Jean Grey made her Marvel Cinematic Universe debut in "Spider-Man: Brand New Day," which premiered August 1, 2026. The film reimagined an abandoned X-Men story from four decades ago to introduce the character with new powers that differ from her comic book counterpart. Marvel confirmed Jean Grey will return later this year, though actress Sadie Sink is not involved in the role. The film also planted seeds for the MCU's Weapon X Project storyline.
