The NCIS universe is expanding once again, and fans are buzzing after CBS unveiled the very first look at NCIS: Origins. The highly anticipated prequel will follow a young Leroy Jethro Gibbs in 1991, as he begins his career at Camp Pendleton. The initial images and teaser gave viewers their first glimpse of actor Austin Stowell stepping into the shoes of Gibbs—complete with the familiar intensity and quiet strength that longtime fans know so well.

What makes the reveal even more special is Mark Harmon’s involvement. Harmon, who played Gibbs for nearly two decades, is not only an executive producer on the series but also narrates the show, serving as a bridge between the original NCIS and its prequel. After the first-look footage dropped, Harmon shared his thoughts, praising Stowell’s performance and saying that he immediately “felt the room change” when the young actor auditioned. According to Harmon, Stowell captures the essence of Gibbs while adding a fresh, layered perspective.

For fans who were heartbroken when Harmon left NCIS in Season 19, this spinoff feels like both a tribute and a continuation of the character’s journey. The series promises to dig deeper into Gibbs’ backstory, showing how personal tragedy and early cases shaped the man he would become. Harmon himself has said that returning to Gibbs’ origins has been “emotional” and admitted he sees it as a way of keeping the character alive in a new form.

With Harmon’s blessing and guidance, NCIS: Origins looks poised to deliver a powerful blend of nostalgia and discovery. If the first look is any indication, fans are about to witness Gibbs’ evolution from a determined young Marine to the legendary leader who became the heart of NCIS.
