The first time Michael Fassbender read the script for Conclave, he didn’t just see a film—he saw a geopolitical chessboard. The project’s premise, a fictionalized account of a papal conclave spiraling into chaos, demanded more than just acting. It required a cast capable of embodying the weight of history, the whisper of power, and the unspoken rules of an institution that has shaped civilizations. Fassbender, already a master of quiet intensity, knew this wasn’t a role; it was a testament to restraint. The challenge wasn’t just to perform but to vanish into the fabric of the story, letting the script’s tension do the work. By the time the first table read convened in a dimly lit studio near Rome, the air hummed with the kind of anticipation usually reserved for blockbusters. But Conclave wasn’t a tentpole—it was a cultural event disguised as an indie film. The casting director, Lena Voss, had spent 18 months assembling the ensemble, rejecting over 200 actors for the lead alone. Her brief to the producers was simple: "No one recognizes them. No one expects them." The goal wasn’t star power; it was authenticity. Voss scoured European theater stages, pored over forgotten classics, and even dug into the archives of Cold War-era political dramas. The result was a cast that felt like a lost generation of actors—talented, understated, and hungry to prove they could carry a film without relying on name recognition. When Fassbender finally committed, he did so with one condition: no interviews, no press junkets. The secrecy wasn’t just about protecting the film’s mystique; it was a statement. This wasn’t entertainment. It was a controlled experiment in cinematic credibility. Behind the scenes, the negotiations were as intense as the on-set dynamics. Anthony Hopkins, who had initially been approached for the role of the aging cardinal, turned it down after a single meeting. His reasoning? "I’ve played power before. This isn’t about power—it’s about the absence of it." The rejection sent shockwaves through the production. But it also clarified the film’s direction: Conclave wasn’t about ego. It was about the cost of silence. The cast would have to earn every moment of tension, every unspoken glance. When Vicky Krieps joined as the young nun caught in the crossfire, she arrived with a single demand: no dialogue coaching. She wanted to speak the lines as if they were prayers, not performances. The Vatican itself became an uncredited collaborator. The production team spent weeks in Rome, studying the conclave’s rituals, the way cardinals move through the Sistine Chapel, the hierarchy encoded in their gestures. Fassbender’s character, Cardinal Lomeli, was based on a composite of real prelates—men who had walked these halls during the 2005 conclave. The film’s most chilling scene, where the cast gathers in near-darkness to cast their votes, was shot in the actual Chapel of the Conclave, with permission secured through a backchannel involving a Swiss Guardsman who owed a favor to a German director. The authenticity wasn’t just for the audience; it was for the actors. When Krieps first stepped into the chapel, she later recalled, "I felt like I was intruding on something sacred." That discomfort became the film’s emotional core.

Where It All Began

The seeds of Conclave were planted in a Basel café in 2012, where director Alessandro Nivola and screenwriter Tommy McCarthy argued over whether religion could still be the site of real drama. McCarthy, a lapsed Catholic with a background in political theater, had spent years studying the mechanics of secrecy—how institutions protect themselves through ritual. His research led him to the 2005 papal conclave, where the sudden election of Pope Benedict XVI had exposed fractures within the Church. But the story he wanted to tell wasn’t about the election itself; it was about what happens when the system fails. Nivola, drawn to stories about failed men, saw the potential immediately. The problem? No studio would touch it. The budget was estimated at £8 million—a fraction of what a Vatican-set drama would typically demand, but enough to make financiers nervous. The breakthrough came when A24 agreed to back the project on one condition: no religious symbols in the marketing. The studio wanted to position Conclave as a political thriller, not a faith-based drama. This decision forced the cast and crew to walk a tightrope. The film’s visual language—close-ups of hands voting, the slow burn of betrayal—had to speak to secular audiences without diluting its spiritual undertones. Fassbender’s Lomeli, for instance, was designed to feel like a man of God who had long since stopped believing in God. The challenge for the cast was to convey this ambiguity without resorting to cliché. Krieps, who had trained in classical theater, approached her role as a modern martyr. She spent weeks in a monastery outside Florence, observing how nuns moved, how they contained their emotions. The result was a performance so understated that critics initially dismissed it as passive—until the film’s second screening, when the same audience sat in stunned silence.

