James Gunn supervises Supergirl movie as Warner Bros. aims for a standout entry in DC Studios’ evolving lineup, with early private screenings on the studio lot generating buzz ahead of its 2026 release. With select executives and insiders recently viewing the first cut, initial reactions suggest that this latest chapter in the Superman saga could earn strong support from fans and industry insiders alike.
Social Media and Leaks Shape Public Perception
Studio-led test screenings have become an industry standard for major releases, but in an era where social media spreads information instantly, details about upcoming films often escape early. Before its July debut, Superman’s entire plot was leaked, raising concerns that Supergirl might encounter similar issues, especially as DC Studios continues refining its filmmaking process. Marvel Studios, facing its own challenges, has reportedly implemented tighter holds on information for its high-profile projects.
Private Screenings Spark Positive Speculation
While screenings for general audiences have not occurred, credible trades have reported that an early cut of Supergirl was shared with Warner Bros. executives and a selected group of insiders. News quickly made its way onto social platforms.
“I’ve heard from multiple people in SAG that Supergirl is amazing,”
– @BlackMajikMan90, Social Media User
“I’ve heard the same as well, that the movie is very good.”
– Daniel Richtman, Industry Scooper
Another attendee contributed,
“I know someone who was at a test screening, he said it had a very positive reception and foresees the movie being very well received.”

The overall mood points to optimism, building momentum ahead of any global public preview.

Adhering to Comic Roots and Introducing Key Characters
David Krumholtz, part of the Supergirl cast, provided insight into how closely the movie tracks the source material, saying,
“It’s very true to the graphic novel that it’s based on, Woman of Tomorrow,”
and,
“Which is great. I’m thrilled to be sort of the next piece of telling the story of Krypton and sort of further clarifying what the House of El is all about.”
– David Krumholtz, Actor
He further commented on the ensemble and characters, noting,
“everybody knows that Jason Momoa is playing Lobo in it…it’s [the Supergirl: Woman of Tomorrow] comic plus Lobo.”
– David Krumholtz, Actor
The story follows Supergirl, portrayed by Milly Alcock, as she journeys across the galaxy with Krypto the Superdog to celebrate her 21st birthday. Along the way, she meets Ruthye, a new character, and is drawn into a quest for vengeance. The supporting cast includes Eve Ridley as Ruthye Marye Knoll, Matthias Schoenaerts taking the role of Krem of the Yellow Hills, Jason Momoa embodying Lobo, Emily Beecham as Alura In-Ze, Ferdinand Kingsley appearing as Elias Knoll, and David Krumholtz taking on Zor-El. Direction comes from Craig Gillespie, with Ana Nogueira crafting the screenplay.
Upcoming Trailer and Anticipation for Release
Fans are awaiting the film’s first official trailer, rumored for an imminent launch, with an expected debut at the next CCXP event in Brazil. As marketing efforts increase, expectations are that Warner Bros. and DC Studios will try to minimize spoilers, learning from earlier leaks across the superhero genre. The carefully coordinated promotion is expected to intensify as the June 26, 2026, theatrical release date of Supergirl draws closer. With strong creative oversight, early acclaim from insiders, and a cast that bridges new and familiar faces, this film is positioned to be a major chapter in the ever-evolving DC Universe.
Just because you live in Burbank doesn’t mean you know anything.
