Who plays Agatha Harkness?

The inimitable Kathryn Hahn is Agatha Harkness in the MCU. She was so beloved in WandaVision that she got her own spinoff. In an interview with Deadline, Hahn raved about her experience with playing character. "I love her so much. I mean, she's a witch, so what could be more delicious?"

Who is in the Agatha All Along cast?

The Agatha All Along cast includes: 

Kathryn Hahn as Agatha Harkness

Kathryn Hahn is returning as Agatha Harkness. She famously sang the "Agatha All Along" song from WandaVision.

During an interview with TV Line, Hahn teased the possibility of more singing. "Who knows, there may be a little song here or there … but no one is saying anything about that—certainly not me!”

In WandaVision, Agatha Harkness' identity wasn't revealed until Episode 7.

Up to that point, she was merely a meddling neighbor named Agnes. Then her scheme to access the Darkhold and Wanda's chaos magic was unveiled.

WandaVision was considered the kickoff of a Kathryn Hahn renaissance, making her a household name—finally, after so many years of stealing scenes in movies like Stepbrothers and Bad Moms and TV shows like the criminally underrated Mrs. Fletcher and Parks and Recreation. It's about time she got her flowers!

Also, we'd be remiss not to mention the incredible meme her character inspired. Yes, the infamous wink is from Agatha Harkness.

Debra Jo Rupp as Mrs. Hart/Sharon Davis

Debra Jo Rupp, most famous for starring as Kitty in That '70s Show and That '90s Show, will reprise her role as Mrs. Hart, who she played in WandaVision.

At the end of the series, it was revealed that her name wasn't actually Mrs. Hart, but Sharon Davis.

Emma Caulfield Ford as Dottie/Sarah Proctor

Buffy the Vampire Slayer star Emma Caulfield Ford returns as Dottie, one of the Westview neighbors caught up in the Scarlet Witch's scheme.

In October 2022, she revealed to Vanity Fair that she was diagnosed with MS and that filming WandaVision in hot summer weather exacerbated some of her symptoms. Caulfield Ford explained that she didn't say anything to the rest of the cast, crew or showrunners at the time, but that they all know now, including showrunner Jac Schaefer, and that she likely won't have to work in extreme heat anymore—and that if it ever comes up that she does, everyone knows that extra precautions should be taken.

"I am going back to work! Everyone has been notified that needs to be notified. I can’t put myself through what I did with WandaVision again. I can’t do that. They did nothing wrong," she said. "They had no idea what was going on with me. They didn’t ask anything of me that was like, 'I need to call my agent!' They’re asking me to just sit and chat and do my dialogue. It’s not hard."

Patti LuPone as Lilia Calderu

Broadway legend Patti LuPone, whose presence in the cast has led some to speculate that the show may indeed have a musical element to it, confirmed on The View that she would be playing Lilia Calderu, a member of Agatha's coven. 

She described the character, who made her Marvel comics debut in 1973, as "a 450-year-old Sicilian witch whose power is divination and whose trial is tarot."
