Spider-Man 4’s recent casting announcement is not only very exciting, but it could allow Tom Holland’s big MCU dream to finally become a reality. The story of Spider-Man 4 is still mostly under wraps, but that has not stopped a big reveal from being made ahead of the film’s mid-2025 shooting date. This announcement came in the form of Sadie Sink’s Spider-Man 4 casting, with the Stranger Things star set to play opposite Tom Holland in the next installment of the Web-Slinger’s journey.
Naturally, this reveal sparked a great deal of speculation and theorization, primarily centered around which Marvel character Sadie Sink could be playing in Spider-Man 4. From theories that Mary Jane Watson would receive a more faithful adaptation with Sink in the role to other love interests like Gwen Stacy or popular mutants like Jean Gray and Firestar, Sadie Sink’s casting is undeniably the biggest talking point of the film thus far. However, a different theory entirely has cast Sadie Sink as another Marvel character, one who could fulfill a dream Tom Holland has long held for his MCU Spider-Man timeline.
