Chicago Fire was never pitched to NBC with the idea of launching a franchise of shows
Dick Wolf is a household name for a reason. If you turn on a TV at any given hour, you will likely stumble across a gritty procedural with his signature stamp on it. But while the Law & Order machine felt like an inevitable march toward network dominance, his second massive empire started with a surprisingly blank slate.
When creators Derek Haas and Michael Brandt first sat down to pitch Chicago Fire to NBC, they weren’t holding the blueprints for a multi-show universe. They didn’t have a Chicago P.D. crossover lined up, nor were they planning the medical emergencies of Chicago Med. They just wanted to write a damn good show about firefighters.
Let’s pull back the curtain on how a single, focused drama about Firehouse 51 accidentally triggered one of the most lucrative and expansive franchises in modern television history.
The Original Spark: Just a Story About Firehouse 51
In the early 2010s, NBC was in a bit of a programming rut. They needed a hit, something with raw, human energy. Enter Derek Haas and Michael Brandt. The duo wasn’t thinking about a “One Chicago” sandbox. They were completely consumed by the logistical and emotional reality of a single firehouse in the Windy City.
An Unfiltered Look at Everyday Heroes
The pitch was simple: follow the men and women of Firehouse 51. The writers wanted to capture the unique pressure cooker of firefighting—the literal heat of the blaze contrasted with the slow-burn trauma that follows these heroes home. It was designed to be an ensemble drama, rooted heavily in character dynamics rather than a corporate strategy to rule the Tuesday, Wednesday, and Thursday night time slots.
The Shadow of Law & Order
Because Dick Wolf was attached as an executive producer, outsiders naturally assumed a master plan was in play. After all, Wolf is the undisputed king of the spin-off. But the creative team pushed back against this narrative early on. They wanted Chicago Fire to stand on its own two feet before anyone even uttered the word “franchise.” The focus was entirely on making the pilot episode as gripping as humanly possible.
Why a Franchise Wasn’t on the Radar
To understand why a franchise wasn’t originally intended, you have to look at the landscape of network television in 2012. The industry was shifting. Streaming was starting to flex its muscles, and launching one successful network drama was already a statistical miracle. Trying to pitch a three-show universe right out of the gate would have looked less like ambition and more like hubris.
The Extreme Risk of Network Television Pitches
When you pitch a show to a major network like NBC, you are fighting for survival. Networks reject hundreds of scripts a year. If Haas and Brandt had walked into the executive suite and said, “We want to give you a show, and then three years from now we’re going to launch a police spin-off, and then a medical drama,” they likely would have been laughed out of the room. You don’t buy the curtains before you build the house.
Dick Wolf’s Philosophy: Build the Foundation First
Even Dick Wolf, with all his industry clout, knew better than to force a universe. His philosophy has always been to build a rock-solid foundation first. A spin-off only works if the mothership is robust enough to fuel it. The priority was establishing Matthew Casey and Kelly Severide as compelling leads, ensuring the special effects looked cinematic, and proving that audiences cared enough to tune in week after week.
The Turning Point: Enter Officer Voight
So, how did we get from a self-contained firefighting drama to an all-consuming television empire? It all started with a villain.
The Introduction of a Compelling Antagonist
In the first season of Chicago Fire, the writers introduced a dirty cop named Hank Voight, played with terrifying charisma by Jason Beghe. Voight was initially brought in to serve as a roadblock for Casey, threatening him and pushing the fire department to its limits. He wasn’t designed to be a hero; he was a plot device meant to generate friction.
How Jason Beghe Changed the Creative Trajectory
Something unexpected happened when the cameras started rolling: Beghe stole every single scene he was in. He brought a layered, magnetic complexity to a character who easily could have been a cartoon villain. The executives at NBC looked at the dailies and realized they had lightning in a bottle. Instead of wrapping up Voight’s storyline and sending him away, they started asking a fascinating question: What does his world look like?
The Backdoor Pilot That Started It All
This creative spark led to a “backdoor pilot” embedded directly within Chicago Fire. Rather than launching a brand-new show from scratch, NBC used the established audience of Firehouse 51 to introduce the Intelligence Unit of the Chicago Police Department. By the time Chicago P.D. officially premiered in 2014, the audience was already hooked on the crossover potential.
The Anatomy of a Modern TV Universe
Once Chicago P.D. proved to be a ratings juggernaut, the floodgates opened. The accidental franchise suddenly became a deliberate corporate strategy, leading to the birth of Chicago Med in 2015 and the short-lived Chicago Justice in 2017.
The Shared Geography of the Windy City
What makes the One Chicago universe work so beautifully—and why it captured the public imagination—is its geographic and narrative density. The shows don’t just share a city name; they share an ecosystem.
Molly’s Bar as the Ultimate Narrative Anchor
Think of Molly’s Bar as the water cooler of the entire franchise. It is a brilliant narrative anchor. Firefighters, cops, and doctors all walk into the same pub at the end of a brutal shift to grab a beer and complain about their bosses. This simple, recurring set allowed characters from different shows to cross paths organically, without the need for a massive, heavily promoted crossover event.
The Power of the Casual Crossover
Before Chicago Fire, crossovers were treated like major television events—hyped for weeks and saved for sweeps month. The One Chicago team changed the game by normalizing the “casual crossover.” A paramedic from Fire drops a patient off at Med, exchanges two lines of dialogue with a doctor, and walks out. This seamless integration makes the world feel incredibly alive and authentic.
The Unintended Playbook for Modern Networks
The accidental success of Chicago Fire completely rewrote the playbook for network television executives. Suddenly, every network wanted its own interconnected universe. We saw this strategy replicated with the 9-1-1 franchise on Fox/ABC and the expanding FBI universe on CBS.
The Economics of Interconnected Storytelling
Why are networks so obsessed with this model? Because it is an economic goldmine. If you can convince a viewer to watch Chicago Fire at 8 PM, they are vastly more likely to stay tuned for Chicago P.D. at 9 PM and Chicago Med at 10 PM. It builds an incredibly loyal block of viewers, turning a single night of television into an impenetrable ratings fortress.
Capturing Lightning in a Bottle Twice
The irony is that many of the networks trying to replicate this success are doing it backward. They are pitching franchises from day one, trying to force chemistry and connectivity that hasn’t been earned. The magic of Chicago Fire is that its universe grew organically out of good writing and exceptional character work, not a corporate boardroom mandate.
Conclusion
At the end of the day, Chicago Fire teaches us a valuable lesson about storytelling: focus on the spark before you try to ignite a wildfire. Derek Haas, Michael Brandt, and Dick Wolf didn’t set out to conquer network television with an army of interconnected dramas in 2012. They set out to tell an authentic, high-stakes story about the human beings who run into burning buildings when everyone else is running out.
By prioritizing character over corporate strategy, they stumbled into a billion-dollar empire. It just goes to show that sometimes, the best master plans are the ones you never actually make.
