House of the Dragon star Milly Alcock is no stranger to playing formidable heroines, and she’s getting ready to do it again! The Australian actress will join James Gunn and Peter Safran’s new DC Universe as Kara Zor-El/Supergirl.

Alcock landed several TV roles in her home country of Australia as a teen, before rising to prominence as the young Princess Rhaenyra Targaryen in HBO’s Game of Thrones spin-off House of the Dragon. She’s been looking for her next big role ever since, and her search finally came to an end when she defeated Emilia Jones and Meg Donnelly to be cast as Supergirl.

James Gunn confirmed her casting on social media and said he’s incredibly excited about her being a part of the DCU. He described her as “a fantastically talented young actor” and added he was blown away by her varied auditions and screen tests for Supergirl.

Alcock is expected to lead her own DCU standalone movie, Supergirl: Woman of Tomorrow, but this project won’t mark her debut as Kara Zor-El. She’s expected to appear in another DC-based project before flying solo, but it’s still unclear if that project will be 2025’s Superman: Legacy, led by David Corenswet and Rachel Brosnahan.
