Sadie Sink is getting ready for one of the most important roles of her career, as she is reportedly joining the Marvel Cinematic Universe. The actor, whose performance in Stranger Things has been widely praised, is to feature in Spider-Man: Brand New Day, although an official announcement is still awaited. The movie, which was announced earlier this year, will feature her working with Tom Holland as Peter Parker and Zendaya as MJ. Besides, several returning cast members have also been confirmed. On the other hand, she is also gearing up for the release of the final season of Stranger Things on November 27, 2025.
Sadie Sink Reacts to Joining MCU Rumors
Marvel Studios has kept Sadie Sink’s role under wraps, which is why fans have come up with numerous theories. She said in an interview with Entertainment Weekly that people always think of characters in the context of their looks, but something like hair color can be easily changed for a character. According to her, she gets the speculation but feels that it is based on a very small amount of information.
Sadie Sink also said that she can’t confirm or deny the rumors and that viewers will know the truth only when Marvel gives out the official news. She said that she can’t wait to be able to put down all the guesses once and for all.
Much of the fan discussion has revolved around the idea that Sink might play Jean Grey. When confronted with this question, she responded by saying that those theories came up even before she found out that she was going to be in the film; hence, she was surprised to see how early speculation started and was amused.
More Details
For the unversed, Spider-Man: Brand New Day is in the early stages of production, and the story is kept under wraps for now. Along with Sink, the cast boasts Jacob Batalon, Liza Colon-Zayas, Jon Bernthal, Mark Ruffalo, Michael Mando, Tramell Tillman, and Marvin Jones III. In addition, the actor is rumored to be in Avengers: Secret Wars, which is scheduled to film in London in 2026; therefore, her character’s continuation beyond Spider-Man’s is also expected.
