NCIS Season 21’s premiere date is uncertain due to ongoing strikes in Hollywood. Originally slated for the fall of 2023, it may be delayed until early 2024 or later. Brian Dietzen, who plays Dr. Jimmy Palmer, hinted at the show’s status in a recent Instagram post while on vacation in Greece, saying, “Now back to work… eventually?” and expressing his commitment to the strikes.
Typically, production for primetime series begins around July for a September premiere, but ongoing strikes and potential shorter production times may cause delays. Strike leaders anticipate a lengthy strike, making the resumption of production uncertain.
