Supergirl teaser trailer delivers party vibes, action, and attitude

James Gunn's relaunch of the DC Universe is looking up. Following the box office success of Superman, this resurging superhero franchise is next offering Supergirl, a flashy spinoff that's giving Guardians of the Galaxy energy with this first trailer.

Maybe it's Blondie blasting "Call Me" across footage of Supergirl partying and crashing alongside her lovable superpup, Krypto. Maybe it's the collision of outer space shenanigans, rock 'n' roll, and eye-popping action. But we are seated to see House of the Dragon's Milly Alcock reprise the role of Kara, Superman's enchantingly chaotic cousin.

Based on the comic mini-series Supergirl: Woman of Tomorrow, written by Tom King and illustrated by Bilquis Evely, this movie will follow Kara on her party odyssey, which crashes into a quest to help an alien girl named Ruthye Marye Knoll (Eve Ridley) seek justice.

Craig Gillespie (I, Tonya, Cruella) directs Supergirl, with a screenplay by Ana Nogueira. Joining Alcock and Ridley in the superhero action are Matthias Schoenaerts, David Krumholtz, Emily Beecham, and Jason Momoa, who is not playing Aquaman here. Nearly a year ago, Momoa announced on Instagram he'd been asked to play Lobo, a hulking anti-hero who works as an interstellar bounty hunter.

Supergirl opens only in theaters June 26, 2026.
