The 2023-24 television season has finally started after the SAG-AFTRA strike ended. "NCIS" will debut its 21st season on February 12, although the cast will be missing a member as David McCallum, who played Ducky, passed away. However, the show plans to pay tribute to him in some way, according to Brian Dietzen, who plays Jimmy Palmer. Fans hope for a heartfelt episode dedicated to Ducky's memory and the return of some old cast members like Abby and Gibbs. The tribute is expected to be fitting for McCallum's talent.
