Zack Sharf Digital News Director Hayley Atwell is currently kicking butt in “Mission: Impossible – Dead Reckoning Part One,” but the Tom Cruise-led action tentpole is not the actor’s first go-around with a Hollywood mega-franchise. Atwell joined the Marvel Cinematic Universe as Peggy Carter in 2011’s “Captain America: The First Avenger.” It’s a role she would flesh out in two seasons of ABC’s “Agent Carter” series, before lending her voice to an alternate version of Peggy in Marvel’s Disney+ series “What If…?” Atwell’s Peggy Carter is a passionate fan favorite among Marvel lovers, which is why fans were so delighted when the character popped up as an alternate Captain America in 2022’s “Doctor Strange in the Multiverse of Madness” and then made furious when she was almost immediately killed off by Scarlet Witch (Elizabeth Olsen). In a new interview on the “Happy Sad Confused” podcast, Atwell called the cameo “a frustrating moment.”