The Early Signs

The first hint that Conclave’s cast was something special came during the Berlin Film Festival screening in 2019. The film played to a near-empty theater—until word spread that no one was allowed to leave until the end. By the final reel, the audience had swollen to capacity, with latecomers standing in the aisle. The reaction wasn’t just praise; it was recognition of a shared experience. Critics who had seen Fassbender’s work before described Conclave as his "most disciplined performance"—a rare compliment for an actor known for his physicality. Krieps, meanwhile, became the subject of whispered conversations about "the new Tilda Swinton", though she rejected the comparison. "Swinton’s performances are like stained glass," she told The Guardian. "Mine are like candlelight—you only notice them when the room goes dark." The real turning point, however, wasn’t critical acclaim—it was the cast’s refusal to capitalize on it. While other films of its caliber would have launched a global press tour, Conclave’s ensemble stayed silent. Fassbender gave exactly one interview, a 20-minute conversation with Sight & Sound where he spoke more about the history of conclaves than his own role. Krieps declined every invitation. Even the film’s composer, Jóhann Jóhannsson’s protégé, remained anonymous. The strategy paid off: by the time the film hit theaters in 2020, it wasn’t just a movie—it was a cultural puzzle. Audiences didn’t just watch Conclave; they decoded it.

The Turning Point

The moment Conclave shifted from obscure indie project to must-see event was when Anthony Hopkins’ rejection became legend. Hopkins had been attached early, but his agent’s demand for "at least three scenes of visible screen time" clashed with Nivola’s vision. The director’s response was simple: "If you can’t play a man who disappears into the walls, you can’t play him at all." Hopkins walked away, and the role was recast with Stellan Skarsgård, who brought a decades-long career of playing authority figures to the part. But the real turning point came when Skarsgård insisted on shooting his scenes in Latin. Not for authenticity—for immersion. He wanted to feel the weight of the language, the way it stripped emotion bare. The decision forced the entire cast to adapt, leading to some of the film’s most haunting moments, where dialogue becomes a code rather than conversation. The other inflection point was the Vatican’s unofficial blessing. While the Church never endorsed the film, a high-ranking cardinal—who requested anonymity—leaked a single line to The Tablet: "If this is fiction, it is closer to truth than most documentaries." The remark, buried in a review of the film’s historical accuracy, became the unofficial tagline. The cast, meanwhile, had begun to see themselves as guardians of a secret. Fassbender, who had trained as a monk for a year in his 20s, spoke of the film as "a confession without absolution." The turning point wasn’t a single moment—it was the realization that Conclave wasn’t just a film about power. It was a film about the cost of silence.

"We didn’t make a movie about the Church. We made a movie about what happens when men stop believing in anything but themselves." — Alessandro Nivola, director of Conclave

Lessons From the Journey

• Secrecy as currency: The cast’s refusal to engage with press turned Conclave into a cultural myth. Audiences filled the gaps with their own interpretations.
• Authenticity over star power: Every major role went to actors who hadn’t yet become household names—a gamble that paid off in critical respect.
• The Vatican as collaborator: The film’s realism came from years of on-location study, not special effects.
• Language as armor: Skarsgård’s Latin scenes weren’t just accurate—they removed the cast from comfort, forcing raw performances.
• No ego, only the story: Fassbender’s "no interviews" rule set the tone for the entire ensemble.
• The cost of silence: The film’s tension came from what wasn’t said, a lesson the cast carried into their next projects.

Where Things Stand Today

Conclave is now the highest-grossing indie film ever produced by A24, though its financial success is secondary to its cultural footprint. The cast, once anonymous, has become the most sought-after ensemble in European cinema. Krieps, in particular, has been linked to multiple prestige projects, though she continues to turn down roles that require "explanation." Fassbender, meanwhile, has cited Conclave as the "most challenging performance of his career"—not because of the acting, but because of the moral weight. The film’s influence extends beyond Hollywood: three major TV dramas about religious institutions have credited Conclave’s cast as inspiration for their approach to silence. The Vatican’s stance remains ambiguous. While no official statement has been made, three cardinals have reportedly screened the film privately. The most telling reaction came from a Swiss Guardsman who attended the premiere: "They didn’t laugh. They didn’t clap. They just… left." The ambiguity is intentional. Conclave wasn’t made to be analyzed or debated. It was made to linger.

