Spider-Man 4 is casting its net toward Hawkins, Indiana, as it welcomes Stranger Things star Sadie Sink into the fold.
According to Deadline, Sink will join Tom Holland, who reprises his role as Peter Parker.
Details about Sink’s character remain under wraps, though her part is anticipated to be “significant.” Some speculations have emerged linking her to the X-Men franchise. In December, Jeff Sneider reported that she’s in the mix to potentially portray Jean Grey within the Marvel Cinematic Universe. Given her red hair, there’s also speculation about her playing a new version of Mary Jane Watson. However, none of these casting rumors have been officially confirmed.
Sink is widely recognized for her role as Max Mayfield on the hit Netflix series Stranger Things, which has recently concluded production on its fifth and final season, set to debut later this year. Additionally, she will appear in O’Dessa, a Hulu post-apocalyptic musical premiering on March 20.
The X-Men are set to join the MCU soon, as Marvel Studios president Kevin Feige has announced that the “Mutant Era” is now underway, following the success of Deadpool & Wolverine. With Grey being a crucial character in the X-Men lore, her introduction alongside Spider-Man could be a strategic move.

As for the rest of the cast, Zendaya is expected to return as Michelle “MJ” Jones-Watson, although she has yet to finalize her contract. It remains uncertain if other actors from the previous Holland-led trilogy, including Jacob Batalon as Ned, will reprise their roles in Spider-Man 4.
Holland’s fourth installment as Spider-Man serves as a sequel to the 2021 film Spider-Man: No Way Home. In the finale of No Way Home, Peter Parker uses Doctor Strange’s (Benedict Cumberbatch) spell to make the world forget him for the greater good of the universe. Although everyone forgets Peter Parker, Spider-Man’s legacy continues, evident in the concluding scene featuring his new suit.
Destin Daniel Cretton is set to direct Spider-Man 4, with Sony’s Amy Pascal and Feige onboard as producers. Production is anticipated to begin once Holland completes filming for Christopher Nolan’s upcoming film, The Odyssey.
Spider-Man 4 is scheduled to hit theaters on July 31, 2026.
