James Gunn Addresses Milly Alcock Supergirl Firing Rumors and DCU Scandals
Rumors about Milly Alcock’s role as Supergirl spread rapidly through the fandom this week. As the actress began to remove certain Supergirl-related posts from her social media, speculation surged regarding the future of Kara Zor-El in the DC Universe.
The timing of these concerns felt justified. Alcock’s standalone film, ‘Supergirl’, premiered on June 26 under director Craig Gillespie, earning approximately $37 million to $38 million in North America, and concluding its run with around $126 million globally. These figures led to discussions about the film’s performance, adding pressure to subsequent DCU news.
The rumors intensified on Thursday when fans observed Alcock had deleted Supergirl content from her Instagram, including her casting announcement from January 2024. While some photos and Reels remain visible, the deletions fueled speculation that something had gone awry behind the scenes.
At that point, no official confirmation had emerged. No media outlet reported a firing, and neither Alcock nor DC Studios had made any statements. Videos claiming her dismissal had been circulating on YouTube since the summer, making the Instagram changes seem like fresh evidence.
On Friday, James Gunn took to Threads to respond directly to the rumors. A fan had listed three claims they labeled as fake news regarding the DCU: that Matt Reeves was off ‘The Batman Part II’, that Alcock had been fired as Supergirl, and that ‘Man of Tomorrow’ had a poorly received test screening due to a dark ending and the death of a beloved hero.
Gunn’s response was straightforward. He urged fans to disregard the misinformation, stated he was mostly done debunking rumors due to their volume, and confirmed that all three claims were completely false. This marked the first official word from DC regarding Alcock’s situation, delivering a clear denial.
Gunn’s explanation dismantled the ‘Man of Tomorrow’ rumor. He mentioned he was showing Peter Safran his first Director’s Cut that very day, with Safran being the first to view it, and that it would arrive a month early. Thus, there was no completed version available for any test screening.
This detail is crucial since the darker tone suggested in the rumor didn’t come from nowhere. Reports have indicated that the sequel is more intense than Gunn’s typical style, with David Corenswet likening it to ‘The Empire Strikes Back’. However, a grim test screening never occurred.
The rumor about ‘Batman Part II’ also had its own backstory. Recent news revealed that Steven Soderbergh is wrapping up filming while Reeves attends to a family matter, which quickly morphed into speculation about the director departing. Reeves has confirmed he is not leaving the project and will return for post-production, with Gunn having already addressed the rumor earlier in the week.
Together, these denials provided the DCU with a rare moment of clarity. For a franchise that has faced ongoing speculation, Gunn’s single response managed to quell three separate controversies.
Gunn’s statement aligns with the studio’s previous assertions. Alcock is confirmed to reprise her role as Supergirl in ‘Man of Tomorrow’, which is currently filming in Atlanta and is set to hit theaters on July 9, 2027. DC Studios co-CEO Peter Safran has also stated that she plays a significant role in the studio’s upcoming projects.
The sequel is shaping up to be a collaborative story, featuring David Corenswet’s Superman alongside Nicholas Hoult’s Lex Luthor, with Brainiac as the primary antagonist. Additionally, Aaron Pierre is set to introduce John Stewart to the big screen after his debut in the HBO Max series ‘Lanterns’. Alcock is firmly part of this impressive lineup.
The final trailer for ‘SUPERGIRL’ has been released.

Despite the denials, Alcock has yet to comment on her Instagram, and Gunn has not addressed the deletions either. Fans may understandably question the removal of posts, but the firing theory now faces a strong counterargument from the leadership of DC Studios.
For a studio that has recently transitioned under Skydance, with Gunn and Safran remaining at the helm, this kind of clear communication is beneficial. It highlights how quickly a single deleted post can escalate, especially following a film’s underperformance. For now, Kara Zor-El seems to be exactly where she is meant to be.
