NCIS - Unità anticrimine

Pauley Perrette, who plays Abby, actually graduated from college with a degree in Forensics, and then moved to New York to get her master's, and it was there that she got in to acting, before coming to NCIS. Producers have said that most of the personality and interests displayed by Abby come from Perrette just playing herself.

In the episode "Hiatus Part 2" it is revealed that Gibbs joined NIS (changed the same year to NCIS) in 1992 following the death of his wife and daughter. However, in the JAG episode "Ice Queen" in 2003 he tells Lt.Cmdr. Rabb that he has been an agent for 19 years, which would mean he would have joined NIS in 1984.

This definition appears in the opening credits of season 1; The Naval Criminal Investigation Service [NCIS] is a worldwide federal law enforcement organization whose mission is to protect and serve the Navy and Marine Corps and their families. To counter the evolving threats NCIS has implemented a new proactive strategic plan which emphasizes the following priorities; -Prevent terrorism and related hostile acts against DoN forces and installments -Protect DoN systems and information against compromise -Reduce criminal activity and mitigate the impact on Navy and Marine Corps operational readiness

The original pilot, a 2-parter in JAG, was re-cut into a single-episode and shown in the middle of the first season.
