Supergirl, the DC Studios film opening June 26 with Milly Alcock as Kara Zor-El and Craig Gillespie directing from a Tom King-adapted script, is tracking for a $47 million-to-$65 million domestic opening weekend, by Forbes’s box-office desk’s mid-range projection of $55 million. The result, if it lands inside the bottom half of that window, would mark the first significant test of James Gunn’s DC Universe-rebuild momentum since David Corenswet’s Superman opened to $125 million domestic in July 2025.
The tracking is unusually transparent for a Warner Bros. release of this profile, with multiple Forbes-and-Cosmic-Book-News data points landing inside an unusually narrow window. Forbes reported the film’s pre-release awareness scores are tracking 22 percent below Superman’s at the same pre-release date, while interest-and-favorability are tracking 14 percent and 8 percent below respectively, the kind of indicator pattern that historically correlates with a 30-to-35 percent lower opening weekend.
Cosmic Book News reported Warner Bros.’s in-house marketing team had been showing executives a $72 million central-case opening as recently as April, with the post-trailer-and-CinemaCon projections being walked down across May and into the early June pre-release window. The studio’s official PR-side stance has remained that Supergirl is positioned for a strong four-quad opening, but tracking analysts have moved their consensus to the lower band of the original forecast.
The June 26 release date itself is part of the difficulty. Supergirl opens four weeks behind Steven Spielberg’s Disclosure Day, three weeks behind Pixar’s Toy Story 5, and on the same weekend as a second-weekend hold from The Mandalorian and Grogu, per our box-office dispatch. The summer corridor has been the most-crowded of any since 2019, and tracking analysts have been treating Supergirl as the title most at risk of being squeezed by the surrounding event films.
For DC Studios, the result will be more important than the raw number. Gunn’s two-year-old rebuild project has so far relied on Superman as the singular commercial proof of concept; Peacemaker Season 2 on HBO Max has been the television-side analog. Supergirl is the first theatrical follow-up under the new umbrella, and the tracking shape is being read as a signal about how broadly the Gunn-era DCU will be received by the audience that has, by Nielsen survey data, become more demographically diverse over the last two years.
Alcock, the Australian actress who broke out as the young Rhaenyra Targaryen in House of the Dragon Season 1, has been the central marketing engine of the rollout, with a June press cycle that included a Tom Hanks-style Vanity Fair cover-story positioning, a six-city European premiere tour, and the obligatory Letterman-and-Kimmel late-night booking sweep. The Movie Blog reported her press-cycle availability was nearly twice as long as Corenswet’s had been ahead of Superman, but the corresponding interest-tracking lift has not materialized.
Gillespie, whose Cruella opened to $26 million in pandemic-window 2021 and whose Dumb Money grossed roughly $26 million theatrically, has been the production’s quieter creative center. The Supergirl script, which Tom King adapted from his comic-book run, leans into the character’s Krypton-and-Argo City origin and pivots the structural setup away from the female-led Earth-arrival template that the original 1984 Helen Slater Supergirl used. King has been credited as a producer through the production cycle.
The release also lands inside Hollywood’s broader 2026 mid-budget-blockbuster pattern. Tom Hanks’s Toy Story 5 premiere, where his marriage-advice line about “making the waffles on Sunday” went viral, sits as the same cycle’s softer-press analog per our coverage. Industry trackers are reading Supergirl’s tracking pattern as a stress test for the broader pre-July-Fourth release-window strategy that studios have been refining.
Warner Bros.’s commercial-PR position on Supergirl is expected to harden through the next two weeks. The studio’s marketing team has been adding TikTok-and-Instagram-Reels micro-spots into the rollout pattern through the past 10 days, a shift from the more-traditional television-buy-heavy approach that Superman used. The film’s worldwide opening on June 26 will be its first definitive read; full international-and-domestic actuals are expected the Monday after.
