For nearly two decades, Leroy Jethro Gibbs served as the main protagonist on NCIS , and now the character will soon be taking center stage on the 2024 TV schedule . This time around, though, it’s Austin Stowell playing a younger Gibbs , with the prequel NCIS: Origins following along with him in 1991. However, not only is original Gibbs actor Mark Harmon involved in Origins as both narrator and one of the executive producers, word came in today that he’ll also appear in the series premiere, and I’m looking forward to learning what the present-day Gibbs has been up to since he exited NCIS early in Season 19 .

Mark Harmon Will Be On Camera During NCIS: Origins' Premiere As already mentioned, we’ve known that Harmon’s voice will be present throughout NCIS: Origins since the older Gibbs will be recounting his early time working for the title law enforcement agency, known back then as NIS. Today, though, co-showrunner David J. North shared to reporters, including CinemaBlend’s own Laura Hurley, at the CBS Fall 2024 Virtual Press Day that Harmon will briefly appear in Origins ’ first episode.

He explained: That was a discussion between Mark, myself and Gina Monreal. I hope the audience will be excited to see him after so many years. While it’s nice to know that Harmon will reprise Leroy Jethro Gibbs on camera, don’t expect this to become a regular thing on NCIS: Origins .

While North and fellow showrunner Gina Moreal are “open to anything” when it comes to Harm.
