Mark Harmon is making a comeback to NCIS, but in a surprising new role. He’ll appear in NCIS: Origins, a prequel series that explores a young Leroy Jethro Gibbs as he embarks on his career with the Naval Investigative Service in the early ’90s. Set over a decade before the flagship series, Harmon will take on the role of executive producer and narrator.
Showrunner David J. North reveals that the first episode will feature brief video clips of the older Gibbs, with the potential for more appearances in future episodes. Harmon’s involvement provides fans with a familiar face to guide them through Gibbs’ origin story, making this a nostalgic treat for long-time viewers eager to see their favorite character’s early days.
