The Avengers: Doomsday cast announcement in March included 26 actors, plus the already-confirmed Robert Downey Jr. This lineup is larger than most films usually have. Despite the extensive cast, some notable names were absent, including Brie Larson. However, some Marvel fans suspect that Carol Danvers, aka Captain Marvel, will still appear in the upcoming Avengers movie.
This speculation grew after a recent photo surfaced, shared by MCUFilmNews, showing Brie Larson in a voting booth. She had just finished voting but made sure the hood over her head concealed a wig she was wearing, which she subtly points out in the bottom right corner of the image:

At first glance, one might wonder why Larson would want to hide her wig. However, the comments on the post reveal many fans believe this is a sign she is filming additional scenes for Avengers: Doomsday. They argue she is hiding Carol Danvers’ iconic hairstyle to avoid spoilers.
Fans reason that going to such lengths to conceal a wig aligns with Marvel Studios’ tradition of protecting their secrets. It seems likely Larson is back in character, even if unconfirmed officially.
Many fans interpret the subtle photo cues as a hint of Larson’s involvement despite no formal confirmation. The effort to hide her wig has fueled theories that Captain Marvel’s presence is a surprise part of the movie’s story.
