Twelve key facts, spread across production and cast: the director, top-billed actors, genre classification, total cast size, and the authoritative IMDb identifier that anchors all casting data.

Who are the main cast members of Midnight Mass?

The main cast of Midnight Mass brings together a mix of seasoned actors and fresh faces, all anchored to Crockett Island, the fictional impoverished coastal community at the center of the story. Mike Flanagan assembled this ensemble for his Netflix miniseries released on September 24, 2021, drawing several collaborators from his previous work. The cast spans three generations of actors, from Henry Thomas (whose career dates back to E.T. in 1982) to younger performers like Igby Rigney.

Who plays Erin Greene?

Kate Siegel plays Erin Greene, Riley Flynn’s childhood sweetheart and a schoolteacher on Crockett Island who is expecting a child. Siegel had previously starred in Mike Flanagan’s 2016 film Hush, which she co-wrote. In Hush, she played Madison “Maddie” Young, presented within the film as the author of Midnight Mass—a clever bit of meta-storytelling that connects Flanagan’s filmography. Erin serves as one of the series’ emotional centers as she navigates her pregnancy alongside Riley’s return.

Who plays Riley Flynn?

Zach Gilford plays Riley Flynn, a former venture capitalist who returns to his hometown after spending four years in prison for killing a woman in a drunk driving crash. This backstory provides much of the series’ moral weight. Riley’s journey from successful businessman to convicted felon to someone seeking redemption forms the backbone of the miniseries. Gilford, a Colorado native, brings a weathered authenticity to the role that critics praised in reviews.

Who plays Annie Flynn?

Kristin Lehman plays Annie Flynn, Riley’s devout and forgiving mother. Annie represents a counterpoint to the island’s more zealous religious figures—her faith is genuine rather than performative. She appears committed to welcoming her son home despite community backlash. Lehman, a Canadian actress with extensive television experience, brings warmth to a character who could have easily been overshadowed by the series’ more dramatic personalities.

Who plays Bev Keane?

Samantha Sloyan plays Bev Keane, a zealous, overbearing, and influential member of the church who becomes one of the series’ primary antagonists. Bev’s brand of religious conviction is performative and manipulative—she weaponizes faith to gain social control over the island. Sloyan’s performance drew particular critical attention for its unsettling plausibility. Bev’s actions throughout the series—including controversial choices regarding community members—make her one of the most memorable antagonists in Flanagan’s horror catalog.

Who plays Warren Flynn?

Igby Rigney plays Warren Flynn, Riley’s teenage brother who serves as an altar boy at the church. Warren occupies an interesting position in the Flynn family dynamics—he’s young enough to be impressionable but old enough to question the religious certainty around him. Rigney, a young actor whose career was just beginning with this role, delivers a nuanced performance as a teenager caught between loyalty to his returned brother and the island’s religious community.

The pattern across these main cast pairings shows Flanagan casting actors who can convey moral complexity rather than clear-cut heroism or villainy. Even characters positioned as antagonists have understandable motivations, while protagonists carry shadows from their pasts.

Who plays Monsignor Pruitt in Midnight Mass?

Hamish Linklater plays a dual role as Father Paul Hill and Monsignor Pruitt, representing one of the series’ most audacious casting decisions. Monsignor Pruitt is the aging, beloved priest of Crockett Island who has served the community for decades, while Father Paul is the mysterious young priest who arrives to temporarily replace him after Pruitt suffers a health crisis. The reveal that both characters are played by the same actor becomes central to the series’ plot, as Father Paul’s true nature remains hidden from the congregation.

What role does Monsignor Pruitt play?

Monsignor Pruitt serves as the spiritual backbone of Crockett Island, having ministered to the community through decades of hardship and decline. His health failing, he secretly arranges for Father Paul to replace him, but the true reason for this arrangement—and the nature of what he discovers during a trip abroad—drives much of the supernatural plot. The character represents the old faith of the island, one that was simpler and more community-focused before the dramatic events of the series unfold.

Why did Monsignor Pruitt think the vampire was an Angel?

The series plays deliberately with the question of whether the creature Father Paul (and later Monsignor Pruitt) encounters is genuinely supernatural or divine. Monsignor Pruitt, deeply devout, interprets the being that grants seemingly miraculous healing as an angel rather than recognizing it as a vampire. This misinterpretation stems from his faith-based worldview—he seeks divine justification for what he witnesses. The tragedy is that his interpretation allows him to justify terrible actions that a clearer understanding might have prevented. The series uses this religious framework to explore how faith can blind as well as guide.

Who is the old lady in the cast of Midnight Mass?

