Australian actor Milly Alcock stars as Supergirl in this summer's new DC Studios movie bearing her name. Heading to theaters on June 26, the film finds her character on an intergalactic odyssey of revenge. DC Studios heads James Gunn and Peter Safran first noticed Alcock on the “Game of Thrones” prequel series “House of the Dragon.” Since she filmed her cameo for “Superman,” it's been a non-stop ride. Alcock says her character reminded her a lot of herself. She's finding the experience of sudden fame somewhat disorienting and laughs about anyone wanting a toy with her face.
