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. Filming begins 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 will play either Jean Grey or another iconic red-headed Spider-Man character, possibly Mary Jane Watson. However, how this would impact Peter Parker's relationship with MJ (Zendaya) remains unclear. Deadline suggests Sink will have a significant role, potentially resetting elements following the events of Spider-Man: No Way Home, where Peter's identity was erased and he reconnected with MJ.
Holland is currently filming Christopher Nolan's The Odyssey, and is expected to begin Spider-Man 4 filming upon its completion.
Late last year, Marvel Studios head Kevin Feige hinted at the introduction of X-Men characters in upcoming MCU films. He stated 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, X-Men appearances are likely throughout Phase 6, including Avengers: Doomsday and Spider-Man 4 (both 2026), and Avengers: Secret Wars (2027). The potential return of Deadpool, Wolverine, and Channing Tatum as Gambit remains a key question. Feige has confirmed the X-Men will be crucial to the MCU's future post-Secret Wars.
Every Confirmed Mutant in the MCU (So Far)
Marvel added three untitled movie projects to its 2028 release schedule (February 18, May 5, and November 10), increasing speculation that at least one will be X-Men-centric. Phase 7 appears poised to be heavily influenced by the X-Men, with Storm's appearance in What If...? Season 3 marking her MCU debut.
