DC just dropped the first trailer for Supergirl, and it’s a game-changer. Milly Alcock’s Kara Zor-El is a traumatized, hard-drinking Kryptonian unlike any we’ve seen, while Jason Momoa finally makes his debut as the brutal bounty hunter Lobo. Director Craig Gillespie and DC boss James Gunn promise a dark, emotional, and authentic adaptation of the celebrated Woman of Tomorrow comic book, setting a bold new tone for the DC Universe.
The first official trailer for DC Studios’ Supergirl has arrived, and it immediately establishes that this is not the Girl of Steel you remember. Led by House of the Dragon breakout star Milly Alcock, the footage paints a portrait of a hero forged in trauma and cynicism, a stark departure from her famously optimistic cousin. This is Kara Zor-El, a survivor who is more interested in hard truths than high ideals, and she’s about to take the DC Universe on a dark, cosmic journey.
Not Your Cousin’s Superhero
The trailer wastes no time drawing a line in the sand between Supergirl and Superman. “He sees the good in everyone, and I see the truth,” Alcock’s Kara declares, her voice laced with a weariness that speaks volumes. This isn’t just a tagline; it’s the core of her character. While Clark Kent was raised by loving parents on Earth, Kara witnessed the horrific destruction of her home planet.
“Krypton didn’t die in a day,” she explains. “The Gods are not that kind.” This single line reframes her origin story from a tragic event to a prolonged, agonizing nightmare. DC Studios co-head James Gunn confirms this foundational difference is the entire point. “She grew up and watched every single person around her that she loved die in a horrible way,” Gunn stated. “She’s bitter, and she’s jaded, and she’s messed up, and that’s where we start with her.”
We see this bitterness in action, with clips of Kara throwing back shots on a distant alien world. For the uninitiated, this is more than just a character quirk. The planet is bathed in the light of a red sun, which nullifies Kryptonian invulnerability, allowing her to feel the effects of alcohol—a desperate attempt to numb a pain that is otherwise inescapable.
The ‘Woman of Tomorrow’ Promise
The film is a direct adaptation of the critically acclaimed Supergirl: Woman of Tomorrow comic series by writer Tom King and artist Bilquis Evely. Both Gunn and co-head Peter Safran have called this an “authentic adaptation,” signaling a commitment to the source material’s mature themes and emotional depth.
The plot, teased in the trailer, follows Kara as she’s approached by a young alien girl, Ruthye Marye Knoll (Eve Ridley), who seeks help in avenging the murder of her family. Their target is the ruthless Krem of the Yellow Hills, played by Matthias Schoenaerts. Schoenaerts’ involvement brings its own real-world context, as the actor has recently faced legal troubles, a detail reported by Entertainment Weekly.
Director Craig Gillespie (I, Tonya, Cruella) praised Alcock for embracing the character’s darkness. “She’s got a lot of baggage and a lot of demons coming into this, which is very different than where Superman is in his life,” he explained. “It’s really surprising, the headspace she’s in and the journey she goes on, for a typical superhero movie, which this is not.”
Enter The Main Man: Jason Momoa’s Lobo
Perhaps the trailer’s biggest shockwave for fans was the official first look at Jason Momoa as Lobo. After years of speculation about his future in the DCU post-Aquaman, the footage delivers a definitive answer. In a perfectly framed shot, Momoa emerges as the infamous Czarnian bounty hunter, chomping on a cigar with a menacing grin.
It’s a role Momoa has publicly campaigned for, and his casting represents a major piece of the new DCU puzzle. Lobo’s irreverent, ultra-violent nature suggests that Supergirl will not shy away from the grittier corners of the DC cosmos. This single shot confirms that Gunn is willing to reinvent his universe’s actors in new roles, setting a powerful precedent for the franchise’s future.
Building a Bold New DCU
While the focus is on its troubled hero and brutal anti-hero, the film is also building out its world with a strong supporting cast, including David Krumholtz as Kara’s father, Zor-El, and Emily Beecham as her mother, Alura In-Ze. Peter Safran emphasized that while the film will be true to the comic, it’s designed for a broad audience, balancing “humor and pathos and emotion so well” to create a tone that is “unique among superhero movies.”
With its complex protagonist, mature source material, and the electrifying addition of Lobo, Supergirl is poised to be a foundational and defining chapter in Gunn’s new DC Universe. It’s a clear statement that the heroes of this new era will be complicated, challenged, and far from perfect.
Supergirl is scheduled to hit theaters in the U.S. on June 26, 2026, with an international release beginning on June 24, 2026.
