James Gunn’s new DCU is getting ready to launch in cinemas all over the globe next year with the release of Superman. But just one year later, Kal-El’s cousin Kara, a.k.a Supergirl, is hitting the big screen as well, in the character’s first feature film in over 40 years. Originally titled Supergirl: Woman of Tomorrowit seems the film will now just be Supergirl. This isn’t shocking considering Superman: Legacy eventually became Superman. Gunn himself commented on it during a Rolling Stone interview, saying “I think its just called Supergirl” and noting that he’s always cutting things.
After seeing Supergirl in Superman for a very fun cameo, James Gunn gave fans the gift of this very rad poster. She’s absolutely a wild child to look out for, indeed.
Here’s everything we know so far about DC Studios’ upcoming movie about the Girl of Steel, Supergirl.
Title
Like the comic book upon which it is based, the title of the film was once Supergirl: Woman of Tomorrow but now it is Supergirl. It will be the second film in James Gunn’s Chapter 1 of his new DCU, titled “Gods and Monsters.”
Supergirl’s Plot
Based on the 2021-2022 series of the same name by Batman writer Tom King and artist Bilquis Evely, the film will be a grand intergalactic adventure. In this story, Kara Zor-El, Superman’s young cousin, will embark on a journey through space on her 21st birthday. Joining her on this adventure is Krypto the Superdog. In space she meets a young alien girl named Ruthye who asks Kara for her help in getting revenge for the killing of her family by a man known as Krem of the Yellow Hills. Kara is far more jaded than her cousin Kal-El, who came to Earth as a baby. In stark contrast, this version of Kara witnessed the destruction of her home planet at age 14, changing her outlook on life going forward.
Behind-The-Scenes
Supergirl is directed by I, Tonya and Cruella director Craig Gillespie, from a script by Ana Nogueira. Although she has written screenplays before, most know Nogueira from her role in the CW series The Vampire Diaries. DC Studios co-heads James Gunn and Peter Safran are producing. Of Nogueira, Gunn said “Ana is an amazing writer whose screenplay adaptation of Woman of Tomorrow is above and beyond anything I hoped it would be.”
He later said (via The Hollywood Reporter) “[Writer] Anna [Nogueira] came in, and she pitched the story to me of Supergirland it was just one of the best pitches I’ve ever heard, and she immediately wrote it. She came in with the first draft that was great, and it’s just gotten better and better. Then [director] Craig [Gillespie] has been incredibly easy to work with, and I can’t wait for that to come out.”
On January 23, 2025, Gunn shared a photo of star Milly Alcock sitting in a director’s chair with the Supergirl logo on it. He explained that cameras are rolling on what will be the DCU’s second feature.
Supergirl’s Cast
Our titular woman of tomorrow is none other than House of the Dragon star Milly Alcock. As fans probably know, she played the younger Princess Rhaenyra Targaryen in the first season of that series. Joining her is Belgian actor Matthias Schoenaerts, famous for his role in Netflix’s The Old Guard. Here, he’s the antagonist of the film, Krem of the Yellow Hills. Although not confirmed, we imagine there will be some kind of smaller role for David Corenswet as Kara’s cousin Superman.
Eve Ridley will also star in the film as Ruthye Mary Knolle. This character is central to the comics that the film is based on, in which this alien girl discovers the death of her father by a villain named Krem. Her quest for vengeance leads to a team up with Kara for justice.
In a move both totally surprising and not at all surprising, Jason Momoa—Aquaman in the DCEU—has been cast as Lobo in the DCU, to make his first supporting appearance in Supergirl.
David Krumholtz (Oppenheimer) and Emily Beecham (1899) have been cast in the film as Kara’s parents, Zor-El and Alura, respectively. Presumably they will feature in flashbacks since the characters are canonically dead by time Supergirl is awakened on Earth.
Supergirl‘s Release Date
Supergirl is set to release in theaters worldwide on June 26, 2026.
