Stranger Things star Sadie Sink has a role in Marvel and Sony’s Spider-Man 4. According to Coming Soon, her character in the film remains unknown. However, fans have made their own theories about who she could potentially be playing as. They believe that she could be playing X-Men‘s Jean Grey, Gwen Stacy, or possibly a complex version of Mary Jane Watson.
According to industry insider Jeff Sneider, Marvel’s agreement with Sony requires each Spider-Man film to feature a significant MCU character, a criteria set by appearances from Robert Downey Jr.‘s Iron Man in Homecoming, Samuel L. Jackson’s Nick Fury in Far From Home, and Benedict Cumberbatch’s Doctor Strange in No Way Home. If Sink were cast as Jean Grey, it could fulfill this requirement. However, Sneider also points out that casting Sink as Jean Grey might involve complications, including potential fees to producer Lauren Shuler Donner, who has been associated with the X-Men films. As a result, it seems less likely that Sink will take on this role.
If Sink isn’t playing Jean Grey, other characters she could portray include Gwen Stacy, Mary Jane, or perhaps Firestar, a mutant with connections to Spider-Man, or Felicia Hardy, also known as Black Cat, a key Spider-Man character and potential love interest. Fans are eager for Black Cat’s introduction to the MCU, especially following her brief appearance in The Amazing Spider-Man 2. As of now, Marvel Studios has not officially confirmed who Sink will be playing.
