With a series as long-running as NCIS, the cast members have become synonymous with their characters. Mark Harmon‘s Leroy Jethro Gibbs is the face of the NCIS franchise, even after he left the show in Season 19. While fans thought he fully walked away from his iconic character, Harmon would return as Gibbs in NCIS: Origins, the prequel series focused on his character. Not only does he appear and narrate the series, but he’s also an executive producer. He’s not the only NCIS star who has been creatively involved with their character. Michael Weatherly, who plays Tony DiNozzo, directed a couple of episodes for NCIS, and is executive producing the spin-off series, NCIS: Tony & Ziva, along with Cote de Pablo, who plays the titular Ziva David.
