One Battle After Another is writer-director Paul Thomas Anderson's explosive 2025 action-thriller, released by Warner Bros. and loosely inspired by Thomas Pynchon's novel Vineland. It reunites Anderson with a sprawling ensemble and marks his first collaboration with Leonardo DiCaprio, anchoring what became the most expensive and widely seen film of the director's career.

DiCaprio plays Bob Ferguson, a burned-out former revolutionary living off the grid until his teenage daughter is abducted, forcing him to reconnect with his old radical comrades for a desperate rescue. Sean Penn is his menacing nemesis, a ruthless military officer, with Benicio del Toro, Regina Hall, Teyana Taylor, and newcomer Chase Infiniti rounding out the cast. Anderson stages the chase as both a propulsive thriller and a sly commentary on American paranoia and aging idealism.

The film drew some of the best reviews of Anderson's career and became his highest-grossing movie at the box office, before sweeping through awards season to win Best Picture at the Academy Awards. Praised for its formal daring, its performances, and its blend of suspense and dark comedy, it stands among the most acclaimed releases of the year. One Battle After Another is streaming on HBO Max.
