The Supergirl secrets keep coming, and this one is worth paying attention to. There is a lot riding on Supergirl heading into the summer, and not just because it’s the first major superhero outing of 2026. It’s also the next proving ground for the DCU being rebuilt by James Gunn and Peter Safran and, in a notable first, the debut of a big screen DCU project that Gunn neither wrote nor directed. Director Craig Gillespie has now shed some light on key Supergirl story details, including how long the film actually runs and what he will and won’t say about what happens after the credits.
Supergirl Duration Confirmed: Here’s How Long the Film Runs
Fresh Supergirl updates from Craig Gillespie confirm that the Supergirl running time clocks in at just under one hour and fifty minutes with credits included, per ComicBookMovie.com via Collider. That puts the Supergirl length noticeably below Superman, which came in just north of two hours. The slimmer Supergirl film length suggests a more focused, efficient story, which honestly makes sense given where DC Studios is in the process of building out this universe. Getting the tone right matters more right now than going big for the sake of it. Trailer reactions have been mostly warm, though some fans have flagged tonal echoes of Guardians of the Galaxy, which has sparked some back and forth about how much of Gunn‘s influence carries over even when he’s not in the director’s chair.
Supergirl Post Credits Scene: The Director Isn’t Talking
The Supergirl post credits question is basically a rite of passage at this point, and Craig Gillespie was asked about it directly. His answer was brief and predictably tight-lipped: “I can’t tease that, sorry.” A Supergirl stinger of some kind feels like a near certainty given how DC Studios has been operating, and the leading theory right now is that it will lay groundwork for Man of Tomorrow, the expected Milly Alcock follow-up that would build on what Superman started. The Supergirl end credits scene speculation is running hot, and it won’t slow down until opening night.
Jason Momoa’s Lobo and What It Means for the DCU
One of the bigger Supergirl secrets to surface behind the scenes involves Jason Momoa and what his appearance in the film might actually signal. Peter Safran has spoken openly about Momoa‘s passion for playing Lobo, sharing that the actor was lobbying for the role even during his Aquaman days. Reportedly, the moment DC Studios leadership was announced, Momoa fired off a message that was just the word “LOBO” in all caps and nothing but exclamation points after it. “It’s so great to have an actor who is such a volunteer and not a recruit,” Safran said. The hope among fans is that Supergirl plants the seed for a full Lobo solo project down the line, and based on everything Safran has described, that trajectory seems very much in play.
Supergirl Cast: Milly Alcock and the Full Lineup
Milly Alcock leads Supergirl as Kara Zor-El, joined by Matthias Schoenaerts, Eve Ridley, David Krumholtz, Emily Beecham, and Jason Momoa. The story follows Kara on an interstellar mission fueled by personal loss and a drive for justice, with an unlikely partnership forming along the way. Craig Gillespie directs from Ana Nogueira‘s script, with the film scheduled to open June 26.
Why ‘Supergirl’ Is One of the Summer’s Most Important Releases
More Supergirl secrets are sure to surface as June 26 draws closer, but the film insights that have trickled out so far already paint a picture of a project with real stakes attached to it. Coming in the wake of Superman‘s strong reception, Supergirl has an opportunity to prove that this version of the DCU isn’t a one-filmmaker show. With Craig Gillespie steering the ship and Ana Nogueira handling the script, the film brings a fresh set of voices into a universe that still has everything to prove. If it connects, DC Studios has its blueprint. If it doesn’t, the questions come fast.
Supergirl opens June 26 and the industry will be watching every number closely.
