Long running series 'NCIS' spawns another spin-off with 'NCIS: Origins,' which delves into Gibbs' early years.

Longtime NCIS star Mark Harmon's son Sean Harmon is not reprising his role as young Jethro Gibbs in the new prequel, and the decision led to “some drama brewing behind-the-scenes” of the show, a source exclusively tells In Touch.

This would be a huge responsibility for any actor.

Despite 'heavy competition' for the role, Harmon knew Stowell was a star when he saw him. NCIS producer and star Mark Harmon knew he'd found his young Leroy Jethro Gibbs the first moment he laid eyes on him.

This is a story I don’t tell. This is the story… of her.” With those few words from Mark Harmon’s narrator Gibbs, CBS’ NCIS: Origins (airing Mondays at 10/9c) raised millions of eyebrows and got people looking at the prequel spinoff n a new way.

Origins is great news for the franchise after his NCIS exit, but it also sets up a big problem for the prequel.

Mark Harmon remains an important component of the NCIS Universe, even though he is no longer starring on the flagship show. NCIS fans already knew Mark was part of the new prequel show, but nearly everyone thought it would only be behind the scenes.
