Sadie Sink Reportedly Joining Avengers: Secret Wars After Mystery Spider-Man Role

by

Hollywood is buzzing with more Marvel news! Reports indicate that Sadie Sink, known for her role in Stranger Things and already cast in the upcoming Spider-Man: Brand New Day, may also appear in the next Avengers movie. Although Marvel hasn’t confirmed anything, the timing and production details suggest it could be Avengers: Secret Wars.

Here’s a breakdown of what we know for sure, what’s happening around it, and what fans are currently guessing about.

Report Claims Sink Is Crossing From Spider-Man to Avengers

Industry reporter Baz Bamigboye first reported that Maya Sink’s appearance in Brand New Day isn’t just a single role. He says she’s also expected to be in the next Avengers film, which is scheduled to be filmed in London in 2026.

Marvel hasn’t officially said anything, and the actress’s role in Brand New Day remains a mystery. The studio has managed to keep this information under wraps despite months of filming.

If the studio is already planning to include her in another movie, it suggests her character will play a bigger role in their future projects than they initially indicated.

Why This Points Directly to Avengers: Secret Wars

Bamigboye’s article does not name the specific Avengers project. However, Marvel’s schedule does.

The movie Avengers: Doomsday has been filmed and is set to come out in December 2026. Currently, Avengers: Secret Wars is the only other Avengers film planned to begin filming in 2026, with a release date in December 2027.

Those dates line up perfectly with the production window referenced in the report.

Although the article doesn’t directly mention it, based on what’s happening in the movie industry, it’s highly probable that Sadie Sink’s next role will be in Avengers: Secret Wars.

A Mystery Role

The Marvel character actor Ben Sinclair is playing in the next Spider-Man movies is still a big secret. Fans have guessed at everything from realistic, down-to-earth roles to characters coming from alternate universes.

Some common fan predictions include:

  • The actual Mary Jane Watson
  • Jean Gray of the X-Men
  • Felicia Hardy/Black Car
  • Gwen Stacy

This information hasn’t been officially confirmed by Marvel. They haven’t revealed the character’s name, appearance, or backstory yet. However, it seems like she could play a significant role in a future, large-scale story.

What This Means for the Multiverse Saga

If Sadie Sink is indeed moving from the film Brand New Day to Avengers: Secret Wars, it suggests her character will play a significant role in the Marvel storyline.

Her character could be someone who appears in different universes, which would make her perfect for a story involving multiple universes colliding. Alternatively, she might be closely connected to Spider-Man’s world, and her story could simply expand within the larger team dynamic.

Both options are important—Marvel doesn’t usually feature up-and-coming actors in several movies without a specific plan in mind.

A Rising Star Who Fits Marvel’s Long Game

Sadie Sink’s popularity has skyrocketed due to her role in Stranger Things and her impressive performances on stage, recently earning her a major award nomination. Marvel signing her for multiple films signals they anticipate she’ll be a key player in the Marvel Cinematic Universe for a long time.

Given Marvel’s recent struggles and their efforts to revamp their projects, this decision appears to be a smart investment in a promising young performer.

What’s Next

Here’s how the release order plays out:

  • Spider-Man: Brand New Day — July 31, 2026
  • Avengers: Doomsday — December 18, 2026
  • Avengers: Secret Wars — December 17, 2027

According to Deadline, we should find out soon if Sadie Sink will be joining the Avengers.
