Milly Alcock/Instagram Supergirlfocuses on the titular superhero's journey as she teams up with a young warrior on a mission for revenge. House of the Dragon's Milly Alcock leads the cast, joined by Matthias Schoenaerts, Eve Ridley, and Jason Momoa. Supergirlis currently slated to debut in theaters on June 26, 2026. Warning: This article contains spoilers forSuperman(2025). The all-new DC Universe (DCU) is flying high thanks to the wildly entertaining animated seriesCreature Commandosand, of course, James Gunn's long-awaited take onSuperman. Against all odds (and plenty of pressure), the latter has already delivered in a big way, earning solid reviews from many critics and fans. While we atEntertainment Weeklyfound the script lacking, we nevertheless praised the flick forrestoring "light, humor, and romance to the DC universe." Before long, it'll be Supergirl's turn to take flight.Milly Alcockdebuted 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). It was a brief appearance, but enough to send fan hype into orbit. With her solo film on the horizon, here's everything we know aboutSupergirl, from its release date and cast to plot details and beyond. The upcomingSupergirlfilm is based on the eight-issue comic book miniseriesSupergirl: Woman of Tomorrow, created by Tom King and Bilquis Evely. It follows a lost and wandering Kara Zor-El (a.k.a. Supergirl) at a crossroads. She feels her life lacks purpose, especially since her baby cousin, Kal-El (Clark Kent/Superman), doesn't need her protection and is thriving on his own. Just as she's ready to give up, a young and noble galactic warrior named Ruthye Marye Knoll seeks her help in tracking down those responsible for killing her father and destroying her home. "She wants revenge, and if Supergirl doesn't help her, she'll do it herself, whatever the cost," readsthe comic's official synopsis. "Now a Kryptonian, a dog, and an angry, heartbroken child head out into space on a journey that will shake them to their very core." In January 2023, DC Studios co-CEO Gunn shared (viaThe Hollywood Reporter) that this version of Supergirl is darker and more complex. "We will see the difference between Superman, who was sent to Earth and raised by loving parents from the time he was an infant, versus Supergirl, raised on a rock, a chip off of Krypton, and who watched everyone around her die and be killed in terrible ways for the first 14 years of her life and then come to Earth," he said, adding, "She is much more hardcore and not the Supergirl we're used to." David Krumholtz/Instagram Supergirlsoars into theaters on June 26, 2026, a little less than a year followingSuperman's theatrical release. James Gunn/Instagram House of the Dragonstar Milly Alcock will step into the boots of the title character inSupergirl. After her casting was announced, Gunn shared onThreadsthat Alcock perfectly captured the vision of the character as imagined by King, Evely, and screenwriter Ana Nogueira. In aseparate post, Gunn said he recommended her for the role to DC Studios co-CEO Peter Safran over a year before her official casting, writing that he believed she could bring the "edge, grace, and authenticity" needed for this version of Supergirl. Alcock has kept details about the film and her role under wraps, joking thatshe "doesn't want to get sued."But in a May interview withElle Australia, she admitted feeling "absolute fear" when Gunn told her she'd landed the part. "I was kind of in disbelief. I was initially like, 'What have I done?'" she told the outlet before describing the screen test process, which was new territory for her. "During a screen test, you're in a room with all the other women [vying for the same part] and you're all dressed as the character," she explained. "[The studio] will get you lined up in the makeup truck and put the same makeup on you all and then test you on a stage. For Supergirl, it was myself and another girl. It was really scary; I thought I was going to vomit! But it's just fear! That's what happens! This job has been a journey of overcoming my own fear."

In January 2025,The Hollywood Reporterrevealed thatDavid Krumholtz(Oppenheimer) and Emily Beecham (Into the Badlands) costar as Supergirl's parents, Zor-El and Alura In-Ze, respectively. Jason Momoais set to make a cameo as Lobo, the alien mercenary and bounty hunter from the planet Czarnia. In a2023 interview with Fandango, Momoa revealed that Lobo has always been his favorite character, saying he "always wanted to play Lobo because I'm like, 'Hello? It's the perfect role.'" He added that if DC ever called him to play Lobo, he would jump at the chance — and now, he finally is. Momoa reiterated his love for the character in aMarch interview with EW: "I just think I'm the right person to play the role." He continued, "If we're going to typecast me in anything, let's put me in Lobo. Motorcycles, smoking cigars, partying, dreadlocks… loves a fight, funny." And of course, noSupergirlstory would be complete without the scene-stealing, super-powered dog Krypto. Jessica Miglio/Warner Bros/DC Studios As of now, there's no official word on whether Corenswet will suit up again as the Man of Steel inSupergirl. We wouldn't be surprised, however, if the actor popped in for a cameo, just like Supergirl did inSuperman. Want more movie news?
