We all secretly believe that we would never join a cult. We may be fascinated by the inner mechanics of these insidious groups and go down endless rabbit holes exploring their destructive behavior. But deep down, we’re all convinced that we would be able to sniff out communal manipulation and see a cult leader coming a mile away. Of course, every person who’s ever found themselves in such a group has likely had the same internal belief. We like to see ourselves as mentally superior and aware when we’re being conned by the people around us. But successful cult leaders are experts at finding covert ways to infiltrate our minds and convince us to override our better judgment.

And the terrifying conman at the heart of Mark Anthony Green’s Opus already has an ace in the hole. A world-famous musician and celebrated pop icon, Moretti (John Malkovich) uses his massive fame and musical talent to amass a group of loyal followers who will stop at nothing to take over the world. He is a modern evolution of this terrifying archetype and an omnipresent danger to all of his fans. Sinister and powerful, Moretti follows a terrifying lineup of cinematic cult leaders, each an expert in persuasive control. Purporting to be inspirational trailblazers, these covert villains present a unique version of their own utopia and claim to have the keys to eternal happiness. Who wouldn’t want to follow them into the abyss?

In celebration of Moretti’s arrival, we’re revisiting a handful of the scariest cult leaders in horror. Read on, cower at this cult of personality, and see if Moretti stacks up to the tallest of terrors below by seeing Opus in theaters now. Let us know if we missed any in the comments.

Lord Summerisle – The Wicker Man

This titan of the folk horror genre also presents one of the genre’s most terrifying cults. Robin Hardy’s 1973 brings us to Summerisle, a remote Scottish village where residents practice pagan rituals in the broad light of day. Sergeant Neil Howie (Edward Woodward) arrives by seaplane to investigate the disappearance of a young girl named Rowan (Gerry Cowper) who was last seen preparing for the community’s upcoming May Day festivities. Taken aback by what he views as barbaric rites, Howie vows to find the girl despite her own family’s disinterest. He interviews the island’s wealthy landowner, Lord Summerisle(Christopher Lee), the descendant of a Victorian agronomist who developed unique strains of fruit trees designed to thrive on the island.

To rally the citizens around this risky venture, he convinced them to abandon their Christian beliefs and return to their ancestral paganism to ensure agricultural abundance. But following a disastrous harvest season, Lord Summerisle has rallied his followers to orchestrate an elaborate human sacrifice in hopes of ensuring a prosperous crop in the coming year. Lee’s Lord Summerisle embodies the horrific juxtaposition of a cult leader’s skill. The Wicker Man ends in an act of grisly violence as joyful onlookers sing in exultation. This charismatic master has successfully convinced them to abandon their collective morality and murder an innocent for their own survival.

Isaac – Children of the Corn

Most cult leaders take years to hone their powers of persuasion, but the spiritual powerhouse in Gatlin, Nebraska developed this skill at an early age. Stephen King’s iconic short story may be the US parallel to Hardy’s UK classic, putting an American spin on ritualistic violence. To the outside eye, this rural town has been abandoned by its residents and left to ruin. But unfortunate visitors soon realize that Gatlin is actually home to a violent cult of children who sacrifice adults to a mysterious deity they call He Who Walks Behind the Rows.

Fritz Kiersch’s film adaptation condenses King’s sprawling timeline by introducing the young cult with a blood-soaked flashback. A child preacher named Isaac oversees a vicious massacre of the town’s adults led by strongman and psychopath Malachai (Courtney Gains). Now each year is marked by ceremonial sacrifice as members of the cult reach the age of 19. King’s short story explores the dangerous reasoning of impressionable children and the insidious nature of American rurality. Kirsch’s version may be slightly less nihilistic, but his proselytizing young cult leader has become one of the genre’s most terrifying figures.

Christabella – Silent Hill

While some cult leaders rule with fear and intimidation, others maintain power by exploiting tragedy and fear. Christabella (Alice Krige) leads the demoralized Brethren of Silent Hill, West Virginia by preying on their vulnerabilities while creating perpetual enemies to blame. Once an elementary school principal and community figurehead, Christabella preached purity and sacrifice throughout the isolated mining town before turning the residents on one of her own. Targeting an unwed mother, this cruel woman stigmatized an innocent child and attempted to purify the young “witch” with fire. But this sadistic ritual spins out of control, sparking an underground blaze that continues to burn. With the city in ruins, she has further exploited her followers’ justified fear by casting out troublesome outsiders and burning them at the stake. Not only must the Brethren fear the roaming mutations created by the disaster, but they’re forced to live by Christabelle’s command or face becoming her latest target. In a haunted town filled with zombified nurses, gigantic bugs, and a powerful monster known as Pyramid Head, this terrifying female cult leader remains Silent Hill’s most dangerous monster.

