For characters like Scarlet Witch or Agatha Harkness, played by Kathryn Hahn, much of their on-screen magic comes from CGI, leaving the actors to rely solely on imagination during filming. Even major Marvel stars like Chris Hemsworth, who plays Thor, must act out scenes involving powers that are added later through digital effects. Olsen also revealed that while promoting Doctor Strange in the Multiverse of Madness, she had never met co-star John Krasinski, despite sharing a scene with him, further highlighting the disjointed nature of filming with visual effects.
Though Olsen hasn’t officially returned as Scarlet Witch, Marvel fans were given a subtle nod in Agatha All Along, where Agatha Harkness finds Wanda Maximoff’s body, hinting at her possible death. While Wanda’s return remains uncertain, her involvement in the first episode has sparked speculation that she might appear later in the series. For now, fans can catch Olsen’s last appearance as Scarlet Witch in Doctor Strange in the Multiverse of Madness, streaming on Disney+.
