Cote de Pablo, who played Ziva David on NCIS for almost a decade, left in 2013 due to dissatisfaction with the character’s direction and political issues. Despite sporadic returns, she emphasized the need for a great storyline to consider a full-time return.

Michael Weatherly’s potential return as Special Agent Anthony DiNozzo is speculated after the cancellation of “Bull,” and executive producer Steven D. Binder is open to the idea.

Mark Harmon left the role of Leroy Jethro Gibbs after 20 years but remains an executive producer. Rumors persist about his potential return, as Gibbs is alive and well in Alaska.

In a surprising twist, Harrison Ford was initially considered for the role of Gibbs, but Mark Harmon ultimately took on the iconic character.
