Milly Alcock, known for her breakout performance in HBO's House of the Dragon, has been cast as Supergirl in James Gunn’s upcoming DC Universe movie, Supergirl: Woman of Tomorrow. Alcock was picked ahead of Emilia Jones and Meg Donnelly for the coveted role. The film, based on a 2022 comic book series and written by Ana Nogueira, will feature Alcock portraying a darker and more hardcore version of Supergirl, deviating from the traditional portrayal of the character. The movie, part of Gunn's and Safran's new DC Universe projects, is highly anticipated, and Alcock's performance is expected to add a unique dimension to the superhero narrative.
