NCIS '90s Prequel Lands Mark Harmon for Season-Long Arc

Mark Harmon will return as Leroy Jethro Gibbs for a season-long arc in the upcoming NCIS: Origins series, which is set to premiere on Tuesday, October 6 at 10 p.m. ET/PT. The showrunner confirmed Harmon's involvement, stating it was a long-discussed idea that Harmon was excited to pursue to give fans what they desired. The series will explore Gibbs' past in the 1990s, featuring events at Camp Pendleton, while simultaneously presenting a present-day mystery that begins to unravel his peaceful retirement in Alaska. The premiere episode is titled "Don't You Forget About Me."

This season will heavily lean into '90s nostalgia, even recreating a Blockbuster Video for certain scenes, aiming to evoke fond memories for the audience. Alongside the compelling cases and action sequences, the show will delve into character stories, particularly focusing on the complicated relationship between the younger Gibbs (Austin Stowell) and Lala (Mariel Molino) following their kiss. The possibility of cameos from other NCIS legends is also being considered, adding to the excitement for dedicated fans.
