WandaVision is a 2021 live-action TV series developed for Disney+ spinning directly out of the Marvel Cinematic Universe based on the characters of Scarlet Witch and Vision.
The show continues the romantic pairing Elizabeth Olsen's Wanda Maximoff (The Scarlet Witch) and Paul Bettany's Vision. The show will also feature the adult version of Monica Rambeau (played by Teyonah Parris), a character who previously appeared as a child in the Captain Marvel movie. Other MCU alumni in the cast include Kat Dennings (Thor) and Randall Park (Ant-Man and the Wasp). Kathryn Hahn also stars.
Matt Shakman of Game of Thrones fame is directing the series, which is written by Jac Schaeffer, who also penned the Black Widow script.
Disney+ provides this synopsis for the show: The series is a blend of classic television and the Marvel Cinematic Universe in which Wanda Maximoff and Vision--two super-powered beings living idealized suburban lives--begin to suspect that everything is not as it seems.
Word is that the events of this show will lead directly into the Doctor Strange sequel which will also feature The Scarlet Witch.