While Samantha Sloyan’s Bev Keane is the most prominent “old lady” figure in terms of personality and influence, the cast includes several older female characters who each serve distinct narrative purposes. The term “old lady” likely refers to Bev herself, whose zealous, overbearing presence makes her the de facto matriarch of the church community despite not holding any official title.

Who plays Bev Keane?

Samantha Sloyan plays Bev Keane, described in casting and press materials as a zealous, overbearing, and influential member of the church. Bev quickly establishes herself as the series’ primary antagonist through her manipulation of fellow church members and her ability to weaponize religious rhetoric. Sloyan, whose previous work includes roles in Grey’s Anatomy and The Haunting of Hill House (another Flanagan project), brings an unsettling authenticity to a character who genuinely believes her actions serve divine purpose.

Did Bev Keane poison the dog?

Bev Keane’s actions throughout the series include several morally questionable choices, though the specific question of whether she poisoned a dog requires careful handling to avoid spoilers for the series’ plot twists. What can be confirmed is that Bev demonstrates a willingness to take extreme measures to protect her vision of the community and her understanding of its spiritual mission. The Midnight Mass Fandom Wiki documents her role extensively as one of the series’ most purely antagonistic forces.

Who plays the vampire or angel in Midnight Mass?

The creature in Midnight Mass defies easy categorization. While the series presents what appears to be a vampire—a being that feeds on blood and can spread its condition to others—it frames this creature through a religious lens, with characters interpreting its actions as miracles or angelic visitations. The supernatural being at the heart of the series is not the traditional gothic vampire of Bram Stoker or Anne Rice but something the Midnight Mass Fandom Wiki describes in terms that blend horror with religious transcendence.

What is the vampire in Midnight Mass?

The creature introduced in Midnight Mass operates as a vampire in traditional terms—it requires blood to survive and can transform humans through exposure to its blood—but its presentation in the series deliberately blurs genre categories. The Fandom Wiki notes describe the creature as something that grants apparent miracles (healing, restored mobility) while simultaneously requiring the blood sacrifice that defines vampirism. This ambiguity is central to the series’ exploration of faith versus evidence.

Was the vampire in Midnight Mass an angel?

The series deliberately withholds a definitive answer to whether the creature is supernatural, divine, or something else entirely. Monsignor Pruitt’s interpretation of the being as an angel reflects his deep faith—he cannot conceive of a supernatural explanation that doesn’t fit his religious framework. The creature’s apparent ability to heal and its dramatic effects on the island community support faith-based interpretations for the characters. For viewers, the question remains open, with the series suggesting that the line between horror and miracle depends largely on the observer’s worldview.

“The plot centers on a devout and impoverished island community that experiences supernatural events after the arrival of a mysterious priest” — Wikipedia, summarizing the series premise

Who plays the Mayor in Midnight Mass?

Michael Trucco plays Wade Scarborough, the mayor of Crockett Island, representing the island’s secular authority structure. As mayor, Wade must navigate the community’s growing religious fervor while managing the practical realities of a small, economically struggling island. His position puts him in direct tension with Bev Keane’s religious influence, particularly regarding decisions about the community’s response to the supernatural events unfolding around them.

Supporting cast roles

The Scarborough family forms a significant supporting ensemble in the series. Annarah Cymone plays Leeza Scarborough, Wade’s devout daughter who uses a wheelchair following an injury—her circumstances make her particularly receptive to the “miracles” that the creature appears to provide. Crystal Balint plays Dolly Scarborough, Wade’s wife and Leeza’s mother, occupying the difficult position of trying to hold her family together as the island’s social fabric strains under religious pressure.

The pattern across Wikipedia’s cast listings shows Flanagan populating Crockett Island with interconnected characters whose relationships create natural dramatic tension. The Scarboroughs’ position as the island’s political royalty contrasts with the Fly family’s complicated return, while the religious dimensions of characters like Leeza add another layer of meaning to the story’s central questions about faith and miracles.

Summary

Midnight Mass succeeds largely because Mike Flanagan cast actors capable of playing morally complex characters without easy categorization as heroes or villains. Kate Siegel brings Erin Greene to life as a woman caught between past love and present uncertainty, while Zach Gilford grounds Riley Flynn’s redemption arc in genuine human weight. Hamish Linklater shoulders perhaps the heaviest burden by playing both Father Paul and Monsignor Pruitt, often in the same scene. For viewers seeking their next Flanagan project or simply wanting to understand who plays whom on this critically acclaimed 2021 series, the cast pairings above provide a reliable reference from announcement through release.
