Hayley Atwell (who will reprise the role of Peggy Carter as she becomes Captain Britain) has shared the previously released trailer to her Instagram account along with the following: “Coming summer 2021 #disneyplus an alternative narrative in a parallel universe… a position of power that Peggy Carter is fully equipped for #iknowmyvalue 🇬🇧👊🏼”

That’s an interesting description, and indicates that all these character inhabit the same Earth rather than different ones. This leaves us to wonder what singular incident led to this unrecognisable world being created where T’Challa became Star-Lord and The Winter Soldier battles a zombie Captain America.

A synopsis for the series was shared during last year’s Disney Investor Day, revealing: “‘What If…?’ flips the script on the MCU, reimagining famous events from the films in unexpected ways.”

“Coming to Disney+ in summer 2021, Marvel Studios’ first animated series focuses on different heroes from the MCU,” it continues, “featuring a voice cast that includes a host of stars who reprise their roles. The series is directed by Bryan Andrews; Ashley Bradley is head writer.” [Source]
