Bunker Trailer Puts Bardem and Cruz in a Survivalist Marriage Spiral

Sony Pictures Classics released the first official Bunker trailer this week, and the footage wastes no time. The psychological thriller stars real-life couple Javier Bardem and Penélope Cruz as Miguel and Sofia, a married couple whose relationship starts cracking when Miguel accepts a commission to design an underground survival bunker for a tech billionaire. Paul Dano plays the billionaire. Stephen Graham plays the neighbor. The Bunker trailer stays tense from its opening seconds, and it positions the film as one of awards season's sharpest thrillers.

The premise is simple and unsettling. Miguel Moreno, played by Bardem, is a successful London-based Spanish architect. Andrew, played by Dano, is a paranoid tech billionaire who hires Miguel to build an elaborate doomsday bunker. As the project pulls Miguel deeper into a world of extreme wealth, Sofia starts questioning a marriage the two have held together for seventeen years, along with her husband's changing values. ComingSoon, which covered the trailer release, describes the atmosphere as one of creeping dread, paranoia, and moral compromise.

What the Bunker trailer actually shows

The trailer opens with the commission itself: a lucrative offer to design a survival structure for an eccentric billionaire. Miguel accepts. Sofia grows uneasy. The trailer examines the marriage more than the construction, and the dread tightens when Toby, played by Graham, starts intruding in ways the footage leaves deliberately unclear. Patrick Schwarzenegger also appears as Jeremy, though the trailer keeps his role close to the vest.

What makes the footage land is how ordinary the horror looks. There are no explosions, just conversations between a husband and wife getting colder while a fortune gets spent on a hole in the ground. It works because the fear underneath it is recognizable: money changing someone you thought you knew.

There is also a reason the Bunker trailer is connecting right now. The ultra-rich building private bunkers has become a real-world talking point, and Zeller's film turns that anxiety into a class satire: the billionaire buys safety, the architect sells his conscience to design it, and the marriage pays the difference. It is the same unease that made doomsday-prepping documentaries and survivalist TikToks take off, only aimed back at the people writing the checks.

Bardem and Cruz, back on screen together

Bardem and Cruz have shared the screen before, in Jamón Jamón, Vicky Cristina Barcelona, The Counselor, and Loving Pablo. Bunker puts them back in the same frame as husband and wife, with their characters' seventeen-year relationship echoing the actors' own long partnership off screen, according to ToyPeople's coverage of the film.

The film is written and directed by Florian Zeller, the filmmaker behind The Father, which won Zeller and Anthony Hopkins Oscars for its portrait of a man living with Alzheimer's. ToyPeople notes that Bunker takes inspiration from the 2010 Argentine film The Man Next Door, about an architect tormented by his neighbor. Zeller built his reputation on hushed family dramas, and the Bunker trailer suggests he has carried that domestic unease into something more menacing.

Venice applause and a December release

Bunker had its world premiere in the main competition of the 83rd Venice International Film Festival, where it competed for the Golden Lion. It has since screened in Toronto, Zurich, and London. ComingSoon reported that the Venice premiere earned a standing ovation lasting sixteen minutes and thirty seconds, the longest of the festival up to that point.

The release plan is a clear awards-season play. Sony Pictures Classics will open Bunker in a limited run on December 11, 2026, then expand nationwide on January 15, 2027, as The Playlist reported. The Bunker trailer arrives right on schedule for that campaign: a tense, starry preview built to land the film on year-end lists.

The Bunker trailer is the latest in a busy stretch for trailer drops. We recently covered A24's The Debut trailer pitting Moore against Giamatti, and Kai Cenat's Japan return trailer topping YouTube's charts. And for a reminder that not every viral clip is what it claims to be, there is the AI interview video that fooled the internet.

You can read ComingSoon's full breakdown of the footage, and The Playlist's take on the teaser. For now, the trailer does exactly what a good one should: it tells you the setup, hides the payoff, and leaves you uneasy about everyone on screen.
