The first international series in the NCIS franchise, NCIS: Sydney, is set to premiere on November 14. Although a crossover between the different NCIS shows is logistically challenging due to the vast distance, showrunner Morgan O'Neill says they have discussed the possibility. The show aims to showcase the beauty and uniqueness of Sydney. While there may not be a crossover yet, fans can still expect Easter eggs throughout the first season and potentially in future seasons as well, adding to the overall enjoyment of the franchise. NCIS: Sydney premieres on September 14 on CBS.
