Supergirl 2026 Movie Leak: Milly Alcock’s Suit, & Lobo Cameo?

The buzz around the Supergirl 2026 movie is only growing louder, especially after new details surfaced about its story, tone, and surprising cameos. With DC Studios completely rebooting its cinematic universe under the guidance of James Gunn and Peter Safran, this upcoming Supergirl film isn’t just another spin-off it could be a total game-changer.

What Is the Supergirl 2026 Movie All About?

The Supergirl 2026 movie, officially titled Supergirl: Woman of Tomorrow, is based on the comic series by Tom King and Bilquis Evely. Unlike past versions, this Supergirl isn’t all sunshine and hope. She grew up on a broken chunk of Krypton, watching people suffer and die. James Gunn called her the “hardened” cousin of Superman , and yeah, she’s seen way more trauma than Clark Kent ever did.

Milly Alcock, best known for playing young Rhaenyra in House of the Dragon, will take on the role of Kara Zor-El. And honestly, fans think she’s a perfect fit edgy, emotionally raw, and totally believable as a space-born warrior.

Shooting Wrapped, but the Hype Is Just Starting

Filming for the Supergirl 2026 movie wrapped in May 2025, with most scenes shot at Leavesden Studios in the UK. There were also on-location shoots in Iceland and parts of rural Scotland possibly for the film’s alien landscapes. Some leaked set images showed Kara walking across desolate plains with a sword on her back. These are unconfirmed leaks, but they were widely shared on Twitter (X) and reposted by fan accounts with thousands of followers.

The Story: Grittier Than You Think

This isn’t the bubbly, cheerleader-style Supergirl we’ve seen before. In this new take, Kara is on a space revenge mission. The story begins when she meets Ruthye, a young alien girl whose father was killed by a war criminal named Krem of the Yellow Hills. Together, they travel across strange worlds to hunt him down.

The film will feature Krypto the Superdog, alien bar fights, emotional breakdowns, and yes at least one Lobo cameo.

Jason Momoa Is (Probably) Lobo

One of the biggest Supergirl 2026 movie rumors floating around is that Jason Momoa is playing Lobo, the intergalactic bounty hunter. James Gunn did confirm Momoa filmed something for the DCU in 2025, and while many assumed it was for a future Lobo solo project, several insiders say it’s actually a Supergirl appearance.

This hasn’t been confirmed by DC or Gunn, so for now, chalk it up as a very strong rumor but from usually reliable sources like @MyTimeToShineHello on Twitter.

The Team Behind It

Here’s what we know for sure:

Director: Craig Gillespie (I, Tonya, Cruella)

Writer: Ana Nogueira (known for strong emotional character work)

Lead Cast:

Milly Alcock as Kara Zor-El

Eve Ridley as Ruthye

Matthias Schoenaerts as Krem

Emily Beecham & David Krumholtz as Alura and Zor-El

Gillespie’s style usually mixes dark humor with raw emotion, which sounds perfect for a character-driven sci-fi drama like this.

A Darker Side of the DC Universe

The Supergirl 2026 movie is the second major installment in James Gunn’s Chapter One: Gods and Monsters. It follows Superman (2025) and offers a totally different vibe. Where Clark Kent’s story is expected to be inspiring and bright, Kara’s journey looks to be sadder, harsher, and more personal.

Gunn even said, “Superman was raised on Earth with love. Supergirl watched everyone around her die. She’s angry, she’s not soft, and she’s gonna show it.”

Fan Response and What’s Next

DC fans seem split. Some miss the CW-style bright Supergirl, but many are praising this bold new approach. After the recent DCU misfires, people are cautiously optimistic. Alcock’s fan art is everywhere, and hashtags like #Supergirl2026 and #MillyAlcockSupergirl have been trending multiple times.

So when’s the trailer coming? Based on DC’s marketing style, we’ll probably get the first teaser after Superman (2025) drops. Some insiders are even betting on a Comic-Con 2025 reveal but again, that’s just speculation for now.

Final Thoughts: Why This Film Might Actually Matter

There’s a lot riding on the Supergirl 2026 movie. It’s not just about introducing Kara it’s about showing fans that the DCU can handle tone. From interplanetary fights to quiet grief, this film might give us one of the most layered female leads in superhero cinema.

If they get this right, Supergirl won’t just be Superman’s cousin anymore. She’ll be the main character.
