TIFF 2026: ‘Bunker’ (2026) Plays Things Safe Despite Its Onscreen Magnetism

The lure of power couple Javier Bardem and Penélope Cruz is undeniable in writer/director Florian Zeller‘s Bunker (2026). That chemistry is one of the few things that will keep people rooted in this otherwise middling psychological thriller about a couple’s mutual midlife epiphany. With a fairly predictable three-act structure, save for the final hour burst of fight-or-flight-level stakes, this is arguably Zeller at his safest. This isn’t necessarily a bad thing, but his previous efforts prove that he is capable of pushing more than he manages here. 

In the opening scene, Zeller lays the groundwork for the cracking marriage. A story of first-time love, recalled by the award-winning architect Miguel (Javier Bardem), quickly turns subtly sour when Miguel reveals to his dinner guests the truth behind the tears he shed on his first date with his wife of 17 years, Sofia (Penélope Cruz). Close-up shots of their faces, with the lens flipping back and forth between them, show how the story affects each of them; for Sofia, it’s like a cold glass of water thrown in her face. 

Not long after, Miguel is courted by an unnamed billionaire to construct a luxury bunker, a project that sparks a heated conversation between husband and wife. Any subtext Zeller might have intended gets tossed out the window, with the growing divide between rich and poor a constant reminder throughout Bunker (2026). Whether it’s the walls Miguel has built after uprooting his family, or the literal breaking down of the wall between Miguel and his less affluent neighbor (Stephen Graham), it shows how thinly connected they really are.

Bunker (2026) is arguably Florian Zeller’s safest film, despite it dwelling in thriller territory.

There’s some humor here, with a Paul Dano cameo conjuring images of a more approachable Mark Zuckerberg or Elon Musk-type. Of course, his inclusion represents a more damning difference between Miguel and himself. Dano’s tycoon thinks he can buy Miguel with enough money. And for a brief moment, Miguel almost is. The thing is, anything can happen, and with a marriage walking a tightrope into uncertainty, whether Miguel actually succumbs to greed is up in the air until the film’s resolution.

As the architect, Bardem fills the role with a familiar energy. Everything should be smooth sailing after his Miguel wins this award, but it’s not; tiny things start chipping away at the typically in-control Miguel, allowing Bardem to play with a concoction of confusion, exasperation, and futility as he’s left grasping at straws. While the role itself doesn’t stretch the full breadth of his range, Bardem hits a stride that is all his own.

And, of course, the chemistry between him and Cruz is naturally magnetic, aided by their years of marriage in real life. Yet, of the two characters, it’s Cruz’s Sofia that is arguably more fascinating. She’s at an impasse in her own career, with thinly disguised xenophobia preventing her from scaling any further up the career ladder in London. The weight of sacrifice and lost potential weighs heavily, and while Sofia can’t share her true feelings with her husband, Cruz exquisitely reflects every moment of uncertainty and inner turmoil on her face. 

While its central couple is enough to keep one invested, the supporting cast falls by the wayside.

The slow-brewing conflict between husband and wife is arguably enough to drive Bunker (2026), and for the most part, it does. The side plots in their separate lives, complete with supporting characters, are less fulfilling. Patrick Schwarzenegger‘s emerging author is forgettable, both on paper and in performance. When he espouses sage wisdom from his fiction in a discussion with Sofia, the line reading falls flat, making the kindred energy meant to be shared between them unbelievable. 

Graham’s Toby fares better, in part, due to Graham’s ability to convey a lot with very little. His character is more symbolic than anything else, and from the styling to the affectation Graham puts on, he conveys the working-class sensibility Miguel is progressively trying to distance himself from. While the conflict between the two doesn’t fully fit into the grander scheme, you can still see what Zeller was trying to accomplish, albeit clumsily.  

Alain Bainée’s production design plays a huge part in the more successful visual theming around isolation and false safety in Bunker (2026). Even with its more open living room and dining space, the home almost functions like a cage, where the family themselves are on display (an element that becomes key later in the film). A feature that both creates a sense of safety and heightens the feeling of being watched. 

The visual and auditory design in the film punctuates its theming and tone.

Jorge Adrados’s sound design draws out tension from the very beginning. Loud bangs and discordant tones punctuate the unease between Miguel and Sofia early on. Paired with Volker Bertelmann’s score, it blends to do the heavy lifting of inducing thrills and anxiety where the screenplay fumbles. It’s not for lack of trying, however, in the third act, with a dramatic, violent incident meant to marry the many ideas Zeller has been toying with.

Unfortunately, it doesn’t quite deliver the expected results, nor does the final shot of Bunker (2026) feel entirely earned (despite the full-circle moment it evokes in the end). Some pruning in the plot might have finessed these final moments and brought them clarity. The decision to cut to black in a pivotal moment right when tensions were the highest offers little respite; instead, Zeller chooses the safer option rather than pushing things farther. There was certainly room to do so. 

Bunker (2026) makes it clear that Florian Zeller has many things he wanted to explore and discuss here, but never quite gets to a point where he can dive deeper than surface-level manifestations. These are relevant topics to cover, of course, but the film never fully explores them. What keeps Bunker (2026) suspenseful, intriguing, and engaging is how damn good Javier Bardem and Penélope Cruz are at their craft. In less capable hands and with less in-your-face charisma and magnetism, the film would be all the weaker without them.

Bunker (2026) played as part of the 2026 Toronto International Film Festival. The film will release in theaters in select cities this December 11, 2026, before opening in US theaters nationwide January 15, 2027.
