Mark Harmon‘s Shocking Departure from NCIS After 20 Iconic Seasons Leaves Uncertain Future for Show‘s Success
After 20 incredible seasons bringing the character of Leroy Jethro Gibbs to life and steering the show to the top of the Nielsen ratings, Mark Harmon has decided to leave his starring role on CBS‘s hit show NCIS. For two decades, Harmon anchored the series‘ cast and storylines as the steadfast, no-nonsense leader of the Naval Criminal Investigative Service team. His shocking exit episode "Great Wide Open" left fans reeling and questioning what the future holds for NCIS.
While initially cryptic regarding his reasons for departing, Harmon later shared that after so many years inhabiting the role of Gibbs, he felt it was simply time to move on and face new creative challenges. This difficult decision closes one chapter for Harmon while opening up new possibilities. But for the legions of devoted "NCIS" fans, it also sparks worries that the show cannot maintain success without the actor that has long been its anchor.
By the Numbers: Quantifying a Hit Show‘s Uncertain Future
Just how staggering are the shoes CBS now looks to fill with Harmon‘s exit? Since joining the network‘s lineup in 2003, NCIS has aired over 450 episodes across 19 seasons as of his departure. It ranks as the most watched drama on television for 11 consecutive seasons with over 20 million average viewers tuning in during its peak.
To capture that scale, if you took every resident of New York City and Chicago combined, that sum still falls 5 million short of the average NCIS viewership just a few short years ago. In an era where many competing hit shows fade quickly from prominence, NCIS had unmatched staying power thanks in large part to Mark Harmon‘s consistency at the helm.
NCIS’s rise has also demanded attention from awards circuits, competing for Emmys in both acting and writing categories. WhileHarmon himself proved too elusive to earn a trophy, his peers recognized the caliber of performance he delivered by nominating him for Outstanding Lead Actor a remarkable 10 times.
In many ways, Quantifying the success Harmon fueled for 20 seasons only enhances the monumental challenge CBS now faces continuing NCIS’s legacy without its long-time leader steering the ship.
Recreating the NCIS Persona Anchored By Mark Harmon as Gibbs
When reminiscing on favorite moments from Harmon’s NCIS tenure, many quickly harken back to the steely resolve and relentless determination he poured into Agent Gibbs right from episode one. Whether facing dangerous criminals, corrupt bureaucrats, or even terrorist networks, Gibbs stared them down and gave pursuit without hesitation or an ounce of intimidation clouding his icy glare.
Though partial to military precision and comfortable issuing orders inside NCIS headquarters, Gibbs also carved out a niche as defender of the defenseless. His marine training ingrained rock-solid principles of honor and loyalty that turned Gibbs into a crusader for justice far beyond just crime-solving.
Harmon‘s gravitas in those difficult moments confronting harsh realities head-on set a tone that empowered allies and friends while keeping antagonists perpetually on guard. In many ways, the brave candor Gibbs embodied as an extension of Mark Harmon the actor‘s own values drove home truths other characters struggled to accept and rallied them to act accordingly.
Whether comforting a victim’s family or admonishing an admiral’s deception, Gibbs spoke and acted with conviction thanks to Harmon‘s ability to convey weighty themes impacting society through a primetime procedural lens. Fans tuned in by the millions each week knowing they could count on their stalwart guide steering through murky waters with well-honed moral clarity.
Of course, another signature part of the Gibbs persona that resonates so universally was his reliability as friend or mentor to guide those in need. Though often gruff in style and tone thanks to being an "old-school" marine, simple gestures behind the scenes revealed Gibbs‘ paternal instincts for the young agents following his path.
In one memorable arc when McGee struggled with self-doubt trying to write a novel, Gibbs not only refuted Tim‘s concerns but backed it with a hefty book advance to spur him on. Wise encouragement combined with decisive action to lift spirits defined Gibbs‘ brand of nurturing leadership that provided a role model to emulate for NCIS proteges and civilian viewers alike.
