Supergirl | $68M Global Box Office, Helen Slater Backs Milly Alcock

Supergirl: Woman of Tomorrow, the DC Studios film starring Milly Alcock as Kara Zor-El, opened to $37 million domestically and $68 million globally in its debut weekend, a figure that fell below internal projections and triggered an immediate conversation about DC Studios' ongoing box office reliability. But the film found a vocal champion from an unexpected source: Helen Slater, the actress who first wore the cape in the 1984 original, is urging audiences to hold off on final judgments.

Supergirl Box Office | $37M Domestic, $68M Global Opening Weekend

The opening numbers landed well below what DC Studios co-CEO Peter Safran had modeled internally. Sources close to the production described an internal target of $50M+ domestic for the opening frame, based on tracking data from March 2026 that showed strong awareness among both comic readers and general audiences familiar with Alcock from her breakout role in House of the Dragon.

The $68M global total is consistent with a mid-tier DC release rather than a tentpole. For context, the Super Mario Galaxy Movie opened to $371M globally in April 2026, and Avengers: Doomsday is tracking for a record opening later this summer. Safran publicly acknowledged the debut "fell short of expectations" while describing the film as being in a "wait and see" phase, leaving open the possibility of a strong second-weekend hold if word of mouth from early audiences builds.

Helen Slater on Milly Alcock | "Fierce, Strong, Great Comic Timing"

Slater, now 60, appeared in a round of interviews timed to the film's opening weekend and was unequivocal in her praise. Speaking to The Hollywood Reporter:

"I loved the new Supergirl film. I thought Milly Alcock was astonishing, fierce, strong and great comic timing!"

In earlier comments to People, Slater expanded her endorsement: "It's tapping into something beautiful, irreverent, salty, and gritty." She highlighted the film's framing as a "heroine's journey" and its focus on a young woman navigating emotional trauma as a meaningful evolution of the character's mythology. "Myths must evolve to keep characters breathing," Slater said, "and fresh interpretations are how each new era sees itself reflected in a story."

The 1984 Precedent | Slater Understands the Arc

Slater is uniquely positioned to contextualize a difficult opening weekend. When she starred in the 1984 film at just 18 years old, she completed grueling physical training, including trampolining and fencing, to prepare for the role. She signed a three-picture deal with the production. Despite her commitment and critical acknowledgment of her performance, the 1984 film's modest box office return led the studio to shelve the franchise entirely.

Decades later, the 1984 film has secured a long-term reputation as a cult classic, with home video and streaming viewership consistently outpacing its theatrical performance. Slater pointed to that arc directly when addressing concerns about the new film's opening, noting that a theatrical snapshot taken in week one is rarely the final verdict on a film's cultural lifespan. "Nobody understands that arc better than Helen Slater," noted analysts at Hollywood Outbreak.^[2]

Woman of Tomorrow Source Material | Tom King Comics, Kara Zor-El

The film adapts Tom King's acclaimed 2021 eight-issue DC Comics series Supergirl: Woman of Tomorrow, which reimagines Kara Zor-El not as the bright, optimistic counterpart to Superman but as a more guarded, emotionally scarred character shaped by the destruction of Krypton and the weight of having actually lived through it, a formative difference from her cousin Clark, who was an infant when Krypton died.

The film's central narrative follows Kara on an intergalactic journey alongside a young girl named Ruthye, who is seeking justice for the murder of her father. The "revenge" structure gave Slater a direct line of connection: she described it as a textbook heroine's journey, validating the film's darker, morally complex tone. Critics who have praised the film most strongly have pointed to Kara's ambiguity as its defining strength.

DC Studios Response | Peter Safran on a Challenging Debut

Peter Safran, DC Studios co-CEO alongside James Gunn, addressed the opening in a statement distributed to trade press. He acknowledged the domestic total fell short of the studio's models while expressing confidence in the film's legs. Industry observers note the film earned a strong CinemaScore from audiences who did see it opening weekend, which typically correlates with better second-week holds compared to films that open bigger but land a weaker audience grade.

DC Studios is watching its upcoming film slate closely. The Marvel Avengers: Doomsday release later this summer is expected to draw significant comparison, as both studios are now openly competing for the same superhero-fatigued audience in a year where Netflix's vertical feed and streaming expansion are pulling casual viewers away from theatrical windows entirely.
