essential work for how it handles ambiguity, keeping the audience guessing until the final, terrifying moments about the true nature of the evil.

REC 2 (2009)

Directly following the events of the first film, a SWAT team and a Vatican priest acting as a health official enter the quarantined apartment building in Barcelona. They soon discover that the “infection” is actually a demonic plague that can be controlled and communicated through the possessed. The mission becomes a claustrophobic fight to retrieve a blood sample from the source of the evil.

This sequel brilliantly shifts the franchise from “biological zombie” horror to supernatural possession. The use of helmet cams provides a terrifyingly intimate look at the chaos, portraying the demon as a viral, intelligent entity that thrives on the interconnectivity of the modern world. It is essential for its innovative blend of tactical action and spiritual horror, showing how the church must adapt to a world of science and urban containment.

The House of the Devil (2009)

Samantha, a college student in need of cash, takes a babysitting job for a strange couple in a secluded mansion during a total lunar eclipse. The job is a setup; the family are members of a satanic cult who intend to use her as a vessel for a demonic ritual. Samantha must fight for her life through a night of slow-building dread and explosive, cult-driven violence.

Ti West’s film is a meticulous homage to the “Satanic Panic” movies of the early 1980s, recreating the era’s look and feel with incredible detail. It is a masterclass in “slow-burn” horror, relying on atmosphere and the audience’s knowledge of genre tropes to build a suffocating sense of unease. It is essential for its disciplined direction and its shocking third-act shift, which subverts the very nostalgia it so carefully established.

Requiem (2006)

Michaela is a young woman from a deeply religious family in 1970s Germany who leaves home for university. When she begins to experience terrifying seizures, she believes they are a spiritual crisis rather than a medical one. Encouraged by her family and local priests to view her condition as demonic possession, she descends into a state of physical and mental ruin as the exorcism rituals begin.

This film is a clinical, realistic look at the tragedy of Anneliese Michel, avoiding horror sensationalism to focus on the human cost of institutional failure. Sandra Hüller’s performance is devastatingly authentic, capturing the agony of a woman caught between her own mind and the expectations of her faith. It is an essential work for its critique of how religious zealotry can mask medical neglect, making the ritual itself the most terrifying part of the story.

Noroi: The Curse (2005)

A paranormal journalist, Masafumi Kobayashi, disappears while investigating a series of bizarre and seemingly unrelated supernatural events. His found footage reveals a complex web involving a psychic child, an obsessive woman, and a long-forgotten demonic entity called Kagutaba. As the links between the victims become clear, the footage reveals a curse that is both ancient and inescapable.

Noroi is a landmark of J-Horror that treats the demonic not as a physical threat to be fought, but as an “epistemological puzzle” to be solved. The film’s strength lies in its sprawling, realistic narrative that rewards close attention, making the viewer feel like they are uncovering a forbidden truth alongside the protagonist. It is essential for its unique structure and its ability to build a sense of inescapable doom through the accumulation of eerie, everyday details.

The Exorcism of Emily Rose (2005)

The film follows the trial of Father Moore, a priest accused of negligent homicide following a failed exorcism on a college student named Emily Rose. The story is told through courtroom testimonies and agghiaccianti flashbacks, presenting a battle between a cynical lawyer who believes Emily had epilepsy and a priest who is certain she was possessed by six demons.

This is a rare example of a “legal thriller horror,” using the courtroom to genuinely interrogate the reality of possession. It stands out for its intellectual ambition, refusing to give the audience an easy answer and forcing them to choose between a scientific or spiritual explanation. Jennifer Carpenter’s physical performance is iconic, making the suffering of Emily Rose feel visceral and tragic rather than just a genre trope.

Demons (1985)

A mysterious man gives out free tickets to a horror movie premiere at the Metropol cinema in Berlin. During the screening, a woman is scratched by a mask in the lobby and transforms into a violent demon. The cinema becomes a trap as the infection spreads through the audience, with the movie on screen seemingly predicting and triggering the real-life carnage in the theater.

