Lots of rumors are circulating about Sadie Sink’s role in the upcoming Spider-Man: Brand New Day, and fans are really hyped. However, Marvel hasn’t confirmed anything – all of this is based on unverified claims from people who say they’ve seen early script drafts or footage. Still, it’s always fun for fans to speculate and make predictions before a new Marvel movie comes out, and sometimes those theories are even more exciting than the actual plot!
The latest buzz suggests Sadie Sink might be cast as Jean Grey in an upcoming Marvel project. There’s also speculation about potential connections between her character and established heroes like the Punisher, Hulk, and Spider-Man, specifically within the ‘Spider-Man: Brand New Day’ storyline. A social media post combining a comic book image of Jean Grey with a Sadie Sink interview clip, captioned simply as “She’s Jean Grey,” quickly fueled these rumors.
Fans Want Sadie Sink to Bring Jean Grey Into the MCU
This post didn’t claim Marvel had officially cast Sadie Sink as Jean Grey in Spider-Man: Brand New Day. It simply suggested she looks like the character. The original poster may have been trying to start a discussion, and at least one person took the comment as fact, enthusiastically agreeing that Sink would be perfect for the role and urging Marvel to cast her.
This is such a perfect casting. Don’t mess this up marvel.

One commenter pointed out that Sadie Sink has already demonstrated the range to play both the gentle and intense aspects of the character Jean. Her previous work in films like The Whale and the hit series Stranger Things proves she’s a remarkably skilled actress, especially considering her age.
I can def see her nailing both the soft and aggressive sides of Jean

Some viewers thought the actress was too young for the part, with one even suggesting Julia Roberts. However, Roberts is 58, which would mean Jean Grey’s story would begin and end quickly. The chosen actress, at 23, has the time to develop into the role, and it’s crucial to cast a younger Jean, especially since she’s new to the Marvel Cinematic Universe. An older Jean Grey wouldn’t make sense, as the character hasn’t been established yet.
One person suggested a possible backstory: in the Ultimate Marvel Universe, her powers emerge during an incident, but before Xavier’s School for Gifted Youngsters exists, forcing her to flee. They proposed she could cross paths with the Punisher while on the run, as he often helps those who need it.
There are a lot of unknowns, but it seems likely they’ll base Jean Grey’s story on her original 616 comic book origins. Perhaps the event that gives her powers still happens, but instead of going to Xavier’s school, she goes on the run from her past, pursued by the Department of Defense, and creates a new identity—possibly Carlie Cooper—while forming an alliance with Frank.

Someone else mentioned they’ve been following the rumors and are curious about Sadie Sink’s role in the upcoming Marvel movie. Since no trailers for Spider-Man: Brand New Day have been released yet, it’s unclear whether her character will be teased beforehand or if the reveal will be a surprise when the film comes out.
Now that the news is public, I’m curious if Marvel will hold off on fully revealing the character until the movie comes out, or if they’ll hint at her being Jean Grey in the trailer.

Look, the rumors are flying about Sadie Sink potentially taking on the role of Jean Grey in the upcoming Spider-Man: Brand New Day film, but as of right now, nothing’s confirmed. What’s interesting, though, is that if she does play Jean Grey, it won’t be the same character we’ve seen in the X-Men films from Fox. Instead, it could be a fascinating twist seeing James Marsden’s Cyclops recognize something familiar in her – maybe even realizing she’s a version of the Jean Grey he lost in his own universe. Sink is set to return for Avengers: Secret Wars, so whatever role she plays, it’s clearly going to be significant. Whether she’s Jean Grey or someone else entirely, keep your eyes on her – she’s going to be important.
