Overnight saw the news break of which lucky actor would be taking on the role of Supergirl herself in the upcoming Supergirl: Woman of Tomorrow movie - and House of the Dragon fans are in for a treat.

Not only that but we now know who will be taking on the main role.

Monday night saw DC studios boss James Gunn confirm that House of the Dragon star Milly Alcock will be taking on the role of Kara Zor-El AKA Supergirl. The Australian actress has had a number of small roles but is most known for playing a young Rhaenyra Targaryen in the Game of Thrones spin-off show.

“Milly is a fantastically talented young actor, and I'm incredibly excited about her being a part of the DCU," Gunn shared in an Instagram post. "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."

Tom King, the writer of the Supergirl: Woman of Tomorrow comic, also took to social media to share his excitement over the casting. "She's Supergirl and she doesn't give a #%*# about slings and arrows," he wrote. "Perfect casting. Couldn't be more excited to see Supergirl: Woman of Tomorrow, the world @bilquis built, brought to life by this incredible actor. Insanity. It started so small."

Not only that but Alcock also took the time to reveal the news to her fans via Instagram. “So excited to be a part of the DC fam - thank you so much to James Gunn for trusting me with Kara / Supergirl,” she wrote, alongside art of Supergirl herself.

Supergirl: Woman of Tomorrow is yet to receive a release date but with such a talented actress at the helm, it will definitely be one to stay up to date on.
