Hayley Atwell will return as Peggy Carter in *Avengers: Doomsday*, marking her first MCU appearance since 2019’s *Avengers: Endgame*. Her comeback signals a deeper exploration of Peggy’s character alongside Steve Rogers, with the film releasing on December 18.

Hayley Atwell is set to return to the Marvel Cinematic Universe (MCU) in the upcoming film *Avengers: Doomsday*, surprising fans at San Diego Comic-Con last weekend. The 44-year-old British actress will reprise her role as secret agent Peggy Carter, a character she first portrayed in 2011's *Captain America: The First Avenger*.

Atwell’s return had been unexpected, as many believed Peggy Carter’s storyline concluded in 2019 with *Avengers: Endgame*. In that film, her love interest Steve Rogers, played by Chris Evans, chooses to live out his life in the 1940s with her, seemingly closing their chapter. However, recent promotional material, including a teaser trailer released earlier this year, revealed that Rogers would be making a comeback, paving the way for Atwell’s reappearance.

During the comic convention, Atwell emphasized the deep connection between her character and Rogers. “You can’t really have Steve without Peggy, or without the longing for Peggy,” she remarked. She also indicated that *Avengers: Doomsday* would explore a new facet of Peggy’s character, highlighting the heightened stakes and the film’s broader existential themes. “It’s such an existential epic of a movie, and you see Peggy in a very different light responding to that,” Atwell explained.

Having portrayed Peggy intermittently for 15 years, Atwell expressed a long-term commitment to the role, stating her hope to continue playing the character over the next decade.

The actress appeared alongside Chris Evans and fellow *Avengers: Doomsday* cast members Robert Downey Jr., Lewis Pullman, David Harbour, Kelsey Grammer, and Pedro Pascal during the convention event in California. Co-director Joe Russo also joined the presentation to discuss aspects of the film, which is slated for release on December 18.

In further MCU casting news, British actor David Jonsson was announced to take on the lead role in *Black Panther 3*, scheduled for release in 2028. Additionally, Ryan Gosling will star in a *Ghost Rider* film the same year, succeeding Nicolas Cage in the iconic biker role.
