Why did Mark Harmon leave the show?

In an exclusive interview with Entertainment Tonight, Mark Harmon opened up for the first time about his exit from NCIS last fall. He stated, “What has always drawn me here is the character I play and to keep it fresh and to keep it challenging,” the 70-year-old actor said in the clip, before alluding to the possibility that it was time to close this chapter in his career — for now. “Plot-wise, this character has taken the path that it did. I thought it was honest and OK with.” Harmon then assured NCIS fans Gibbs is still alive and kicking, enjoying the simpler things in life: “I’m not retired… The character is living in Alaska as far as I know.”

Additionally, he also acknowledged that he was “not sure” how long he would be gone, quote, “My gut’s telling me, I’ll know when I find it,” Gibbs said of what exactly he’s looking for. “This sense of peace, I have not had this since Shannon and Kelly died and I’m not ready to let it go.” He then offered his protege the unofficial reins of the NCIS office. “I could not have hoped for anyone better to watch my back for the past 18 years than you,” he said to McGee.

Binder issued a statement, leaving the door open for a future comeback, quoting, “As an executive producer and dear friend, Mark continues to be an integral part of the fabric of the show. Our north star has always been staying true to our characters, and that truth has always guided the stories we tell and where those characters go,” Binder said in a statement to ET. “So regarding the future of Gibbs, as longtime fans of the show may have noticed over the years… never count Leroy Jethro Gibbs out.”
