Leaked Spider-Man image confirms Sadie Sink as Jean Grey, fans claim

According to a leaked image and Marvel insiders, Sadie Sink appears to be playing Jean Grey in Spider-Man: Brand New Day. The image, allegedly from the film's set, shows the Stranger Things actress in what fans are calling Jean Grey's signature green costume — finally confirming months of speculation about her mysterious Marvel role.

What the leaked image shows

The image shows Sink wearing a dark green coat with a lighter hood, colours that immediately reminded fans of Jean Grey's classic X-Men uniform. According to noted Marvel insider AlexfromCC, the leaked photo is legitimate and matches costume descriptions he's been sharing for months. The image also aligns with brief glimpses in the Spider-Man: Brand New Day trailer, where someone in similar green attire appears strapped to a chair.

Public filming photos from last year captured Sink wearing the same green coat and yellow hoodie combination, adding weight to the Jean Grey theory. The costume's colour scheme directly references the character's iconic comic book appearances across numerous X-Men storylines.

Why fans are convinced it's Jean Grey

Marvel insiders have increasingly rallied around Sink playing Jean Grey rather than other rumoured characters. It's become clear she's not portraying a typical Spider-Man villain — Brand New Day already features half a dozen antagonists. According to reports, Sink will return in 2027's Avengers: Secret Wars, suggesting a much larger MCU role ahead.

The timing makes strategic sense for Marvel Studios. With Jake Schreier directing the upcoming X-Men reboot, introducing Jean Grey now allows audiences to meet the next generation of mutants before legacy characters potentially exit in Avengers: Doomsday. This approach mirrors Marvel's typical world-building strategy.

Sadie Sink's secrecy struggle

Speaking on The Tonight Show Starring Jimmy Fallon last year, Sink described keeping her Marvel role secret as 'torture.' The actress has maintained complete silence about her character despite mounting speculation and fan theories. Marvel's notorious secrecy protocols mean this torture will likely continue until the studio makes an official announcement — or leaves it as a surprise until the film's release.

The leaked image hasn't received official verification from Marvel Studios or Sony Pictures, maintaining the uncertainty that's defined this casting rumour for months.

When and where to watch in UAE

Spider-Man: Brand New Day arrives in UAE cinemas on 31 July 2026. The film will be available across major cinema chains including VOX, Reel, and Novo. Expect the usual IMAX and premium format screenings, though specific UAE showtimes and booking details won't be announced until closer to release.
