Supergirl Role Goes To ‘House Of The Dragon’ Star Milly Alcock

James Gunn and DC Studios have found their Woman of Tomorrow! It took a few weeks, but Gunn has named House of the Dragon star Milly Alcock as his new Supergirl. She’ll take on the role in a future Supergirl movie, and possibly appear elsewhere across the new DCU.

The Wrap confirmed the news of Alcock’s casting. She had been in contention along with CODA star Emilia Jones and Supergirl voice actress Meg Donnelly since January, so this wasn’t a long testing process and did not include Sasha Calle, who played the role most recently in The Flash. Some fans had been hoping she’d stick around, but when Gunn confirmed his Supergirl would be based on Tom King’s Supergirl: Woman of Tomorrow comic, that idea flew out the window.

This is only the seconf feature film role for Alcock, who previously starred in the 2018 Australian horror, The School.

No director is attached to the movie yet, but a script is being written by Ana Nogueira, who had been hired to write a Supergirl movie for Calle that obviously won’t happen. Because this casting is so early in the process, there’s a good chance we could see Alcock debut in Superman: Legacy, which Gunn plans to shoot this March for a July 2025 release.
