The upcoming Superman film, directed by James Gunn and set to release in July 2025, has already sparked plenty of buzz, not least because of a curious behind-the-scenes debate about the Man of Steel’s iconic costume. In a surprising twist, Gunn, known for his bold creative choices in films like Guardians of the Galaxy and The Suicide Squad, initially envisioned a Superman without his classic red trunks. However, David Corenswet, the actor stepping into the role of Clark Kent, played a pivotal part in convincing Gunn to keep this traditional element, arguing that it carries a deeper significance than mere aesthetics. According to Corenswet, the red trunks make Superman a figure that children instinctively trust—a sentiment that ultimately won over the director.
Gunn’s hesitation to include the red trunks isn’t entirely unexpected. Since Zack Snyder’s Man of Steel in 2013, the trunks—a staple of Superman’s look since his debut in 1938—had been absent from live-action portrayals, replaced by a sleeker, more modern design. Many fans embraced this update, seeing the trunks as a relic of a bygone era, while others mourned the loss of a symbol tied to Superman’s Golden Age roots. Gunn, who’s never shied away from reimagining characters, reportedly leaned toward a minimalist approach when he began crafting his vision for the DC Universe’s reboot. Early costume sketches leaked online in late 2024 showed a streamlined suit with muted colors, drawing inspiration from the New 52 comics, where the trunks were famously ditched.
Enter David Corenswet, a 31-year-old actor whose casting as Superman was announced in June 2023. Known for roles in Netflix’s The Politician and Hollywood, Corenswet brings a fresh face to the character, blending the classic charm of Christopher Reeve with a modern sensibility. During costume discussions, he reportedly pushed back against Gunn’s initial design. “I told James, ‘Look, I get it—modernizing Superman makes sense,’” Corenswet said in a recent interview with Empire Magazine. “But those red trunks? They’re not just underwear. They’re a signal. Kids see them and feel like this guy’s approachable, not some distant god. He’s the hero they can run to.” His argument hinged on Superman’s role as a beacon of hope, particularly for younger generations.
This perspective struck a chord with Gunn, who’s known for his knack for balancing humor, heart, and spectacle. The director, who co-wrote the script with his wife and Peacemaker collaborator Jennifer Holland, admitted that Corenswet’s reasoning shifted his outlook. “David came at it from a place I hadn’t considered,” Gunn shared on Threads in early 2025. “I was so focused on making Superman feel grounded and relevant that I almost forgot how much he means to kids. The trunks bring a lightness, a warmth. They’re staying.” The final costume, revealed in a teaser image at San Diego Comic-Con in July 2024, blends the best of both worlds: a textured, battle-ready suit with a vibrant red cape and, yes, those unmistakable red trunks.
The decision has sparked a lively debate among fans. Some praised the return to tradition, arguing that the trunks are as essential to Superman as the “S” shield. Others questioned whether they clash with Gunn’s otherwise contemporary tone. Yet Corenswet’s logic—rooted in Superman’s identity as a protector—seems to resonate widely. Child psychologists consulted by Variety in a follow-up piece noted that bright, primary colors like red can indeed signal safety and friendliness to young minds, aligning with Superman’s ethos of reassurance over intimidation.
Filming for Superman wrapped in March 2025, and the movie promises a mix of high-stakes action and emotional depth. Set in a world where superheroes are already established, it follows Clark Kent as he navigates his dual life, facing off against a reimagined Lex Luthor (played by Nicholas Hoult) and a mysterious alien threat. Corenswet’s Superman is joined by Rachel Brosnahan as Lois Lane, Nathan Fillion as Green Lantern Guy Gardner, and Milly Alcock as Supergirl, setting the stage for a sprawling DCU. Early test screenings in April 2025 have garnered positive reactions, with audiences highlighting Corenswet’s earnest portrayal and the costume’s nostalgic yet fresh feel.
As the release date nears, this fun fact about the red trunks underscores the collaborative spirit behind the film. Gunn’s willingness to listen to Corenswet shows a director open to evolving his vision, while Corenswet’s insight reveals an actor deeply invested in the character’s legacy. Whether the trunks will become a defining feature of this new Superman era remains to be seen, but one thing’s clear: they’re more than just a fashion statement—they’re a bridge between the hero and the kids who look up to him. What do you think of this costume choice? Let the countdown to July 11, 2025, begin!
