Krakatoa is a 2025 American semi-biographical disaster film directed by Roland Emmerich and based on the final twenty-four hours of the ancient Indonesian volcano Krakatoa before its famous eruption. The film stars Anne Hathaway as the fictional protagonist Gracie Boswell, Michiel Huisman as real-life Dutch geologist Rogier Verbeek, and John C. Reilly as the 21st President of the United States Chester A. Arthur. It is the first installment in the Chronicles of Gracie Boswell trilogy. The film follows Boswell, a biologist and adventurer, as she volunteers to investigate why Krakatoa is heavily active and seeks the advice of Verbeek while staying in Sertung Island to take notes. It also stars Alexandra Daddario, Joe Taslim, Jim Caviezel, Matt Nable, and Djimon Hounsou. Distributed entirely by Lionsgate and Angel Studios, Krakatoa premiered at the 82nd Venice International Film Festival on November 18th, 2025, and was released the following month. It was a massive blockbuster, grossing $981 million against its $250 million break-even point; the film received universal acclaim, mainly for its visually-appealing action sequences and Hathaway, Huisman and Reilly's performances, but criticized by some for its historical inaccuracies and portrayal of Krakatoa's first stage. Among its accolades, it received an Academy Award nomination for Best Adapted Screenplay and a Golden Globe Award for Best Original Film Score for Hans Zimmer. A sequel is in development.
