Sadie Sink Turns MCU Secrecy Into Public Spectacle

During the Spider-Man: Brand New Day press tour, Sadie Sink refused to reveal her MCU role as Jean Grey, exemplifying Marvel’s secrecy and spoof-proof promo culture; the veil finally lifted when Steve Lacy casually spoiled Grey’s identity at the LA premiere, illustrating the reach of spoiler culture. Sink’s performance anchors the film’s emotional core, and Brand New Day intentionally seeds an expanded X‑Men presence in the MCU, contributing to a blockbuster that reached $1 billion faster than all but Avengers: Endgame.
