It’s hard to explain to anyone under 20 just how much NCIS dominated the living room. For a solid decade, it wasn’t just a show; it was background noise for the entire country. At its peak, 21 million people were tuning in every week to watch a silver-haired guy in a polo shirt slap his coworkers on the back of the head.
But 20 years is a long time to stay in one office. Most of the original team has long since moved on, some to quiet retirements and others through the kind of messy exits that usually stay behind closed doors.
The Boss Who Never Really Left
Mark Harmon was the show. For 19 seasons, he played Leroy Jethro Gibbs as a man of few words and even fewer hobbies (unless you count building boats in a basement with no exit). When he finally left in 2021, it wasn’t with a bang. He just sort of faded into the Alaskan wilderness.
These days, Harmon is leaning into the “elder statesman” role. He’s not on screen much, but he’s still the puppet master behind the scenes as an executive producer. He even narrates the new prequel, Origins, proving that even when Gibbs retires, he’s still the one telling the story.
The Messy Breakup
If you want to talk about the “NCIS Drama,” you’re really talking about Pauley Perrette. For 15 years, she was Abby Sciuto—the pigtail-wearing, Caf-Pow-chugging heart of the series. Then, in 2018, it all went south.
Her exit was public and painful. There were vague tweets about “multiple physical assaults” and a very real, very weird rift involving Mark Harmon’s dog. Since then, Perrette has basically washed her hands of Hollywood. She did one sitcom that didn’t stick, and now she spends her time on activism and staying far away from film sets. She seems a lot happier without the lab coat.
The ‘Tiva’ Long Game
Then there are Michael Weatherly and Cote de Pablo. For years, the “will-they-won’t-they” tension between Tony and Ziva was the only reason half the audience was watching.
Weatherly left to lead his own show, Bull, which was successful but plagued by its own behind-the-scenes legal settlements. De Pablo left earlier, reportedly because she didn’t like where her character was heading. But they both seem to realize that their chemistry was lightning in a bottle. They’re currently filming a spin-off in Europe, finally giving the fans the “Tiva” ending they’ve been arguing about on forums for fifteen years.
The Last Man Standing
Sean Murray is the true anomaly. He started as “Probie” McGee—the tech nerd who everyone picked on. Twenty-two years later, he’s still there. He’s watched his costars leave, get written off, or pass away, yet he’s still showing up to the Navy Yard every day. He’s not a tabloid fixture and he doesn’t have a flashy spin-off, but there’s something impressive about being the one person who stayed to keep the lights on.
The Empty Desk
Finally, there’s David McCallum. Ducky was the show’s soul, a link to an older era of television. McCallum worked right up until he passed away at 90 last year. When the show finally addressed his death, it felt like the end of an era. You can replace a lead actor, but you can’t replace that kind of history.
Gibbs had a rule about never looking back once you walk away. But for this cast, that’s proven impossible. Whether they left on good terms or bad, NCIS is the kind of shadow you never really step out of.
