Australian actress Milly Alcock has been cast to star as Kara Zor-El, also known as Supergirl, in the upcoming DC Universe film Supergirl: Woman of Tomorrow. The project, confirmed by DC Studios co-CEO James Gunn, will be a central component of the new cinematic slate overseen by Gunn and Peter Safran, marking a distinct departure from previous iterations of the character.
Who is Milly Alcock?
Milly Alcock is an Australian actress who gained international recognition for her portrayal of young Rhaenyra Targaryen in the HBO series House of the Dragon. Her performance in the Game of Thrones prequel earned critical acclaim and positioned her as a rising talent in Hollywood. According to Variety, Alcock secured the role of Supergirl after a rigorous audition process, reportedly impressing studio executives with her screen test.

What is Supergirl: Woman of Tomorrow about?
The film is based on the acclaimed comic book miniseries written by Tom King and illustrated by Bilquis Evely. Unlike traditional origin stories, the narrative follows Kara Zor-El as she journeys through space, accompanied by a young alien girl seeking revenge for the destruction of her home world.
James Gunn has publicly described the tone of the film as "science fiction epic" rather than a standard superhero movie. In a statement reported by The Hollywood Reporter, Gunn emphasized that the film will explore a version of Supergirl who was raised on a fragment of Krypton, witnessing her friends and family perish in tragic circumstances, which creates a grittier perspective than the version of the character raised on Earth.
How does this fit into the new DC Universe?
Supergirl: Woman of Tomorrow is a cornerstone of the "Gods and Monsters" chapter of the revamped DC Universe. This cinematic universe is designed to be more cohesive than previous DC film attempts, with Gunn and Safran acting as architects for the interconnected stories.
