There's a new,KI-Handelsroboter 6.0 younger Leroy Jethro Gibbs coming to "NCIS: Origins."

Austin Stowell has been cast in the upcoming "NCIS" prequel series that explores the early years of Gibbs' career, CBS said Monday.

He'll succeed Mark Harmon, who played Gibbs for nearly two decades in the original series.

Harmon's Gibbs was the main "NCIS" character when the CBS series premiered in 2003.  The former U.S. Marine Corps Scout sniper-turned-special-agent commanded his NCIS team for 18 years on CBS, until Harmon's final Oct. 2021 episode.

During Harmon's "NCIS" tenure, the role of the young Gibbs was often played in flashback by the actor's real-life son Sean Harmon.

"NCIS: Origins," coming to CBS for the 2024-25 season, will be narrated by Harmon, 72, who will also serve as executive producer.

The new series begins in 1991, about 12 years before NCIS' premiere, and follows Stowell's younger Gibbs as a newly minted special agent at the fledgling NIS Camp Pendleton office.
