Actor Mark Harmon, best known for his iconic portrayal of Special Agent Leroy Jethro Gibbs on NCIS, is sharing stories about the real-life Naval Criminal Investigative Service that inspired the hit series. Harmon’s involvement with the show for nearly two decades gave him a unique perspective on the real agents and their work, which goes far beyond what’s depicted on screen.
Harmon’s portrayal of Gibbs, a no-nonsense leader with a deep moral code, was informed by his fascination with the real-life NCIS and the people who dedicate their lives to the service. Over the years, he built relationships with actual agents and gained insights into their work ethic, resilience, and the dangers they face daily. These interactions helped him bring authenticity to his role and fostered a deep respect for their work.
In a recent interview, Harmon reflected on how much he’s learned about the agency and its mission. “The real NCIS agents are some of the most dedicated and hard-working individuals you’ll ever meet,” he said. “Their stories are filled with courage, determination, and the kind of grit that’s hard to find anywhere else.”
Harmon has often mentioned that his portrayal of Gibbs was a tribute to these individuals, focusing on their quiet heroism and strong sense of duty. Though much of NCIS adds a layer of drama for entertainment purposes, Harmon has emphasized that the core of the show is rooted in the real agency’s values: justice, loyalty, and teamwork.
Now retired from his role on NCIS, Harmon has turned his attention to telling more stories about the real NCIS. Whether through interviews, behind-the-scenes features, or future projects, he remains committed to shining a light on the unsung heroes who inspired his work for so many years.
