Sadie Sink Joins ‘Spider-Man 4’: Who Will She Play?

Exciting news for “Stranger Things” fans and Marvel lovers alike; Sadie Sink is set to join the cast of “Spider-Man 4.” The actress, who stole hearts as Max Mayfield in “Stranger Things,” will appear alongside Tom Holland, and there’s a ton of speculation about which iconic character she might play.

Sadie Sink’s Growing Star Power

Sadie Sink has come a long way since her breakout role in “Stranger Things.” Her performance as Max, navigating trauma, strength, and vulnerability, earned her plenty of praise. Beyond Netflix, she’s been flexing her acting chops in movies like “A Sacrifice” and “The Whale” showing her range and dedication. Now, joining the MCU is a big leap, marking a new chapter in her already impressive career.

Fans are eager to see how she fits into the expansive MCU. One viewer commented on a Reddit post about the news saying, “She has the most promising future out of all the main Stranger Things kids, Very Excited,” while another pointed out that, “shes really grown and improved herself to the point where she is the stand out of the cast of kids. Unless it’s an absolutely godawful movie this will be good exposure for her.”

With her ability to balance intensity and charm, it’s clear why Marvel is keen on casting her for such an important role. Whether she’s playing a hero or a villain, Sink’s star power is only going to get brighter. No matter which character she embodies, there’s no doubt that she’ll bring a fresh, exciting energy to the big screen.

Which Iconic Character Will Sink Play?

Naturally, the question on everyone’s mind is: Who exactly is Sadie Sink playing? Two big contenders have emerged in the rumor mill.

One possibility is that Sink could be taking on the role of Jean Grey, one of the most powerful mutants in the “X-Men” universe. Marvel’s plan to integrate the “X-Men” into the MCU seems to be unfolding, and Sink’s red hair makes her a natural fit for the character. Jean’s telepathic and telekinetic powers could bring a new dynamic to the “Spider-Man” universe, especially with the multiverse now being a bigger factor in Marvel’s storytelling. Her power and intensity could make for some incredible on-screen moments.

Another fan theory is that Sink could step into the role of Mary Jane Watson, Peter Parker’s love interest, which Deadline hinted at saying, “don’t count out the idea that she shows up as another beloved redheaded Spider-Man character.” While Zendaya’s MJ has already carved out a unique place in the MCU, the multiverse could easily allow for a different version of Mary Jane to appear. Sink’s mix of toughness and sweetness could bring an interesting twist to the character’s dynamic with Peter.

What Does This Mean for ‘Spider-Man 4’?

“Spider-Man 4,” directed by Destin Daniel Cretton, is set to hit theaters on July 31, 2026. The movie will pick up after the events of “No Way Home,” where Peter Parker erased his identity from everyone’s memory. With Tom Holland still in the lead and Sink joining the cast, it’s clear that this new installment is going to push the boundaries of what we’ve seen from Spider-Man so far.

Fans are already buzzing about how Sink’s character could shake up Peter’s world, and whatever direction the film takes, it’s bound to be a thrilling ride. Whether she’s Jean Grey, Mary Jane, or someone else entirely, Sink’s presence is sure to elevate the movie’s stakes. And the anticipation for “Spider-Man 4” just hit a whole new level.
