How NCIS Stars REALLY Feel About Mark Harmon..

From his debut as Leroy Jethro Gibbs in 2003 to his departure in 2023, Mark Harmon made NCIS a cultural phenomenon. Fans believed he’d stay until the end, but Harmon left, leaving behind memories of TV’s assertive yet fatherly detective. Off-screen, he was a mentor to his co-stars.

Cote de Pablo, who played Ziva David, saw Harmon as a friend and mentor, mirroring their on-screen father-daughter bond. Michael Weatherly, who portrayed Tony DiNozzo, noted their differing personalities but appreciated Harmon’s advice for his role in Bull. Sean Murray, playing Timothy McGee, viewed Harmon as a mentor, recalling their first meeting 30 years ago on Hearts of the West. Harmon’s departure hit Murray hard, as he now becomes the longest-running star on NCIS.

Harmon’s exit was due to his desire to step back, leading to his character relocating to Alaska. CBS hinted he might return for special episodes. Harmon’s wife, Pam Dawber, praised his genuine and supportive nature on set. However, not all relationships were smooth; Pauley Perrette (Abby Sciuto) left the show after conflicts with Harmon, notably over his dog biting a crew member.

Brian Dietzen, who plays Jimmy Palmer, described Harmon as the backbone of NCIS and expressed gratitude for their long-standing friendship. Despite many changes, Harmon’s influence and leadership were deeply felt by the cast and crew.
