There is little doubt that "NCIS" is a huge and beloved television show. The very original "NCIS" aired all the way back in 2003, and it is still running today. But it has also produced some really great spinoffs like "NCIS: Los Angeles" and of course, "NCIS: New Orleans." But there is something special about the New Orleans spinoff. Unlike the other versions of the show, this one is actually filmed on set in New Orleans! Others are filmed on a sound stage.
