NCIS fans are always thrilled when it's confirmed that the CBS show will be returning for another season. But while the show's longevity is certainly impressive, it also means that it has lost several cast members over the years. 

Have you ever wondered why they left and where they are now? From Michael Weatherly and Cote de Pablo to Pauley Perrette  and Mark Harmon, find out what the actors who have left the hit CBS series are up to now...

Mark Harmon

Mark Harmon left NCIS viewers devastated in 2021 when it was announced that after almost two decades as the military police drama's lead, he was taking a major step back and retiring from the team.

In the fourth episode of season 19, Leroy Jethro Gibbs decided to retire from law enforcement and spend the rest of his days in scenic Alaska, where his last case had led him. 

However, following Mark's onscreen departure, showrunner Steve Binder released a statement that heavily suggested Gibbs could make a comeback in future seasons. It read in part: "Regarding the future of Gibbs, as long-time fans of the show may have noticed over the years… never count Leroy Jethro Gibbs out."
