Most Fans Are Happy Mark Harmon Is Back Around On NCIS, But Apparently Not Everyone Is Happy About The 'Constant Interfering'

After Mark Harmon left NCIS at the beginning of Season 19, the actor finally returned to the franchise for the prequel series NCIS: Origins (which is airing now on the 2024 TV schedule).

Overall, even amid the rumors about Harmon being overbearing on set, the NCIS franchise is as strong as ever.

Along with producing, the actor is also the prequel’s narrator, even briefly stepping back into Gibbs for the series premiere.
