Oscar winners Javier Bardem (No Country for Old Men) and Penélope Cruz (Vicky Cristina Barcelona) will star in psychological thriller, Bunker.

In Bunker, when an architect accepts a morally ambiguous project — building a survivalist bunker for a tech billionaire — his wife begins to question their marriage after 17 years together. The film is described as “a thriller that delves into the emotional and moral challenges a couple faces amid the tensions of the world around them, exploring the fears, doubts, and dilemmas that define our era”.

Bunker is written and directed by Florian Zeller (The Father), who specifically wrote the film for Bardem and Cruz, who are a real-life couple.

Blue Morning Pictures’ Federica Sainte-Rose is set to produce alongside Fernando Bovaira and Simon de Santiago of MOD Producciones. Alice Dawson will also serve as a producer on the film. Mariano Cohn, Gaston Duprat, Andres Duprat, Emanuel Nunez and Fernando Sokolowicz will executive-produce.
