The original NCIS has been going since 2003, with two successful spin-offs. Now another is apparently in the works in NCIS: Hawaii.

It isn’t a huge surprise, when you consider that the main series is the most watched on US television, and NCIS: Los Angeles and NCIS: New Orleans continue to get millions of viewers in front of teevs.

The news of this possible fourth series in the franchise comes via Deadline, who report that the new NCIS will feature a wholly new cast, and that it isn’t planned to be introduced via an episode of any of the existing series.

This actually wouldn’t be the first time that we’ve seen the island state in the NCIS universe, as there was a 2012 crossover episode between NCIS: Los Angeles and Hawaii Five-0 (pictured above).
