Agatha All Along trailer embraces witchy horrors with powerless Kathryn Hahn

Marvel's witch is back, and there's hell to pay.

Kathryn Hahn's Agatha Harkness returns to not quite her former glory in the first Agatha All Along trailer, providing the first look and new plot details on the WandaVision spinoff series coming to Disney+.

Heartstopper breakout Joe Locke plays a suspicious goth teen who helps snap Agatha out of the spell Elizabeth Olsen's Wanda Maximoff used to trap her back during the events of WandaVision. Only now the power-absorbing witch can't access her magic.

"I miss the glory days," Agatha says in the footage. "She took every bit of power I had, but I can be that witch again."

But she has a plan.

Agatha is determined to travel down the legendary Witches’ Road, a magical gauntlet of trials that rewards a witch with what they’re missing, assuming she survives it. With this goth teen, she assembles a coven of desperate witches to face the Road together.

Similar to Doctor Strange in the Multiverse of Madness, which was the last time we saw Olsen's Wanda and chaos magic, Agatha All Along is clearly embracing the horror elements of the Marvel Cinematic Universe, with fearsome apparitions, demons, and entities galore.

From showrunner Jac Schaeffer, who directs the pilot episode, Agatha All Along also features Sasheer Zamata, Ali Ahn, Maria Dizzia, Paul Adelstein, Miles Gutierrez-Riley, Okwui Okpokwasili, Debra Jo Rupp, Patti LuPone, and Aubrey Plaza.

LuPone previously spilled the beans that she's playing Sicilian witch Lilia Calderu, while rumors abound about Locke possibly playing Billy Kaplan, a reincarnation of Wanda's magicked-into-existence son who becomes comic book hero of the Young Avengers team Wiccan. Though that hasn't been officially confirmed.

The series premieres two episodes on Disney+ this Sept. 18 at 9 p.m. ET/6 p.m. PT. Watch the trailer above.
