Exciting News: The War of the Roses Returns in 2025 with Major Film, Book, and Stage Events We’re thrilled to announce that The War of the Roses is making a triumphant return to center stage—across film, books, and theater—cementing Warren Adler’s classic dark comedy as a timeless cultural touchstone. Searchlight Pictures’ new feature film adaptation, The Roses, the first  of a first-look deal between AET and Searchlight is set for worldwide theatrical release on August 29, 2025. Directed by Jay Roach and written by Oscar-nominated screenwriter Tony McNamara (The Favourite, Poor Things), this reimagining stars Oscar-winners Olivia Colman and Benedict Cumberbatch as Ivy and Theo Rose, a seemingly perfect power couple whose marriage spectacularly unravels in the most deliciously diabolical way. The all-star cast also includes Kate McKinnon, Andy Samberg, Allison Janney, Ncuti Gatwa, Jamie Demetriou, Zoë Chao, and Belinda Bromilow. To celebrate the release, the original novel The War of the Roses will be re-published worldwide in summer 2025 with an all-new cover. This new edition offers a chance for longtime fans and new readers alike to experience the brilliant, biting satire that started it all. And the excitement doesn’t end there… Coming to London’s West End in 2026, The War of the Roses will hit the stage in a thrilling new adaptation by acclaimed writer and producer Peter Tolan. Known for his sharp wit and keen understanding of complex relationships, Tolan’s major credits include Rescue Me (co-creator with Denis Leary), The Larry Sanders Show, and Analyze This. His adaptation promises to bring Warren Adler’s explosive portrait of marital warfare to life with all the dark humor, pathos, and emotional fireworks that have captivated audiences for decades. Stay tuned for more updates and behind-the-scenes features as we celebrate the legacy—and the future—of The War of the Roses. The battle begins again in 2025. Look for the stage adaptation of THE WAR OF THE ROSES on the West End in 2026 and then Broadway in 2027.
