Since its 2003 premiere, NCIS has developed into one of the most popular crime dramas on television, and its cast has become legendary. Gibbs’s actor, Mark Harmon, left the show but is still an executive producer and is working on other projects.
Longtime fans will be thrilled when Michael Weatherly returns to star opposite Cote de Pablo in the upcoming NCIS: Tony & Ziva spinoff. While David McCallum’s enduring impact as Ducky is still greatly appreciated by viewers, Pauley Perrette resigned from performing to concentrate on humanitarian activities.
Wilmer Valderrama, Emily Wickersham, Brian Dietzen, and Sean Murray have all transitioned into other positions, side projects, and artistic endeavors. The cast’s development from 2003 to 2025 demonstrates how far the franchise and their careers have progressed.
