Marvel's 'Agatha All Along' is coming: Release date, cast, how to watch

Agatha Harkness is back in her own spinoff, "Agatha All Along," which takes place after the acclaimed Marvel show "WandaVision."

The witch is building a new coven after she faced the Scarlet Witch in "WandaVision" and is now struggling to remove a spell.

Kathryn Hahn will take on the role of Agatha Harkness once again.

Elizabeth Olsen, who starred in "WandaVision" as Wanda Maximoff, or the Scarlet Witch, is not on the cast list for "Agatha All Along." Olsen has played the character since she first appeared in the post-credit scene of the Marvel movie "Captain America: The Winter Soldier" in 2014. She reprised the role in "Doctor Strange in the Multiverse of Madness," which takes place after "WandaVision."

Here's how to watch the latest wicked addition to the Marvel Universe, including the premiere date and how many episodes are coming out each week.

What is the premise of 'Agatha All Along'?

"Agatha All Along" takes place when a teenager frees Agatha from a "distorted spell" and asks her to take him down the Witches' Road, "a magical gauntlet of trials that, if survived, rewards a witch with what they're missing," according to Disney+'s website.

The series follows Agatha as she puts together a coven and attempts to regain her power.

The previews of the show drop hints that the audience is meeting up with Agatha after Wanda takes her powers from her.

"That witch is gone," Rio Vidal, played by Aubrey Plaza, is seen telling Agatha in a preview released two months ago. "Leaving you trapped in her distorted spell."

What happened in 'WandaVision'?

If you want to watch "WandaVision," and are trying to avoid spoilers ahead of the premiere of Agatha All Along, stop reading here.

"WandaVision," which premiered in 2021, followed superhero Wanda Maximoff, played by Elizabeth Olsen, and her robot husband, Vision, played by Paul Bettany, following the events of the Marvel movie "Avengers: End Game."

Wanda uses her powers, or magic, to revive her deceased husband, Vision, who dies in "Avengers: Infinity War" after she returns from The Blip.

She retrieves and casts a spell that wipes the memory of the entire town of Westview. The power calls to Agatha Harkness, a centuries-old witch, who, in episode 7, revealed she schemed her way into winning Wanda's trust.

"Agatha All Along" is the song that plays during the montage that plays after Agatha reveals her true identity.

Agatha helps Wanda discover the origins of her powers and then tries to steal them for herself.

An epic battle ensues, and the Scarlet Witch then takes all of Agatha's powers and traps her in Westview, wiping her memory of who she was and turning her into the role she chose: "the nosy neighbor."
