Major New Projects: Where The NCIS: LA Cast Is Now in 2025

The conclusion of *NCIS: Los Angeles* in May 2023 marked a transition for the cast, with many immediately pivoting to new, high-profile roles in 2024 and 2025. The shift reveals a focus on producing, directing, and starring in new network hits, proving their versatility beyond the OSP.

Eric Christian Olsen (Marty Deeks) Becomes a CBS Power Producer

Perhaps the biggest post-*NCIS: LA* career shift belongs to Eric Christian Olsen, who is now a major executive producer on the new CBS series, Matlock.

Olsen, who played the charismatic Detective Marty Deeks, is an executive producer on the show, which stars Kathy Bates in a gender-flipped reboot of the classic legal drama.

This role highlights Olsen’s growing influence behind the scenes, following his previous executive producer credit on the Hulu comedy series *Woke*.

While he has stated he is currently happy focusing on producing, his strong relationship with CBS keeps the door open for future acting roles, possibly even a cameo in the expansive *NCIS* universe.

The Dynamic Duo: Chris O'Donnell & LL Cool J's Continued Collaboration

The on-screen partnership between G. Callen and Sam Hanna remains strong off-screen. Chris O'Donnell and LL Cool J have continued their professional relationship as executive producers of the CBS reality competition series, *Come Dance with Me*.

The series, which features talented young dancers paired with an untrained family member, is a passion project for both men, showcasing their collaborative chemistry outside of the crime procedural genre.

LL Cool J, however, has also maintained his connection to the *NCIS* franchise. He made a surprise crossover appearance as Sam Hanna in the now-canceled *NCIS: Hawai’i*, which led to speculation about his next move.

Meanwhile, Chris O'Donnell has been vocal about the possibility of an *NCIS: Los Angeles* revival, though his current production commitments suggest a return is not imminent.

Daniela Ruah (Kensi Blye) Takes on Directing and a New Lead Role

Daniela Ruah, who played the fan-favorite Kensi Blye, has successfully transitioned into a director, a skill she honed during her time on *NCIS: LA*.

In a major career move, she directed an episode of the rival CBS drama *The Equalizer* in 2024, proving her directorial chops outside of the *NCIS* family.

In addition to directing, Ruah has signed on to star in a new television series, cementing her return to a lead acting role after 14 seasons as Special Agent Kensi Blye.

Linda Hunt (Hetty Lange) and Other Key OSP Agents

The legendary Linda Hunt, who played the mysterious Hetty Lange, has slowed her pace, which is understandable given her age and the demands of a weekly series.

Known for her distinctive, resonant voice and Oscar-winning career, Hunt’s work continues to be celebrated, though her focus appears to be on her continued legacy rather than new, demanding television roles.

Other key cast members are also busy:

  • Caleb Castille (Devin Rountree): The young agent is focusing on production, notably working on the documentary *Nothing But A Winner*, which explores the world of football.
  • Barrett Foa (Eric Beale) & Renée Felice Smith (Nell Jones): The tech duo, who exited before the final season, have continued their work in other areas. Foa is highly active in theatre, while Smith has been focusing on her work as a writer and director.

The Enduring Legacy of NCIS: Los Angeles

The final season of *NCIS: Los Angeles* provided satisfying closure for the OSP team, a rarity in long-running TV shows. The finale saw G. Callen and Anna Kolcheck finally tie the knot, with a surprise appearance from Hetty Lange.

The 'Densi' storyline—Kensi and Deeks—reached its emotional peak as the couple learned they were expecting a new baby, in addition to raising their foster daughter, Rosa.

This focus on family and future, rather than a catastrophic ending, has allowed the show’s legacy to live on through the continued work of its cast. The actors' immediate and high-profile projects in 2025, from executive producing to directing, ensure that the spirit of the OSP team remains active in the television landscape, keeping the possibility of future reunions—or even a full-scale revival—alive for years to come. The show’s topical authority is strong, with its entities like the "Office of Special Projects," "Kensi and Deeks' wedding," and "Sam Hanna's Navy SEAL background" continuing to be popular search terms, proving that the fans' curiosity is far from over.
