Brie Larson will not appear as Captain Marvel in the upcoming film Avengers: Doomsday, according to popular YouTuber Nerdrotic. This unexpected absence marks a significant shift in Marvel Studios’ direction for the character, especially as the franchise builds toward the highly anticipated Avengers: Secret Wars.
Nerdrotic, known for scooping casting updates, stated clearly that Larson’s Captain Marvel is not part of this film set to release on December 18, 2026. Despite rumors and official confirmations of many other cast members, the absence of Larson signals a major change in Marvel’s cinematic universe plans.
Details on Brie Larson’s Absence and Related Casting News
Nerdrotic revealed on Twitter,
“There is no Brie Larson Captain Marvel in Avengers: Doomsday,”
directly dispelling fan speculation. When asked if Ironheart would appear, he also replied simply, “Nope.” However, he confirmed the presence of Pedro Pascal and suggested that Tessa Thompson might also return, possibly linked to the upcoming Secret Wars event.
Marvel has announced 27 official cast members for Avengers: Doomsday, with rumors including up to 33 more actors. Brie Larson had been considered among these, but this new information contradicts those reports, indicating that Captain Marvel will be sidelined in this phase of the MCU.
The Impact of Brie Larson’s New Look on Fan Speculation
Earlier in 2025, Brie Larson shaved her head for a theater role and later showcased a short blonde hairstyle reminiscent of her appearance in Avengers: Endgame. This change fueled rumors among fans expecting her to reprise her role as Captain Marvel in upcoming Avengers projects. Despite the speculation, Nerdrotic’s update dampens hopes of her return, suggesting Marvel may be moving away from the character after years of inconsistent involvement.
Ironheart’s Cancellation and Challenges in Marvel’s Streaming Content
Nerdrotic also denied any involvement of Ironheart in Avengers: Doomsday. The Disney+ series featuring Riri Williams as the lead was recently canceled amid poor reception and low viewership. This cancellation reflects broader difficulties Marvel has faced with its streaming projects, where rising production costs and waning audience interest have impacted several shows.
In response to these issues, Disney is reportedly shifting strategies by reducing content output and trimming budgets, exemplified by the upcoming Daredevil: Born Again, which follows a leaner production approach.
The Marvels’ Financial Struggles and Influence on Marvel’s Direction
Brie Larson’s last Marvel film, The Marvels, performed below expectations and became Marvel Studios’ lowest-grossing production, earning only $206 million globally against a $270 million budget. Despite featuring Iman Vellani as Ms. Marvel and Teyonah Parris as Monica Rambeau, the movie failed to attract the usual large audiences, potentially impacting future character involvement decisions.
This disappointing box office, coupled with mixed reviews, appears to have influenced Marvel’s decision to limit the focus on characters linked to The Marvels as they plan for a reboot of the franchise lineup.
Disney’s Admission of Losing Male Viewers and Its Effect on Marvel’s Strategy
Disney has publicly acknowledged that both Marvel and Star Wars franchises have alienated a portion of their male audience over recent years. Internal discussions reveal an effort to regain these lost fans after a prolonged decline in engagement across these properties.
This acknowledgment is significant, as it explains recent casting changes and the creative redirection Marvel is taking. The company seems focused on restoring the core male demographic that fueled the franchise’s previous successes, likely influencing which characters receive screen time moving forward.
Marvel’s Attempt to Reinvent the Franchise Moving Forward
After setbacks such as The Marvels’ poor performance, the cancellation of Ironheart, and now Brie Larson’s absence from Avengers: Doomsday, Marvel appears to be undergoing a substantial reset. The studio is realigning its roster to spotlight fan-favorite characters and performers who can help reestablish excitement for this expansive universe.
Avengers: Doomsday and Secret Wars represent crucial moments for Marvel to regain momentum and audience trust. While it remains unclear if Captain Marvel will ever reappear, this phase signals the potential conclusion of Larson’s role as a cosmic lead within the MCU’s evolving narrative.

Well Pedro is in it for sure. I assume Tessa Thompson will be in it, or Secret Wars for sure. pic.twitter.com/SBknBIyC7c
