Mark Harmon, celebrated for his iconic portrayal of Special Agent Leroy Gibbs since NCIS premiered in 2003, has been a central figure in the franchise.
Despite past conflicts with co-stars, his exit in season 19 left fans speculating about a possible return. In March 2024, CBS Entertainment President Amy Reisenbach hinted at the potential for Harmon’s comeback, noting both his legendary role and the boost it would bring to ratings. His involvement as the narrator for the prequel NCIS: Origins further fuels hopes that Harmon may soon return to the series.
