Sadie Sink is reportedly preparing for one of the biggest roles of her career yet. The 23-year-old actor, best known for playing Max in Stranger Things, is said to be joining the Marvel Cinematic Universe in the upcoming film Avengers: Doomsday. The movie is expected to release at the end of next year, and filming may begin soon in London, according to recent reports.

A report shared by Deadline has almost confirmed her casting. Producer James Bierman shared new details, saying, “Spider-Man: Brand New Day is scheduled to open on July 31. There has been much speculation about the role Sink has in the Spidey film, and frankly, I do not know the answer. But I do know that she’ll join the cast of the next Avengers picture that shoots here in London later in 2026.” This update has excited fans who have long hoped to see her in the superhero universe.

Earlier, The Hollywood Reporter stated that Avengers: Doomsday would begin principal photography in the summer of 2026. The film is part of Phase Six of the MCU and is slated to arrive in theatres on December 18, 2026. It has already shifted its date once, moving from its earlier May 1, 2026 release. With Robert Downey Jr. confirmed to be a part of the film, expectations are growing rapidly. 

Meanwhile, Sink is currently keeping busy with other major projects. She is filming Spider-Man: Brand New Day, with production expected to continue until mid-December. At the same time, she is travelling for promotions with her Stranger Things co-stars as the series prepares for its highly anticipated fifth season. Her exact character in the Tom Holland-led Spider-Man movie has not yet been revealed, but fans are eager to see what she brings to the role. 

Alongside her film work, Sink is also stepping onto the stage. She will play Juliet in a new production of Romeo & Juliet directed by Robert Icke. Actor Noah Jupe, known for A Quiet Place, will take on the role of Romeo, making the production one of the most anticipated theatre pairings of the year.
