Supergirl has been hit by a brutal box office collapse just days after landing in cinemas, with the Milly Alcock-led DC film reportedly plunging by as much as 80% in Friday-to-Friday business during its second weekend. The sharp fall came after the superhero movie opened to $37.1 million domestically, a soft start for a blockbuster carrying a reported $170 million production budget.
The Craig Gillespie-directed film, starring House of the Dragon breakout Alcock as Kara Zor-El, has also become a flashpoint online after one viewer reaction claimed: 'First time I've seen people walk out of theatres in a while.' While the walkout claim remains an individual social media reaction rather than a confirmed audience trend, it has fed into a wider conversation about weak word of mouth, superhero fatigue and whether DC Studios' reboot is struggling to keep casual viewers invested.
Supergirl's Second Weekend Slide Sparks Fresh DC Panic
According to box office tracking data, Supergirl opened in 3,602 domestic theatres and earned $37,102,018 in its first weekend. By its second frame, the film's domestic total stood at $57,472,071, meaning the movie had not built the kind of legs usually needed for a costly studio release. Its worldwide total was listed at roughly 0.6 times its production budget, before marketing costs are even considered.
The drop is especially damaging because Supergirl was not positioned as a minor spin-off. It is part of DC Studios' new cinematic universe under James Gunn and Peter Safran, following David Corenswet's Superman and setting up a broader slate of interconnected films. Alcock's Kara had already been introduced to audiences through Superman, giving the solo film a clear runway into the revamped DCU.
The film's premise also carried obvious fan appeal. Kara Zor-El travels across the galaxy with Krypto before being pulled into a mission of vengeance and justice, a darker contrast to Superman's more hopeful mythology. Gunn previously described this version of Supergirl as someone with 'edge, grace [and] authenticity', a sign that DC was deliberately moving away from a cleaner, more traditional version of the character.
Walkout Claims Add to the Word-of-Mouth Problem
The viral walkout comment landed because it matched the mood around the film's commercial performance. Online discussion has been split between viewers defending Alcock's performance and others calling the film underwhelming, but the box office numbers suggest the movie failed to convert curiosity into repeat business. For a superhero release, that is a major problem because second-weekend hold often reveals whether fans are recommending it beyond opening-night crowds.
The response also shows how quickly online reactions can shape a film's public image. A single theatre anecdote can travel faster than a formal review, especially when it fits an existing narrative about a blockbuster in trouble. Meanwhile, Supergirl defenders argued that a female-led superhero film was being judged more harshly than similar franchise entries.
DC Studios has already acknowledged that the film did not land as hoped. Safran said: 'While Supergirl didn't meet our box office expectations, it's just one component of a broader, long-term strategy at DC Studios that we remain confident in.' That statement keeps the studio's bigger plan intact, but it also confirms that the film's early performance missed internal targets.
Milly Alcock's DC Future Faces Tougher Road
For Alcock, the commercial stumble comes at a complicated moment. The Australian actress became a major name through House of the Dragon, where her performance as young Rhaenyra Targaryen helped make her one of the fantasy genre's most-watched rising stars. Supergirl was meant to push her into full blockbuster lead territory, but the film's box office story has so far overshadowed her performance.
That does not necessarily mean the character is finished. DC's new slate still has room to reposition Kara, especially if future films use her alongside more established characters such as Superman, Batman or Wonder Woman. The bigger challenge is whether audiences still want mid-tier superhero solo films when streaming waits are shorter, tickets are expensive and franchise loyalty is no longer automatic.
For now, Supergirl has become less of a clean victory lap for DC's reboot and more of a warning sign. The film had a recognisable heroine, a rising lead, Krypto, a space adventure hook and a major studio push, yet still suffered a punishing collapse. Whether the walkout claim reflects a wider audience mood or simply one brutal viral reaction, the numbers show that Supergirl has not flown as high as DC needed.
