Spider-Man 4 Casts Stranger Things’ Sadie Sink to Star Alongside Tom Holland, Reportedly as Either X-Men Favorite Jean Grey or Mary Jane Watson

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 Marvel Cinematic Universe (MCU) movie. Filming is slated to begin later this year, with a release date set for July 31, 2026.

Marvel and Sony have declined to comment on the casting news. Deadline speculates Sink's role could be either Jean Grey or another iconic redheaded Spider-Man character, possibly Mary Jane Watson. However, the introduction of another Mary Jane-type character alongside Zendaya's MJ presents an intriguing narrative challenge. Deadline suggests Sink will have a "significant" role, potentially contributing to a kind of reset following the events of Spider-Man: No Way Home, where Peter Parker's identity was erased and his relationship with MJ was re-established.

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

Late last year, Marvel Studios head Kevin Feige hinted at the introduction of X-Men characters in upcoming MCU films. He teased the appearance of recognizable X-Men characters in the "next few" MCU movies, without specifying which characters or films. Feige further emphasized the X-Men's significant role in the MCU's future, particularly in the lead-up to and aftermath of Secret Wars.

Considering Marvel's release schedule, the "next few" films might include Captain America: Brave New World, Thunderbolts, and The Fantastic Four. However, X-Men appearances are more likely spread across Phase 6, encompassing Avengers: Doomsday, Spider-Man 4, and Avengers: Secret Wars. The potential return of Deadpool, Wolverine, and even Channing Tatum as Gambit remains an open question.

Feige has confirmed the X-Men's crucial role in the MCU's future following Secret Wars, highlighting a long-term plan extending beyond the immediate future.

Phase 7 is anticipated to be heavily X-Men focused. While Storm's appearance in What If...? Season 3 marked a first step, Marvel Studios has added three untitled movie projects to its 2028 release schedule, fueling speculation about a dedicated X-Men film.
