In the vast landscape of television, certain shows become ingrained in our lives, evolving into cultural phenomena we can’t fathom living without. One such stalwart is the CBS military procedural crime-fighter series, “NCIS,” short for Naval Criminal Investigative Service. Debuting in 2003 as a spinoff of the naval courtroom drama “JAG,” “NCIS” has become an enduring success, boasting over 400 episodes and multiple spinoffs, earning the distinction of being the world’s most-watched drama.

However, the longevity of a series often witnesses cast turnovers, some more dramatic and controversial than others. One notable departure was that of Cote de Pablo, who bid farewell to her character, Ziva David, in 2013. Fans, devastated by this exit, attempted to reverse her decision by sending paper clips to CBS, referencing a memorable scene from Season Four.

Similarly, Michael Weatherly, embodying Senior Field Agent Anthony DiNozzo, left the series in 2016 after 13 years, expressing a desire for new challenges. Pauley Perrette’s departure in 2018, after over 350 episodes as the quirky forensic scientist Abby Sciuto, was driven by a dark revelation – she had experienced multiple physical assaults during her time on the show.

Duane Henry, portraying NCIS Liaison Officer Clayton Reeves, found his exit in 2018 a life-changing opportunity, citing a desire for more diverse roles. Sasha Alexander, who portrayed Special Agent Caitlin Todd, left in 2005, seeking relief from the grueling TV series shooting schedule.

Lauren Holly, who played Director Jenny Shepard, departed due to shifting dynamics within the show and her growing boredom with the role. Jennifer Esposito’s departure after a single season as Special Agent Alex Quinn raised questions, as she initially stated it was a limited gig, but rumors suggested deeper reasons.

The unsettling departure of Zoe McLellan, who portrayed Agent Meredith Brody in “NCIS: New Orleans,” revealed the ugly side of the industry. Allegedly fired because an executive found her unattractive, this incident shed light on the problematic power dynamics within the entertainment industry.

“NCIS” remains a television titan, but behind the scenes, these departures unveil the complex interplay of personal, creative, and sometimes, disturbing factors that shape the trajectory of a long-running series.
