The longevity of a television institution like NCIS is built on more than just clever scripts and high-stakes investigations; it is constructed on the shoulders of the incredible actors who brought the Naval Criminal Investigative Service to life. Since its debut in 2003, the show has become a global phenomenon, but the passage of over two decades means that the family of fans has had to say some truly difficult goodbyes. The phrase gone but never forgotten perfectly captures the legacy of the performers who have passed away, leaving behind a body of work that continues to resonate with millions of viewers in syndication and on streaming platforms. Honoring these seven stars is a way to celebrate the history of a show that has redefined the procedural genre.
At the very top of this list is the legendary David McCallum, who portrayed the beloved Chief Medical Examiner Dr. Donald Ducky Mallard for twenty seasons. McCallum was the soul of the series, a veteran actor who brought a sense of historical gravitas and eccentric wisdom to the morgue. When he passed away in 2023 at the age of 90, it felt like the end of an era. Ducky was more than a scientist; he was the team’s storyteller and conscience. His “Stellaride-like” bond with Mark Harmon’s Leroy Jethro Gibbs was the emotional backbone of the early years, and his absence remains a profound loss for the entire One NCIS community.
Another deeply felt loss was that of Miguel Ferrer, who played the stern yet deeply principled Assistant Director Owen Granger on NCIS: Los Angeles. Ferrer was a powerhouse performer who brought a gritty, noir-inspired energy to the West Coast spinoff. Even as he battled cancer in real life, he continued to work, allowing his character to face his own mortality with a dignity that moved audiences to tears. His passing in 2017 left a massive void in the leadership of the OSP, but his influence is still felt in the tough-love approach he instilled in the agents he oversaw.

A Legacy of Character and Charisma
The show’s history is also marked by the loss of Pauley Perrette’s on-screen father figure and the man who voiced the heart of the agency, Ralph Waite. Known globally for his role on The Waltons, Waite played Jackson Gibbs, the father of Jethro Gibbs. His appearances were rare but incredibly impactful, providing a rare glimpse into the vulnerability of the show’s stoic lead. When Waite passed in 2014, the show dedicated a beautiful episode to his memory, mirroring the real-life respect the cast had for this titan of the industry.
We also remember Vachik Mangassarian, a versatile character actor who appeared in multiple roles across the franchise, most notably in the flagship series and NCIS: Los Angeles. His ability to blend into diverse and challenging roles made him a staple of the procedural world. His death in 2022 was a reminder of the many character actors who provide the essential texture and realism that allow the main stars to shine. Similarly, the loss of Terrence Hardy Jr., a young talent who appeared in the early years, reminded fans that the NCIS family spans multiple generations of performers.
Honoring the Voices and the Villains
The franchise was also touched by the passing of Gregory Itzin, who played Director Charlie Bloom. Itzin was a master of playing complex authority figures, and his time on NCIS added a layer of political intrigue that helped elevate the series during its mid-season peak. His death in 2022 was mourned by fans who appreciated the intellectual weight he brought to the screen. Every procedural needs a strong moral compass and a formidable challenge, and Itzin provided both with effortless grace.
Finally, we honor Ravil Isyanov, a recurring guest star who played the Russian mobster Anatoli Kirkin on NCIS: Los Angeles. Isyanov brought a touch of theatricality and dark humor to the show, becoming a fan favorite despite his character’s criminal leanings. His passing in 2021 was a blow to the spinoff’s recurring cast, which thrived on the unique energy he brought to every scene. These actors may have played different roles—some heroes, some mentors, and some antagonists—ưng they all contributed to a tapestry of storytelling that has stood the test of time.
A Forever Connection With the Fans
The reason NCIS remains at the top of the recommendation lists for fans of quality drama is because of the humanity these actors infused into their roles. When we watch old episodes, we aren’t just seeing characters; we are seeing the passion and dedication of artists who loved their craft. The show has a unique ability to make the audience feel like they are part of the team, which makes the loss of these stars feel like losing members of our own extended family.
As the NCIS universe continues to expand with new spinoffs and seasons, the legacy of David McCallum, Miguel Ferrer, Ralph Waite, and others serves as a guiding light. They set the standard for excellence that current and future cast members strive to meet. Their work is immortalized in the frames of the show, and as long as there is a fan watching a late-night rerun, their light will never truly go out.
