Warner Bros. DC Studios released the first trailer for its upcoming Supergirl film online in December 2025, with a high-profile airing ahead of Super Bowl Sunday on February 8, 2026. Starring Milly Alcock as a cynical, battle-hardened Kara Zor-El, the movie—directed by Craig Gillespie and adapting Tom King's Supergirl: Woman of Tomorrow comic—promises an interstellar journey of revenge distinct from Superman's optimism, arriving in theaters June 26, 2026.
The Supergirl trailer, set to Blondie's 'Call Me,' introduces Milly Alcock's Kara Zor-El—known from House of the Dragon—as a hungover, battle-hardened Kryptonian grappling with personal demons, including a drinking problem. Footage depicts young Kara meeting Krypto the Superdog as a puppy on a thriving Krypton before its destruction, with her narrating, “Krypton didn’t die in a day. The gods are not that kind,” while downing a flaming shot. It showcases Krypto's mischief, epic space battles, introspection on exile, and Kara's cynical worldview: “He [Superman] sees the good in everyone, and I see the truth.” This marks Supergirl's live-action DC Universe debut, following her cameo stumbling into Superman's fortress of solitude at the end of James Gunn’s 2025 film.
Plot and Setting
Drawn from Tom King’s 2022 comic illustrated by Bilquis Evely, the story follows Kara teaming with young alien Ruthye Marye Knoll (Eve Ridley) to hunt villain Krem of the Yellow Hill (Matthias Schoenaerts) across the galaxy after he kills Knoll’s father. Billed as an “epic, interstellar journey of vengeance and justice,” it evokes True Grit and unfolds entirely in outer space—unlike Gunn’s Earth-focused Superman—as confirmed by Gunn and Gillespie. The narrative emphasizes revenge, justice, and a darker, gritty take on the character versus the 1984 film.
Cast and Crew
Alcock leads alongside Schoenaerts, Ridley, David Krumholtz, and Emily Beecham as Kara’s parents. Jason Momoa appears as antihero Lobo; test screenings describe his role as substantial and crucial to the ending, though the actor has downplayed it as small, pending audience reaction. Ana Nogueira wrote the screenplay. Produced by Peter Safran and James Gunn, with executive producers Nigel Gostelow, Chantal Nong Vo, and Lars P. Winther. The team features cinematographer Rob Hardy, production designer Neil Lamont, editor Tatiana S. Riegel, costume designer Anna B. Sheppard, VFX supervisor Geoffrey Baumann, and composer Ramin Djawadi.
Reception and Test Screenings
Test screenings praise a darker tone than Superman, superior cinematography, and an intense action sequence rivaling Daredevil’s hallway fight.
DCU Context
With a 'completely blank slate' post-Superman, Gillespie crafted a tone 'so different' from its predecessor. Gunn highlights the film's messy, imperfect vibe contrasting Superman's idealism, positioning it as the next chapter in DC Studios' relaunched DC Universe.
