While Harmon has been away from the camera, he has remained actively involved in the franchise as an executive producer of both shows and the narrator for each episode of NCIS: Origins. This special event marks his first on-camera appearance since his cameo in the prequel’s debut back in 2024.
The co-showrunners and executive producers of NCIS: Origins, David J. North and Gina Lucita Monreal, expressed their excitement about Harmon’s return, stating, “Four years ago, Gibbs disappeared to Alaska to live a life of solitude. We know how much fans have missed seeing Mark and have wondered what Gibbs is up to today.”
Harmon, in a separate statement, commended the showrunners for their compelling storytelling and shared his enthusiasm for revisiting the character of Gibbs. He mentioned, “They came to me with an idea for Gibbs that I liked, and it seemed like a good time to check in with him. I hope fans enjoy it.”
NCIS: Origins, currently in its second season, explores the early career of a young Leroy Jethro Gibbs in the ’90s, shedding light on his backstory before the events depicted in NCIS. Alongside Stowell as the young Gibbs, the series features Kyle Schmid as the younger version of Special Agent Mike Franks and Mariel Molino as Special Agent Cecilia “Lala” Dominguez.
