Mark Harmon will return as Leroy Jethro Gibbs in a new NCIS spin-off. Teaming up with his son, Sean Harmon, the duo have been given the green light on NCIS: Origins – a prequel series set in 1991. Following a young Gibbs as he embarks on a career at the NCIS Camp Pendleton office, the series will also trace the character's blossoming friendship with his mentor, Mike Franks.
Following a similar format to Young Sheldon, Mark will reprise his iconic role as a narrator in the series. Meanwhile, his son, Sean Harmon – who previously portrayed a younger version of Gibbs in NCIS – will turn his attention to executive producing.
With this in mind, casting will allow another actor to step into Gibbs' legendary shoes.
"The character of Gibbs has been an important part of my life for 20 years, both in watching my father craft the role and previously having the honor to play young Gibbs myself," Sean, 35, said.
"I always felt there was a tale worth telling about his earlier years, so I am thrilled to be stepping into a producing role alongside [NCIS writers-producers] Gina [Lucita Monreal], David [J. North] and my dad as we tell this story and reveal a new side of this beloved character."

Explaining that the opportunity to tackle "fresh" and "challenging" material is what kept him returning to the drama every season, Mark alluded to the possibility that after almost two decades on the show, he no longer felt that was the case.
"What has always drawn me here is the character I play and to keep it fresh and to keep it challenging," he said, before clarifying that he believes his beloved character is "not retired".
"Plot-wise, this character has taken the path that it did. I thought it was honest," added Mark.
