Disney’s largest biennial event, D23 Expo, was recently held on August 23-25, 2019 in Anaheim, California. Included in the expo’s slate is a slew of new revelations and lineups for the Marvel Cinematic Universe.

During the Marvel Studios panel, Director Bryan Andrews took the stage to tell the audience more about the new Disney+ animated series “What If…?”, an anthology series that explores moments in the MCU had it happened differently from the canon.

Confirming her return to the MCU is Hayley Atwell, reprising her role as Peggy Carter. But in the series, Carter will be donning the iconic vibranium shield and receiving the Super Soldier Serum, taking on the moniker of Captain Britain.

The show’s footage presented on stage also confirms the introduction of Marvel Zombies in this alternate retelling of the Captain America origin.

It was previously confirmed in SDCC that Jeffrey Wright will be taking on the role of The Watcher, with MCU alums also returning to reprise their respective roles as voice actors for the animated series.
