DC Studios co-CEO James Gunn has publicly denied rumors that Milly Alcock was fired from her role as Supergirl following the disappointing box office performance of her standalone film. However, his response leaves unanswered questions about the actress’s decision to remove several Supergirl-related posts from her Instagram account.

The speculation began circulating after fans discovered that Alcock had deleted multiple promotional posts associated with the movie, including her original casting announcement. Given the film’s commercial struggles and the recent change in Warner Bros.’ ownership, the deletions fueled speculation that her future in the DC Universe might be uncertain.

Gunn has now addressed those rumors directly, insisting that reports of Alcock’s dismissal are false.

James Gunn Denies Milly Alcock Firing Rumors

Gunn responded to the speculation on Threads on October 16.

The filmmaker was addressing three separate claims involving DC Studios: that Alcock had been fired as Supergirl, that Steven Soderbergh had replaced Matt Reeves as director of The Batman Part II, and that Man of Tomorrow had received negative reactions during early screenings.

Gunn wrote: “Oh brother. You guys just have to stop listening to BS, and I’m mostly done shooting down rumors as there are so many and I’m not on here much. But all three of these couldn’t be more false.”

His response represents the clearest public denial yet that Alcock has been dismissed from the franchise. However, Gunn did not announce another standalone Supergirl film or provide additional details about why Alcock wiped a series of Supergirl posts from her social media.

Why Did Milly Alcock Delete Her Supergirl Instagram Posts?

Although Gunn’s statement addresses the firing rumors, it does not explain the social media activity that helped fuel them.

Alcock reportedly removed several Instagram posts promoting Supergirl, including material celebrating her casting as Kara Zor-El.

The timing attracted particular attention because the deletions followed the movie’s disappointing theatrical performance.

If Alcock remains attached to the character, and DC Studios intends to continue featuring her version of Supergirl, why remove promotional material associated with one of the most significant roles of her career?

There are several possible explanations.

The actress could simply have been reorganizing her social media account. She may also have personal reasons for removing older promotional material unrelated to her professional relationship with DC Studios. It could also stand to reason that she doesn’t want to be so publicly associated with one of the biggest theatrical bombs of the year.

ComicBookMovie previously reported that Alcock had not completely erased Supergirl from her Instagram account and had previously removed posts associated with other projects.

Nevertheless, the decision raises questions that Gunn’s denial doesn’t resolve.

Was Alcock dissatisfied with the reception to the film? Was she simply moving on from its promotional campaign? Or was there another reason for removing the posts?

There is currently no verified evidence connecting the deletions to a disagreement with DC Studios or a change in Alcock’s employment status.

Until the actress explains the decision herself, the motivation remains unknown.

Supergirl’s Box Office Failure Complicates Its Future

The speculation surrounding Alcock can’t be separated from the financial performance of Supergirl.

The film earned approximately $126 million worldwide against a production budget of roughly $180 million.

That theatrical performance represents a substantial commercial disappointment, particularly when additional marketing and distribution expenses are considered.

While Gunn has denied that Alcock was fired, retaining an actress in a franchise doesn’t necessarily mean the studio intends to produce another expensive standalone movie featuring her character.

DC Studios could continue featuring Alcock’s Supergirl in ensemble productions, crossover appearances, or supporting roles without committing to another solo film.

The distinction becomes particularly relevant following Skydance’s acquisition of Warner Bros., which places the DC Universe under the oversight of David Ellison’s new leadership.

Gunn has previously discussed Ellison’s familiarity with the studio’s creative plans, stating: “David knows everything. We told David long ago, and went through what the basic plan was.”

However, knowledge of an existing creative roadmap does not necessarily guarantee that every proposed project will receive financing.

Gunn Also Rejects Man of Tomorrow and Batman Rumors

Gunn’s response extended beyond Alcock’s future.

The filmmaker also denied reports suggesting that Man of Tomorrow, his upcoming sequel to 2025’s Superman, had received negative reactions during early screenings.

He explained: “I’m showing PETER SAFRAN my first Director’s Cut today – he’s the first person to see it obviously – and that’s a month early!”

According to Gunn, Safran was scheduled to become the first person to view the director’s cut on October 16, directly contradicting claims that test audiences had already screened the movie.

Gunn also rejected speculation that Steven Soderbergh had replaced Matt Reeves as director of The Batman Part II. Soderbergh is simply stepping in to finish principle photography why Reeves attends to a family matter.

Both denials arrive as DC Studios faces increased scrutiny over its upcoming theatrical slate and the direction of the franchise under Warner Bros.’ new ownership.

Milly Alcock Remains Supergirl but Her Next Appearance Is Unclear

For now, Gunn’s position is unequivocal: Milly Alcock has not been fired as Supergirl.

That clarification is significant and should put an end to claims presenting her dismissal as an established fact.

However, it does not answer every question surrounding the actress’s future.

Alcock has not publicly explained the Instagram deletions, Gunn has not announced another standalone Supergirl movie, and the film’s disappointing financial performance remains a challenge for the franchise.

The actress could continue portraying Kara Zor-El in future DC Universe productions without receiving another solo outing.

Ultimately, Gunn’s denial confirms that Alcock has not been dismissed, but it does not establish what DC Studios intends to do with Supergirl moving forward.

Until additional details emerge, the mystery surrounding her deleted Instagram posts and the character’s long-term future remains unresolved.
