WandaVision

Elizabeth Olsen and Paul Bettany reprise their respective roles as Wanda and Vision from the film series, with Debra Jo Rupp, Fred Melamed, Kathryn Hahn, Teyonah Parris, Randall Park, Kat Dennings, and Evan Peters also starring. By September 2018, Marvel Studios was developing several limited series for Disney+ centered on supporting characters from the MCU films such as Wanda and Vision, with Olsen and Bettany returning. Schaeffer was hired in January 2019, with the series officially announced in April, and Shakman joining in August. The production used era-appropriate sets, costumes, and effects to recreate the different sitcom styles that the series pays homage to. Filming began in Atlanta, Georgia, in November 2019, before production halted in March 2020 due to the COVID-19 pandemic. Production resumed in Los Angeles in September 2020 and wrapped that November.

WandaVision premiered with its first two episodes on January 15, 2021, and ran for nine episodes, concluding on March 5. It is the first series, and the beginning, of Phase Four of the MCU. The series received praise from critics for its homages to past sitcoms and for the performances of its cast, especially those of Olsen, Bettany, and Hahn, though there was criticism for the finale. It was widely discussed and analyzed by fans based on various popular theories, as well as by commentators for its exploration of grief and nostalgia. The series received numerous accolades, including 23 Primetime Emmy Award nominations, winning three. Olsen reprised her role in the film Doctor Strange in the Multiverse of Madness (2022), which continues Wanda's story from WandaVision. Two spin-off series, Agatha All Along which focuses on Hahn's Agatha Harkness and premiered in September 2024, and VisionQuest which focuses on Bettany's Vision and premiered in October 2026, form a trilogy with WandaVision.
