Austin Stowell has been cast as a young Leroy Jethro Gibbs in CBS' upcoming NCIS prequel series, NCIS: Origins. The series, set to air in the 2024-2025 broadcast season, will delve into the years before NCIS, starting in 1991. Stowell will portray Gibbs as he embarks on his career as a special agent on a team led by NCIS legend Mike Franks.
Mark Harmon, who originally played Leroy Jethro Gibbs in NCIS, will return to the series to narrate. Harmon, who starred in NCIS for 19 seasons before departing in 2021, cited a desire to spend more time at home as a key factor in his decision to leave the show.
