How ‘WandaVision’ Sets Up ‘Doctor Strange In The Multiverse of Madness’ 03/05/21 AT 5:42 PM The “WandaVision” finale sets up the next “Doctor Strange” movie in a big way. The Disney+ show had only one direct reference to the Sorcerer Supreme, but it’s clear that he’s connected to Wanda Maximoff’s future—but she might be the antagonist in “Doctor Strange in the Multiverse of Madness.” “The Scarlet Witch is not born, she is forged,” Agatha Harkness (Katherine Hahn) explains to Wanda (Elizabeth Olsen). “She has no coven, no need for incantation. Your power exceeds that of the Sorcerer Supreme. It's your destiny to destroy the world.”
