Although each episode takes on the tone and setting of a different classic sitcom, one thing has remained constant throughout the Disney+ series WandaVision: Kathryn Hahn’s show-stealing performance as Agnes, the nosey neighbor. In every new incarnation of domestic farce experienced by the Scarlet Witch Wanda Maximoff (Elizabeth Olsen) and her husband Vision (Paul Bettany), Agnes has burst in as a chaotic, but ultimately good-hearted, force.
