Sadie Sink turned the Spider-Man: Brand New Day promotional campaign into one long guessing game, as her role was kept a secret all the way until the movie hit theaters.

Sadie Sink plays Jean Grey in the new movie
After much speculation and fan theories, we now know that Sadie Sink is Jean Grey.

Who is Jean Grey?
According to Marvel, Jean Grey is “an extraordinary telepath and telekinetic” and a founding member of the X-Men. Professor Charles Xavier discovers her immense potential at a young age, training her to become an omega-level mutant.
She’s perhaps best known for her connection to the Phoenix Force, a cosmic entity that makes her one of the most powerful characters in the Marvel Universe.
Has Jean Grey appeared in the Marvel movies before?
Jean Grey was previously portrayed by Famke Janssen in Fox’s original X-Men movies and by Sophie Turner in the prequel films, making Sadie Sink the first actress to play the character in the Marvel Cinematic Universe.
What does this mean for the MCU?
Introducing Jean Grey is a major milestone for the MCU, as she’s one of Marvel’s most important mutant characters and a founding member of the X-Men.
Although Marvel hasn’t announced its full plans yet, Marvel Studios president Kevin Feige has already confirmed years ago that a new era centered on the X-Men is in development, and there have been reports about casting as of last year, making Jean Grey’s debut one of the franchise’s biggest steps toward that future.
