During the broadcast of "Wanda's Vision" last year, Agatha Harkness, played by Catherine Hahn, quickly became a fan favorite MCU character, so Marvel also launched her solo spin-off series Agatha: Harkness House.
Agatha: House of Harkness is still in the early stages of development and is expected to begin filming in October 2022, so there's not much information about the plot of the series and the characters fans can expect. However, in the trailer for the upcoming Doctor Strange 2: Crazy Multiverse, Wanda will revisit Westview, suggesting that Agatha may also appear, and that her spin-off background may be established there.
With Doctor Strange 2: Crazy Multiverse approaching, an interview with Entertainment Weekly, Catherine Hahn also brings good news to fans who are anxiously waiting to see the Witch of Westview again.
Although Agatha: Harkness House is far from complete, Hahn says what she sees from how things unfold "exactly what [she] wanted and dreamed of."
Hahn admitted that she had learned about the entire plan for the project when Wanda Vision first launched, which proves that Marvel is happy to include Harkness in some of the big MCU events.
With Agatha: Harkness House planned to be made in eight months' time, will Doctor Strange 2: Crazy Multiverse be linked to the show? At the end of Wanda's Visions, Wanda exiles Agatha, and considering that Wanda is most likely out of control in Doctor Strange 2, it is possible that Agatha was released.
Catherine Hahn's statement that "exactly what [she] wants and dreams for" bodes well and suggests that Agatha's chances of getting involved in the MCU are just around the corner.
