James Gunn’s may have kicked off a fresh era of sincere superhero storytelling, but it also laid the groundwork for what could be the wildest origin story of all time. Now that the Last Son of Krypton has arrived in the new DC Universe in 2025, his fiery-tempered cousin Kara is right on his heels.
Supergirl will be the second theatrical installment of , and one of the most highly anticipated films of 2026. Kara Zor-El hasn’t had a true solo film spotlight in decades— and while wasn’t exactly well-received, the CBS/CW series starring Melissa Benoist fared better.
But this is an all-new DCU now, and Gunn and his team aim to propel Supergirl into the mainstream by drawing from a story by acclaimed comics writer Tom King and enlisting director Craig Gillespie. This reboot is set to add edgier layers to the new DC, so here’s everything you need to know about Supergirl— including its release date, trailers, and star-studded cast, which features Jason Momoa’s return to the DC Universe as intergalactic mercenary Lobo.
What is the Supergirl release date?
Fans won’t have to wait long for the next DCU chapter. Supergirl is scheduled to hit theaters nearly a year after Superman’s July release date, premiering on June 26, 2026.
Who is directing Supergirl?
The DCU has tapped an unconventional yet intriguing director to helm Supergirl: . The filmmaker has carved out a niche crafting stories about misunderstood, feisty heroines— from I, Tonya to Cruella— making him a perfect fit to bring a more abrasive version of Supergirl to life.
What is the plot of Supergirl?
Supergirl was originally titled Supergirl: Woman of Tomorrow, a clue that should resonate with comic fans. Woman of Tomorrow is an eight-issue series by Tom King that radically redefined Kara’s role in the DC Universe.
The series introduces Kara at a low point. Like Superman, she was sent from Krypton to Earth to protect and raise baby Kal-El— but after being knocked off course and trapped in the Phantom Zone for decades, she arrives to find her cousin already a fully grown superhero.
This jarring awakening leaves Kara without purpose; she wastes her days partying on red-sun planets until an alien girl named Ruthye recruits her for a revenge quest. The pair embark on a harrowing galactic adventure that eventually helps Kara find a new path forward.
It’s unclear how much the film will borrow from King’s plot, but given the similarities between her comic introduction and , it could be a faithful adaptation.
Who is in the cast of Supergirl?
House of the Dragon star Milly Alcock will play Kara Zor-El (aka Supergirl), and she’ll share the screen with Jason Momoa. A fixture of the previous DC era as Aquaman, Momoa has been recast as anti-hero Lobo— a role he’s long coveted, even hinting at it while promoting Aquaman and the Lost Kingdom.
“I always wanted to play Lobo, because I’m like, ‘Hello? It’s the perfect role,” he told Fandango. “If they call and ask me to play him, it’s a f*** yeah.”
Fortunately, Gunn felt the same way. “I’ve loved watching Jason bring [Lobo] to life,” he shared in a post on . “Can’t wait to share that with all of you.”
Alongside Alcock and Momoa, Supergirl has officially cast two more characters:
- Eve Ridley (3 Body Problem) will portray Ruthye Mary Knolle, an honor-bound alien warrior seeking Supergirl’s help to hunt her father’s killer.
- Matthias Schoenaerts (The Old Guard) has been tapped to play Krem of the Yellow Hill— Ruthye’s revenge target and Supergirl’s main villain.
Is there a Supergirl trailer?
In addition to a few teasers, there’s one full trailer for Supergirl with a distinct Guardians of the Galaxy vibe. The trailer also highlights that this movie will be a key part of the new DCU.
As of January 23, 2026, Gunn and Momoa have released a short teaser focused solely on Lobo, who sports his iconic intergalactic biker look.
How many Supergirl movies will there be?
So far, Alcock is attached to star in only one Supergirl film— no plans for Supergirl 2 have been announced yet. But we’ll likely see her in multiple DCU projects beyond her solo adventure. Gunn has teased plans for a “” at the end of DC’s first chapter, and whether that’s the Justice League or not, Kara will probably be involved.
