House of the Dragon star Milly Alcock has been cast as Supergirl in the DCU. The reported plan is for Alcock to first appear as Supergirl in a separate DCU project, possibly Superman: Legacy, before going on to lead her own solo movie, Supergirl: Woman of Tomorrow.

Alcock screen-tested for DC Studios bosses James Gunn and Peter Safran last week, along with Meg Donnelly, who was also in contention for the role. The character is expected to appear in a DC Studios project (or two) before her solo adventure, but it’s unclear if that project will be Gunn’s Superman: Legacy, which begins filming this spring, or another DC movie or show.

Alcock played young Rhaenyra Targaryen in the Game of Thrones spin-off series. She’s also appeared in 2018’s The School and 2020 series The Gloaming and Reckoning. She also has a main role in the series Upright, which has run for two seasons.

Supergirl: Woman of Tomorrow will be based on Tom King’s 2022 comic book series, which was illustrated by Bilquis Evely. No director has been set for the upcoming project.

"We see the difference between Superman, who was sent to Earth and raised by loving parents from the time he was an infant, versus Supergirl, who was raised on a rock, a chip off 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," said Gunn last year of the project. "She’s much more hardcore; she’s not exactly the Supergirl we’re used to seeing."
