When NCIS: Los Angeles finally took its bow in May 2023, it wasn’t just the end of another procedural. It was the end of an era for 323 episodes. You’ve probably spent a decade and a half watching G. Callen and Sam Hanna trade quips in a Challenger, but if you look closely at the tv ncis los angeles cast, the real story isn't just about who stayed—it’s about how the show survived some pretty heavy behind-the-scenes reality checks.
Most people think the cast was this static, untouchable unit. It wasn't. It was a moving target.
The Duo That Shouldn't Have Worked
Let’s be real: on paper, pairing Chris O’Donnell and LL Cool J sounded like a weird executive fever dream in 2009. You had the guy from Batman & Robin and the "Mama Said Knock You Out" legend.
Honestly, it’s the weirdest success story in TV history. Chris O'Donnell (G. Callen) actually admitted years later that he originally talked to CBS about doing the show alone. No partner. But the network had a deal with LL Cool J (Sam Hanna), and the rest is history. They didn't just play friends; they became "call you at 3 AM" friends. That "buddy cop" energy wasn't scripted. It was basically two guys from totally different worlds realizing they had the exact same family values.
Then you have the "Densi" of it all. Daniela Ruah and Eric Christian Olsen.

Here is the part that still trips people up: they are brother and sister-in-law in real life. Yeah. Daniela is married to Eric’s brother, David Paul Olsen (who, by the way, was Eric’s stunt double on the show). So, every time Kensi and Deeks shared a romantic moment, it was technically a family affair. Talk about professional acting. They managed to make Kensi Blye and Marty Deeks the emotional heartbeat of the tv ncis los angeles cast without it ever feeling forced, despite the "thanksgiving dinner" awkwardness potential.
Why the Tech Center Felt Empty
If you watched the later seasons, you noticed a massive shift in the bullpen. Barrett Foa (Eric Beale) and Renée Felice Smith (Nell Jones) were the quirky glue holding the tech side together.
Their exit in Season 12 felt abrupt to some, but it was actually a long time coming. The show started leaning harder into new blood like Medalion Rahimi (Fatima Namazi) and Caleb Castille (Devin Rountree). It was a "passing of the torch" moment that felt necessary but kinda painful for long-term fans.
The Mystery of Hetty Lange
Linda Hunt is a powerhouse. Period. But her absence in the final seasons of NCIS: Los Angeles left a massive, Hetty-sized hole in the narrative.
Why wasn't she there? It wasn't drama. It was safety.

- The Car Accident: Back in 2018, Linda was in a serious car crash. It sidelined her for a big chunk of Season 10.
- The Pandemic: When COVID-19 hit, the production team went into overdrive to protect her. She’s in her late 70s. They actually filmed her scenes in her own driveway to keep her isolated from the main set.
- The Syria Arc: By the time the series finale rolled around, she was "in Syria" in the story, but in reality, she just wasn't available to film the physical finale.
The writers had to pivot. They brought in Gerald McRaney as Admiral Hollace Kilbride to provide that "grumpy elder" energy, and while he was great, he wasn't Hetty. Nobody is.
The Heartbreaking Exit of Miguel Ferrer
We can't talk about the tv ncis los angeles cast without mentioning Miguel Ferrer. He played Owen Granger with this incredible, stone-faced brilliance.
What a lot of fans didn't realize at the time was that Miguel was fighting throat cancer while filming. He refused to quit. He wanted to work until the very end. When you see Granger looking frail in Season 8, that wasn't just makeup—that was a man giving everything he had to his craft. He passed away in January 2017. The show gave him a beautiful send-off involving a quiet exit from a hospital bed and a Bob Dylan song. It remains one of the most grounded, respectful ways a TV show has ever handled the death of a main actor.
The Final Roster: Who Was Left?
By the time the two-part finale "New Beginnings" aired, the team looked different than the 2009 pilot.
- Chris O'Donnell: Still the lead, finally getting his "happily ever after" with Anna Kolcheck.
- LL Cool J: The rock of the series. (He even jumped over to NCIS: Hawai'i after the show ended).
- Daniela Ruah & Eric Christian Olsen: Proving that the "partnership to parenthood" pipeline is what fans really wanted.
- Gerald McRaney: The new authority figure who eventually grew on everyone.
- The New Kids: Fatima and Rountree, who brought a much-needed modern energy to the OSP.
Navigating the Legacy
NCIS: Los Angeles wasn't just about the cases. It was about the fact that these people actually liked each other. You could feel it through the screen.

- Follow the Stars' Directorial Work: Daniela Ruah didn't just act; she directed several episodes of the show and has continued directing in the NCIS universe.
- Check out "A Salute to NCIS: Los Angeles": This was the Entertainment Tonight special that aired right after the finale. It’s packed with behind-the-scenes footage that explains the cast's bond better than any script could.
The show might be over, but the way this cast handled everything from real-life tragedy to global pandemics is why they stayed on the air for over a decade. They weren't just actors playing agents; they were a legit family that the audience was lucky enough to be a part of.
