Spider-Man:

Brand New Day is already sparking major fan buzz, and confusion, thanks to a mysterious new on-set sighting. After months of speculation, the first look at Stranger Things star Sadie Sink alongside Spider-Man actor Tom Holland has surfaced online, leaving fans debating who she’s actually playing, Jean Grey, Mary Jane Watson, or someone else entirely.

Sadie Sink on Spider-Man sets

The upcoming Spider-Man: Brand New Day marks Tom Holland’s long-awaited return to the Marvel Cinematic Universe, following his absence since No Way Home (2021). Set for a 2026 release, the film is being helmed by Shang-Chi director Destin Daniel Cretton and is currently in production. A new behind-the-scenes photo shared online shows Sadie Sink chatting with Cretton while wrapped in a beige hoodie. Holland was also spotted nearby, filming in full Spider-Man costume while suspended on wires, marking his first major shoot since recovering from a mild concussion last month.Sink, who joined the cast earlier this year, was photographed in camo combat pants and military-style boots, with her trademark red hair left natural. This simple look has only intensified the guessing game about her character. Some fans insist she’s playing Mary Jane Watson, Peter Parker’s longtime love interest, while others believe she could be Mayday Parker - Spider-Man’s daughter from the comics. A few even speculate that she might be Jean Grey, though that theory has raised eyebrows among MCU fans, given Jean’s usual connection to the X-Men rather than Spider-Man’s world.

Fans confused about Sadie's role

The online debate has been intense, with comments like, “MJ, Mayday, Jean? Who lol” and “Those who are saying Jean Grey need to realize Sadie is too short to play Jean lol.” Another fan pointed out, “Is no one noticing the potential camo pants and military boots?” hinting she could even be a new character, possibly Frank Castle’s mysterious female partner. Another was confident and stated, "Idk man it’s pretty obvious she’s playing Mary Jane or Jean grey lol".Whether she’s swinging through New York or stepping into Marvel’s mutant universe, Sadie Sink’s Spider-Man: Brand New Day debut has fans hooked before the trailer’s even out.