Produced by Dario Argento, this cult classic is a high-energy, heavy-metal meta-horror film that explores the “contagious” nature of the genre itself. It is a celebration of splatter and practical effects, portraying the act of watching a movie as a dangerous ritual. It is essential for its wild, uninhibited style and its central theme that horror is a virus that can leap off the screen to possess the viewer.

Possession (1981)

Mark, a secret agent, returns to West Berlin to find his wife, Anna, demanding a divorce. Her behavior becomes increasingly manic and violent, leading Mark to discover that she has started an affair with a grotesque, tentacled creature in a hidden apartment. The two spiral into a mutually destructive madness, with their emotional agony manifesting as literal, bloody monstrosities.

Andrzej Żuławski’s masterpiece is a visceral, surreal allegory for the psychological horror of a dying marriage. The “possession” is an externalization of the characters’ internal chaos, with Isabelle Adjani giving a legendary, career-defining performance. It is a landmark of transgressive cinema that asks whether there is any difference between being possessed by a demon and being possessed by the toxic emotions of a failed relationship.

Alucarda (1977)

Justine and Alucarda are two orphans at a secluded Mexican convent who form an intense, blasphemous bond. After stumbling upon a satanic ritual in a forest crypt, Alucarda becomes possessed, leading to a wave of vampiric violence, blood-soaked orgies, and a total rebellion against the oppressive nuns and priests. The convent becomes a literal hell on earth as the girls embrace the dark.

This “nunsploitation” cult classic is a surreal, visually stunning explosion of transgressive horror. It frames possession as an act of ecstatic liberation from a sterile, prison-like religious environment. It is essential for its painterly aesthetic and its unapologetic blasphemy, portraying the devil as a force of color and sensuality that exposes the gray rot of the church’s repression.

To the Devil a Daughter (1976)

John Verney, an occultist, is asked to protect a young girl named Catherine who has been raised in a mysterious convent. He discovers that Catherine’s father made a pact with a satanic priest to offer his daughter as a host for the demon Astaroth on her eighteenth birthday. Verney must race against time to prevent the ritual and break the generational curse that has haunted Catherine since birth.

This film was Hammer Horror’s final major success, moving the studio away from Gothic sets and into a gritty, contemporary setting. It explores the terrifying idea of “predestined possession,” where a child’s soul is sold before they are even born. It is an essential watch for its bleak tone and its focus on the inescapable consequences of the previous generation’s sins, a theme that would later be explored in Hereditary.

The Exorcist (1973)

When twelve-year-old Regan displays terrifying changes in behavior and appearance, her mother turns to two priests for help: the experienced Father Merrin and the young, doubting Father Karras. Inside a cold, dark bedroom, they engage in a grueling, life-or-death battle against a demon that mocks their faith and forces them to confront their own deepest fears and failures.

William Friedkin’s masterpiece remains the gold standard for the genre because it grounds its supernatural terror in a raw, realistic human drama. It is a profound exploration of the crisis of faith and the power of sacrificial love. More than fifty years later, its practical effects and suffocating atmosphere still have the power to disturb, proving that the struggle for a single soul can be more epic and terrifying than any world-ending catastrophe.

The Devils (1971)

In 17th-century France, Father Urbain Grandier is a charismatic priest whose political influence threatens the power of the State. His enemies use the sexual and religious hysteria of Sister Jeanne, a repressed nun who claims he has possessed her with demons, to orchestrate a public trial. The result is a frenzy of mass exorcisms, torture, and a brutal execution that serves as a tool for political control.

Ken Russell’s controversial film is a scathing critique of the intersection between political power and religious fervor. It shows how the ritual of exorcism can be weaponized by the state to silence dissent and control the masses through fear and spectacle. Based on real historical events, it remains an essential work for its bold, theatrical style and its timely warning about the dangers of using “evil” as a political label.
