Sadie Sink Joins Cast of 'Spider-Man 4' in Significant Role

The Stranger Things star's role in the Tom Holland-led Marvel sequel remains unconfirmed, fueling speculation about her character.

Sadie Sink, best known for her role in Stranger Things, has been cast in the upcoming Spider-Man 4, set for release on July 31, 2026.
While her role is not officially confirmed, speculation suggests she may portray X-Men's Jean Grey, a multiversal version of Mary Jane Watson, or another Marvel character.
Zendaya is expected to return as MJ in a reduced capacity due to her busy schedule, including other major projects like Dune 3 and Euphoria Season 3.
Spider-Man 4 will continue the storyline from No Way Home, focusing on Peter Parker's life after erasing his identity from the world.
The film will be directed by Destin Daniel Cretton, with production slated to begin later this year after Tom Holland completes filming The Odyssey.
