10 Things You Didn’t Know About ‘NCIS’
8. Name Debacle
With many police procedural shows already going by acrononyms, such as CSI, it would be easy enough to have called NCIS just that. Instead, before the launch of the first season, the show was titled, Naval CIS, and then when it aired it was under the name Navy NCIS which stuck for the entire first season. Eventually CBS decided it was too redundant as the N stands for Naval anyway.
7. In The Family
In some episodes, there are shots of flashbacks featuring a young Gibbs played by Mark Harmon, and in order to make sure they actually looked similar, the younger version is portrayed by Mark Harmon’s real son, Sean. Meanwhile, Troian Bellisario, who plays Sarah McGee, is the daughter of NCIS producer and creator Don Bellisario, and his son Michael Bellisario took on the role of Charles “Chip” Sterling.
