Input: Question: Did Schaeffer write any other Marvel comics as head writer? Passage:With the September 2018 report of the limited series, one was expected to follow Elizabeth Olsen's Wanda Maximoff / Scarlet Witch. By the end of October, Paul Bettany's Vision was expected to play a large role in the series, which would focus on their relationship. Jac Schaeffer was hired to write the first episode and serve as head writer in January 2019. The series was officially announced and titled in April 2019, with Olsen and Bettany confirmed to be starring. Filming started in November 2019. Teyonah Parris will appear as an adult version of Monica Rambeau. The character was previously portrayed by Akira Akbar, as a child in Captain Marvel (2019). The plot takes place following Avengers: Endgame and leads into Doctor Strange in the Multiverse of Madness (also featuring Wanda) while exploring where the character's alias Scarlet Witch comes from. WandaVision is set to debut in early 2021. At D23, Randall Park and Kat Dennings were announced to reprise their MCU roles as Jimmy Woo and Darcy Lewis in the series. Kathryn Hahn was also cast in an undisclosed role described as "a nosy neighbor". Matt Shakman was announced as the series' director.
