In what's easily the biggest casting decision for James Gunn's upcoming DC Universe reboot this year, Gunn and Peter Safran have confirmed that the Australian actress, Milly Alcock, will portray Supergirl in the upcoming reboot.
Alcock, renowned for her portrayal of the younger version of Princess Rhaenyra Targaryen in HBO's House of the Dragon, has been confirmed to play Kara Zor-El, better known as Supergirl.
The news follows a comprehensive global casting search, with Alcock securing the role over notable contenders such as Emilia Jones and Meg Donnelly.
James Gunn, the director, co-producer, and writer of Superman: Legacy, shared his excitement about Alcock's casting on Instagram, expressing his admiration for her talent. Gunn highlighted her varied auditions and screen tests for the role of Supergirl, which convinced him of her fit for the character as envisioned by the comic creators Tom King and Bilquis Evely as well as playwright Ana Nogueira. The upcoming Supergirl: Woman of Tomorrow, currently being scripted by Nogueira, will feature Alcock in the lead role.
While Alcock's debut in the DCU is confirmed, the specifics of her first appearance remain uncertain. It's speculated that she'll appear in Superman: Legacy, which begins filming in Atlanta in the spring, but no official confirmation has been provided yet. However, it's expected she'll feature in a DC project before her solo feature, Supergirl: Woman of Tomorrow, takes the center stage.
