DC’s Girl of Steel Is Almost Here — Everything About the Supergirl Movie 2026

The wait is nearly over. After years of development, casting rumours, and trailer debates, the Supergirl movie 2026 release is just around the corner — hitting screens on 26 June 2026. Directed by Craig Gillespie and headlined by rising star Milly Alcock, this is one of the most talked-about superhero films of the year, and for good reason.

It marks a major step forward in James Gunn’s rebooted DC Universe — and it’s unlike any Supergirl story audiences have seen before.

What Is the Supergirl Movie About?

This isn’t the bright, cape-twirling Supergirl from Saturday morning cartoons. When Gunn announced the project back in 2023, he described the character as “much more hardcore” than previous versions, noting, “She’s not exactly the Supergirl we’re used to seeing.”

The film is adapted from the 2022 comic book series Supergirl: Woman of Tomorrow by Tom King and Bilquis Evely. It takes Kara away from Earth entirely, as she travels through the cosmos with her dog Krypto to escape a life spent perpetually in the shadow of her cousin, Superman.

Along the way, she encounters an alien girl named Ruthye, who is bent on revenge for the death of her father — and recruits Supergirl to help her. It’s part road trip, part revenge quest, and part identity story. Think cosmic scope with genuine emotional weight.

Supergirl 2026 Release Date: When Does It Hit Theatres?

Supergirl hits theatres and IMAX across North America on 26 June 2026, with the international rollout beginning 24 June. The film runs 1 hour 48 minutes and carries a PG-13 rating.

It arrives almost a year after Superman dropped last July, making it the fourth project overall in Chapter One: Gods and Monsters — following Creature Commandos, Superman, and Peacemaker Season 2.

For UK audiences, the Supergirl movie 2026 release is confirmed for the same weekend, giving British fans a chance to see the DCU’s newest hero on the big screen from day one.

Full Cast: Who Stars in Supergirl?

The ensemble assembled for this film is genuinely impressive. Here’s the confirmed lineup:

• Milly Alcock (House of the Dragon) as Kara Zor-El / Supergirl
• Matthias Schoenaerts (The Old Guard) as Krem of the Yellow Hills — the villain
• Eve Ridley (3 Body Problem) as Ruthye Marye Knoll — Kara’s unlikely companion
• David Krumholtz (Oppenheimer) as Zor-El, Supergirl’s father
• Emily Beecham (Into the Badlands) as Alura In-Ze, her mother
• David Corenswet as Clark Kent / Superman — in a brief appearance
• Jason Momoa as Lobo, the intergalactic bounty hunter

Alcock has spoken about how nerve-wracking the audition process was: “They 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.”

Why Jason Momoa as Lobo Is Such a Big Deal

If there’s one casting choice that’s generated the most conversation, it’s Jason Momoa playing Lobo. Momoa enters the DCU not as a hero, but as one of the franchise’s most infamous cosmic threats — an alien bounty hunter known for his brutal methods and darkly comic personality.

Momoa had long wanted to play Lobo, and he initially thought he was being called for the role when DC first offered him Aquaman back in the early DCEU days. After seven years as the King of Atlantis, he was eager to join Gunn’s rebooted DC Universe.

A recent promotional teaser released on 8 June showcases Momoa’s Lobo engaging multiple opponents while laughing menacingly, before delivering the line: “I kill for money, not for sport.” Suffice it to say, the internet lost its mind.

Momoa has hinted that Lobo only has a supporting role in this film, and his future in the DCU depends largely on audience reception. Speaking to ComicBook, Momoa addressed his potential DCU future directly, suggesting the audience would need to “really love him” for the character to continue in the franchise.

Where Does Supergirl Fit in the DC Universe?

This is the second feature film in James Gunn and Peter Safran’s rebooted DC Universe, officially titled Chapter One: Gods and Monsters.

As part of the DCU’s Chapter One, the film is expected to broaden the scope of the franchise beyond Earth-based stories — introducing new extraterrestrial civilisations, interstellar travel, and cosmic conflicts that will likely play significant roles in future DCU projects.

Director Craig Gillespie has compared the movie to Marvel’s Iron Man — not in tone or story, but in terms of its importance as a character-defining origin within a larger cinematic universe. That’s a bold claim, but if Superman (2025) was any indicator, Gunn’s DCU is building something with genuine ambition.

Kara herself was first introduced in Superman last year, so audiences who caught that film will already have a sense of her character before she takes centre stage here.

Behind the Camera: Director and Creative Team

Craig Gillespie directs from a script by Ana Nogueira. Rob Hardy serves as cinematographer, with Claudia Sarne composing the score. The film was produced by James Gunn and Peter Safran through DC Studios, and is distributed by Warner Bros. Pictures.

Filming took place between January and May 2025 at Warner Bros. Studios Leavesden and various locations across London and Scotland.

Gillespie is best known for I, Tonya, Cruella, and Dumb Money — a filmmaker with a genuine instinct for unconventional protagonists and stylised visual storytelling. That sensibility feels like a natural fit for a cosmic revenge story anchored by a woman figuring out who she is outside of Superman’s legacy.
