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 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 beginning later this year.

Marvel and Sony have yet to comment on the casting news. Deadline speculates Sink's role could be either Jean Grey or another popular redheaded Spider-Man character, possibly hinting at Mary Jane Watson. However, this raises questions about how her introduction would impact Peter Parker's current relationship with MJ (Zendaya). Deadline suggests Sink will have a significant role, potentially acting as a reset following the events of *Spider-Man: No Way Home*, where Peter's identity was erased and he reconnected with MJ.

Tom Holland is currently filming *The Odyssey* for Christopher Nolan, and is expected to begin filming *Spider-Man 4* upon its completion.

Late last year, Marvel Studios head Kevin Feige hinted at the introduction of X-Men characters in upcoming MCU films. He teased that fans would see familiar X-Men characters in the "next few" MCU movies, without specifying which characters or films. Feige further emphasized the X-Men's importance in the MCU's future, particularly after *Secret Wars*.

Considering Feige's comments, the next few films—*Captain America: Brave New World*, *Thunderbolts*, and *The Fantastic Four: First Steps*—are potential candidates for X-Men appearances. However, it's more likely that mutant appearances will be spread throughout Phase 6, including *Avengers: Doomsday*, *Spider-Man 4*, and *Avengers: Secret Wars*. The return of Deadpool, Wolverine, and potentially Channing Tatum as Gambit remains a key question.

Feige highlighted the X-Men's crucial role in the MCU's future after *Secret Wars*, stating that their inclusion is a significant part of the long-term narrative plan. Phase 7 is expected to feature prominently the X-Men, although Storm's appearance in *What If...?* Season 3 marked an early introduction.

Every Confirmed Mutant in the MCU (So Far)

With Marvel adding three untitled movie projects to their 2028 release schedule, the possibility of an X-Men film is increasingly likely.
