Javier Bardem and Florian Zeller Are Breaking Down Walls in ‘Bunker’
Money can buy a lot. A beautiful home, a comfortable lifestyle, and apparently, a luxurious underground bunker for when the world decides to call it quits. But can it buy happiness, security, or a marriage that hasn’t quietly fallen apart? That’s where things get a little complicated. In Bunker, acclaimed filmmaker Florian Zeller takes a premise that sounds like something ripped from a billionaire’s emergency-preparedness handbook and turns it into something far more personal. Starring Javier Bardem and Penélope Cruz, the film follows Miguel, a successful man whose opportunity to build an extravagant survival bunker for an extraordinarily wealthy client begins exposing cracks in his own seemingly comfortable existence.
What starts as an unusual business proposition becomes an examination of marriage, privilege, fear, and the increasingly elaborate ways people avoid confronting the world around them. And while the film features an actual underground refuge, Zeller is considerably more interested in the invisible ones we construct every day.
During an international press conference, Zeller and Bardem discussed the film’s emotional foundations, the experience of bringing the real-life married couple together onscreen, and the uncomfortable questions lurking beneath its provocative premise. The conversation offered plenty of thoughtful observations about modern society, along with a few laughs about marriage, parenting, and the advantages of working with someone who already knows all your habits. After all, when you’ve been married for nearly two decades, rehearsals might be the one production expense you can afford to cut.

Marriage, movies, and the art of not needing couples therapy
For Florian Zeller, Bunker began not with an underground fortress or an eccentric billionaire, but with a marriage. Having written the screenplay specifically for Javier Bardem and Penélope Cruz, the director wanted to explore what happens when two people who have built a life together gradually discover they may no longer be looking toward the same future. Relationships change, people evolve, and the person sleeping beside you may not be quite the same person you fell in love with years earlier.
The challenge, the director explained, is learning to stay connected while giving each other the freedom to grow. That emotional uncertainty became the foundation of Miguel’s relationship with his wife, a marriage that appears secure on the surface but has quietly developed some serious structural problems. Unfortunately, building an underground bunker won’t fix those.
For Bardem and Cruz, portraying a struggling marriage presented an interesting professional challenge. The two have shared the screen numerous times throughout their careers, but audiences inevitably bring an awareness of their real-life relationship to their performances. Bardem quickly distinguished the fictional couple from the real one. Their characters’ difficulties are not autobiographical, and the actors had no intention of turning the production into an elaborate exercise in marriage counseling.
Instead, they approached the material as professionals, drawing upon their familiarity with one another to create an authentic relationship without confusing their personal lives with the screenplay. That familiarity, however, came with some undeniable advantages. The actor joked that Zeller probably saved money on rehearsals because he and Cruz already understood each other’s rhythms so well. A look or subtle gesture could communicate an entire conversation without requiring lengthy preparation.
For Zeller, that instinctive connection was precisely what made the pairing so compelling. He praised the actors’ ability to express complicated emotions through silence, allowing the camera to capture what their characters couldn’t quite bring themselves to say. Of course, there was still the small matter of keeping work at work. Bardem emphasized that once filming ended, the couple returned to their everyday responsibilities as parents and partners. The fictional marriage could have its problems without bringing them home for dinner.
A billionaire’s bunker and the price of privilege
If the marriage provides Bunker with its heart, the billionaire’s extravagant survival project supplies its considerably darker sense of humor. Miguel is offered the opportunity to construct an elaborate underground refuge for a wealthy client determined to protect himself from an uncertain future. The assignment promises substantial financial rewards, but it also represents a dramatic departure from the work that once defined Miguel’s career.
As Javier Bardem explained, Miguel previously devoted himself to public projects, including libraries and hospitals. His professional accomplishments contributed to spaces designed for entire communities. Now, he’s being offered a lucrative opportunity to build something intended to benefit essentially one person. It’s quite a career pivot, especially when the new job carries an underlying message that everyone else is on their own.
Zeller, on the other hand, feels the billionaire’s bunker represents a contradiction he finds increasingly troubling. Some of the wealthiest and most influential people in the world have helped create technologies that connect society, yet possess the resources to withdraw from that same society when things become uncomfortable. The filmmaker sees that impulse reflected in everyday life, where technology lets people order food, watch entertainment, communicate with friends, and conduct business without ever leaving home.
Convenient? Absolutely. A little concerning when human interaction becomes an optional extra? Also absolutely. Florian Zeller suggested that these modern comforts can gradually create invisible barriers, encouraging people to see themselves as isolated individuals rather than members of a larger community. Miguel’s fascination with the billionaire’s world becomes particularly revealing because it forces him to confront the difference between personal success and social responsibility. The more appealing the promise of wealth and security becomes, the easier it is to overlook the people affected by his choices. And that, according to Bardem, is where the character’s moral dilemma becomes especially interesting.
