NCIS star David McCallum, the last original cast member, passed away at 90 due to natural causes. His final iconic scene in the season 20 finale featured a pivotal dialogue.
In the episode, he revealed a terrorist group’s plan for a “Black Sky event” via a video link. Although his character had reduced on-screen appearances, NCIS bosses hinted at a possible return for him. Executive producer Charles Floyd Johnson mentioned that David, now 90, might return for a few episodes but acknowledged it was getting challenging for him.
