When Aubrey Plaza was first announced as a dark witch in Agatha All Along, I thought, “That makes sense.” It was the same feeling for the actress who has dabbled in the dark arts, telling WSJ Magazine, “What’s better than playing in the witch-witchy worlds of witches?”

As she reprises her role as the witch everyone loves to hate, Kathryn Hahn says it “makes total sense” she's continuing the story. The “Agatha All Along” star, who first introduced Agatha Harkness to the world in the hit 2021 Marvel series “WandaVision,” said the rich complexity of her character excites her.

The Marvel Cinematic Universe built an empire on minor characters, proving that strong execution and an overarching brand could elevate once-fringe figures like Black Widow or the Guardians of the Galaxy into franchise mainstays.
