Another NCIS series starring John Corbett got a backdoor pilot on NCIS: LA, but was not ordered to series.
NCIS: LA got its start with two episodes of NCIS Season 6 in 2009, and NCIS: NOLA launched with two episodes of NCIS Season 11 in 2014.
A fourth NCIS series is developing at CBS to be set in Hawaii, according to Deadline, which further reports that NCIS: Hawaii is not planned to debut as a backdoor spinoff.
That’s not the case for NCIS: Los Angeles or NCIS: New Orleans, both of which debuted in backdoor pilot events that aired as NCIS two-parters.
