Cassandra Cain (titled on-screen and on the posters as Gotham Origins: Cassandra Cain) is a 2026 American superhero film based on the DC Comics character of the same name. Produced by DC Studios, Legendary Pictures, and The Stone Quarry and distributed by Warner Bros. Pictures and Lionsgate Films, it is the first installment in the DC Cold Blood Universe. The film is directed by Cary Joji Fukunaga from a screenplay by James Gunn and Peter Safran, and stars Rina Sawayama as the title character alongside Michelle Yeoh, Ed Skrein, Sam Neill, Antonio Banderas, Florence Pugh, Wesley Snipes, Alexander Ludwig, Gerard Butler, and Jon Hamm. In the film, Cassandra has a strained relationship with her parents and abandons the League of Assassins, which sets her on a path to become an unconventionally heroic vigilante in Gotham City. Along the way, she is pursued by the Justice League, who wants her to join them. Cassandra Cain premiered at the 83rd Venice International Film Festival on October 17th, 2026, and was released theatrically on November 1st. The film was a critical and commercial success, grossing $716 million at the worldwide box-office. Critics and audiences particularly praised the story, reimagining, visual effects, action, Sawayama's performance, and faithfulness to the comics, but several critics were divided on its extreme violence, the overly dark tone, and the decision to give the film an R-rating. A sequel is in development.
