Richard Kelly’s ‘Donnie Darko’ sequel novel reportedly due in December 2026

Gold Derby reports that Kelly has finished The Philosophy of Time Travel, a 600-page sequel novel due in December 2026. It follows the Darko family over 14 months; early pages appeared on the film’s interactive website while the book was unfinished. Kelly hopes the novel could lead to more films and favors motion-capture animation, but Gold Derby describes those films as hopes, not announced productions.
