‘Agatha All Along’ trailer sees Kathryn Hahn channeling Wicked Witch of the West

It’s time to go “down, down, down the Road, down the Witches’ Road.”

Disney fans attending the D23 Expo in Annaheim, Calif., this weekend could hear those words performed as part of a new song composed for Agatha All Along through an activation set up at the convention center. Now the tune, and the Witches’ Road itself, becomes more clear in the new full-length trailer for the WandaVision sequel series that dropped during a big Marvel presentation Friday night.

Some of the stars, including Kathryn Hahn, Joe Locke, Sasheer Zamata, and Ali Ahn, were on hand with showrunner Jac Schaeffer to preview the upcoming series, which sees the return of Hahn’s Agatha Harkness.

The centuries-old witch breaks free from the spell that Wanda Maximoff (Elizabeth Olsen) used to trap her in Westview during the events of WandaVision. Left without her powers, she’s determined to regain her magic by traversing the Witches’ Road, a mystical yet dangerous place that grants any witch that can survive its trials with their deepest desire.

She just needs a coven in order to get to the end. Locke plays a mysterious teen who helps Agatha escape her curse, Zamata plays Jennifer Kale, Ahn plays Alice Wu-Gulliver, Patti LuPone plays divination witch Lilia Calderu, Aubrey Plaza plays warrior witch Rio Vidal, and Debra Jo Rupp returns from WandaVision as Sharon Davis — all members of the band of coven-less witches gathered to traverse the Road.

Each trial, it seems, comes with a new setting and a new look for the witches. The coven sports new sembles, including a 1970s flower-child vibe for one such trial. In another scene, Agatha is transformed into the Wicked Witch of the West/Elphaba from The Wizard of Oz, while Lilia channels Glinda.

As first heard in that D23 activation, the Witches’ Road comes with its own jingle: “Down, down, down the Road, down the Witches’ Road.”

Agatha All Along will kick off with two episodes Sep. 18. Watch the trailer above.