Stephen Graham and the danger of judging a book by its cover
One of the film’s sharpest contrasts comes through a neighbor played by Stephen Graham, whose circumstances couldn’t be further removed from those of Miguel’s billionaire client. While one man can spend an extraordinary fortune preparing for a hypothetical catastrophe, Graham’s character is trying to convert a garage into a livable space just to keep a roof over his head. One is worried about surviving the end of civilization. The other is worried about surviving everyday life.
For Zeller, placing these two realities side by side exposes the growing divide between extraordinary wealth and ordinary economic insecurity. But the filmmaker takes the comparison further by challenging the audience’s assumptions about which character actually represents a threat. Graham’s character has tattoos, a working-class accent, and an appearance that Miguel interprets with suspicion. Zeller deliberately lets those impressions influence the audience, especially during a home invasion sequence that encourages viewers to question the neighbor’s intentions.
The resulting reversal is designed to make audiences reconsider how easily appearances, class, and unfamiliarity shape their judgments. Rather than simply delivering a narrative surprise, Zeller wanted viewers to recognize their own participation in those assumptions. Bardem connected the idea to a broader concern about how quickly people judge others without understanding their circumstances. He acknowledged having made those mistakes himself, emphasizing that genuine connection requires a willingness to listen and reconsider what we think we know.
In a world increasingly divided by wealth, ideology, and personal experience, that willingness can be surprisingly difficult to maintain. Sometimes the person we assume is dangerous is the one most willing to help. And sometimes the person with the most impressive bank account is the one building a very expensive hole in the ground.
When a painting says what a marriage cannot
Among the film’s more intimate elements is a painting depicting a couple sleeping together in the same bed, an image that carries particular emotional significance for Cruz’s character. Zeller explained that the artwork was central to his understanding of the story. Although the painting appears simple, it represents an intimacy that Miguel and his wife have gradually lost. When Sofia encounters the image, she responds emotionally without necessarily understanding why. It reminds her of something missing from her own relationship, something that has become increasingly difficult to articulate.
Miguel, meanwhile, struggles to understand her reaction. The disconnect is revealing. Two people can look at the same image and see entirely different things, just as they can share the same home, the same bed, and years of history while experiencing their relationship in completely different ways. Zeller drew inspiration from Homer’s The Odyssey, interpreting Miguel’s emotional journey as a modern variation on the struggle to return home.
Unlike Odysseus, Miguel hasn’t spent years traveling across distant seas. He’s been home all along. The problem is that emotionally, he’s wandered somewhere else entirely. His wife becomes a contemporary counterpart to Penelope, waiting not for his physical return but for the restoration of a connection that once seemed effortless. The artistic connection also extended behind the scenes. The creative revealed that the film’s gallery paintings were created by Spanish artist Agustí Puig, whose work previously appeared in Vicky Cristina Barcelona, another collaboration involving Bardem and Cruz.
For Bardem, the painting reinforced the importance of allowing art to affect us emotionally rather than demanding that everything be explained intellectually. Sometimes understanding a work isn’t about finding the correct interpretation. It’s about being willing to feel something. And for Miguel, that may be the most difficult lesson of all.
Javier Bardem shows his softer side
Audiences have certainly seen Bardem play intimidating characters. His screen presence can be commanding enough to make an otherwise ordinary conversation feel like a potentially life-threatening situation. Zeller, however, wanted something entirely different. When the filmmaker first met Bardem, he was struck by the actor’s gentleness, sensitivity, and emotional openness. Those qualities inspired him to create a character whose vulnerability would be as important as his authority.
Rather than relying on the imposing presence associated with some of Bardem’s most recognizable performances, Bunker asks him to explore uncertainty, emotional confusion, and the uncomfortable realization that a seemingly successful life may not be as fulfilling as it appears. Zeller praised Bardem’s ability to communicate those feelings through restrained expressions and gestures, finding considerable dramatic power in moments when the actor barely needed to speak.
Bardem returned the admiration, pointing to the compassion he sees throughout Zeller’s work, including The Father and The Son. Even when the filmmaker explores painful subjects, Bardem believes his stories remain deeply interested in understanding the people experiencing them. That sensitivity was a major reason he and Cruz were drawn to the project.
Bardem also spoke warmly about his wife’s artistry, reflecting on the creative intuition and adventurous spirit he has admired since they were young performers. Despite decades of accomplishments, he described Cruz as someone who continues to challenge herself and approach her work with remarkable curiosity. It was a particularly affectionate moment in a conversation largely devoted to the difficulties of marriage. Fortunately, the fictional couple’s problems don’t appear to have diminished his enthusiasm for his actual costar.
Parenting in the age of screens
The film’s exploration of disconnection isn’t limited to marriage or class. Miguel also struggles to communicate with his teenage daughter, whose relationship with technology creates another invisible barrier within the family. For Bardem, the subject hits close to home. Discussing his experiences as a father, the actor acknowledged that raising children in an increasingly digital world requires parents to learn an entirely new language, sometimes quite literally.
