Who isn’t familiar with the Stranger Things cast! Sadie Sink (who played Max) is the new addition to a new verse, which is Spider-Man.
Sadie Sink is joining the Marvel Cinematic Universe (MCU) for Spider-Man 4 and she will be joining the screen with Tom Holland. Although Sadie Sink in Spider-Man 4 is confirmed, her role stays hush-hush for now.
What role will Sadie Sink play in Spider-Man 4?
As per Deadline, Marvel Studios and Sony Pictures have made no comment about the news yet. However, it is theorized that her role will be “significant”.
Also, the theory suggests that Sadie Sink X-Men character Jean Grey might be introduced, but there also remains a strong hunch that she could be seen as Spider-Man’s beloved, Mary Jane.
The internet is full of presumptions in just one day! We bet Marvel and Sony would be enjoying the hype they just created, like igniting fire. There is no poster or teaser that could’ve solved the mystery of Sadie Sink’s Spider-Man 4 role.
Forbes suggested that it is impossible for Sadie to play Zendaya as the past three Spider-Man’s films have dedicated this role to Zendaya. It would be a mess, but since in 2015, when Spider-Man: Homecoming was in the development phase, which is now an exact decade ago, Marvel Universe thought of transforming Mary Jane into Michelle Jones Watson, which has the same initials, MJ.
Rotten Tomatoes film reviewer and Forbes’ senior contributor said,
“This remains a mess. Even after all three movies, there has still not been confirmation one way or the other that Zendaya is supposed to be the “official” Mary Jane in the MCU.”
After Doctor Strange’s spell that erased Spider-Man’s existence and memory from his girlfriend’s and friend’s brain cells, there is a chance that a metamorphosis could be witnessed with a changed Mary Jane in the form of Sadie Sink.
It is likely that Spider-Man has forgotten MJ, and with a new storyline in 2026, MJ has transformed as well, emerging as Sadie Sink? Just in the mood to play ring toss with random guesses?
How did fans react to Sadie Sink in Spider-Man 4?

It is obvious to think that with her red hair, Sadie Sink might be playing Mary Jane in Spider-Man 4. However, fans have strong opinions. Some of them speculate that Tom Holland can’t let his girlfriend be replaced that easily.
After all, Zendaya has been playing the said role in the past three Spider-Man films. Marvel has also been quiet on the news about whether Sadie Sink is coming as a replacement for the role; still, no clarification.
An interesting Reddit thread revealed responses from users in which most of them nullified the possibility of Sadie Sink being Mary Jane or MJ. Also, it should be noted that fans are strongly opinionated by the fact that her name was established as Michelle Jones Watson in Spider-Man: No Way Home and that we should stop calling her Mary Jane now.
Besides, fans are adamant that Marvel already has a Mary Jane in the form of Zendaya. Otherwise, a breaking news story would have appeared referring to Sadie Sink coming as Zendaya’s replacement.
After digging deep into these responses, it became clearer that Gwen, Firestar, Jean Grey, and Screwball are the top-most cogitated characters that Sadie Sink could play in the movie.
Spider-Man 4 fan theories surround Gwen Stacy’s existence if Sadie Sink is added to the cast for this purpose. Gwen Stacy could be Peter Parker’s next love interest if Zendaya’s MJ has no memory of Peter, as shown in the last part.
Another theory emphasizes Sadie as Black Cat, a New York vigilante, and a potential budding romantic interest for Peter Parker in fourth part.
On the other hand, blowing up all the theories related to Sadie being portrayed as Spider-Man’s love interest only, there is a strong prospect that Sadie will be seen as Firestar- Spider-Man’s close friend, created from scratch in the list of his ‘Amazing Friends’ beside another fellow mutant, Iceman.
Possible roles for Sadie Sink in Spider-Man 4
- Jean Grey (mutant from the X-men universe)
- Mary Jane Watson (Spider-Man’s love interest)
- Gwen Stacy (another possible love interest for Peter Parker)
- Firestar (Spider-Man’s ally)
- Black Cat (Vigilante)
- Screwball (an internet supervillain but minor chances)
Did Tom Holland say anything about Sadie Sink yet?
Tom Holland is busy shooting for Christopher Nolan’s The Odyssey, and he plans to start shooting for Spider-Man 4 afterward.
For now, no comments were recorded from Tom Holland, probably due to his busy schedule.
Has any other crew member spilled the beans on Sadie Sink’s role?
Spider-Man 4’s director, Destin Daniel Cretton, writers Chris McKenna and Erik Sommers, and producers Kevin Feige, Amy Pascal, and Avi Arad have not unmasked any details for Sadie Sink’s role in Spider-Man 4.
The movie remains untitled, and the plot and Sadie’s character remain under the covers as well.
How does Sadie Sink’s casting affect the Spider-Man storyline?
Tom Holland will reprise his role as Spider-Man in its fourth instalment. The movie is going to be on screen in 2026 between two other releases from Marvel Studios- Avengers: Doomsday and Avengers: Secret Wars.
Sadie Sink’s casting could potentially prove a bridge between the existing Marvel properties. She could bring the vibrancy that is needed for a significant expansion of the universe’s characters.
While the plot details of Spider-Man 4 remain unknown, Spider-Man 3 showed the titular character opening a portal with two other Spider-Men coming into view.
Now with Sadie Sink added to the cast, excitement and curiosity are on the rise regarding her identity and contribution to the storyline, especially the apt timing of Spider-Man 4’s release in between the other two Marvel’s features.
Spider-Man 4 is expected to be released in 2026. Till then, we are left to make guesses until we get some official news.
