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.

The DC Universe version of Supergirl is “a total mess,” DC Studios co-CEO James Gunn has said now Superman is out in the wild.

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.

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

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."

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.

Gunn's latest, starring David Corenswet as the Man of Steel alongside co-stars Nicholas Hoult as Lex Luthor and Rachel Brosnahan as Lois Lane, has received rave reviews from fans and critics alike. So, naturally, the question on everyone's mind is, “when is Supergirl coming out?”
