A true crime doc shoots in Doylestown this week. Where are they filming?

A documentary series is filming in Doylestown on Tuesday and Wednesday, according to executive producer Steph Burns.

The four-part series, which streams next month, is shooting Tuesday at Chambers 19 Bistro & Bar on Main Street. About 25 locals are extras on the shoot, Burns said.

The true crime documentary, "The Godfather of Fentanyl,, which premieres on an unspecified streamer in August, tells the story of George Marquardt, a self-taught chemist and illict drug maker whom the DEA has said was the only source of illegal fentanyl in the U.S. before his arrest in 1993.

His product was tied to at least 126 overdoses, mostly on the East Coast.

The shoot at Chambers Bistro reenacts a pivotal moment of the investigation into the source of the illegal fentanyl. The Main Street bar is standing in for an Irish pub in Boston, where a dealer divulged a small detail to an undercover DEA agent that led to Marquardt's arrest in Kansas.

Doylestown extras get moment of fame

Though there's no local connection in the "Godfather of Fentanyl" story, the shoot at Chambers was a neighborhood affair. A handful of the extras live on Burns' street in Doylestown, they said.

"It's nice getting to see what your neighbors do," said Wendy Stone, who wore ripped-knee jeans for the scene, which is set in 1993. Stone also helped make jackets that DEA agents wear in the doc, she said.

Nancy Dickson, who wore a checked pink-and-beige jacket with padded shoulders, joked that it it looked like her work jackets from the 80s.

"I wasn't alive in the 90s, so I like [the outfits]," said Katie Spillane. The extras were each given a free drink of their choice for the bar scene.

Some of the extras dressed themselves: Elaine Pasqua, another neighbor of Burns, wore vintage overalls she'd saved for years.

The documentary is produced by Steven Rotfeld Productions in Bryn Mawr, which has previously produced sports, pop science, and historical non-fiction programming.

The series will also film on Wednesday, at a New Britain funeral home.
