Tom Holland’sSpider-Man 4has finally begun its casting process. TheMarvel Cinematic Universemovie will go into production later this year, with Holland’s Peter Parker the only confirmed character to be back forSpider-Man 4’s mystery story. Zendaya’s MJ is reportedly set to have a minor role in theupcoming MCU film, though Marvel has yet to comment on that claim. After months of little updates on the status of the next Spider-Man film, Holland’s fourth MCU solo entry as Spider-Man has now received a major piece of casting news.
According toDeadline,Stranger Thingsstar Sadie Sink has joinedSpider-Man 4in an undisclosed role. The report suggests the leading theory about who she could be playing is a member of the X-Men, Jean Grey. However, it also claims that “another beloved redheaded Spider-Man character” should not be discarded. That nod is clearly related to Mary Jane Watson, Peter Parker’s most famous love interest in Marvel Comics. Since Zendaya’s MJ took over the character’s role and nickname in theMCU’s Spider-Man movies, Sink’sSpider-Man 4role could end up being a shocking move from Marvel and Sony.

What Sadie Sink’s Spider-Man 4 Casting Means
The Actress Could Completely Change The MCU
The timing of Sink’s casting is certainly intriguing. In December 2024,Sink was reported as the frontrunner for the MCU’s Jean Grey. At the time, there was no project mentioned as to where the X-Men character could make her debut in the franchise, but the latestSpider-Man 4news makes the situation interesting. The new Spider-Man movie report mentioned thatthe main theory is that Sink is playing Jean Grey, as was previously reported. At 22, theStranger Thingsactress could stay in the MCU for more than a decade, which fits Marvel’s likely approach for the X-Men.

The Multiverse Saga and beyond can introduce a few key Marvel heroes, from the X-Men to more, who could completely change the MCU in exciting ways.
When it comes to Mary Jane Watson, another character teased by the report, things start to become more complicated. Zendaya’s MJ, while completely different from Mary Jane personality-wise, filled the character’s role in the MCU. She is even called “MJ,” the MCU’s nod to Peter Parker’s biggest love interest in the comics. That said, Sink’s performance as Max Mayfield inStranger Thingsshows she has the kind of confident attitude Mary Jane is known for.Black Cat had also been previously rumored forSpider-Man 4, and Sink has played characters comfortable with danger before to make Felicia Hardy exciting.

Our Take On Sadie Sink’s Spider-Man 4 Casting
The Multiverse Rumors Might Be True After All
Based on how Sink was previously reported to be in line to play the MCU’s Jean Grey and how she is perfect for that whole in terms of looking exactly like her and having the skills to make Jean pop, I believe that herSpider-Man 4role will end up being the X-Men member. That creates many questions related towhy Jean would be in the film. Since Tom Holland’s next Spider-Man movie is set betweenAvengers: DoomsdayandSecret Wars, it is possible that some X-Men members will appear in all three films, makingSpider-Man 4a multiverse story.
