Emerging actress Milly Alcock has been chosen for the role of Supergirl in the new DC Universe films helmed by James Gunn and Peter Safran.

The Australia-born Alcock played the young Princess Rhaenyra Targaryen in the first season of HBO’s Game of Thrones spinoff House of the Dragon.

Alcock first gained notice playing the young Princess Rhaenyra Targaryen in HBO’s hit prequel series House of the Dragon. She won the Supergirl role over other talented young actors like Emilia Jones of CODA and Meg Donnelly, who has voiced Supergirl in DC animated projects.

Details are still scarce, but there is speculation Alcock’s Supergirl could appear in Gunn’s upcoming Superman Legacy before starring in a solo Supergirl film. No director has yet been announced for the standalone Supergirl movie, which will be based on Tom King and Bilquis Evely’s 2022 Supergirl: Woman of Tomorrow comic series.

In announcing Alcock’s casting, Gunn emphasized how her take on the character will highlight Supergirl’s more tragic backstory compared to her famous cousin. Having watched Krypton’s destruction firsthand and endured great hardship before coming to Earth, this Supergirl promises to be a more hardened, gritty hero.

Gunn is clearly thrilled to have Alcock on board, raving about her auditions and calling her “a fantastically talented young actor.” With a rising star in the lead role, Supergirl’s future in the new DC Universe looks bright.

Gunn reposted Deadline’s story today on Instagram and confirmed it:

“This is accurate. Milly is a fantastically talented young actor, and I’m incredibly excited about her being a part of the DCU. Yes, I first became aware of her in House of the Dragon but I was blown away by her varied auditions and screen tests for #Supergirl. She embodies Kara as envisioned by @tomking_tk, @bilquis and Ana Nogueira.”
