The Avengers: Doomsday cast announcement in March revealed 26 actors plus the already confirmed Robert Downey Jr. This large ensemble is bigger than most films typically have, but many fans have noticed the absence of some expected names, including Brie Larson.
Despite this, some Marvel fans speculate that Carol Danvers, also known as Captain Marvel, will appear in the upcoming Avengers movie. This theory gained traction following a recent photo of Brie Larson shared on social media.

The image shows Larson in a voting booth, just having completed her voting. However, she is wearing a hood that seems to intentionally conceal a wig, which sparkled speculation among fans.
Many comments suggest that the photo hints at Larson undergoing additional filming for Avengers: Doomsday, as the hidden wig resembles Captain Marvel’s hairstyle. The effort to conceal the wig is seen as an attempt to avoid revealing spoilers, a tactic commonly used by Marvel Studios.
This reasoning explains why Larson might be covering the wig so carefully—fans believe it signals her character’s presence, despite official cast lists.
Fans interpret Brie Larson’s hidden wig in a candid photo as a subtle hint of her unannounced role as Captain Marvel in Avengers: Doomsday, reflecting Marvel’s secretive filming practices.
