Early impressions from select studio insiders and executives indicate that the new Supergirl film, now under James Gunn supervision, is generating significant positive buzz long before its release. The heightened anticipation follows exclusive screenings held on the Warner Bros. lot, with DC Studios eager to establish a fresh chapter in its on-screen adaptations.
Early Test Screenings: Leak Culture and Industry Secrecy
Test screenings have become vital tools for studios, offering a way to fine-tune upcoming movies. However, public leaks and online spoilers have become almost inevitable, with high-profile cases like recent Superman plot leaks surfacing before scheduled debuts. While Marvel Studios maintains tight secrecy with titles like Spider-Man: Brand New Day and Avengers: Doomsday, DC Studios faces its own challenges in keeping Supergirl’s details under wraps. To date, major public test screenings have not occurred for Supergirl, but trusted insiders and executives have already viewed an initial version.
Positive Early Feedback Fuels Optimism
The excitement was amplified when social media users began sharing remarks from those familiar with these screenings.
“I’ve heard from multiple people in SAG that Supergirl is amazing,”
— @BlackMajikMan90, X user. This was echoed by industry scooper Daniel Richtman who stated,
“I’ve heard the same as well, that the movie is very good.”

Creative Direction Under James Gunn and Cast Highlights
The production team, with James Gunn closely overseeing the project, appears dedicated to capturing the essence of Supergirl as she becomes a pivotal figure in the DC universe following The Superman Saga. Gunn’s involvement has extended to critical decisions such as the casting of Milly Alcock in the lead role, setting expectations high for both fans and industry observers.

Upcoming marketing moves hint at a broader promotional push, with the first trailer slated for release within the next two weeks—potentially sooner, aligning with Supergirl’s planned spotlight at the CCXP event in Brazil. The film’s connection to international fan communities is emphasized through these promotional strategies, helping to generate global excitement.

“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.”

“everybody knows that Jason Momoa is playing Lobo in it…it’s [the Supergirl: Woman of Tomorrow] comic plus Lobo.”
— David Krumholtz, Actor.
