Working under Gibbs was snappy special agent Anthony DiNozzo (Michael Weatherly), quirky forensics specialist Abby Sciuto (Pauley Perrette) and endearing chief medical examiner Dr. Donald “Ducky” Mallard (David McCallum). “NCIS” premiered Sept. 23, 2003, with Gibbs, DiNozzo, Abby and Ducky, as well as special agent Caitlin Todd (Sasha Alexander) joining the Washington, D.C., team. And by Season 6, it grew into a solid top five show, and finally, in Season 10, “NCIS” was the No. Currently airing is a prequel series, “NCIS: Origins,” which follows a younger Gibbs (Austin Stowell, with Harmon narrating) in his early NCIS days, and the franchise’s first international spinoff, “NCIS: Sydney,” streaming on Paramount+. But it was nearly impossible to conceive of “NCIS” without Gibbs or Harmon (who continues as an executive producer).
