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.

Slated for streaming on HBO Max in 2026, Lanterns is a mystery series that follows Hal Jordan (Kyle Chandler) and Jon Stewart (Aaron Pierre)—two of the most popular characters to have held the mantle of Earth's Green Lantern—as they investigate a murder in Nebraska.

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.

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

An A-lister makes an appearance in the new "Superman" movie, in reference to the hero's origin story.

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 ).

David Corenswet's new "Superman" is a hit. So what's next? A look at other movies and TV shows coming to the DC universe.

Supergirl is “a total mess,” according to James Gunn, but there’s a reason her DCU movie will be darker than Superman.

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.
