Key Takeaways

What did Tom Holland say about Sadie Sink?

In an exclusive interview with Collider, Holland pointed to Sink when asked which performances fans are not ready for. He highlighted her MCU debut and said she handled the pressure of the character with such grace.

Holland went further on her third-act impact. He said she steals the movie and that the moment is so good it remains a huge spoiler. He also praised a Zendaya scene as among the best he has been part of on the film.

Why is Sadie Sink’s MCU role still a secret?

According to Entertainment Weekly, Sink posted a comical Instagram video teasing theories without naming the part. She confirmed she is not Spider-Man, not Aunt May, and that she is definitely in the film, urging fans to find out in theaters.

Fan theories have included Jean Grey, Gwen Stacy, and Firestar. Murphy’s Multiverse reported that her character name was omitted from official press notes, keeping Marvel secrecy intact ahead of release.

Producers Amy Pascal and Kevin Feige addressed the hush around the casting. Pascal said Sink’s character shares the film’s isolation and alienation theme with figures like Frank Castle and MJ, including denial about the lives they are living.

How was Sadie Sink cast in Brand New Day?

Feige said there was no audition process. Co-producer Emily Fong suggested Sink for a storyline already drafted, and director Destin Daniel Cretton had worked with her before. In that moment, Feige said, they knew it should be her and this character.

Sink previously told Nylon the Marvel brand felt huge, but Holland and the crew made her feel at ease as an outsider stepping in. For more entertainment and market buzz roundups, see our Fintech & Crypto Alerts coverage.
