Mark Harmon Breaks Silence – Confirms Longstanding Rumors about season 21!

Mark Harmon is returning to NCIS, but not as fans might expect. Instead of reprising his role as Gibbs, Harmon will narrate an NCIS prequel titled “NCIS: Origins,” focusing on a younger Gibbs in 1991. The series, produced by Harmon’s son Sean, will explore Gibbs’ early career at NCIS Camp Pendleton.

Harmon’s involvement in the prequel marks his return to CBS, with the series set to delve into Gibbs’ backstory while reintroducing fan-favorite characters. Despite speculation about Harmon’s return to the main series, his role remains uncertain as he explores other projects, including writing his upcoming book, “Ghosts of Honolulu.”
