In 2021, Mark Harmon left NCIS after 18 years. And it looked like his time with the franchise was over. However, the actor appeared twice in the prequel series that he narrates.

Today, CBS announced that his mug is returning to our televisions. The actor 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 throughout the season.

Can Harmon save the spinoff? We shall see…

Earlier this week, CBS announced that Mark Harmon will reprise his role as Leroy Jethro Gibbs on NCIS: Origins. Today, they shared a photo of him dressed up as the character he played for over 18 years, and I can’t believe we have not seen him like that for four years.

So what would bring Harmon out of on-camera retirement (he is the narrator on the prequel)? His return is for a crossover episode between NCIS: Origins and NCIS: OG.

When a naval officer mysteriously dies in the ‘90s, Gibbs (Austin Stowell) and the team travel to the small dust-blown town of Serenity, Calif., where they encounter secret-harboring residents, an uncooperative sheriff and an investigation that will reverberate for decades.

The one-night event airs on Veterans’ Day.

Before Mark Harmon was famous in his own right, he made his on-camera debut with his dad, NFL Player Tom Harmon, and his mom. How cute was that 1972 commercial?

Before Mark Harmon was fighting crime in DC in NCIS, he started out doing it in LA in 240-Robert. How much did you love hearing the 27-year-old sing in that 1979 episode?

NCIS is taking it back to the beginning for its latest spinoff from the beloved franchise.

Since 2003, we have seen NCIS branch off with NCIS: LA, NCIS: NoLa, NCIS: Hawaii, and NCIS: Sydney. And coming to the 2024-2025 season on CBS, we will see where it all began with NCIS: Origins.

NCIS: Origins begins in 1991, years prior to the events of NCIS and follows a young Leroy Jethro Gibbs, narrated by Mark Harmon. In the series, Gibbs starts his career as a newly minted special agent at the fledgling NCIS Camp Pendleton office where he forges his place on a gritty, ragtag team led by NCIS legend Mike Franks.

“We are elated and honored to continue the expansion of the NCIS universe in such a unique and unexpected way,” said Amy Reisenbach, president of CBS Entertainment. “Viewers can look forward to Mark Harmon returning to CBS to narrate the complex and mysterious backstory of Leroy Jethro Gibbs’ early years in NCIS: Origins, which will build on the rich legacy of this character while reintroducing fan-favorite characters and meeting new ones.”

CBS has not begun to cast the show, so who do you think should play young Leroy Jethro Briggs? I think Gale Harold would be a good choice.

This is the second new series that CBS announced for next season. The first was Watson, based on Sherlock Holmes’ partner, who is back working as a doctor.
