# Spider-Man: Brand New Day confirms Jean Grey debut > Live situation record from CLSTR: https://clstr.news/situations/marvel-spider-man-role-secrecy > Updated: 2026-09-13T21:39:04.000Z. Sources: 254. Developments: 16. Marvel Studios confirmed on 30 July 2026 that Sadie Sink portrays mutant Jean Grey in Spider-Man: Brand New Day, the franchise’s fourth solo film, which opened worldwide on 31 July 2026. The studio concealed the casting with the fake script codename “Denim Red” to preserve the opening-weekend experience. In the film, Grey uses telepathic powers to possess individuals while searching for her sister, Sara, who was taken by the Department of Damage Control. After being captured by the department's chief, Bill Metzger, Grey assists Spider-Man in surviving a gunshot before fleeing the city. The film also introduces Samara Weaving as Emma Frost. Spider-Man: Brand New Day earned roughly $927 million in its first weekend and surpassed $1.68 billion globally by mid-August. Following debates regarding the character's violence, screenwriters Erik Sommers and Chris McKenna clarified that, “technically, she’s not responsible for any deaths.” Sink has drawn attention for portraying Grey as a villainous figure reacting to trauma rather than acting out of inherent malice. At the Disney D23 event, Marvel officially announced Sink’s involvement in the upcoming X-Men reboot, scheduled for 5 May 2028. Directed by Jake Schreier, the film aims to establish a new narrative foundation by focusing on a compact team of core heroes, with reports indicating Magneto and Gambit will be absent from the initial lineup. The confirmed cast includes Kit Connor as Cyclops, Christopher Abbott as Professor Charles Xavier, Samara Weaving as Emma Frost, Inde Navarrette as Rogue, Maya Boyd as Storm, and Adam Driver as Mister Sinister. Regarding character development, Navarrette has expressed commitment to portraying Rogue with an accurate Mississippi accent, utilizing her Texas upbringing to honor the character's Southern roots. Discussions regarding the roster have also included potential interest in Silver Age era mutants such as Mimic (Calvin Rankin). ## Claims - Sadie Sink is cast in Spider‑Man: Brand New Day.
