#Captain Carter & Chadwick Boseman’s Final Performance as T’Challa (VIDEO)

There’s a multiverse of infinite possibilities in the world of Marvel, and the newest offering, its first-ever animated series What If…? examines some of them.

Disney+ has released a new trailer and poster for the upcoming series launching on Wednesday, August 11. (Disney+ moved the release day for its originals to Wednesdays from Fridays following another Marvel series’ premiere, Loki.) What If…? reimagines famous events from films in the MCU and features fan-favorite characters including Peggy Carter, T’Challa, Doctor Strange, Killmonger, and Thor.

This is Chadwick Boseman’s final performance as T’Challa, and he can be seen quite a bit — with the Guardians of the Galaxy — in the trailer below. Also glimpsed: Killmonger coming to Tony Stark’s aid, Peggy Carter as a version of Captain America, and much more.

As the trailer tells us, reality is changeable and anything’s possible: “Every universe is different, each one unique.” See just how much can change:

Jeffrey Wright’s the Watcher narrates. “I observe all that transpires here. But I do, cannot, will not interfere,” he explains.

Among the MCU stars — in addition to Boseman — whose voices you’ll hear in What If…? are: Chris Hemsworth (Thor), Tom Hiddleston (Loki), Michael B. Jordan (Killmonger), Samuel L. Jackson (Nick Fury), Mark Ruffalo (Bruce Banner/Hulk), Jeremy Renner (Clint Barton/Hawkeye), Sebastian Stan (Bucky Barnes/Winter Soldier), Josh Brolin (Thanos), Karen Gillan (Nebula), and Hayley Atwell (Peggy Carter).

Bryan Andrews directs the new series. AC Bradley is head writer.
