Supergirl is finally set to headline her own feature film, with a global theatrical release scheduled for June 26, 2026. The film is part of DC Studios’ Chapter One: Gods and Monsters and follows the events of James Gunn’s Superman, bringing the iconic Kryptonian heroine back to the big screen for the first time in over four decades.
Below is a comprehensive breakdown of everything we know so far, including the release date, casting details, storyline insights, and how the film fits into the broader DC Universe.
Release Date
DC Studios has confirmed that Supergirl will debut on June 26, 2026, nearly a year after Superman introduced the new DCU continuity.
Principal photography wrapped in early May 2025, meaning the film is now in post-production and remains firmly on track for its summer 2026 release.
Trailer Status
An official trailer has not been released yet, and fans shouldn’t expect one at San Diego Comic-Con in July 2025. James Gunn has indicated that the studio will focus on promoting Peacemaker Season 2 at that event.
However, sources suggest that a first look could debut at a major fall convention like New York Comic Con. Until then, a teaser image posted by Gunn in March offers a behind-the-scenes glimpse of Milly Alcock as Supergirl on set.
Cast: Confirmed and Rumored
- Milly Alcock as Kara Zor-El / Supergirl
- Jason Momoa as Lobo
- Matthias Schoenaerts as Krem
- Eve Ridley as Ruthye Marye Knoll
- David Krumholtz as Zor-El
- Emily Beecham as Alura In-Ze
Alcock, best known for her breakout role in House of the Dragon, won the role after a final showdown with Zombies star Meg Donnelly. She made her first appearance in the DCU with a surprise cameo in the closing moments of Superman, setting up her journey to come.
Jason Momoa’s casting as the galactic bounty hunter Lobo is one of the biggest surprises. While the character isn’t featured in the original Woman of Tomorrow comic storyline, Gunn has hinted that Lobo will be integral to the film’s plot.
Matthias Schoenaerts is confirmed as the film’s primary antagonist, Krem, who sets the story in motion by murdering the father of Ruthye, played by Eve Ridley. The film will also delve into Kara’s past on Krypton, with Krumholtz and Beecham portraying her parents in what’s expected to be a series of flashbacks.
Fan-favorite Krypto the Superdog will also return, continuing his brief but memorable appearance alongside Kara at the end of Superman.
Story and Inspiration
Supergirl is heavily based on the acclaimed 2021–2022 comic series Supergirl: Woman of Tomorrow by Tom King and Bilquis Evely. While the film has now officially dropped the subtitle, insiders suggest the adaptation will remain true to the spirit and structure of the source material.
The story follows Kara Zor-El as she crosses paths with Ruthye, a young girl seeking vengeance for her father’s murder. Kara, initially reluctant, agrees to help Ruthye hunt down the killer Krem, launching a galaxy-spanning adventure that challenges Kara’s morality, emotional resilience, and legacy as a Kryptonian.
What sets Woman of Tomorrow apart and may carry into the film is the narrative perspective. The comic is told through Ruthye’s eyes, not Kara’s. It remains to be seen whether the film will follow this approach or focus more directly on Alcock’s Supergirl.
Expect a darker, more philosophical tone compared to previous Superman-family stories. Gunn has hinted the film will explore Kara’s emotional complexity, describing her as a character who has experienced far more trauma than her cousin Kal-El. Despite the gritty themes, the movie is likely to retain a PG-13 rating, with Gunn aiming for broad accessibility.
Place in the DCU
As the second theatrical release in DC Studios’ rebooted continuity, Supergirl will build on the foundation laid by Superman and follow projects like Creature Commandos (animated) and Lanterns (TV).
While its long-term impact on the DCU remains unclear, Warner Bros. Discovery CEO David Zaslav confirmed that Supergirl is one of the franchise’s key pillars, alongside Superman, Batman, and Wonder Woman.
With a larger role planned in future DCU phases, this film is just the beginning for Alcock’s Supergirl.
What’s Next?
After Supergirl, the only other known DCU project in active development is Clayface, a horror-leaning spin-off being helmed by Mike Flanagan, slated for a September 2026 release. For now, fans eagerly await the first trailer and more plot details.
In the meantime, if you’re curious to learn more about the inspiration for the film, the Supergirl: Woman of Tomorrow graphic novel is available now and well worth a read.
