The Marvel rumor mill is in full meltdown mode—and this time, it’s all about Sadie Sink. As far as rumors go, Cryptic HD QUALITY’s (@Cryptic4KQual) scoop that Sadie Sink would play Jean Grey in the upcoming movie “Spider-Man: Brand New Day” hasn’t exactly been taken well by fans. The problem? Marvel Studios hasn’t said anything official—and yet, timelines are spinning wildly out of control.
Jean Grey casting rumors explode after reports
To many Marvel Studios watchers, this rumor isn’t exactly a wild guess. To many, this rumor feels like it’s been quietly building for months.
For those unfamiliar, Sink rose to international fame playing roles in the hit Netflix show “Stranger Things.” Fans have been casting her as Jean Grey for quite some time. So when rumors came out indicating that her character would wear Jean Grey’s classic color scheme—a bright yellow and green—fans immediately caught wind. That’s not exactly a vague rumor—that’s a very specific rumor. And in the world of Marvel rumors, “specific” means suspiciously believable.
Of course, the rumor mill didn’t start to go completely bonkers until power level rumors came out.
According to widely spread rumors, Sink’s character does not exactly debut in a subtle manner. In fact, she blows into the Marvel Cinematic Universe like a force of nature. One rumor even went so far as to indicate that she would display her powers in a battle against Hulk—powers like telepathy and mind control. The rumor that sent the rumor mill into absolute meltdown mode? The rumor is that she forces Bruce Banner out of his “Smart Hulk” persona and into his “Savage Hulk” persona. Suddenly, this mill isn’t speculating whether or not she’s playing Jean Grey—it’s speculating whether or not they’re getting a top-tier Omega-level mutant right out of the gate.
There are also whispers that the Department of Damage Control is actively hunting her, which fans believe is Marvel’s subtle hint at introducing its much-awaited mutant storyline. As soon as Marvel acquired the rights to X-Men, fans have been waiting for this moment to integrate mutants into the Marvel Cinematic Universe. This rumor, however, might mean that this is not a cameo appearance but rather a proper introduction to Jean Grey’s storyline, should this rumor prove to be true.
Of course, there is also a certain level of unpredictability to this rumor, considering that Marvel also introduces Frank Castle, played by Jon Bernthal, who is a part of this rumor, as Sink’s mutant joins forces with the Punisher, a morally ambiguous anti-hero, to take down a threat to their mission.
There are also rumors that Sink’s Jean Grey might actually mind-control Liza Colón-Zayas’s character during a tank-filled action scene, which, should this rumor prove to be true, might mean that this Jean Grey is a bit more unpredictable and perhaps more on the villainous side than fans might think.
This rumor, however, is not a one-film rumor, as Marvel insiders also speculate that Sink might be a part of Avengers: Secret Wars and Marvel’s X-Men reboot. This, for fans, is perhaps the strongest hint yet, considering that Marvel would never introduce Jean Grey halfway but rather build a story around this iconic Marvel character.
Of course, this is all rumor for now, but considering Marvel’s tendency to remain tight-lipped about their productions, this rumor seems to be a bit too detailed to be dismissed as mere rumor.
