Avengers: Doomsday has such a big cast, it took a warehouse full of chairs and a five-and-a-half hour livestream to reveal all of them, starting from Chris Hemsworth and revealing 26 more names until Robert Downey Jr., himself showed up. But clearly, that wasn’t the entire cast, as more mysterious characters were introduced, including the multiple color-changing Latverian witches.
At Marvel’s massive Hall H presentation at San Diego Comic-Con this year, yet another name was added to the list: Peggy Carter, Steve’s love interest who he chose to stay with in the past during Avengers: Endgame. But her involvement means more than just seeing Hayley Atwell in period costume again — it could actually confirm a longtime fan theory.
