"Supergirl: Woman of Tomorrow" Star Milly Alcock Shares First Set Photo as Filming Begins

Production has begun on “Supergirl: Woman of Tomorrow,” the second feature in the newly rebooted DC Universe to secure its place on the release calendar, following DC Studios co-chief James Gunn’s “Superman.”

To commemorate the start of production on “Supergirl: Woman of Tomorrow,” star Milly Alcock and Gunn have shared the first image from the set of the film.

“Thrilled to see cameras roll at Warner Bros. Studios Leavesden on ‘Supergirl,'” Gunn posted to social media, also calling out Alcock, director Craig Gillespie, screenwriter Ana Nogueira, and Tom King and Bilquis Evely, who wrote and designed the 2022 eponymous comic that inspired the movie. 

The comic book takes Supergirl away from Earth as she travels through the cosmos with her trusty canine, Krypto the Superdog, in order to escape a life stuck perpetually under the shadow of her cousin, Superman. She encounters an alien girl named Ruthye, who is bent on revenge for the death of her father and recruits Supergirl to help her.

Alcock is joined by Matthias Schoenaerts (“The Old Guard”), who plays the lead villain, Krem of the Yellow Hills; Eve Ridley (“3 Body Problem”) as Ruthye Marye Knoll, the girl who recruits Kara Zor-El (a.k.a. Supergirl) to bring Krem to justice for killing her father; and David Krumholtz (“Oppenheimer”) and Emily Beecham (“Cruella”) as Supergirl’s parents.

Jason Momoa will also appear as the alien mercenary Lobo, and Krypto the Superdog will be along for the ride.

Alcock, a standout in the first season of HBO’s “House of the Dragon,” was cast as Kara Zor-El almost a year ago after she auditioned wearing the Supergirl suit on the set of Gunn’s film, “Superman,” which has caused widespread (and, as yet, unconfirmed) speculation that she’ll first appear as Supergirl alongside her Kryptonian cousin when “Superman” premieres in July.

In his first presentation of the DC Studios slate with co-chief Peter Safran, Gunn said that this version of Supergirl will be “much more hardcore,” because Kara grew up watching the destruction of Krypton before she arrived on Earth. “She’s not exactly the Supergirl we’re used to seeing,” Gunn said.

“Supergirl: Woman of Tomorrow” is slated to debut on June 26, 2026.
