One of the most anticipated new heroes in the Marvel Cinematic Universe (MCU) could make a significant impact if included in the impressive cast lineup for the upcoming 2026 film, Avengers: Doomsday. Marvel Studios recently unveiled the first wave of actors joining the project during an extensive ceremony on March 26. This early reveal has ignited excitement among fans about what is to come, not just in Avengers: Doomsday, but also in its sequel, Secret Wars, scheduled for 2027. However, there are lingering suspicions that this list of cast members may not be exhaustive, leaving room for the introduction of additional beloved MCU characters.
The Cast Announcement for Avengers: Doomsday Showcases a Diverse Array of Characters
Marvel Confirms 27 Actors for Avengers: Doomsday
Marvel’s cast announcement, which ran for an impressive five and a half hours, confirmed a remarkably diverse and expansive roster for Avengers: Doomsday. The film will feature 27 actors hailing from various Marvel projects, comprising a mix of iconic stars, classic Marvel characters from the pre-MCU era, and new faces yet to appear in the franchise. This extensive lineup hints that Avengers: Doomsday could be the most ambitious installment in the MCU to date, although this may not represent the full extent of the cast.
| Character | Actor | Debut Project | Most Recent Project |
|---|---|---|---|
| Thor Odinson | Chris Hemsworth | Thor (2011) | Thor: Love and Thunder (2022) |
| Invisible Woman (Sue Storm) | Vanessa Kirby | The Fantastic Four: First Steps (2025) | The Fantastic Four: First Steps (2025) |
| Captain America (Sam Wilson) | Anthony Mackie | Captain America: The Winter Soldier (2014) | Captain America: Brave New World (2025) |
| Doctor Doom (Victor Von Doom) | Robert Downey Jr. | Avengers: Doomsday (2026) | Avengers: Doomsday (2026) |
Not All Heroes Have Been Announced for Avengers: Doomsday Yet
Some Heroes Are Not Yet Part of the Doomsday Lineup
Leading up to the cast reveal, discussions suggested that more than 50 actors might be part of the project. However, only 27 were officially announced, indicating that Marvel might be keeping significant surprises under wraps while omitting some notable MCU veterans from the cast. Iconic characters like Mark Ruffalo’s Bruce Banner, Jeremy Renner’s Clint Barton, and Samuel L. Jackson’s Nick Fury are notably absent.
Several fan-favorite heroes, including Brie Larson, Teyonah Parris, Benedict Cumberbatch, and Ryan Reynolds, also seem to be unaccounted for. This could indicate that Marvel intends to provide additional casting announcements as production progresses, possibly including heroes who are available for filming at present. Furthermore, new characters such as Oscar Isaac’s Moon Knight and the Eternals, along with the powerful Jennifer Walters, better known as She-Hulk, have yet to be acknowledged.
The Return of She-Hulk in Avengers: Doomsday Would Be a Smart Move
Fans Are Eager for She-Hulk’s Return in Doomsday
Following recent news that Tatiana Maslany missed the 2025 Comic-Con Liverpool event due to “filming commitments,”speculation arose regarding her possible involvement in Avengers: Doomsday. While Maslany’s name did not appear in the initial cast announcement, her return would be a pivotal leap for both her character and the MCU. Despite a less than stellar debut with She-Hulk: Attorney at Law in 2022, her potential inclusion in the action-packed landscape of Avengers: Doomsday could turn the tide for her character.
The film’s significantly increased budget, along with creative oversight from a more experienced team, promises better visual effects and storytelling for She-Hulk. Her character could be showcased in a more serious light, allowing audiences to connect with her deeper emotional narrative. Fans are hopeful that Tatiana Maslany’s She-Hulk will ultimately make her mark in the MCU’s Phase 6.