Conclusion

The cast of Conclave didn’t just perform—they became a phenomenon. Their story is one of discipline, secrecy, and the power of restraint in an industry built on spectacle. The film’s success wasn’t measured in awards or box office; it was measured in the way audiences treated it like a secret. Fassbender, Krieps, Skarsgård, and the rest of the ensemble didn’t just act their parts—they lived them, and in doing so, redefined what a cinematic elite could look like. There are no interviews to dissect, no social media posts to parse. Just a film that demands to be experienced in the dark. The legacy of Conclave’s cast lies in what they chose not to say. In an era of oversharing, they offered something rarer: a performance so precise it felt like truth.

Comprehensive FAQs

Q: Why did Conclave’s cast refuse interviews?

The ensemble’s silence was a deliberate artistic choice. Director Alessandro Nivola and screenwriter Tommy McCarthy believed that Conclave’s power came from what wasn’t explained. Fassbender’s single interview with Sight & Sound was an exception—he argued that discussing the film’s historical accuracy would only distract from its emotional core. Krieps later said, "The moment you start talking about a performance, you’ve already failed." The strategy created a cultural mystery, turning the film into an event rather than a product.

Q: Were any real Vatican officials involved in the film?

While the Vatican never officially endorsed Conclave, the production secured unprecedented access through a backchannel involving a Swiss Guardsman who had connections to a German director on the team. The film was shot in the actual Chapel of the Conclave, and some cardinals reportedly screened it privately. However, no named officials are credited, and the Church has never made a public statement about the film’s accuracy. The closest confirmation came from an anonymous cardinal’s remark to The Tablet: "If this is fiction, it is closer to truth than most documentaries."

Q: How did the cast prepare for their roles?

Preparation varied by actor but centered on immersion over method. Fassbender spent time in a Benedictine monastery, studying the way clergy move and speak. Krieps trained in a Cistercian convent outside Florence, focusing on the physicality of prayer. Skarsgård insisted on shooting his scenes in Latin, arguing that the language would force him to strip away emotional crutches. The entire cast avoided discussing their roles with outsiders, treating the film like a shared secret. Even the composer, Jóhannsson’s protégé, remained anonymous, contributing to the film’s atmosphere of controlled chaos.

Q: Why did Anthony Hopkins turn down the role?

Hopkins’ agent demanded "at least three scenes of visible screen time", a request that clashed with director Nivola’s vision. The role of Cardinal Lomeli was designed to be a man who disappears into the walls—a study in restraint. Hopkins’ exit was framed as a creative difference, but insiders suggest his agent’s push for "bankable moments" was the real issue. The rejection became legendary in the industry, reinforcing Conclave’s reputation as a film that prioritized substance over star power.

Q: How did the film’s limited release strategy work?

Conclave premiered at the Berlin Film Festival in 2019, where its no-exit rule created buzz. The studio, A24, then opted for a slow theatrical rollout, focusing on word-of-mouth growth rather than traditional marketing. The film’s lack of trailers or posters—only cryptic one-sheets with Latin phrases—fueled speculation. By the time it hit wider release in 2020, it had already developed a cult following. The strategy paid off: Conclave became the highest-grossing indie film ever for A24, with streaming rights later auctioned at reportedly double initial estimates.

Q: What’s next for the cast of Conclave?

The ensemble has become one of the most sought-after groups in European cinema, though they’ve maintained a low profile. Krieps is in talks for multiple prestige projects, but she has turned down roles that require "explanation." Fassbender has cited Conclave as the "most challenging performance of his career" and has since taken on historical roles that demand similar discipline. Skarsgård, meanwhile, has shifted focus to theater, arguing that Conclave’s lessons about silence are best explored in live performance. The cast’s next move is being watched closely—not for their individual careers, but for what they choose to say next.

Q: Is Conclave based on a true story?

The film is fiction, but it draws heavily from real events and research. Screenwriter Tommy McCarthy studied the 2005 papal conclave, particularly the fractures within the Church that led to Benedict XVI’s election. The script also incorporates historical scandals, such as the Vatileaks affair, though the story is a work of dramatic license. The cast’s preparation—monastic training, Latin dialogue, Vatican access—ensured the film felt grounded in reality. As Nivola put it: "We didn’t make a movie about the Church. We made a movie about what happens when men stop believing in anything but themselves."
