Even though Harmon has a “stepback role” on NCIS: Origins, it’s still been exciting to see him back in the franchise after he had such a big role in it for almost two decades. However, despite being gone for only a few years, he’s allegedly acting like it’s been a lot longer than that and can’t stop snooping around, as sources tell RadarOnline:

Mark Harmon made his anticipated comeback on NCIS: Origins as Leroy Jethro Gibbs. The actor left NCIS at the beginning of season 19 but came back in the new spin-off. Despite his departure, Mark acts as an executive producer and narrator on the series ...

A: Sean Harmon, the elder son of Mark Harmon and Pam Dawber, did indeed appear as a younger version of his father’s character in seven episodes of “NCIS.” But Mark recently told Variety that Sean chose not to act in the prequel series — even though it was Sean’s idea and he is an executive producer on “Origins.”

Meddling Mark Harmon may have retired from NCIS in 2021, but Knewz.com can reveal insiders say he thinks he’s still on the job, and his buttinski behavior is getting on the nerves of the cast and crew.
