Released yesterday (July 16) by DC Studios co-chief James Gunn, it shows the eponymous hero sipping on a Slurpie as she poses next to the immediately recognizable 'S' symbol that adorns her and fellow Kryptonian Superman 's outfits.

While we still won’t see Supergirl: Woman of Tomorrow hit our theaters until next year, ahead is everything we know so far. On Jan. 29, 2024, Deadline revealed that House of the Dragon actress Milly Alcock will be playing the role of Kara Zor-El.

Jason Momoa channels Lobo and has the perfect response to James Gunn's reveal of the first Supergirl movie poster.

The poster features Alcock wearing a long brown trench coat over her Supergirl suit, while also teasing her character’s vibes. It also shows a playful spin on Superman’s DCU tagline “Look Up,” seemingly hinting at the messy chaos she’ll be bringing into the DCU.

Before long, it'll be Supergirl's turn to take flight. Milly Alcock debuted as the Girl of Steel in the new film, swooping in to scoop up her dog, Krypto, and demonstrating a palpable disinterest in her super-powered cousin, Superman ( David Corenswet ).

Milly Alcock's Supergirl has a brief but hilariously memorable cameo in James Gunn's Superman, establishing her party girl persona along with the basic facts that she's Superman's cousin, and that she's been off-world. And as we see in the movie, the DCU's Kara Zor-El is what James Gunn tells ScreenRant is a "total mess."

Everything we know about the future of the DC Universe, from cast and crew to release dates, plus all of the DC Elseworlds projects.
