Supergirl (2026) is an upcoming American superhero film based on the DC Comics character Kara Zor-El, also known as Supergirl. Directed by Craig Gillespie and written by Ana Nogueira, this marks the second film in James Gunn and Peter Safran’s reimagined DC Universe (DCU) following Superman (2025). Milly Alcock takes on the lead role, bringing a more hardened and battle-worn version of Supergirl to the screen. Set to release on June 26, 2026, the film is inspired by the 2021–22 comic book miniseries Supergirl: Woman of Tomorrow.
Supergirl’s character will contrast greatly with the hopeful tone of Superman, exploring darker themes like loss, trauma, and vengeance—delivering a space-faring epic that marks a tonal shift in the early stages of the DCU’s Chapter One: Gods and Monsters.

Key Questions Answered
What is the 2026 Supergirl movie about?
The story follows Kara Zor-El as she travels across the galaxy after experiencing deep personal tragedy. Accompanied by her loyal dog Krypto and a mysterious young girl named Ruthye Marye Knoll, Kara embarks on a vengeance-driven mission that tests her morals and strength. The journey showcases a Supergirl who is far more jaded than the traditional depiction, shaped by watching her loved ones die during Krypton’s destruction.
Is this a reboot of the Supergirl character?
Yes. This is a full reboot under the DCU. The character was previously portrayed by Sasha Calle in The Flash (2023) as part of the now-concluded DCEU. Milly Alcock’s Supergirl represents a darker, edgier take in line with the new cinematic direction outlined by Gunn and Safran.
Will Superman appear in this film?
While not officially confirmed, Supergirl does debut in Superman (2025), so there may be connections or references in her standalone film. A deeper crossover or team-up has not yet been announced, but this film is designed to expand the DCU’s intergalactic reach and character relationships.
Is Supergirl (2026) Worth Watching?
If you are a fan of science fiction, space operas, or character-driven superhero stories, Supergirl (2026) is shaping up to be a must-watch. Rather than simply mirroring Superman’s journey, the film explores trauma, resilience, and complex morality from the perspective of a Kryptonian raised in isolation and tragedy.
The film also introduces fresh energy to the superhero genre by focusing on a female protagonist who is not only powerful but flawed, emotional, and deeply humanized. The combination of Craig Gillespie’s directorial style and Ana Nogueira’s emotional screenplay offers a promising cinematic experience with emotional weight and thrilling action.
