Speaking to The Hollywood Reporter, Sink candidly admitted that keeping secrets for Spider-Man: Brand New Day proved even more challenging than safeguarding spoilers for the final season of Stranger Things.

Though Marvel Studios and Sony Pictures maintained official silence, speculation about Sadie Sink's role as Jean Grey has been widespread. Reports from the set mentioned Sink wearing green and yellow, an apparent nod to Marvel Girl's classic comic book costume, and her hair and eye colour were reportedly altered for the role, fueling the rumours. However, her role remains officially unconfirmed by the studios.
Sink expressed immense excitement about joining the franchise, noting her long-standing admiration for Spider-Man and Tom Holland's portrayal. She also shared that working with director Destin Daniel Cretton again, whom she collaborated with on the 2017 film The Glass Castle when she was around 14 years old, felt like a "full-circle moment".
Spider-Man: Brand New Day picks up four years after the events of Spider-Man: No Way Home, with Peter Parker (Tom Holland) operating as Spider-Man in a world that has forgotten his existence. The film sees Peter Parker grappling with his isolation and the emotional toll of seeing his friends, MJ (Zendaya) and Ned Leeds (Jacob Batalon), move on without him. He faces a powerful, unseen new threat while his own superpowers begin to undergo a dangerous evolution, leading him to seek help from Bruce Banner/The Hulk (Mark Ruffalo). Jon Bernthal also reprises his role as Frank Castle/The Punisher. ‘Spider-Man: Brand New Day’: Football ‘GOAT’ Lionel Messi Enters Tom Holland’s Spider-Verse in Epic Crossover Promo (Watch Video).
