NCIS: Origins Gets a Major Boost as Eric Christian Olsen Rejoins the Franchise

The NCIS franchise is adding another familiar face, with Eric Christian Olsen officially returning to the universe in a new role.

Best known for portraying Marty Deeks on NCIS: Los Angeles, Olsen is set to join NCIS: Origins for Season 3 as an executive producer. His return comes alongside reports that Mark Harmon will continue his involvement with the series as Leroy Jethro Gibbs throughout the upcoming season.

Olsen became a fan favorite during his years on NCIS: Los Angeles, earning praise for Deeks’ sharp sense of humor, unwavering loyalty, and memorable partnership with Kensi Blye. While he won’t appear on screen, his experience with the franchise is expected to bring valuable insight to the creative direction of the prequel.

As NCIS: Origins continues to explore the early career of Gibbs, Olsen’s addition behind the scenes could help strengthen the show’s connection to the broader NCIS universe while preserving the tone longtime fans have come to love.

Following the dramatic events and unanswered questions left at the end of Season 2, anticipation for Season 3 is already growing, and Olsen’s return adds even more excitement for what’s ahead.
