For the eponymous Supergirl (Milly Alcock), however, that imperviousness is just an excuse for an extended pub crawl across different planets. Supergirl, which premiered in cinemas June 26, marketed itself as a story about the intergalactic adventures of a loveable antihero. The character of Supergirl briefly cameoed during the 2025 James Gunn adaptation of Superman. The Supergirl film was announced in January 2023 as an adaptation of the critically acclaimed 2021–22 comic book miniseries Supergirl: Woman of Tomorrow by Tom King and Bilquis Evely, a finalist for Best Graphic Story or Comic at the 2023 Hugo Awards. Most notably, the film heavily stunts the character development of both protagonists that propelled the original narrative of Supergirl: Woman of Tomorrow.
