Kathryn Hahn is ready to walk the Witch’s Road in Agatha All Along trailer

The true identity of nosy next-door neighbor Agatha—played to perfection by Kathryn Hahn—was the big reveal of 2021’s WandaVision, even inspiring a meta-jingle that naturally went viral. Now Hahn is bringing the character back for her own standalone adventure with Agatha All Along. Based on the first trailer, it looks like a lot of dark, spooky fun, just in time for the Halloween season. The nine-episode series is one of the TV series in the MCU’s Phase Five, coming on the heels of Secret Invasion, Loki S2, What If…? S2, and Echo.

(Spoilers for WandaVision below.)

WandaVision was set immediately after the events of Avengers: Endgame (but before Spider-Man: Far From Home), with newlyweds Wanda and Vision starting their married life in the town of Westview, New Jersey. Wacky hijinks ensued as the couple tried to lead a normal life while hiding their superpowers from their neighbors—especially Hahn’s nosy Agnes. Each episode was shot in the style of a particular era of sitcom television, from the 1950s through the 2000s. The couple noticed more and more jarring elements—a full-color drone, a voice calling out to Wanda over the radio, neighbors briefly breaking character—hinting that this seemingly idyllic suburban existence might not be what it seemed.

We learned that a grief-stricken Wanda had inadvertently locked the entire town in a reality-warping Hex, with the residents forced to play their sitcom “roles” and adhere to Wanda’s “script,” creating the happily ever after ending she never got with Vision. But the hijinks weren’t all due to Wanda’s powers. Agnes turned out to be a powerful witch in her own right named Agatha Harkness, who had studied magic for centuries and was just dying to learn the source of Wanda’s incredible power. Wanda’s natural abilities were magnified by the Mind Stone, but Agatha realized that Wanda was a wielder of “chaos magic.” She was, in fact, the Scarlet Witch. In the finale, Wanda trapped Agatha in her nosy neighbor persona while releasing the rest of the town.

Agatha All Along has been in the works since 2021, officially announced in November of that year. There were numerous title changes, culminating this May with my personal goofy favorite: Agatha: The Lying Witch with Great Wardrobe (a nod to C.S. Lewis). It briefly appeared on the Marvel Twitter account before being taken down, and Disney soon revealed that the various name changes were “orchestrated by [Harkness] as a way of messing with Marvel fans.” Head writer Jac Schaeffer (who also created WandaVision) has said that the series would follow Agatha as she forms her own coven with “a disparate mixed bag of witches… defined by deception, treachery, villainy, and selfishness” who must learn to work together. And apparently we can expect a few more catchy tunes.
