Avengers: Doomsday is going to be a huge movie, and just got bigger. Marvel Studios revealed a brand new member of the cast, an MCU star who was last seen in Avengers: Endgame.
What former MCU star will return in Avengers: Doomsday?
During Marvel Studios’ San Diego Comic-Con 2026 panel, the company brought out a ton of stars from the upcoming ensemble Avengers movie. During that time, it was revealed that none other than Hayley Atwell will be returning to the upcoming MCU movie.
Of course, Atwell has played Peggy Carter, Steve Rogers’ (Chris Evans) love interest and a bona fide hero in her own right, throughout the MCU. She was last seen in Endgame, where Rogers went back in time to stay there and live out his life with Carter.
With much of the upcoming Doomsday rumored to center around Chris Evans’ return as Captain America, it would make sense that Atwell is involved in some way, and now we know for sure she is. Speaking to DiscussingFilm after the panel, Atwell called the movie an “existential epic,” and said we’ll see Peggy “in a very different light” as a result.
“Universes collide and the Multiverse Saga begins its final chapter in Marvel Studios’ Avengers: Doomsday. Beloved heroes from three distinct universes will be set on a deadly collision course and ultimately face an existential threat unlike anything they’ve ever encountered. This epic film will lay the foundation for the future of the Marvel Cinematic Universe,” reads the film’s official synopsis.
The film is set to feature a huge cast, which includes Chris Hemsworth’s Thor, Pedro Pascal’s Reed Richards, Vanessa Kirby’s Invisible Woman/Sue Storm, Anthony Mackie’s Captain America, Sebastian Stan’s Bucky Barnes/Winter Soldier, Letitia Wright’s Shuri/Black Panther, and Paul Rudd’s Ant-Man, among others. Avengers: Doomsday is set to release on December 18, 2026. Avengers: Secret Wars is set to release a year later on December 17, 2027.
