Mark Harmon hasn’t faded from our TV screens after all.
CBS says he’ll appear — at least a bit — in every episode of next season’s “NCIS: Origins.” That’s in a two-era story, going from the 1990s to modern times.
Harmon did 18 seasons of “NCIS,” departing as his character (Leroy Jethro Gibbs, shown here) dropped out to live in the Alaskan wilderness.
Then came “Origins,” showing Gibbs’ early years in what’s now the NCIS. Harmon narrates, but has been on-camera only twice — in the opener and in a crossover that started a mystery on “Origins” and solved it on “NCIS.”
Now that same approach — a mystery from the ’90s, confronted three decades later — will span the new “Origins” season.
Mark Harmon, who starred as Leroy Jethro Gibbs for 18 seasons on NCIS, returns for the next chapter in the iconic character’s story this fall. Harmon will appear in all episodes of NCIS: ORIGINS this season as part of a present-day mystery tied to his ‘90s Camp Pendleton days in an action-packed story that unfolds all season long. Season three of NCIS: ORIGINS will air Tuesdays at 10:00 PM, ET/PT this fall on CBS and streaming on Paramount+. Pictured (L-R): Mark Harmon as Leroy Jethro Gibbs.
