Supergirl actress Milly Alcock has reportedly removed nearly every post associated with her DC Studios movie from her Instagram grid, including the original announcement celebrating her casting as Kara Zor-El. The unexpected social media cleanup comes months after the film suffered a disastrous theatrical run, prompting speculation about her future in James Gunn’s DC Universe.
According to ComingSoon, fans noticed on October 15 that Alcock had removed numerous photographs and promotional materials associated with Supergirl, including images of herself in costume and her January 2024 casting announcement.
That original announcement was particularly noteworthy because Alcock personally thanked Gunn for giving her the opportunity to portray the iconic DC Comics character.
The now-removed post read: “So excited to be a part of the DC fam, thank you so much to @jamesgunn for trusting me with Kara / Supergirl.”
A photograph featuring Alcock holding a copy of Tom King’s Supergirl: Woman of Tomorrow, the comic book that inspired her standalone film, has also disappeared.
However, Alcock has not completely erased the character from her social media presence. Several Supergirl-related videos remain in her Instagram Reels section, alongside a Vogue promotional post associated with the film.
Neither Alcock nor DC Studios has publicly explained the removals.
Supergirl’s Disastrous Box Office Performance
The timing is particularly interesting considering the financial disappointment surrounding Supergirl.
Directed by Craig Gillespie and produced under Gunn and Peter Safran’s leadership, the film was intended to establish Alcock’s Kara Zor-El as another major character in DC Studios’ rebooted cinematic universe.
Instead, the movie struggled to attract audiences.
According to Box Office Mojo, Supergirl earned approximately $126.4 million worldwide against a reported production budget of $170 million to $180 million.

That means the film failed to generate enough worldwide ticket sales to equal its production budget, even before accounting for marketing expenses and the portion of theatrical revenue retained by exhibitors.
DC Studios co-CEO Peter Safran subsequently acknowledged the disappointing results.
“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,” Safran stated.
The disappointment followed Gunn’s Superman, which generated approximately $618.7 million worldwide but also faced questions about its profitability. As That Park Place previously reported, Netflix co-CEO Ted Sarandos identified Superman as an underperforming theatrical release during February 2026 Senate testimony.
A separate financial analysis had estimated that the film lost approximately $42 million, although that figure was not confirmed by Warner Bros.
With Supergirl performing substantially worse, questions surrounding the financial viability of Gunn’s DC Universe have only intensified.
Is Milly Alcock Finished Playing Supergirl?
Naturally, Alcock’s Instagram activity has generated speculation that she could be distancing herself from the franchise.
The development also comes shortly after Paramount-Skydance completed its acquisition of Warner Bros. on October 6, placing DC Studios under new corporate ownership.
However, there is currently no verified evidence that Alcock has been fired or that DC Studios intends to recast Supergirl.
In fact, Alcock is expected to reprise her role in Gunn’s upcoming Superman sequel, Man of Tomorrow, scheduled for July 9, 2027.

Supergirl producer Lars P. Winther confirmed Alcock’s involvement in the sequel.
“Man of Tomorrow, which is what we’re shooting now, [Alcock] is in that movie,” Winther explained.
He also suggested that the character would play an important role in another upcoming DC project.
Additionally, ComicBook.com noted that Alcock previously cleaned up her Instagram account following her involvement with HBO’s House of the Dragon.
That raises the possibility that the actress is simply managing her social media presence rather than signaling dissatisfaction with DC Studios. Promotional obligations can also expire, allowing performers to remove advertising materials after completing contractual commitments.
Neither explanation has been confirmed in Alcock’s case.
Another Question Mark for James Gunn’s DC Universe
Regardless of Alcock’s intentions, the removals arrive at an uncomfortable moment for DC Studios.
With Supergirl suffering a substantial financial disappointment, Lanterns generating controversy among longtime Green Lantern fans, and Warner Bros. operating under new ownership, the franchise faces increasing scrutiny.
The disappearance of Alcock’s original casting announcement is particularly striking because it represented one of the earliest public celebrations of Gunn’s rebooted cinematic universe.
Removing that announcement does not establish that Alcock regrets accepting the role or intends to leave the franchise.
Nevertheless, the timing has understandably attracted attention.

For now, Alcock remains associated with Supergirl, and her upcoming appearance in Man of Tomorrow has not been canceled.
Whether her Instagram cleanup represents ordinary social media housekeeping or something more significant remains an unanswered question.
And following Supergirl‘s disappointing box office performance, it’s a question DC Studios probably would have preferred not to face.
