A new social post from Brie Larson has fans speculating whether the Marvel actress is preparing for a role in Avengers: Doomsday. Larson is well known for portraying Carol Danvers/Captain Marvel in the MCU and last appeared in 2023's The Marvels. Dozens of Marvel stars were recently confirmed for the cast of Avengers: Doomsday; however, Larson's chair was noticeably absent.
A new post on Larson's official social Instagram is teasing the actress's next move. The Captain Marvel star recently came off a three-month stint in Elektra on the West End, and her reflective post on her time with the production ends with the hint of a "new chapter" for the actress, which she will reveal on Thursday, May 8:
"Now it's time for a new chapter - more on that on Thursday."
Several things added to the suspicion that this "new chapter" could be Larson's return to the MCU. One is that Avengers: Doomsday is currently filming in London, and the wrap of Larson's West End role potentially frees her up to appear in the film. Another is that Larson's name appeared on Jeff Sneider's recent list of actors rumored to appear in the new Avengers film, hinting that this Thursday announcement could be about Doomsday.
Additionally, Larson revealed she'd met up with Marvel Studios President Kevin Feige before the Avengers: Doomsday reveal at San Diego Comic-Con last year, suggesting they discussed something related to the MCU, but it's unclear what.
There's also a significant chance that Larson's next step isn't Marvel-related. The actress has recently branched into several different areas, including YouTube, theatre, directing, and producing. The specific wording in the comment of this being a "new" chapter for the actress doesn't entirely lend itself to returning to a role she's held in three different MCU movies, but Marvel fans will have to wait until Thursday to find out.
Avengers: Doomsday is the next major crossover film in Phase 6 of the MCU. It is directed by Joe and Anthony Russo, who also directed Avengers: Infinity War and Endgame. The film will feature the return of dozens of MCU stars and is scheduled to hit cinemas on May 1, 2026.
What Is Next for Captain Marvel?
Captain Marvel's next adventure was teased at the end of The Marvels. Captain Marvel teamed up with Kamala Khan (Iman Vellani) and Monica Rambeau (Teyonah Parris) in the movie to stop Dar-Benn from destroying Earth. Unfortunately, this came at a cost. Monica sacrificed herself to close an interdimensional portal that trapped her on the other side, leaving Carol determined to find her.
The post-credits scene for The Marvels reveals Monica awakening in an alternate universe where Kelsey Grammer's Beast is present. As Grammer is one of the cast members confirmed for Avengers: Doomsday, some theories speculate that Monica may be stuck in the same universe as the X-Men, which could tie her into the plot of Avengers 5 and, therefore, also link Captain Marvel to the action.
Captain Marvel was also a key player in the fight in Avengers: Endgame, and considering Sam Wilson is rebuilding the Avengers, Carol Danvers is likely someone he'd want on his side.
