Who was cast as Supergirl for an upcoming movie – Meet the New Hope
Who was cast as Supergirl for an upcoming movie? The answer landed with a cheer from fans and critics alike: Milly Alcock, the breakout star of House of the Dragon, will don the cape of Kara Zor‑El in DC Studios’ freshly rebooted universe.
1. Milly Alcock’s Breakthrough Moment
In January 2024, DC Studios unveiled Milly Alcock as the new Supergirl. This is a full circle moment for Alcock—rising from Rhaenyra Targaryen’s younger self to carrying the superhero legacy of Krypton. DC co‑head James Gunn confirmed: “Welcome to the DCU, Milly Alcock!”
2. Debuting in Superman: Legacy
Alcock’s first appearance won’t be in her solo film, but in Superman: Legacy (July 11, 2025), alongside David Corenswet’s Superman and Rachel Brosnahan’s Lois Lane. She’ll then lead Supergirl: Woman of Tomorrow, adapted from Tom King’s beloved comic run.
3. Supergirl: Woman of Tomorrow Cast and Crew

The upcoming Supergirl film, slated for June 26, 2026, will be directed by Craig Gillespie (I, Tonya) and written by Ana Nogueira. Alcock reprises Kara Zor‑El, joined by Matthias Schoenaerts (villain Krem), Eve Ridley (Ruthye), and Jason Momoa as Lobo.
4. The Intense Screen Test Journey
Alcock has shared how nerve‑wracking the casting process was: intense screen tests, layered acting choices, and emotional stakes. She nailed her audition by blending vulnerability with Kryptonian power—a balance the role demands.
5. What This Means for the DCU
This casting signals a shift in tone: from The Flash’s Sasha Calle (who introduced Supergirl in 2023) to a deeper, more textured narrative in the new DC Universe. The film is intended as part of Chapter One: Gods and Monsters, offering a fresh start.
