The future of ‘NCIS’ after Mark Harmon’s departure remains uncertain. Showrunners may either promote an existing character like Agent McGee or bring in a new actor to take on the leadership role.
Promoting an existing character offers familiarity, with Agent McGee or possibly Tony DiNozzo being strong contenders. This approach would keep the show connected to Gibbs and honor Mark Harmon’s legacy.
On the other hand, casting a new actor could bring fresh appeal to the series and potentially attract new viewers. It could also allow the show to take a different direction, with a new character and storyline, either revitalizing the series or risking fan disapproval.
