Spoiler Unveiled at the “Spider-Man: Brand New Day” Premiere

On July 27, 2026, the Dolby Theatre in Hollywood hosted the world premiere of Columbia Pictures’ *Spider-Man: Brand New Day*. During the official red-carpet livestream, streamer Valkyrae asked musician Steve Lacy which character he was most excited to see “without spoiling anything.” Lacy replied that he liked “Jean,” describing her as “the villain” and noting “a reason to her madness.” The clip quickly spread on X, prompting fans to connect “Jean” with Jean Grey, the telekinetic mutant from the X-Men franchise, and to infer that actress Sadie Sink—who had been kept out of press interviews—was portraying that character.

Rumors had circulated for months that Sink would join the Marvel Cinematic Universe as Jean Grey, coinciding with Marvel’s announced integration of the X-Men properties. The studio’s marketing campaign deliberately concealed Sink’s role, presenting her as a “mystery” character to heighten intrigue. Lacy’s song “oh yeah?” appears on the film’s soundtrack, explaining his presence on the carpet.
