Dick Wolf's hit NBC drama Chicago P.D. centers on District 21's Intelligence Unit as they confront organized crime, drug trafficking, and high-profile murders. Showrunner Gwen Sigan, stars Jason Beghe and Marina Squerciati, and technical advisors work behind the scenes to balance police procedural realism with intense character drama across every episode.
If you're looking for how Chicago P.D. captures the grit of the Windy City, the truth comes down to location shoots, tactical preparation, and technical advisory teams. The production films on location throughout Chicago neighborhoods rather than relying solely on backlot sets in Los Angeles. This hands-on approach directly influences character arcs, tactical movements, and overall narrative authenticity.
How Chicago P.D. Builds Realism On and Off Screen
Authenticity drives the core appeal of Chicago P.D.. Unlike standard police procedurals filmed entirely on soundstages, the series grounds its action in real Midwestern settings and actual police protocols.
Real-Life Technical Advisors and Tactical Training
Every episode relies on guidance from retired law enforcement personnel and active tactical consultants. Before cameras roll, cast members undergo specialized instruction to ensure their physical movements match real-life officers:
- Weapon handling and clearing: Actors practice room-clearing drills, firearm safety, and weapon transitions under expert supervision.
- Vehicle extractions and pursuits: Stunt coordinators and police advisors design driving sequences to reflect actual department pursuit guidelines.
- Radio codes and terminology: Scriptwriters incorporate precise Chicago Police Department (CPD) terminology, call signs, and dispatch signals into dialogue.
Jason Beghe, who portrays Sergeant Hank Voight, spent time shadowing veteran investigators to understand the psychological weight and vocal cadence of senior officers. This groundwork shapes Voight's commanding, gravelly screen presence.
On-Location Filming Across Chicago
The city itself functions as a primary character. Production works out of Cinespace Chicago Film Studios, using soundstages for interior precinct spaces while shooting exterior scenes in diverse neighborhoods:
- Pilsen and Little Village: Frequently featured during tactical street operations and community-focused storylines.
- Englewood and Austin: Used for high-stakes precinct investigations and atmospheric exterior shots.
- The Loop and Near North Side: Provide backdrops for corporate crime, political storylines, and central courthouse scenes.
Filming outdoors in authentic Chicago weather—from sub-zero winter blasts to humid summer nights—adds palpable tension that studio lighting cannot replicate.

Hank Voight: The Morally Complex Anchor
Sergeant Hank Voight remains one of television's most complex leads. Operating in shades of gray, Voight frequently crosses ethical lines to protect victims and bring criminals to justice. His background in the old-school police force creates constant friction with modern oversight committees and internal affairs investigators.
Evolving Unit Relationships
Over 11+ seasons, the unit dynamic has shifted through departures and new arrivals:
- Kevin Atwater (LaRoyce Hawkins): Provides a vital perspective on community relations, racial dynamics, and the heavy personal toll of wearing the badge in modern Chicago.
- Kim Burgess (Marina Squerciati) and Adam Ruzek (Patrick John Flueger): Represent the emotional heart of the team. Their shared trauma, personal relationship, and professional partnership ground the show's higher-stakes storylines.
- Dante Torres (Benjamin Levy Aguilar): Brings fresh energy as a recruited officer whose past connections to street life challenge standard procedural methods.
The Production Process: From Script to Screen
Creating an episode of Chicago P.D. requires a tight eight-to-nine-day shooting schedule per episode. Writing rooms led by showrunners analyze real-world headlines to craft compelling fictional cases.
Step 1: Concept and Script Development
Writers draft storylines months in advance, consulting technical advisors to ensure law enforcement procedures fit narrative beats without breaking suspension of disbelief.
Step 2: Table Reads and Tactical Rehearsals
The cast meets for script walkthroughs, followed by physical blocking rehearsals with stunt coordinators for shootouts or foot chases.
Step 3: Principal Photography
Scenes split between indoor soundstages at Cinespace Studios and multi-day location shoots. Director teams coordinate with local city authorities to lock down streets and safely detonate cinematic pyrotechnics.
Step 4: Post-Production Sound and Editing
Editors weave together fast-paced action cuts, adding moody atmospheric scores and authentic police radio chatter to heighten suspense.
Crossover Universe: The One Chicago Franchise
Chicago P.D. does not exist in a vacuum. It forms a crucial pillar of producer Dick Wolf's interconnected "One Chicago" universe alongside Chicago Fire and Chicago Med.
- Shared Characters: Paramedics from Chicago Fire regularly treat injured officers, while doctors from Chicago Med handle trauma cases stemming from Intelligence Unit busts.
- Multi-Part Crossover Events: Annual television events link storylines across all three series, creating movie-length narratives that dominate network ratings.
- Unified Continuity: Events occurring in one show carry permanent consequences into the others, deepening character histories over years of broadcasting.
Common Production Challenges and How the Crew Solves Them
Filming a gritty procedural in a major metropolitan city presents distinct operational hurdles:
- Weather Extremes: Sub-zero Chicago winters freeze camera equipment and strain crew members. Production uses heated tenting, specialized gear lubricants, and insulated wardrobes to maintain shooting schedules.
- Public Safety and Crowd Control: Outdoor shootouts require extensive coordination with local authorities, public notifications, and off-duty police detail to secure perimeters.
- Authentic Props: Badges, uniforms, and marked vehicles must strictly comply with legal guidelines so prop equipment is never confused with active duty law enforcement tools outside set boundaries.