He joked about his own technological limitations, suggesting that even something as ordinary as sending an email can present a challenge. Unfortunately for parents, teenagers aren’t exactly waiting around for everyone else to catch up. Bardem expressed concern about how easily children can encounter troubling material online, noting the contradiction between the precautions parents take in the physical world and the comparatively unrestricted experiences available through a screen.
He explained that he and Cruz have approached technology cautiously with their children, trying to set boundaries while recognizing that digital culture is an unavoidable part of their lives. Zeller connected those concerns to a scene in which Miguel confronts his daughter about spending so much time absorbed in her phone and music. Rather than rejecting her father’s attempt to communicate, she invites him to listen to what she’s hearing. It’s a small gesture, but for the director, it captures something essential about the film. Miguel cannot expect his daughter to enter his world if he’s unwilling to make an effort to understand hers. The solution isn’t necessarily another rule, another argument, or another attempt to control the situation. Sometimes it’s simply sharing a pair of headphones.
A European production with a universal message
Although Bunker is set in London, Zeller explained that the film was shot in Madrid and produced in France, making it an international collaboration in both its production and storytelling. The film moves between English and Spanish, a creative choice that presented an interesting challenge for a director who doesn’t speak Spanish fluently.
Rather than viewing that limitation as an obstacle, Zeller found it liberating. Without understanding every word, he became more attentive to a scene’s emotional rhythms, focusing on expressions, gestures, and the subtle interactions between performers. Bardem praised that instinct, comparing the experience to working with Woody Allen on Vicky Cristina Barcelona, where the director could recognize the emotional effectiveness of Spanish-language performances without necessarily understanding every detail of the dialogue. For the director, the experience reinforced his belief that storytelling reaches beyond language. Love, disappointment, fear, and the desire to be understood are hardly exclusive to one country or culture. Neither, apparently, is the human ability to make relationships considerably more complicated than necessary.
Finding empathy in an exhausting world
As the conversation turned toward the film’s broader social implications, Javier Bardem reflected on the challenges of remaining emotionally engaged with a world filled with suffering, conflict, and uncertainty. The actor acknowledged that his professional success provides him with considerable privilege, including the ability to live comfortably and protect himself from many of the difficulties others face.
He described that privilege as a kind of personal bunker, one that could make it tempting to concentrate exclusively on his family, career, and immediate surroundings. But the actor believes staying connected to others’ experiences is essential, even when those experiences are difficult to confront. That doesn’t mean constantly absorbing distressing news without limits. He compared emotional engagement to physical training, pointing out that even dedicated athletes need time to recover. Compassion, he suggested, requires energy. Taking time to rest, spend time with loved ones, and regain perspective can help people stay engaged rather than become overwhelmed.
He also emphasized the importance of recognizing that people experience global events from dramatically different circumstances. Someone directly affected by violence or displacement faces challenges that cannot be equated with the emotional distress of watching those events unfold from a comfortable distance. For Bardem, empathy begins with acknowledging those differences rather than assuming everyone experiences the world in the same way.
The actor also addressed the relationship between his public advocacy and professional career, explaining that he remains grateful for his opportunities and continues to value working with people whose creative environments and principles he respects. Throughout the press conference, he returned to the same idea that drew him to Zeller’s screenplay: meaningful human connection requires the courage to look beyond our own experiences.
Bunker’s opening the door instead of building another wall
Despite its provocative premise, Zeller doesn’t want Bunker to feel like a lecture about wealth, technology, or the moral failings of modern society. Instead, he hopes audiences will recognize something of themselves in Miguel’s choices. Most people will never receive a lucrative offer to construct a billionaire’s underground survival fortress. But the temptation to prioritize comfort, security, or personal advancement over uncomfortable questions is considerably more familiar.
Zeller believes those everyday decisions reveal how easily people can retreat into their own interests while overlooking the consequences for others. The filmmaker also understands why isolation can seem appealing. With economic uncertainty, political conflict, and technological change making the future feel increasingly unpredictable, the desire to shut out the noise is hardly surprising.
But Bunker challenges the notion that withdrawing from the world offers any meaningful protection from it. Through Miguel’s marriage, his daughter, his neighbors, and his increasingly questionable professional ambitions, the film explores how fear can gradually replace curiosity, and how the pursuit of security can become another form of imprisonment. What makes Zeller’s approach intriguing is that the solution isn’t presented as some grand revelation. It begins with smaller, more human gestures: listening to someone we don’t understand, questioning an assumption, recognizing another person’s needs, or simply being willing to admit we’ve lost our way.
For Bardem, those ideas made the project an opportunity to explore a character whose greatest challenge isn’t surviving an external catastrophe, but confronting the emotional distance he’s created within his own life. And perhaps that’s the film’s most unsettling suggestion. We can spend enormous amounts of time, energy, and money preparing for everything that might go wrong tomorrow while completely overlooking what’s falling apart today. A bunker might keep the outside world out. But as Zeller and Bardem make clear, it can also keep us from getting out. And no amount of reinforced concrete will fix that.
