DC Studios has unveiled the first poster for Supergirl, and the new tagline tells fans everything they need to know about this version of Kara Zor-El: “Truth, Justice, Whatever.” The studio has also confirmed that the first trailer will debut on December 11 at 12 p.m. ET, 9 a.m. PT, 5 p.m. BST.
The attitude baked into the poster signals a sharp contrast between Supergirl and her cousin Superman. After her tense, but funny, introduction in Superman, it tracks that Kara would carry a harder, more jaded worldview as she steps into her own story.
The studio also confirmed that Ramin Djawadi of Game of Thrones fame is composing the score, an announcement that has only fueled anticipation for a movie already riding major buzz. The film draws inspiration from Tom King and Bilquis Evely’s acclaimed comic Supergirl: Woman of Tomorrow, a cosmic character study that redefined the hero for modern readers.
Fans are still speculating about DC Studios’ ongoing countdown, although tomorrow’s trailer reveal appears to be the payoff. Whether it will go head-to-head with an Avengers: Doomsday teaser is still uncertain.
Marvel Studios has not announced anything, but rumors are circulating that a planned Disney trailer for The Mandalorian and Grogu was delayed to avoid overshadowing Supergirl. That shift has prompted speculation that Avengers: Doomsday might drop closer to the release of Avatar: Fire and Ash next weekend.
A recently surfaced synopsis, believed to be official, sets the stage: “DC Studios’ Supergirl hits theaters this summer, starring Milly Alcock as Kara Zor-El/Supergirl. When an unexpected and ruthless enemy threatens, Kara Zor-El is forced, against her will, to team up with an unlikely companion.”
The synopsis continues: “Together, they embark on an epic cosmic journey where revenge and justice are at stake – and where Kara must confront her origins to find her own path as a hero. Alcock is joined by Matthias Schoenaerts, Eve Ridley, David Krumholtz, Emily Beecham, and Jason Momoa in key roles. Peter Safran and James Gunn are producing the film for DC Studios.”
The film follows Kara as she travels across the galaxy to celebrate her twenty-first birthday with Krypto the Superdog. She soon meets a young woman named Ruthye and becomes entangled in a quest for revenge that tests her morality, legacy, and identity.