By pouring so much authentic humanity into Gibbs rather than a two-dimensional "hero", Mark Harmon‘s dedication to the role elevated both character and show to incredible heights over 20 seasons. Though CBS carries optimism that NCIS remains well-positioned to continue thriving, replacing such an indelible character who embodied key traits each week looks daunting without Harmon guiding the way.
Can NCIS Still Thrive Without Mark Harmon at the Helm?
Though clearly a central figure woven into the fabric of NCIS since its inception, losing Mark Harmon doesn’t inherently jeopardize the creative possibilities for showrunners going forward despite concerning fans. Plenty of contemporary examples illustrate replaced lead actors serving as catalysts for keeping viewers hooked rather than spelling a series’ demise.
Similar to fan furor over whether the Wonder Years could maintain charm without Fred Savage or if Dallas lost relevance without J.R. Ewing’s machinations, NCIS looks well-positioned to demonstrate plenty of gas left in the tank, albeit with some necessary adjustments. Executives emphasize the existing principal cast already boasts well-developed backstories and built sizable fanbases of their own ready to carry more storylines post-Gibbs.
They also point to the show’s long-running success stemming not solely from Harmon himself but an ecosystem combining clever scripts, sharp direction and production, and rich character depth beyond any individual. For evidence that transitioning from one lead face of a franchise holds promise, NCIS showrunners need only look to sibling show NCIS: Los Angeles which kept fans satisfied even swapping Harmon for Chris O’Donnell.
Rather than sputter without Cote de Pablo’s Ziva, producers leveraged her absence to showcase creative flexility. Fan-favorite characters Torres and Kasie emerged from expanded opportunity. Such examples provide templates for ably pivoting in Gibbs’ wake. While this next stretch without Harmon guiding Gibbs undeniably signals the close of one momentous chapter, the tools remain for enterprising writers and appealing characters to capably open another.
The only true certainties NCIS now faces is nothing can fully replace Mark Harmon‘s special contributions across 300 episodes. And should Gibbs wander back onto the scene for even a brief guest arc down the road? Millions would excitedly welcome him like reuniting with an old friend you never forget no matter how much time passes apart. Because in the end, there remains only one Leroy Jethro Gibbs.
What I‘ll Miss Most Without Harmon on My Screen Each Week
While writers, executives and fans share plenty about what Mark Harmon brought to defining Gibbs over 20 incredible seasons, part of processing his departure is reflecting on favorite moments that I‘ll cherish and miss witnessing on a weekly basis going forward.
Of course, the top memory seared into my mind will always be the epic showdown when Gibbs confronted Harper Dearing, the domestic terrorist mastermind behind several bombings. After skillfully maneuvering Dearing into admitting his role through classic interrogation moxie, justice got served swiftly when Gibbs killed him in cold blood rather than see trial.
The sequence distilled all Gibbs’ attributes into one cathartic scene expressing unwavering dedication to duty and country. When SECNAV Jarvis demanded Gibb’s badge for ignoring the system, Leon Vance summed up the ethos perfectly – “the system failed”. We cheered Gibbs’ morally clarity to place protection of the innocent over procedure.
I’ll also miss little moments revealing Gibbs’ tenderness that balanced his stoic marine grit. Despite reservations over bringing a dog into the office, by season two we watch Gibbs bond with the mascot Colonel, even indulging playful tug of war over chew toys. And hearing Gibbs utter “you’ll do” to Tony DiNozzo may hardly sound effusive, but for such an understated leader, it signaled touching respect and affection.
Of course I still hold out hope that we‘ve not seen the last of Gibbs or Harmon assuming the role when the perfect storyline entices him back. But whether on NCIS or future projects, Harmon leaves behind an extraordinary acting career filled with some of television’s most memorable characters. As Gibbs heads off into the Alaskan wilderness before our eyes, here’s hoping he’s simply turning the page to the start of an exciting new chapter rather patron saint of NCIS signing off once and for all.
