Marvel fans are pushing back after a viral social media post claimed that many believe actress Sadie Sink will play a version of Wanda Maximoff, better known as the Scarlet Witch, in the upcoming film Spider-Man: Brand New Day. The speculation resurfaced after a popular entertainment page shared a video discussing Sink's reportedly secretive casting process. According to the post, Marvel skipped a traditional audition for Sink and allegedly kept the script from her until filming began to protect the project's secrets. The caption also claimed that fans believe she will portray a version of Scarlet Witch.
That last claim quickly became the real story. Rather than embracing the Wanda theory, hundreds of commenters argued that almost no one has been speculating that Sink will play the Scarlet Witch. One top comment read, The fans are not convinced she'll be playing Scarlet Witch. Another user wrote, Literally nobody thinks this. Many questioned where the theory even originated, with users asking, Who's 'the fans'? and joking that the caption felt like clickbait. The pushback was immediate and widespread, revealing a clear disconnect between the viral narrative and the actual fan community discussing the film.
The Jean Grey Theory Takes Center Stage
Instead of Scarlet Witch, the overwhelming majority of commenters pointed to one X-Men character: Jean Grey. So clear it's Jean Grey, one fan wrote. Everyone has been guessing Jean Grey, another commented. Others claimed that longtime Marvel insiders have fueled that theory for months, while several users argued that introducing Jean Grey would make sense if Marvel Studios is preparing to bring the X-Men into the Marvel Cinematic Universe.
Jean Grey is one of Marvel's most powerful and beloved mutants, known for her telepathic and telekinetic abilities as well as her connection to the Phoenix Force. Her story arcs, including the iconic Dark Phoenix saga, have been a staple of X-Men comics for decades. If Sadie Sink were cast as Jean Grey, it would mark a significant step toward integrating the X-Men into the MCU, potentially setting up future crossovers or even a new team film. Fans noted that the timing aligns with Marvel's recent hints at mutant characters appearing in upcoming projects, such as the confirmed X-Men film in development.
However, not everyone agreed with that prediction. Some questioned why Marvel would introduce such a major mutant character in a Spider-Man film rather than in a dedicated X-Men project. Others pointed out that the MCU's version of Jean Grey could be a younger iteration, allowing for a fresh start separate from the Fox films. The debate highlighted the complexity of bringing legacy characters into an established cinematic universe.
Other Fan Theories and Possibilities
While Jean Grey dominated the discussion, commenters floated several other possibilities for Sink's role. Some predicted she could play Rachel Summers, Jean Grey's daughter from an alternate timeline, a character with strong ties to Phoenix lore. Others suggested Spider-Gwen, Cindy Moon (also known as Silk), Mary Jane Watson, Typhoid Mary, or even Madame Web. This variety of theories is a direct example of how tightly Marvel has kept Sink's role under wraps, leaving fans to speculate wildly.
The inclusion of Spider-Gwen would be particularly notable, as the character has gained a massive following through the Spider-Verse animated films and comics. However, that role would likely require a distinct visual and character departure from Sink's previous work. Cindy Moon as Silk is another popular choice, as she is a spider-themed hero with a rich history in the comics, though her introduction might be overshadowed by Spider-Man's narrative. Typhoid Mary is a more obscure option, known as a Daredevil villain with multiple personality disorder, but her connection to the wider Marvel underworld could fit a street-level Spider-Man story. Madame Web, an elderly clairvoyant, seems less likely for a young actress like Sink, but the multiverse angle in Spider-Man: Brand New Day could allow for any interpretation.
Concerns Over Replacing Elizabeth Olsen
Some Marvel fans also voiced concern over the Scarlet Witch speculation, arguing that Elizabeth Olsen remains the definitive face of the character. If she replaces Elizabeth Olsen I will be so mad, one commenter wrote. Another added, There's no replacing an Olsen. Others pointed out that Wanda Maximoff already exists within the MCU, played masterfully by Olsen across multiple films and the WandaVision series, making the theory feel unlikely in their eyes. Introduced in Captain America: The Winter Soldier and solidified as a key Avenger, Olsen's portrayal has earned critical acclaim and a dedicated fanbase. Recasting the role in a Spider-Man film, especially without clear narrative justification, would risk alienating audiences. The outcry suggests that fans are protective of established character arcs and see little reason to introduce a new version of Scarlet Witch, especially when the character's storylines are far from resolved.
Moreover, the MCU's current trajectory includes a multiverse saga, which could theoretically allow for variant versions of characters. However, fans argue that using that device to replace a beloved actress would cheapen the emotional investments built over years. The sentiment is that Marvel should focus on original casting for new characters rather than recasting existing ones in confusing ways.
The Secrecy Behind Sadie Sink's Casting
Marvel Studios has not confirmed which character Sink will portray in Spider-Man: Brand New Day, and the actress has remained equally tight-lipped. That secrecy has only fueled months of online speculation, with fans continuing to dissect every rumor leading up to the film's release. The reportedly secretive casting process described in the viral post—where Sink was kept in the dark about the script until filming—is consistent with Marvel's typical approach to preventing leaks. The studio has a history of using code names, fake scripts, and closed sets to protect surprises, especially for major crossover events.
Sink herself is no stranger to high-profile roles. She rose to fame as Max Mayfield in Netflix's Stranger Things, earning widespread praise for her emotional depth and intensity. Her transition to the superhero genre has been anticipated by fans, and her signing with Marvel suggests the studio sees her as a major addition to the franchise. Whether she plays a hero, villain, or something in between, her casting signals that the role will be significant. As of now, Spider-Man: Brand New Day is expected to continue the story of Tom Holland's Peter Parker after the events of Spider-Man: No Way Home, which ended with the multiverse in chaos and everyone forgetting Peter's identity. The film will likely explore the consequences of that spell while introducing new allies and threats.
For now, though, one thing appears clear from the viral post's comment section: while plenty of fans have theories about Sink's mysterious role, most do not believe Scarlet Witch is the answer. Instead, the fanbase continues to champion Jean Grey as the most likely character, leaving Marvel to reveal whether they are right when the film hits theaters. Until then, the speculation will only intensify as more details emerge about the production and the broader direction of the MCU's next phase.