The Castevets – Rosemary’s Baby

We first meet this unassuming couple just moments after a horrific tragedy. A young woman named Terry (Victoria Vetri) has just fallen from a high window of the Bramford when Roman (Sidney Blackmer) and Minnie Castevet (Ruth Gordon) stroll onto the scene. Dressed to the nines, they’re devastated by the death of their troubled houseguest but waste no time befriending Guy (John Cassavetes) and Rosemary Woodhouse (Mia Farrow), a new couple to the building. Minnie is overjoyed at the news that Rosemary is pregnant and begins sharing unusual home remedies along with high-profile connections.

But as Minnie exerts more upsetting control, Rosemary begins to fear that this altruistic couple may have sinister intentions. As her due date approaches, Rosemary investigates the truth about Roman’s past. The son of a powerful occult practitioner, he now leads a satanic cult located in the luxury building. Not only have they wooed Guy with promises of fame and fortune, this unassuming elderly couple have been manipulating Rosemary for months and may be planing to steal her newborn baby. This harrowing film was an instant success, shocking audiences with its unrelenting paranoia and a demonic cult hiding in plain sight. Can we trust our friendly neighbors or does evil truly lurk behind every door?

Mademoiselle – Martyrs

Another of horror’s most sinister cults is led by an unassuming elderly woman. Mademoiselle (Catherine Bégin) is the leader of an underground organization dedicated to sadism, cruelty, and violence. On an idyllic morning in the Belfond home, a young woman named Lucie (Mylène Jampanoï) barges in to slaughter each member of the nuclear family. Her friend Anna (Morjana Alaoui) rushes to the scene of this gruesome massacre only to find a secret passageway leading to an underground lair. Trapped in these sterile tunnels, Anna becomes the latest prisoner of a bespectacled grandmotherly figure.

Mademoiselle explains that the Belfonds were followers of a devious cult consumed with exploring life beyond death. They kidnap and torture young women hoping to create martyrs with the ability to transcend their humanity and glimpse what awaits in the afterlife. After weeks of brutal beatings, isolation, and the systematic removal of her skin, Anna finally reaches this excruciating state and is prepared by the cult to deliver her message. The calculated and cold Mademoiselle may be one of the genre’s most sadistic villains, couching her murderous intent in an altruistic search for the secrets of life. Pascal Laugier’s punishing film does not offer easy answers, but points a damning finger at those who would prey on the innocent for minimal gain.

David – The Invitation

Though David (Michiel Huisman) may not engage in overt torture, his tactics are arguably just as cruel. Eden (Tammy Blanchard) meets this charismatic man while attending grief counseling in the wake of her young son’s death. Two years later, the couple throw a lavish dinner party designed to introduce Eden’s friends to The Invitation, a bizarre brand of spirituality. Her ex-husband Will (Logan Marshall-Green) attends, hoping to continue his own healing journey, but bristles at David’s tone deaf presentation and a “brainwashing” program designed to erase his grief.

The party takes an uncomfortable turn as David and his strange friends explain an unorthodox way to release emotional pain. With the pouring out of poisoned wine, the evening descends into calculated violence and a bloody battle to stay alive. Director Karyn Kusama’s conclusion exposes the predatory nature of organized spirituality while presenting David as one small piece of an exploitative ecosystem.

Father – The Sacrament

Of all the murderous manipulators on this list, Father (Gene Jones) may be the most horrific. Inspired by real life cult leader Jim Jones, this devout Christian oversees Eden’s Parrish, a remote commune dedicated to spiritual cleansing and personal growth. Constantly spouting scripture, Father hides behind a veneer of righteousness while stealing his followers’ earthly possessions. Ti West’s found footage nightmare follows a small documentary crew who visit the compound on the eve of an unthinkable tragedy.

Hoping to reconnect with his estranged sister Caroline (Amy Seimetz), Patrick (Kentucker Audley) arranges an interview with the group’s charismatic head. But the conversation quickly sours and filmmakers Jake (Joe Swanberg) and Sam (AJ Bowen) begin to fear for their lives. When a small group of disillusioned followers beg for help, Father makes a desperate attempt to maintain control. He orders his followers to die by suicide and murders anyone who dares to resist. Based on the horrific massacre at Jonestown in Guyana, West’s harrowing film is a loose adaptation of one of the greatest tragedies in American history.
