‘Supergirl’ Flies Into Theaters With a $100M Marketing Machine and Uncertain Box Office Stakes

When James Gunn launched his rebooted DC Universe last summer with ‘Superman’, the results were a genuine victory lap, a $618 million worldwide haul that gave the new era of DC films exactly the momentum it needed.

One year later, all eyes are back on Warner Bros. as the second entry in Gunn and Peter Safran’s plan arrives in theaters. ‘Supergirl’, directed by Craig Gillespie and starring Milly Alcock as Kara Zor-El, opens Friday in what is shaping up to be one of the most complicated commercial conversations of the summer blockbuster season.

The film is based on Tom King and Bilquis Evely’s acclaimed comic run and follows Kara as she reluctantly teams with Ruthye, a young alien girl seeking vengeance for her father’s death, on a brutal interstellar journey. Joining them is Jason Momoa as Lobo, the alien mercenary and one of the DCU’s most anticipated new additions. The supporting cast also includes Matthias Schoenaerts as villain Krem, with David Corenswet returning as Superman in a cameo role.

On the promotional front, ‘Supergirl’ is arriving with the largest marketing partnership campaign in Warner Bros. DC Studios history. The film has attracted more than 80 sponsors delivering over $100 million in media value, with names such as KFC, Samsung, Ulta Beauty, Waymo, and American Airlines among the partners. KFC in particular built out a full 360-degree campaign, including a collectible Krypto-lidded chicken bucket and a nationwide Intergalactic Rest Stop Tour with a custom-wrapped Airstream.

The goal, according to Warner Bros., is to reach young women and families while building cultural moments beyond the multiplex.

Despite the promotional firepower, box office tracking has told a more cautious story. Analytics firm BoxOfficeTheory revised its domestic opening weekend projection downward by roughly 10 percent in mid-June, landing on a midpoint forecast of $51 million within a range of $47 million to $58 million, while BoxOffice Pro published a similar estimate of $45 million to $55 million.

Both ranges sit uncomfortably close to ‘The Flash’s’ $55 million domestic opening in 2023, a result Warner Bros. has spent years trying to move past. By the final days before release, box office projections had fallen to as low as $40 million, below the previous DC box office disappointment ‘The Flash’.

Part of the problem is the competition. Pixar’s ‘Toy Story 5’ opened the week prior to a massive domestic debut and is projected to remain firmly at the top of the charts on its second weekend, the exact window ‘Supergirl’ is opening into. Barring a major surprise, ‘Supergirl’ appears to be heading for a number two debut behind a Pixar sequel on its second lap. The math behind the film’s profitability is also being closely watched. Deadline reported a net production cost of $175 million, with the film reaching profitability at $315 million in global box office revenue, a lower threshold than the standard industry formula of 2.5 times the budget would suggest.

The first reactions to ‘Supergirl’ landed last week and landed in two very distinct camps, though one area produced something close to a consensus. Milly Alcock’s performance has been praised almost universally by early viewers. Den of Geek’s David Crow said she “absolutely owns the role and will change our idea of Supergirl forever,” while Total Film’s Fay Watson called her “perfect, bringing humour, heart, and incredible drunk acting.” Momoa’s Lobo has been another consistent standout, with multiple critics describing him as a blast and the film’s most energetic presence.

The film itself, however, has been more divisive. Germain Lussier, writing for Gizmodo and io9, called the movie “highly enjoyable” and praised it as “a perfect companion and follow-up to Superman with better characters and more complex relationships,” but noted it “doesn’t quite have the resonance of Superman.” Others were more measured. The recurring complaint across mixed reactions is the villain, with Schoenaerts’ Krem described as underwhelming, and some reviewers noting structural issues with the screenplay.

One element of the early reactions that has genuinely surprised people is the film’s tone. ‘Supergirl’ is not the bright, hopeful cosmic adventure some expected. Multiple critics described the film as playing more like ‘Mad Max’ than ‘Guardians of the Galaxy’, with dirty worlds, a self-destructive heroine, and an unexpectedly grimy atmosphere. That tonal gamble is either the film’s greatest strength or its clearest commercial risk, depending on who you ask.

What is not in question is Alcock’s future in the DCU. She is already confirmed to reprise the role in the upcoming ‘Man of Tomorrow’, and DC Studios co-CEO Peter Safran has publicly stated that her Supergirl will play a major role in the universe going forward. The opening weekend may not be the definitive verdict on whether DC’s second chapter succeeds, but it will be the loudest data point the industry has had to work with since ‘Superman’ made this whole experiment feel possible.
