Warner Bros. has been hinting all week that it was coming and finally dropped the long-awaited first extended teaser trailer for Supergirl, directed by Craig Gillespie and starring Milly Alcock in the title role.
Plans for a Supergirl movie date all the way back to 2018, but the merger that produced Warner Bros. Discovery scuttled the original concept. James Gunn and Peter Safran came in as co-CEOs of the new DC Studios and announced plans for a “soft reboot” of the DC universe, starting with this summer’s Superman. Sasha Calle played Supergirl for a brief appearance in 2023’s The Flash, but despite having signed a multi-year contract, Gunn and Safran decided to go in a different direction for their standalone film and cast Alcock (House of the Dragon) instead.
Gunn particularly wanted to distance this new version of Supergirl from earlier incarnations, especially how the character was portrayed by Melissa Benoist in the Arrowverse series that ran from 2015–2021. He wanted someone less earnest, more of a contrast to David Corenswet’s wholesome Superman. “This is a story-based medium; we want stories to be in theaters that are cool and different from each other,” Gunn said at a media briefing. “And this movie is not exactly just a female clone of Superman. It’s its own thing entirely. And with a character who’s equally worthy of this treatment.”
We met Alcock’s Supergirl briefly at the end of Superman, when she showed up to collect her dog Krypto, still a bit hung over from partying on a red-sun planet. She is more jaded than her cousin, having witnessed the destruction of Krypton and the loss of everything and everyone she loved. “He sees the good in everyone and I see the truth,” she says in the teaser.
Kara, aka Supergirl, is turning 23 and declares it will be the best year yet, which is admittedly “not a very high bar to clear.” While she might not be too keen on the prospect, she’s going to be a superhero nonetheless. Per the longline: “When an unexpected and ruthless adversary strikes too close to home, Kara Zor-El, aka Supergirl, reluctantly joins forces with an unlikely companion on an epic, interstellar journey of vengeance and justice.”
In addition to Alcock, the cast includes Matthias Schoenaerts as chief villain Krem of the Yellow Hills; Eve Ridley as Ruthye Marye Knoll, the aforementioned “unlikely companion” who meets and bonds with Supergirl over the course of the film; Ferdinand Kingsley as Ruthye’s father Elias; and David Krumholtz and Emily Beecham as Supergirl’s parents, Zor-El and Alura In-Ze. Jason Momoa also makes an appearance as Lobo, an alien bounty hunter from the planet Czarnia. We catch a brief, blurry glimpse of Momoa’s well-muscled mercenary with the glowing red eyes in the teaser. And of course, our favorite misbehaving pupster Krypto is returning, too; he kicks off the teaser by peeing on a newspaper.
Supergirl hits theaters on June 26, 2026.
