For over two decades, Leroy Jethro Gibbs has been the backbone of the NCIS universe, and now fans are getting a major treat. Mark Harmon, who stepped away from the role in 2022, is officially returning to the franchise in NCIS: Origins Season 3. The first-look images have just dropped, and they promise a storyline that pulls Gibbs out of his Alaskan retirement and back into the action.
The prequel series, which debuted in late 2024, stars Austin Stowell as a younger Gibbs, chronicling his early days at Camp Pendleton. But Season 3 is set to bridge the gap between past and present, with Harmon's older Gibbs taking center stage. According to showrunner David J. North, Harmon won't just be making a cameo—he'll be a prominent presence throughout the season. North teased that the events unfolding in the present day are "directly tied" to Gibbs's 1990s experiences, and they "may be enough to pull him out of retirement."
The season premiere, titled "Don't You Forget About Me," is scheduled to air on CBS on October 6, with episodes streaming on Paramount+ the following day. The episode will be set in the present day, showing Gibbs as the ghosts of his past catch up to him. The newly released images capture Harmon in familiar territory—rugged, stoic, and ready for whatever comes his way.
This return is a significant moment for the franchise, which has seen its fair share of spin-offs and crossovers. While the original NCIS continues to thrive with over 500 episodes, Origins offers a fresh perspective on the beloved character. Harmon's involvement adds a layer of continuity that fans have been craving since his departure.
For those who've followed Gibbs's journey from JAG to the flagship series, this return feels like a homecoming. The character's evolution—from a driven young agent to a seasoned mentor—has been a cornerstone of the show's appeal. Now, with Harmon back in the fold, Origins Season 3 promises to explore the unresolved threads of his past while setting the stage for what's next.
As the premiere date approaches, anticipation is building. Will Gibbs's retirement be permanently disrupted? What secrets from his Camp Pendleton days will resurface? Fans won't have to wait long to find out. In the meantime, they can catch up on the first two seasons of NCIS: Origins on Paramount+.
Mark Harmon's return is a reminder of why the NCIS franchise remains a ratings powerhouse. With a compelling storyline and a beloved actor back in the spotlight, Season 3 is shaping up to be a must-watch event. Stay tuned for more updates as the premiere draws near.
