Pawnee, Indiana? Nope, that’s the Agatha All Along premiere red carpet!

Adam Scott and Amy Poehler turned the premiere of Marvel’s latest series into an unofficial Parks and Recreation reunion on Monday, Sept. 16, when they arrived to support two of their fellow alumni, Aubrey Plaza and Kathryn Hahn.

The group of four posed for photos together on the purple carpet after Scott, 44, seemingly surprised the rest of his former costars.

A video shared by Marvel Studios shows the actor, who played Ben Wyatt in the NBC sitcom, sneaking up on Poehler, 53, Plaza, 40, and Hahn, 51.

The Agatha All Along stars appeared shocked as Scott emerged from behind the carpet and joined them for the photo opp, with Plaza swearing as Hahn tells the actor to “slide on in.”

Elsewhere at the premiere, Poehler, who played Parks and Rec’s main protagonist Leslie Knope, extended a big hun to Hahn, who joined the show as Jennifer Barkley in its later seasons, footage shared by The Hollywood Reporter shows.

Also in the clips, the duo snapped a selfie with Plaza, who played April Ludgate in the sitcom.

On the carpet, Hahn expressed her excitement at working alongside Plaza in Agatha All Along because their Parks and Rec screentime never overlapped.

“That was a dream,” she told The Hollywood Reporter. “We had never had any scenes together in Parks and Rec. I think we passed each other in hallways, but for this to be the first time we really worked together was incredible.”

Plus, Hahn praised Plaza’s abilities, telling the outlet that she is “such an extraordinary actor.”

“So, to be able to play with her like this was so fun,” she added.

Hahn also discussed her and Plaza’s long-awaited collaboration in an interview with Entertainment Weekly.

“I just admire her so much as a performer, and I was so excited that she was playing this part,” she told the outlet. “Weirdly, once we got together to start shooting, our conversations stopped. We gave each other a lot of space. It's not like we ignored each other. We talked, but we never talked about [performance]."

"So when we got on stage together, there was definitely a feeling of on your heels, I don't know what's going to come at me, which was really exciting," she added.

Picking up right where WandaVision left off, Agatha All Along will see Agatha (Hahn) "down and out of power after the suspicious goth teen helps break her free from a distorted spell," per an official synopsis.

Along with Hahn and Plaza, the Marvel series also stars Patti LuPone, Joe Locke, Sasheer Zamata, Ali Ahn, Debra Jo Rupp and Miles Gutierrez-Riley.
