“Without spoiling too much, I will say that my character is very powerful and mysterious and has almost, like, a shape-shifting quality where you kind of never know what version you’re gonna get,” — Aubrey Plaza, speaking about her “Agatha All Along” role.

Aubrey Plaza speaks in a generic publicity interview for “Agatha All Along” on Disney+. The nine-episode, live-action series follows the return of the MCU’s Agatha Harkness following the events of 2021’s “WandaVision.” Here, Harkness finds herself free of Wanda’s spell thanks to the help of a “suspicious goth teen” (played by Joe Locke). Unfortunately, she’s also powerless. The teen asks Harkness to seek out the legendary Witches’ Road, a gauntlet of trials that will reward them with “what they’re missing” if they survive. Together with a “desperate coven,” they embark on this road, which will see them cross paths with Plaza’s equally mysterious character.

The first two episodes of “Agatha All Along” premiere September 18 on Disney+. Episodes will roll out weekly until October 30, when the final two episodes will launch.
