As we first reported on ComicBookMovie.com, Marvel Studios has shared a cast list for the upcoming third and final season of What If...?, and Jeffrey Wright's Watcher looks set to be joined by another A-List lineup of Marvel Cinematic Universe talent.
We heard some time ago that season 3 would add some key Phase 4 characters to the mix, and that's evident from the presence of Kingo, Shang-Chi, Kate Bishop, Moon Knight, and Agatha Harkness, among others.
There aren't many surprises beyond that, though we are intrigued to see what the likes of Sonny Burch and Arishem the Judge bring to the table.
What If...? will also deliver some big MCU debuts, with Barbie star America Ferrera and Harry Potter icon Jason Isaacs among the guest stars set to appear in the 8-episode series.
