In a development that has stirred fresh controversy in the DC Universe fandom, Ezra Miller, known for their role as The Flash in the now-defunct DC Extended Universe (DCEU), recently posted a disparaging remark on X about David Corenswet and James Gunn’s upcoming Superman film, set to release on July 11, 2025. The post, which was quickly deleted but widely screenshotted and shared across X, has reignited debates about Miller’s tumultuous relationship with Hollywood and the evolving DC Universe under Gunn’s leadership. The incident comes at a time when Miller is attempting a tentative return to acting following a series of legal and personal controversies, adding fuel to an already polarized discussion about their career and the future of DC’s cinematic landscape.

Miller’s post, described by users on X as a cryptic jab, reportedly mocked Corenswet’s casting as Superman and questioned Gunn’s vision for the rebooted DC Universe (DCU). While the exact wording remains unverified due to the post’s swift deletion, X users quoted it as implying that Corenswet’s portrayal would lack the gravitas of previous Superman actors like Henry Cavill, and that Gunn’s lighter, more hopeful tone was a misstep for the iconic character. The backlash was immediate, with fans of the new DCU rallying to defend Corenswet and Gunn, whose Superman is being positioned as a fresh start after the mixed reception of the DCEU. One X user wrote, “Ezra’s out here throwing shade while their own Flash movie tanked. Maybe sit this one out.” Others, however, expressed sympathy for Miller, suggesting their frustrations stem from being sidelined as the DCU moves forward without them.

The context of Miller’s post is critical. The Flash, released in 2023, was a commercial and critical disappointment, grossing only $223 million against a reported $200 million budget, marking the end of Miller’s tenure as the Scarlet Speedster. James Gunn, now co-CEO of DC Studios, has confirmed that The Flash will not continue in the new DCU, with speculation swirling about a potential gender-swapped Flash or a new actor taking the role. Miller’s career has been further complicated by a string of legal issues in 2022, including arrests and allegations of harassment, which led to a period of retreat from the public eye. Their recent appearances, including a Cannes cameo in 2025 and talks of a new project with director Lynne Ramsay, signal an attempt to rebuild their career, but the disparaging post has raised questions about their judgment and timing.

The Superman film, directed by Gunn and starring Corenswet as Clark Kent, is generating significant buzz as the DCU’s first major theatrical release. Early screenings have garnered positive reactions, with critics praising Corenswet’s “gentle nerdiness” and Gunn’s blend of action, humor, and heart. The cast, including Rachel Brosnahan as Lois Lane and Nicholas Hoult as Lex Luthor, has been lauded for its chemistry, and the film’s fresh take—rooted in comics like All-Star Superman—aims to distinguish it from the darker DCEU era. Miller’s post, however, has drawn attention away from this momentum, with some fans accusing them of sour grapes. “Ezra had their shot, and it didn’t work out,” one X user commented. “Dragging Corenswet and Gunn won’t change that.”

The incident highlights broader tensions within the DC fandom as it transitions from the DCEU to the DCU. While some mourn the loss of actors like Henry Cavill, who played Superman in the DCEU, others are eager for Gunn’s vision to redefine the franchise. Miller’s post has also sparked discussions about the role of social media in amplifying celebrity feuds, with X serving as a battleground for fans and detractors alike. Supporters of Miller argue that their frustrations are understandable, given their exclusion from the DCU and the intense scrutiny they’ve faced. Critics, however, see the post as unprofessional, especially given Gunn’s past support for Miller during The Flash’s troubled production, with the director calling it “one of the greatest superhero movies” in 2023.

As the July 11 release of Superman approaches, the controversy surrounding Miller’s post is unlikely to derail the film’s momentum, given its strong early buzz and Gunn’s proven track record with films like Guardians of the Galaxy. For Miller, however, the incident risks further alienating fans and industry peers at a critical juncture in their comeback. The DCU’s future, with projects like The Brave and the Bold and a Wonder Woman reboot in development, is moving forward without Miller, and their recent actions suggest a struggle to reconcile with that reality. For now, the spotlight remains on Corenswet and Gunn, whose Superman is poised to redefine the Man of Steel for a new generation, while Miller’s post serves as a reminder of the challenges of navigating fame, fandom, and redemption in the ever-evolving world of superhero cinema.
