Paul Dano — known for channeling quiet menace in The Batman — has officially joined the cast of the psychological thriller Bunker, the latest nightmare from Oscar-winning filmmaker Florian Zeller (The Father).

Dano joins an already stacked lineup including Javier Bardem, Penélope Cruz, Stephen Graham, and Patrick Schwarzenegger, setting the stage for a tense, performances-driven descent into paranoia.

Currently in production, Bunker follows a family slowly unraveling as a mysterious underground structure — commissioned by a powerful tech mogul — begins to poison their lives. What starts as a construction project becomes an invasive presence, warping relationships and sanity as its true purpose creeps into focus.

Zeller, who writes and directs, promises a thriller steeped in emotional brutality and suffocating atmosphere. “We are thrilled to welcome Paul Dano to the cast,” he said. “From Little Miss Sunshine to There Will Be Blood, Paul has always brought something singular and irreplaceable.”

The praise lands in the wake of Quentin Tarantino’s recent digs at the actor — a contrast that only highlights Dano’s cult-favorite status among fans of twisted, character-driven cinema.

Filming is underway now. Expect more unsettling updates from Bunker as this psychological pressure cooker continues to take shape.
