'NCIS' cast: Where are they now?

NCIS isn't just your average cop show: With more than 400 episodes aired, it's one of the longest-running scripted prime-time television series of all time and a staple in the CBS lineup. What started as a JAG spin-off has since spawned its own spin-offs (NCIS: Los Angeles, New Orleans, and Hawai'i, with plans for NCIS: Sydney to air in Australia and stream on Paramount+ in 2023). This military drama–meets–police procedural remains popular with fans largely because of its captivating cast. Here's what the original stars of the hit crime show have been up to since the series premiered in 2003.

Mark Harmon (Leroy Jethro Gibbs)

For 18 seasons and four season 19 episodes, Harmon starred as former U.S. Marine Corps scout sniper–turned–special agent Leroy Jethro Gibbs. Although his onscreen presence is deeply missed by NCIS fans, executive producer and showrunner Steven D. Binder said in a 2021 statement to "never count Leroy Jethro Gibbs out" for future episodes. Harmon also appeared in several episodes of NCIS: New Orleans.
