Sadie Sink Opens Up About Rumors Surrounding Her Role in Spider-Man: Brand New Day and Avengers: Secret Wars
After wrapping her successful run on Stranger Things, Sadie Sink is stepping into the Marvel Cinematic Universe (MCU), with her much-anticipated role in Spider-Man: Brand New Day fueling plenty of fan speculation. While the actress remains tight-lipped about her character, she recently addressed some of the rumors circulating around her involvement in the superhero film.
Sink’s casting in Spider-Man: Brand New Day has sparked intense online discussions, particularly about the possibility of her playing a well-known comic book character. The biggest speculation? That she could be portraying X-Men’s Jean Grey, a theory that’s gained traction due to her signature red hair.
However, Sink took a lighthearted approach to these theories during an interview with Entertainment Weekly, saying, “A lot of people forget that hair color can change, but yeah, I understand all of the theories.” She’s referring to the fact that, while fans are quick to latch onto certain details—like her hair color—casting choices in the MCU often surprise with unexpected twists and transformations.
Despite the growing buzz, Sink has remained firmly silent on specifics about her role, adding, “People will just have to wait and see. I’m excited for all of it to maybe be put to rest.” The mystery surrounding her character has only fueled more questions, but Sink seems content to keep her cards close to the chest.
The Jean Grey Rumor
One of the most persistent rumors surrounding Sink’s role is that she will take on the role of Jean Grey, the iconic telekinetic mutant from the X-Men franchise. When asked about this possibility, Sink shared that the speculation predated her involvement in Spider-Man: Brand New Day. “That was happening before I even knew that I would be working on this project,” she said with a laugh. “I was like, ‘Wait! What are people talking about?’”
While the idea of Sink playing Jean Grey has captivated fans, it’s important to note that the MCU is known for its surprising casting choices, and the actress’s role in Spider-Man: Brand New Day could very well turn out to be something entirely unexpected. The MCU’s ability to reimagine iconic characters continues to keep fans guessing, especially with X-Men characters entering the franchise in upcoming phases.
