If you are already nostalgic for WandaVision, you are not alone. Kathryn Hahn is also.

As any fan knows, it was “Agatha All Along,” with Hahn’s favorite villain turning out to be one of the most delicious and devious additions to the Marvel Cinematic Universe. And as much as we were all excited to see the 47-year-old star causing trouble for Wanda (Elizabeth Olsen) and still singing her catchy theme song, nobody loved Agatha Harkness more than Hahn himself.

“I’m nostalgic for it because it was so much fun, hard work,” Hahn told E! News in a phone interview just a week after the WandaVision finale. “Of course it was one of the hardest things I’ve ever done, but it was also one of the most meaningful.”

Already known for her comedic twists and turns in Step Brothers, Bad Moms, and Parks and Recreation, as well as her critically acclaimed appearances in more dramatic fare like Mrs. Fletcher and I Know This Much Is True, Hahn found her breakout role in The Witch Centuries , which made headlines and discussed a Hahn renaissance almost 20 years after her film debut in How to Lose a Guy in 10 Days in 2003.
