The Marvel Cinematic Universe (MCU) continues to captivate audiences with its ever-expanding roster of heroes, and the latest buzz surrounding Spider-Man: Brand New Day has fans on the edge of their seats.

Sadie Sink, best known for her role as Max Mayfield in Stranger Things, has ignited a firestorm of excitement with her confirmed role as Spidergirl in the upcoming MCU film, set to hit theaters on July 31, 2026. Recent set photos from Glasgow, Scotland, where filming is underway, have revealed Sink’s striking new look, further fueling speculation and enthusiasm about her character’s place in the Spider-Man saga. Alongside this, Sink has shared tantalizing hints about her role, keeping the internet abuzz with theories and anticipation.

The announcement of Sink’s casting in Spider-Man: Brand New Day first broke in March 2025, when Deadline reported her involvement in an undisclosed role. Since then, fans and insiders alike have speculated wildly about who she might portray, with names like Gwen Stacy,

 Jean Grey, Mayday Parker, and even Firestar floating around online forums and podcasts. However, a recent rumor, backed by industry insider Kristian Harloff and reported by outlets like SuperHeroHype, suggests Sink will take on the mantle of Spidergirl, a character tied to the rich lore of Marvel Comics. This revelation has sent shockwaves through the fandom, as Spidergirl—often associated with May “Mayday” Parker, the daughter of Peter Parker and Mary Jane Watson in alternate universes—represents a bold new direction for the MCU’s Spider-Man franchise.

Set photos circulating on platforms like X have offered the first glimpse of Sink in costume, showcasing a sleek, modern take on the Spidergirl suit. The design blends classic Spider-Man aesthetics with a fresh, youthful edge, featuring a vibrant red-and-blue color scheme with subtle nods to the comic book source material.

Fans have taken to social media to praise the look, with many noting how Sink’s fiery red hair and dynamic presence make her a perfect fit for the role. The images, reportedly captured during public filming in London, have only heightened anticipation for how her character will interact with Tom Holland’s Peter Parker, especially given the film’s rumored multiversal elements.

Directed by Destin Daniel Cretton, known for Shang-Chi and the Legend of the Ten Rings, Spider-Man: Brand New Day promises to be a pivotal chapter in the MCU’s Phase Six. The film sees Holland reprising his role as Peter Parker, alongside returning cast members Zendaya as MJ and Jacob Batalon as Ned Leeds. New additions, including Jon Bernthal as The Punisher, Mark Ruffalo as Bruce Banner/Hulk, and Michael Mando as Scorpion, hint at a narrative packed with both street-level conflicts and broader MCU connections. The title, inspired by the 2008 comic storyline, suggests a “fresh start” for Peter Parker, potentially exploring themes of identity and legacy in the wake of Spider-Man: No Way Home.

Sink herself has remained coy about her role, but in a recent interview with Deadline, she addressed the swirling rumors with enthusiasm. “They’re awesome rumors,” she said, neither confirming nor denying specifics but expressing excitement about joining the MCU. Her comments have only deepened the mystery, with some fans speculating that her Spidergirl could hail from an alternate universe, possibly tied to Tobey Maguire’s Peter Parker, as suggested b
