Rumours about the Marvel's X Men upcoming movie have been crazy after Jeff Sneider, also known as "The InSneider", reveals on "THE HOT MIC", John Rocha's podcast's newest episode that he's got a lead from one of his old sources saying that 'Stranger Things' actress Sadie Sink is first in line for the Jean Gray role.
Although the Marvel's X Men seems pretty far, given the big movie schedule they have and the lot of unreleased titles for the upcoming years, Marvel is not new to the cameos or the small umprompted appearances from new characters in their movies, so it wouldn't be a shocker if they decided to start casting the upcoming mutants and show them in the upcoming movies.
That way they can test people's reaction and make changes accordingly, and start tying loose ends and giving explanations before they introduce mutants to the MCU, something they just started doing with Ms. Marvel's TV Show.
If the rumours about Sadie Sink playing Jean Gray are true, it looks like we're gonna be getting a younger version of the mutants, but in the meantime we can only wait for an official announcement or more rumours to come along and give away who else is going to play the iconic team, or even who is going to direct the movie.
