Over the past month, casting directors have been actively seeking a new Supergirl, with various actresses vying for the coveted role. Among the contenders are Emilia Jones, recognized for her work in "Locke & Key," and Meg Donnelly, known for lending her voice to Supergirl in "Legion of Superheroes." Yet, it is Milly Alcock, emerging as a breakout star from "House of the Dragon," who has been selected to portray the Woman of Tomorrow.


This one is true. Welcome to the DCU, Milly Alcock!" DC Studios co-head James Gunn confirmed on social media Monday.


Milly Alcock has landed the coveted role of Supergirl and is set to make her debut in the highly anticipated film "Superman: Legacy," slated for release next year. Joining her in this cinematic universe are acclaimed actors such as David Corenswet as Superman, Rachel Brosnahan of "The Marvelous Mrs. Maisel" fame portraying Lois Lane, and Nicholas Hoult, known for his role in "Mad Max: Fury Road," embodying the iconic villain Lex Luthor, among a stellar ensemble of performers tackling beloved comic book characters.

After her appearance in "Superman: Legacy," the actress is scheduled to star in her own DC Studios film titled "Supergirl: Woman of Tomorrow." According to DC executives James Gunn and Peter Safran, the upcoming "Supergirl" movie will be adapted from the comic book series titled "Supergirl: Woman of Tomorrow," authored by Tom King and illustrated by Bilquis Evely. This comic series was released in July of the preceding year.


This is a very different type of Supergirl,” Gunn said. “In our [film], we see the difference between Superman, who was sent to Earth and raised by loving parents from, you know, the time he’s an infant, versus Supergirl, who was raised on a rock chip-off of Krypton and watched everyone around her die and be killed in terrible ways for the first 14 years of her life, and then came to Earth when she was a young girl and is much more hardcore. She’s not exactly the Supergirl we’re used to seeing.”


Alcock joins a notable line of actresses who've portrayed Supergirl, such as Melissa Benoist in the long-standing "Supergirl" series and Sasha Calle in "The Flash" movie. James Gunn's emphasis on a fresh start with the new DCU indicates a departure from prior character portrayals.

"Superman: Legacy," hitting theaters on July 11, 2025, is set to serve as a cornerstone of "Gods and Monsters," the initial phase of the new cinematic universe. As of now, a release date for the Supergirl movie has not been announced.
