Overview
- CBS confirmed on June 30 that Mark Harmon will appear on camera in every episode of NCIS: Origins Season 3 as the present‑day Leroy Jethro Gibbs.
- The 10‑episode fall season centers on a single mystery that connects Gibbs’ 1990s Camp Pendleton past to a present‑day investigation and will play out across all episodes.
- David J. North will serve as showrunner and executive producers for Season 3 include Mark Harmon, Sean Harmon, Michele Greco and Eric Christian Olsen, who joined under his Cloud Nine banner.
- CBS scheduled the series for a Tuesday 10 p.m. ET broadcast slot this fall with next‑day streaming on Paramount+, reflecting a compact 10‑episode order.
- Harmon’s full‑time return leverages his 18‑season legacy with NCIS to boost the prequel’s profile and positions Origins to resolve or extend Season 2’s dramatic cliffhangers while testing a more serialized direction for the franchise.
