Hollywood celebrities live their lives in the spotlight, but some stars have connections that go far beyond the usual red carpet gossip. Over the years, a number of well-known actors have been linked to controversial religious groups and organizations that critics have described as cults.
These stories raise real questions about influence, belief, and personal freedom. From longtime members to those who managed to escape, here is a look at 12 famous faces tied to some of the most talked-about groups in recent history.
1. Tom Cruise
Few celebrity-organization relationships have attracted more media attention than Tom Cruise’s decades-long connection to the Church of Scientology. Cruise joined the church in the 1980s and quickly became its most recognizable public face.
His enthusiastic support has sparked countless headlines over the years.
Critics of Scientology have raised concerns about the group’s practices, including allegations of controlling behavior and financial demands on members. Cruise has consistently defended the church, calling it a positive force in his life and career.
Despite ongoing controversy, he has never publicly wavered in his commitment. His high-profile status has arguably helped Scientology maintain cultural visibility.
Whether you view his loyalty as inspiring or puzzling, there is no denying that Tom Cruise and Scientology have become one of the most talked-about celebrity-organization pairings in Hollywood history.
2. John Travolta
Long before Scientology became a household word, John Travolta was already one of its most devoted celebrity followers. He joined the church in the mid-1970s, crediting it with helping him navigate the pressures of early fame.
His loyalty has remained steady through decades of personal and professional changes.
Travolta has spoken warmly about how Scientology shaped his outlook on life and relationships. Critics, however, point to troubling claims made by former church members about pressure tactics and secrecy within the organization.
His connection to the church has occasionally created friction with journalists and interviewers, who often press him on the subject. Travolta typically deflects with grace, staying positive and brief.
Regardless of public opinion, his five-decade membership makes him one of Scientology’s longest-standing celebrity representatives and a consistent symbol of the church’s Hollywood influence.
3. Elisabeth Moss
There is something undeniably ironic about Elisabeth Moss, star of The Handmaid’s Tale, being a practicing Scientologist. The show depicts a dystopian society built on control and religious extremism, themes that critics frequently point to when discussing Scientology itself.
Moss has acknowledged the irony but continues to defend her faith.
Raised in the church from childhood, Moss has described Scientology as a personal and spiritual foundation. She rarely goes into detail publicly, but when pressed, she stands firm in her support.
Former Scientology members have spoken out about experiences they found harmful, adding layers of complexity to how the public views her association. Moss is widely respected for her acting talent, and many fans find her connection to the church surprising.
Her story highlights how deeply personal belief systems can be, even when they draw public scrutiny.
4. Kirstie Alley
Kirstie Alley never shied away from talking about her faith. Before her passing in December 2022, she was arguably Scientology’s most outspoken celebrity champion, defending the church loudly and publicly across social media and interviews.
Her passion for the organization was unmistakable.
Alley credited Scientology with helping her overcome drug addiction early in her career, a claim she repeated often. She also pushed back strongly against critics and former members who spoke negatively about the church, sometimes engaging in heated public debates.
Her willingness to engage made her a unique figure in the Scientology conversation. While many celebrity members stay quiet, Alley leaned in.
Fans who loved her for roles in Cheers and Look Who’s Talking sometimes struggled to reconcile her warm on-screen persona with her fierce organizational loyalty. She remained committed to the church right up until her death.
5. Danny Masterson
Danny Masterson’s name became synonymous with controversy after multiple women accused him of sexual assault. His subsequent trial and 2023 conviction on rape charges sent shockwaves through Hollywood.
Throughout the legal proceedings, his ties to Scientology attracted significant attention from journalists and advocates.
Several accusers claimed that church officials discouraged them from going to police, using internal dispute resolution practices instead. The Church of Scientology denied any wrongdoing or interference in the criminal case.
Masterson, best known for playing Hyde on That ’70s Show, maintained his innocence throughout the trial. His conviction drew renewed scrutiny to how the church handles allegations made against members.
Advocacy groups used the case to highlight concerns about organizations that manage internal disputes in ways that may discourage outside legal intervention. The case remains one of the most high-profile intersections of celebrity, religion, and criminal justice in recent memory.
6. Allison Mack
Allison Mack’s fall from beloved TV actress to federal defendant shocked fans who knew her from Smallville. She became a high-ranking member of NXIVM, an organization that federal prosecutors described as a cult that recruited and exploited women.
Her role within the group went far beyond simple membership.
Mack served as a key recruiter for a secretive subgroup called DOS, in which women were reportedly branded and coerced into servitude. In 2019, she pleaded guilty to racketeering conspiracy charges, cooperating with prosecutors in the case against NXIVM founder Keith Raniere.
She was sentenced to three years in prison in 2021. Her transformation from a fan-favorite actress to a central figure in a criminal organization remains one of Hollywood’s most disturbing stories.
