He’s back! After four long years away from the screen, Mark Harmon is officially stepping back into his legendary role as Special Agent Leroy Jethro Gibbs for a very special “NCIS” franchise crossover this November.

The highly anticipated event airs Tuesday, November 11 – fittingly on Veterans Day – and marks the first-ever crossover between “NCIS” and its prequel series “NCIS: Origins.”

The night kicks off with “Origins,” where Austin Stowell stars as a young Gibbs navigating the 1990s while investigating the mysterious death of a naval officer in a small town. Then, in a thrilling twist, the storyline jumps to the present day on “NCIS,” where the same case is suddenly reopened – and Gibbs returns to the action.

Although Harmon stepped away from his on-screen role in 2021 after 18 seasons, he’s remained deeply involved behind the scenes, serving as executive producer and narrator for “NCIS: Origins.”

Showrunners David J. North and Gina Lucita Monreal teased Gibbs’ return, saying, “Four years ago, Gibbs disappeared to Alaska to live a life of solitude. We know how much fans have missed him and wondered what he’s been up to. We don’t want to spoil anything, but let’s just say – Gibbs is no longer alone.”

Fans, get ready – Gibbs is back, and this is one NCIS event you won’t want to miss.
