Agatha All Along Trailer: Kathryn Hahn and Aubrey Plaza Lead the MCU’s Coven

Kathryn Hahn's Agatha Harkness was a highlight of WandaVision , and she's going to become a prominent player in the MCU with her own show. The show, which has undergone several title changes like Agatha: Darkhold Diaries and even one with a C.S Lewis twist , will now be called Agatha All Along.

Marvel Studios has released the first trailer for the show, which picks up with a brainwashed Agatha still stuck in Westview. Starting as a crime thriller where Hahn plays Agatha as a detective, the trailer quickly changes tone with the introduction of Aubrey Plaza's mysterious character.

Watch the Agatha All Along trailer below.

Eagle-eyed viewers will spot a grown-up Billy (played by Joe Locke) from WandaVision , though why Wanda's imaginary kid is working with Agatha is anyone's guess. Like the show it spun off from, Agatha looks like it will blend horror and comedy, dialing up both ends of the spectrum.

As for the story, it looks like Agatha will be assembling a new coven with some reluctant members in hopes of reawakening her powers. While the trailer does not show her, we wouldn't be surprised to see Elizabeth Olsen return as the Scarlet Witch for a cameo.

Agatha isn't the only character getting a spinoff from WandaVision , as Marvel Television is also developing a Vision series for Disney Plus, releasing in 2026 .

Here is the official description of the series.

In Agatha All Along, the infamous Agatha Harkness finds herself down and out of power after a suspicious goth Teen helps break her free from a distorted spell. Her interest is piqued when he begs her to take him on the legendary Witches’ Road, a magical gauntlet of trials that, if survived, rewards a witch with what they’re missing. Together, Agatha and this mysterious Teen pull together a desperate coven, and set off down, down, down The Road…
