If you thought Mark Harmon was done with the world of acting after stepping away from NCIS, think again. In a surprising turn of events, the iconic actor has reignited his passion for the screen, making a splash with his recent cameo on NCIS: Origins. According to an exclusive source from Closer, this wasn’t just a one-time deal—it’s the beginning of something bigger.
You see, life after retirement wasn’t all it was cracked up to be for Mark. “He quickly realized that tinkering around the house and tackling home repairs just wasn’t cutting it,” the insider explains. “Working with his former colleagues on NCIS: Origins reinvigorated him in a way that retirement simply couldn’t match. Now, not only does he want to do more cameos on NCIS, but he’s also exploring new opportunities in acting and producing. This isn’t just a hobby for him anymore—it’s a full-blown career renaissance.”
From Gibbs to... Gibbs Redux?
Let’s rewind a bit. Mark Harmon, the man who brought the legendary Leroy Jethro Gibbs to life for 19 seasons on NCIS, officially hung up his badge in 2021. But that didn’t mean the character—or the franchise—was ready to let him go. Enter NCIS: Origins, where Austin Stowell steps into the shoes of a younger Gibbs. And while it might seem like Mark’s chapter was closed, his brief return to the screen proves otherwise.

Mark’s decision to step back into the world of Gibbs wasn’t made lightly. “He was hesitant at first,” a second source reveals. “But the moment he stepped onto the set, it was like riding a bike. The showrunners knew how special this opportunity was, so they pulled out all the stops to make sure Mark felt welcomed and valued. They weren’t just bringing him back—they were rolling out the red carpet.”
And let’s be real here: Mark Harmon is no ordinary guest star. The production team has gone above and beyond to cater to his every need. From hiring a masseuse to ensuring there’s always fresh espresso available, the crew has done everything in their power to keep him comfortable. “They’ve bent over backward to make sure he feels at home,” the source confirms. “And it’s working. Mark’s loving every second of it.”

A Family Affair: The Harmon Legacy Continues
It’s not just Mark who’s keeping the NCIS flame alive. His son Sean has also joined the family business, taking on a producer role for the new spin-off. This deep-rooted connection to the franchise has clearly rekindled Mark’s enthusiasm. “He sees this as a fresh start,” the source elaborates. “For Mark, this isn’t just about coming out of retirement—it’s about embracing a new chapter in his career. And he’s got all the support he needs from his wife, Pam Dawber, and his sons.”
But it wasn’t always this way. During his time away from the screen, Mark dabbled in writing, co-authoring a historical book titled Ghosts of Honolulu: A Japanese Spy, a Japanese American Spy Hunter, and the Untold Story of Pearl Harbor with retired NCIS special agent Leon Carroll Jr. While the project may have offered a temporary escape, it wasn’t enough to quench his thirst for acting. “Let’s face it,” the source adds, “a lot of retirees get bored real fast with retirement, and Mark’s no exception. Golf and home repairs just weren’t cutting it.”
