Mark Harmon reflects on passing NCIS Gibbs role

Mark Harmon, who portrayed Leroy Jethro Gibbs for 19 seasons on NCIS, is reflecting on his transition to a narrator and executive producer role for the prequel series, NCIS: Origins. Premiering in 2024, Origins features Austin Stowell as the young Gibbs. Harmon expressed that it is 'OK' if the new cast does not rely on him for performance guidance, acknowledging that 'this is a different show' with a distinct group of actors.

He highlighted the talent of the Origins cast, noting their thorough research into the NCIS franchise's history. Harmon also pointed out the familiar connection to showrunner David North, who began as a script runner on the original NCIS before rising to writer and executive producer, and subsequently co-created Origins.
