The first poster for Supergirl has been released following Milly Alcock's debut as the Girl of Steel in Superman this past weekend.
"Look Up" was the tagline for the Man of Steel's DCU debut, but the script is flipped here, and it's changed to "Look Out." Given what we've seen from the DCU's Kara, that seems appropriate.
In Superman's closing moments, a drunk Supergirl shows up at the Fortress of Solitude to retrieve her dog, Krypto. She quickly takes her leave, with Kal-El telling "Gary" (a.k.a. Superman Robot #4) that she likes to go and drink on planets with a red sun because their metabolism means they can't get that same buzz on Earth.
During a recent interview with Screen Rant, DC Studios co-CEO James Gunn shared new insights into what fans can expect from the DCU's Woman of Tomorrow.
"She's a mess. She's a total mess," he teased. "I mean, I think as we learn, she's had a completely different background from Superman. A much more difficult background. He's had this wonderful upbringing by these two parents that loved him and were very healthy. And her background was much different than that. And she's ended up different than her cousin."
Last month, Gunn was asked how much of Kara Zor-El's backstory on Krypton will be explored in her upcoming solo feature.
"[Flashbacks to Krypton are] always a possibility. But I think those things are really integral to the two characters and the differences between them, and that Clark really does have sort of this really happy childhood," the filmmaker explained. "I mean, he had parents who loved him in an easy-going upbringing, and it makes him the least dysfunctional of superheroes in so many ways."
"And Supergirl, especially the DCU Supergirl, she’s kind of a mess. I mean, she’s had real issues growing up," Gunn teased. "And it is based on the comic where she watched person after person after person dying in front of her as her piece of the planet disintegrated."
In Supergirl: Woman of Tomorrow, Supergirl travels across the galaxy to celebrate her 21st birthday with Krypto the Superdog. Along the way, she meets a young woman named Ruthye and winds up on a murderous quest for revenge.
The cast includes Milly Alcock as Supergirl, Eve Ridley as Ruthye Marye Knoll, Matthias Schoenaerts as Krem of the Yellow Hills, Jason Momoa as Lobo, David Krumholtz as Zor-El, and Emily Beecham as Alura In-Ze. Craig Gillespie directs from a script by Ana Nogueira.
Supergirl: Woman of Tomorrow arrives in theaters on June 26, 2026.
