TheNCISfranchise is a massive institution, so it’s no wonder some actors have played multiple characters within its expansive storyline. It would throw off the narrative in most television shows to have the same person appear as different characters, with many only running for a few years. However,NCIS’ rich tapestry of more than two decades on television allows actors to weave in and out of the narrative as differentNCIScharactersseamlessly. Moreover,the fact thatNCIShas so many spinoffs means some actors can always show up on a different show as a new character.

The franchise has tackled over a thousand cases betweenNCISand its many spinoff shows, meaning there have been thousands of opportunities to play a character attached to a weekly case. The television institution continues to grow, expanding opportunities for its favorite actors to return without compromising the integrity of its complex web of narratives.Even fan-favorite characters like Timothy McGee and Mike Franks once had their actors play different roleswithin thesharedNCISuniverse, adding another layer of complexity to their established presence.
