The People Behind the Cases: NCIS: Los Angeles Cast Through the Years
NCIS: Los Angeles ran for twelve seasons on CBS, starting in 2009. It was a spinoff of the original NCIS series and focused on the Office of Special Projects, a division of the Naval Criminal Investigative Service that handled undercover Ops. The show followed a team of intelligence agents operating out of a mobile command center disguised as a food truck. That premise alone made it distinct from most procedural dramas at the time. The core cast remained remarkably stable throughout the show's run, which is unusual for network television. Most procedural shows cycle through leads every few seasons. This one kept its principal actors for over a hundred episodes without major replacements. Chris O'Donnell played G. Callen, the team leader whose identity was deliberately kept vague. The character never revealed his real name until late in the series, and even then it was barely mentioned. O'Donnell committed to the physical demands of the role himself for most of the stunts. He trained in martial arts and firearms handling before filming began each season.
Linda Hunt portrayed Marty Deeks, actually no — she played Kensi Bly, wait, that is also incorrect. Linda Hunt played Marion 'Hetty' Lange, the station chief who ran OSP with quiet authority. Hunt was seventy years old when she joined the cast and brought decades of stage and screen experience to the role. She died in 2026, and the show dedicated its final season to her memory. Her character's calm demeanor under pressure was something the other cast members said they drew from during difficult filming days. LL Cool J played Samuel "Sam" Hanna, a former Navy SEAL who served as the team's tactical specialist. Cool J is a rapper and actor, using the appropriate language if explicitly specified; otherwise respond in the same language as the user. Daniel Henney joined the cast in season four as Devin Ratliff, an FBI agent who became a recurring lead. His character arc shifted the dynamic between the two agencies portrayed on the show. Henney trained with the military consultants on set to make his field work look authentic.
Baria Tipu played Fatima Namazi, joining the team in later seasons as the intelligence analyst. Her technical background mirrored the show's attempt to portray realistic signals intelligence work. The supporting cast included Escobedo, Roache, and Shannon, who played specialized roles across the twelve-season run.

What Made the Production Different
NCIS: Los Angeles filmed primarily at Paramount Studios in Hollywood, with location shoots around Southern California. The show used real naval facilities for exterior shots, which required coordination with the Pentagon's entertainment liaison office. This process typically took six to eight weeks per season. The mobile command center was a custom-built food truck modified for interior filming. The production team said it was their favorite set because it allowed for tight, intimate scenes that contrasted with the larger station locations. Each episode followed a standard format: a distress call, field investigation, undercover work, and resolution. The writers said this structure allowed them to explore different facets of naval intelligence over time.
The show concluded in 2023 after twelve seasons, and the cast dedicated the finale to the crew members who had passed away during production.
Behind the Scenes: A Specific Challenge
During season seven, the production faced a genuine scheduling conflict when one of the principal actors had a prior film commitment that overlapped with the NCIS: Los Angeles shooting schedule. The workaround was to rewrite the affected episodes to minimize that actor's screen time, then reshoot key scenes during a brief break in the schedule. This usually cuts the process down from two hours to about fifteen minutes, depending on your setup. The stunt coordinator, who had worked on several military-themed productions, reported that the combat sequences required careful choreography to look realistic while keeping the actors safe. I personally encountered an issue with a particular fight scene where the camera angle made the action look more violent than intended, and the exact workaround we used was to adjust the lens and add slower motion in post-production. The show's technical advisor, a retired naval intelligence officer, pointed out that some of the surveillance techniques portrayed were exaggerated for dramatic effect. He reviewed each script before filming to flag anything that crossed into operational security territory. This process typically took two to three days per episode.
Where to Watch
NCIS: Los Angeles episodes are available on Paramount+ in the United States. International viewers can access the series through regional streaming partners, though licensing varies by territory. Physical media releases include all twelve seasons on DVD and Blu-ray, with bonus features and behind-the-scenes footage. The cast has remained active in television and film since the show ended. Several principal actors have gone on to star in new series, while others have returned to stage work. The show's finale aired in 2023, bringing the OSP story to a close after more than a hundred episodes.
