Supergirl Teaser Trailer is out an with that Supergirl’s long-awaited journey to the big screen has finally reached a pivotal moment. After years of development, setbacks, and creative retooling, the film is now moving forward with renewed momentum as part of James Gunn and Peter Safran’s reimagined DC Universe.
A Journey Marked by Turbulence
The road to bringing Supergirl to theaters has been anything but smooth. Development on the project began back in 2018, only to face significant obstacles along the way. A pandemic-related postponement in 2020 was followed by a complete scrapping of the project in 2022 when Warner Bros. Discovery’s new chief David Zaslav took over. The film’s fortunes shifted once again in 2023, when it was retooled as part of Gunn’s broader vision for transforming the DC Extended Universe into the DCU.
The casting changes further highlight the project’s complicated path to production. Sasha Calle, who was originally selected to play Kara Zor-El, even made an appearance in 2023’s The Flash, but ultimately did not continue with the Supergirl project. The character eventually found its match in House of the Dragon star Milly Alcock, who brings fresh energy to the iconic Kryptonian hero.
A Character Reimagined
Under the direction of Craig Gillespie, known for his work on I, Tonya, and with a script by Ana Nogueira inspired by the acclaimed comic-book miniseries Supergirl: Woman of Tomorrow by Tom King and Bilquis Evely, the film presents a distinctly different take on the superhero mythology. This version of Kara Zor-El is a universe-hopping party girl in her early twenties who finds herself thrust into intergalactic conflicts following a particularly self-indulgent birthday celebration. Her journey becomes intertwined with a mission of vengeance on behalf of an alien girl named Ruthye Marye Knoll, played by Eve Ridley, who seeks to bring down the villain Krem of the Yellow Hills—portrayed by Matthias Schoenaerts.
What sets this incarnation apart is its willingness to embrace the character’s flaws and complexity. Gillespie emphasized that this is fundamentally an anti-hero story, with Kara carrying significant emotional baggage and internal struggles. As the character herself notes in the trailer, while Superman “sees the good in everyone,” she “sees the truth”—a pointed contrast that defines her perspective. Gunn further elaborated on this approach, noting that female superheroes are frequently portrayed as perfect, whereas male superheroes have long been allowed to be imperfect. Supergirl breaks from that tradition, presenting a protagonist who is decidedly human in her messiness and contradictions.
An All-Star Supporting Cast
The film assembles a formidable ensemble to support Alcock’s lead. David Krumholtz takes on the role of Zor-El, while Emily Beecham plays Alura In-Ze. The cast also includes Jason Momoa in the role of Lobo, the notorious DC antihero, adding significant star power to the project.
Theatrical Release and Industry Context
Supergirl is scheduled to arrive in United States theaters on June 26, 2026. Despite external corporate pressures—including unexpected speculation about Warner Bros. Discovery’s future ownership—Gunn and Safran remain confident that the film will proceed without disruption. Safran noted that the franchise is positioned as an underdog with significant growth potential, telling reporters that “we’re just getting started” as the team continues to build momentum for the DCU.
The character’s cinematic debut marks a turning point for DC superhero adaptations, offering audiences a complex, flawed, and decidedly unconventional take on the Supergirl mythology that promises to challenge expectations and redefine what superhero storytelling can be.
