WandaVision” head writer Jac Schaeffer has signed a three-year overall deal TV deal with Marvel Studios and 20th Television.

Under the deal, Schaeffer will develop projects for both Marvel Studios and 20th Television. Projects for Marvel Studios will go to Disney Plus, while projects for 20th TV will be developed for all platforms.

Schaeffer created “WandaVision” for television and also served as head writer and executive producer. She is also known for writing, directing, and producing the feature “TiMER” and also wrote the animated short “Olaf’s Frozen Adventure” and the feature “The Hustle” starring Anne Hathaway and Rebel Wilson. She also worked on the story for the upcoming Marvel feature “Black Widow,” which will be released in theaters and on Disney Plus on July 7.

She is repped by Writ Large, Verve, and Paul Hastings.

“WandaVision” was the first Marvel Cinematic Universe series to debut on Disney Plus, launching on the streamer in January. The show starred Elizabeth Olsen as Wanda Maximoff, a.k.a. Scarlet Witch, and Paul Bettany as Vision, with the pair reprising their roles from the MCU. The show received strong acclaim upon its release, holding a 91% critical approval rating on Rotten Tomatoes.

Variety‘s Caroline Framke wrote in her review: “Despite its character and dialogue beats, ‘WandaVision’ isn’t a sitcom; it’s a sinister thriller wearing respectable clothes and an unnervingly bright grin. It’s ‘Pleasantville,’ if ‘Pleasantville’ opened with the characters stuck inside the black and white television.”

Since “WandaVision” debuted, fellow MCU show “The Falcon and The Winter Soldier” has also debuted on Disney Plus, while “Loki” is set to drop in June.
