Why Crime Drama 'Nocturne' Swapped Swedish Cold for Western Pennsylvania

The streaming adaptation of Lars Kepler's crime novel The Sandman pairs Liev Schreiber and Stephen Graham in a localized psychological chase that leans directly into regional speech patterns. 

Apple TV launched its new psychological crime drama "Nocturne" on Friday, October 30, shifting a celebrated Swedish serial killer saga from Nordic pine forests into the rugged hills and river valleys of Western Pennsylvania. The series, debuting with two episodes before releasing weekly through December 25, reimagines Lars Kepler's bestselling 2012 novel "The Sandman" for an American rust-belt setting.

Liev Schreiber stars as Jonah Lynn, a grieving former Philadelphia police detective who retired to his late wife's hometown of Fairhaven, Pennsylvania. Three years after Lynn helped local police chief Dave Ellison, played by Bill Camp, capture notorious murderer Jurek Walter, one of Walter's child kidnapping victims walks out of the woods alive. The discovery reopens the case and prompts Lynn's goddaughter, FBI agent Saga Bauer, played by Zazie Beetz, to enter Riverside Psychiatric Hospital undercover to learn whether the survivor's missing sister remains alive.

Created by Rowan Joffé and developed by co-showrunner John Hlavin, a Cleveland native, the production originally considered filming across Maine to replicate the lakes and rural isolation of the original Scandinavian book. The team dropped that plan after concluding Western Pennsylvania offered an uncanny geographical and cultural match for Nordic noir.

Hlavin pointed to the Commonwealth's natural landscape and insular rural enclaves as primary drivers for the relocation. "Swedish noir and Scandi noir maps most directly to Western Pennsylvania because of the 16 million acres of woods in the state, because of the way the sun travels through the canopy of trees, because of the ruralness of so much of the state, because of the private nature of a lot of its residents and people that keep to themselves," Hlavin said. "We fictionalize what's underneath that."

Rather than flattening regional speech into generic broadcast English, the production actively embraced southwestern Pennsylvania dialect. The decision followed Schreiber's choice of a modified Philadelphia accent for his detective, prompting filmmakers to establish localized vocal textures across the ensemble. The production hired dialect coach Susanne Selby and distributed phonetic guides to the cast.

British actor Stephen Graham, who plays the imprisoned killer Walter, absorbed the local rhythm directly from the film crew and transportation team. Graham latched onto distinct regional pronunciations, including hearing the name of hospital nurse Karl, played by Rory Culkin, pronounced like "coral," as well as local shorthand like "Stillers."

"The crew were great. My driver was fantastic, particularly, and all the Teamsters were great, so I just nicked their accents," Graham said. "I really liked the place where we filmed. I got to walk around a lot, and I got to experience the woods and also the culture, so it had a major effect on my character."

Beetz calibrated her accent differently to reflect an ambitious investigator eager to build an outside career. "My character had an energy of 'I want to leave and do something else,'" Beetz said. "We decided on tamping it down a little bit and doing a very, very light take on the Pittsburgh accent. Also, we were thinking, she's doing agent work undercover, she would potentially try to have lost the accent to neutralize her tone."

Filming took place throughout 2025 across Allegheny, Armstrong, Beaver, Butler, and Westmoreland counties. The crew turned everyday regional institutions into thriller backdrops. Digitally enhanced Brutalist buildings at the Community College of Allegheny County South Campus provided the exterior facade for Riverside Psychiatric Hospital. The institution's underground high-security housing ward was constructed inside the former Cinelease Studios in Warrendale, while upper administrative corridors filmed at Tech One in Monroeville.

The fictional community of Fairhaven was stitched together from streetscapes in Beaver, Butler, Vandergrift, Fombell, and Dormont, while the Butler County Court Center substituted for the Allegheny County Courthouse. Dense woodlands around Portersville, Freeport, Harmony, Sarver, and Cabot supplied the eerie, sun-dappled foliage where Walter hid his victims.

The lead actors immersed themselves in local neighborhoods. Schreiber lived in Sewickley with his family, noting the region's strong cultural undercurrent reminded him of Brooklyn's artistic communities decades ago. Beetz stayed in Pittsburgh's Bloomfield neighborhood, frequenting local culinary fixtures including Apteka, Fet-Fisk, and The Butterwood for late-night bakery stops.
