Jake Schreier, director of the X-Men for the Marvel Comics Universe, has enlisted "Beef" creator Lee Sung Jin and "The Bear" co-showrunner Joanna Calo to write the latest draft of the upcoming superhero adventure. This move reunites Schreiers, who have previously worked on "The Hunger Games: The Ballad of Songbirds and Snakes" and "Now You See Me, Now You Don't" for the film. This is significant as it marks the mutants’ solo debut in a Marvel Studios-produced movie.
