While Marvel has remained tight-lipped about the movie's full cast, Secret Wars is expected to bring together heroes from across the MCU, making it one of the franchise's most ambitious projects to date. For Sink, it could mark her biggest blockbuster appearance yet.
Untitled X-Men Movie (2028)
The Marvel Cinematic Universe officially ushers in a new mutant era with the Untitled X-Men Movie (2028), directed by Jake Schreier. Serving as a ground-up reboot, the film places Sadie Sink front and center as a central powerhouse and leader of the legendary team. Starring alongside Kit Connor as Scott Summers (Cyclops), the duo will bring dynamic youth and gravitas to the iconic superhero faction. Together, they redefine Marvel’s iconic heroics for a new generation.
The Marriage Plot (2026)
Sadie Sink is also set to star in The Marriage Plot, a television miniseries currently in pre-production. Based on Jeffrey Eugenides' acclaimed novel, the project follows a group of young graduates navigating love, relationships, and identity in the years after college.

John Proctor Is the Villain
