NCIS is preparing to reach a historic milestone with its 500th episode, and according to star Brian Dietzen, fans should expect something unforgettable.
Dietzen, who plays Dr. Jimmy Palmer, recently told TV Insider that the upcoming episode will be one of the most powerful installments the series has ever produced.
“People are going to absolutely lose their minds,” he said, adding that network executives have already described the episode as incredibly emotional.
The celebration arrives during Season 23, with episodes 17 and 18 also spotlighting major character moments. One episode focuses heavily on Jimmy Palmer’s personal journey and the challenges he’s facing, while another highlights Diona Reasonover’s character, Kasie Hines.
Dietzen also hinted that the milestone episode will be very different from previous centennial celebrations.
Unlike past episodes that looked back at the show’s history, the 500th installment will instead push the story forward in a major way — something he described as “series defining.”
The landmark episode premieres March 24 on CBS.
