Sadie Sink Cast as Jean Grey in Upcoming Spider-Man Film

Actress Sadie Sink, known for her role in "Stranger Things," has been cast as mutant telepath Jean Grey in the upcoming Spider-Man solo film "Spider-Man: Brand New Day." The character, previously portrayed by Sophie Turner and Famke Janssen in the X-Men franchise, will appear later in the movie and possesses mind-control abilities that allow her to transfer between bodies within a limited range.

In the film’s plot, Grey seeks a missing sister, Sara, who was captured while the two practiced their shared psionic powers. Sara’s involvement with Damage Control’s director leads to a device intended to map Grey’s brainwaves, a project that ends with Sara’s death. Peter Parker intervenes, taking a bullet intended for Grey, after which she accesses his mind to aid his recovery.

The introduction of Jean Grey signals Marvel’s expansion of mutant characters into the MCU, a development that follows the studio’s acquisition of 20th Century Fox’s X-Men properties. The ending of the film hints at Grey’s significant power level, drawing comparisons to other high-profile characters such as Wanda Maximoff.

"We’re excited to bring Jean Grey into the Spider-Man universe and explore how her abilities intersect with Peter Parker’s story," a Marvel spokesperson said.

The casting aligns with Marvel’s broader strategy to integrate X-Men elements into upcoming projects, including the anticipated "Deadpool & Wolverine" release.
