Marvel series Agatha All Along: Everything you need to know from plot, cast, release date

Marvel enthusiasts, brace yourselves!

The first trailer for the hotly anticipated Marvel series Agatha All Along has finally landed after a series of setbacks and rebrandings. Starring the inimitable Kathryn Hahn, this Disney+ series picks up where the critically lauded WandaVision left off in 2021.

Agatha All Along is set to debut with a double-episode premiere, following the formidable Agatha Harkness as she battles to escape the clutches of Wanda Maximoff's enchantment and reclaim her formidable powers. The freshly released trailer teases what's in store for fans, igniting excitement for the return of the beloved character and the potential havoc she may wreak in her quest for vengeance.

The unveiling of the trailer comes on the heels of a tumultuous production period for the new MCU installment, which has been marred by repeated delays, different series titles, and speculation about its direction and the broader trajectory of the MCU.

Here's the lowdown on everything we've gleaned about Agatha All Along - be warned, spoilers for WandaVision lie ahead.

What is Agatha All Along about?

Set in the aftermath of Wandavision, the series resumes the tale of Agatha Harkness, who found herself ensnared by Wanda Maximoff/Scarlett Witch's spell in the climactic finale. The initial trailer for Agatha All Along, which debuted on July 8, delves into life under the new enchantment, with Agatha taking on the role of a sleuth delving into a mysterious demise.

As she scrutinizes the corpse, the toe tag mystically discloses a name that rings a bell: "W. Maximoff". Enter Witch Rio Vidal, portrayed by Audrey Plaza, who implores Agatha to "claw your way out" from under Wanda's bewitching influence.

The trailer reveals Agatha mourning her lost powers, yet she confidently asserts "I can be that witch again".

Marvel's official plot synopsis for the show reads: "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…"

Who are the cast members?

Kathryn Hahn leads the cast, with Aubrey Plaza making her first appearance in the MCU as Rio Vidal, a warrior witch in Harkness and Calderu's coven. The ensemble also includes Heartstopper's Joe Locke, SNL's Sasheer Zamata, Orange is the New Black's Ali Ahn, Maria Dizzia, Paul Adelstein, Miles Gutierrez-Riley, Okwui Okpokwasili, Debra Jo Rupp and Patti LuPone.

Jac Schaeffer, who penned WandaVision, serves as the head writer and executive producer.

When will Agatha All Along be released?

The new series will premiere on Disney+ on Wednesday, September 18 with two episodes. The remaining seven episodes will be released weekly until November 6.

Why has the series' title undergone so many changes?

Since its announcement in 2021, the series has seen a number of title changes. Initially named Agatha: House of Harkness, it was rebranded as Agatha: Coven of Chaos in July 2022.

In September 2023, the title was altered once more to Agatha: Darkhold Diaries. With the reveal of the premiere date earlier this year, the final title was confirmed as Agatha All Along, a nod to the catchy tune from WandaVision that took the internet by storm.

Marvel enthusiasts have speculated that the constant title changes indicate Marvel's uncertainty regarding their TV shows. However, Variety suggested that the shifting titles are more indicative of Agatha "is up to her old skulduggery."

Disney also shared a video suggesting that the title changes were "orchestrated by (Harkness) as a way of messing with Marvel fans."
