Sadie Sink Joins Tom Holland in Spider-Man 4

Sadie Sink, known for her role as Max Mayfield in Stranger Things, is reportedly joining Tom Holland in Spider-Man 4. Deadline reports that Sink, whose film debut was in the 2016 film Chuck, will appear in the upcoming MCU movie, slated for release on July 31, 2026, with filming commencing later this year.

Marvel and Sony have declined to comment on the casting. Deadline speculates Sink's role could be either Jean Grey or another iconic redheaded Spider-Man character, possibly hinting at Mary Jane Watson. However, how this introduction would interact with Peter Parker's existing relationship with MJ (Zendaya) remains unclear. Deadline suggests Sink will have a significant role, potentially contributing to a reset following the events of Spider-Man: No Way Home, which saw Peter reconnecting with MJ after Doctor Strange altered memories.

Holland is currently filming Christopher Nolan's The Odyssey, and is expected to begin filming Spider-Man 4 upon completion.

Late last year, Marvel Studios head Kevin Feige hinted at the introduction of X-Men characters in upcoming MCU films, stating that fans would see "some X-Men players that you might recognize" in the next few movies. He further emphasized the X-Men's importance in the MCU's future, particularly following Secret Wars.

Every Confirmed Mutant in the MCU (So Far)

Considering Feige's comments, Phase 6 films, including Avengers: Doomsday, Spider-Man 4 (2026), and Avengers: Secret Wars (2027), are likely candidates for further mutant appearances. The potential return of Deadpool, Wolverine, and even Channing Tatum as Gambit remains a significant question. Feige has confirmed the X-Men will be a crucial part of the MCU's future after Secret Wars.

Phase 7 appears poised to be heavily X-Men-focused. Storm's appearance in What If...? Season 3 marked her MCU debut. Marvel Studios has also added three untitled movie projects to its 2028 release schedule, increasing speculation about an X-Men film.
