A new trailer for the highly anticipated Disney+ miniseries 'Agatha All Along' was unveiled at the D23 Expo, providing Marvel fans with an exciting glimpse into the series.

The show centers on Agatha Harkness, played by Kathryn Hahn, who was first introduced in 'WandaVision' as a seemingly innocuous neighbor named Agnes before revealing her true identity as a powerful witch.

Set after the events of 'WandaVision', 'Agatha All Along' explores Agatha's quest to reclaim her lost powers, with Hahn reprising her role and Jen Schaefer serving as the series creator and head writer.

The series' logline describes 'The Witches' Road' as a magical gauntlet of trials that rewards witches with what they seek if they survive, hinting at the challenges Agatha and her coven will face.

The trailer suggests that Agatha's pursuit of power comes at a high cost, indicating that her coven may bear the burden of her ambitions.

In the trailer, Agatha is depicted in a forest as a detective, with references to Wanda Maximoff, hinting at connections to the larger Marvel Cinematic Universe.

Joining Hahn in the series are co-stars Joe Locke, Patti LuPone, Sasheer Zamata, Ali Ahn, Debra Jo Rupp, and Aubrey Plaza, who adds to the show's eerie atmosphere.

During the D23 event, Hahn and her cast performed an original song titled 'The Ballad of the Witches Road', written by the acclaimed duo Kristen Anderson-Lopez and Robert Lopez.

The series is set to premiere with its first two episodes on September 18, 2024, making it one of the few Marvel projects scheduled for release that year.

The timing of the series' reveal aligns with the Halloween season, creating heightened anticipation among fans eager to explore Agatha's chaotic world.

Originally announced as 'Agatha: House of Harkness', the series has undergone several name changes, ultimately settling on 'Agatha All Along' as revealed in May 2024.