Mack has expressed remorse publicly, acknowledging the harm caused to those she recruited into the group.
7. Nicki Clyne
Most fans remember Nicki Clyne for her role as Cally Henderson on Battlestar Galactica, but her post-acting life took a deeply controversial turn. Clyne became one of NXIVM’s most visible defenders, standing by founder Keith Raniere even after his 2019 conviction on sex trafficking and racketeering charges.
She was reportedly among the inner circle of the DOS subgroup and was seen outside the courthouse during Raniere’s trial, holding demonstrations of support. Clyne married Allison Mack, reportedly at Raniere’s suggestion, which some saw as an attempt to help Mack avoid deportation to Canada.
Unlike many NXIVM members who distanced themselves from the organization after its criminal exposure, Clyne maintained a public stance of loyalty. Her story raises questions about how deeply ideological influence can shape a person’s judgment, even in the face of overwhelming legal and public evidence against a group’s leadership.
8. Catherine Oxenberg
Catherine Oxenberg never joined NXIVM herself, but her connection to the organization became intensely personal when her daughter India became deeply involved. Rather than staying silent, Oxenberg launched a very public campaign to expose the group and rescue her daughter, becoming one of NXIVM’s most effective critics.
She spoke to media outlets, worked with law enforcement, and eventually wrote a book titled Captive about her experience. Her advocacy helped bring wider public attention to NXIVM’s practices at a critical moment in the investigation.
Known for her role on Dynasty, Oxenberg used her celebrity platform in a way that many believe contributed to the eventual prosecution of Keith Raniere. Her story is often described as a mother’s love overcoming fear and institutional pressure.
She has since become an advocate for cult awareness and education, helping others recognize warning signs in high-control groups.
9. India Oxenberg
Growing up with a famous mother gave India Oxenberg access to a glamorous world, but it also made her a target for NXIVM recruiters. She joined the organization as a young adult, eventually becoming a member of the secretive DOS subgroup.
Her experience inside the group was later described in documentaries and interviews as deeply manipulative and psychologically damaging.
India was among the women who were reportedly branded and subjected to strict behavioral controls. After her mother’s relentless public campaign, she eventually left the group and cooperated with federal investigators.
She appeared in the documentary series The Vow and has spoken candidly about how she was gradually drawn deeper into the organization. Her story is a powerful reminder of how intelligent, capable people can find themselves trapped in high-control environments.
India has since used her platform to educate others about the psychological tactics used by manipulative groups.
10. Joaquin Phoenix
Joaquin Phoenix carries a childhood unlike almost any other Hollywood star. He spent his early years traveling with his family as members of the Children of God, a religious group founded in the late 1960s that has faced serious allegations of abuse, including the sexual abuse of minors.
The family eventually left the group.
Phoenix has rarely discussed the experience in depth, but it clearly shaped his complex, unconventional path through life and art. His family, including siblings River, Rain, and Summer Phoenix, all emerged from that background to pursue careers in entertainment.
The Children of God, later rebranded as The Family International, has been the subject of numerous investigations and lawsuits around the world. Phoenix’s early exposure to such an environment adds a fascinating and sobering layer to understanding one of Hollywood’s most intense and committed performers.
His story is a testament to resilience.
11. Rose McGowan
Rose McGowan did not just grow up near a controversial organization. She was born into one.
Her early childhood was spent within the Children of God movement, a group that critics and former members have accused of widespread abuse and extreme isolation from mainstream society. Her family eventually fled to escape the group’s control.
McGowan has spoken openly about the impact of that upbringing, describing the experience as formative in both damaging and illuminating ways. Her later advocacy work, particularly around the MeToo movement, has been seen by many as connected to a lifelong pattern of challenging powerful institutions.
Her story drew renewed attention to the Children of God and the lasting trauma that high-control religious environments can inflict on children. McGowan’s willingness to speak publicly about difficult personal history has made her one of Hollywood’s more courageous and complicated public voices on issues of power and exploitation.
12. Glenn Close
Glenn Close is one of Hollywood’s most decorated actresses, but she carries a chapter of her past that few fans know about. From age seven to twenty-two, she lived within Moral Re-Armament, a movement founded in the 1930s that promoted absolute moral standards and tight community living.
Close has described the experience as isolating and psychologically controlling.
In interviews, she has explained that the group discouraged independent thinking and kept members cut off from the outside world. She has used the word cult to describe how it felt, and she credits her eventual departure as a turning point toward personal freedom.
Her years in the group left a lasting impression on how she approaches characters dealing with control, repression, and emotional constraint. Close has spoken about the experience with thoughtfulness and honesty, helping raise awareness about how high-control groups can affect people across all backgrounds and social classes.
