Milly Alcock is the New ‘Supergirl’!

, Big news from the DC Universe – Milly Alcock has been cast as the new Supergirl!

While there’s been lots of speculation about who might be getting the role, filmmaker and DC boss James Gunn confirmed the House of the Dragon star had scored the role when he reposted a headline on social media.

“This one is true,” he wrote on Threads. “Welcome to the DCU, Milly Alcock!”

Similarly, he shared a message on his official Instagram account describing Milly as “a fantastically talented young actor.” He added, “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.”

Milly catapulted to global stardom with her portrayal of Rhaenyra Targaryen in the Game of Thrones spinoff. The 23-year-old Aussie actor is also known for her roles in Upright, Pine Gap and Fighting Season.

Supergirl: Woman of Tomorrow will follow the release of Superman: Legacy which stars David Corenswet in the title role, Nicholas Hoult as Lex Luthor and Rachel Brosnahan as Lois Lane.

Supergirl or Kara Zor-El  first appeared in a 1959 edition of Action Comics as the cousin of Clark Kent. It wasn’t until 1962 we began to see more of her and this continued right up until the mid-80s (where she was sadly killed off – but don’t worry, she was brought back to life in later years.)

The character has been portrayed by a number of talented women over the years including Helen Slater in the original 1984 Supergirl film, Laura Vandervoort in the Smallville series, Melissa Benoist in the Supergirl series and Sasha Calle in the more recent The Flash film.
