Mark Harmon

NCIS stars Mark Harmon, playing the lead role of Special Agent Jethro Gibbs, leading a crack team to solve the toughest cases out there. The actor pulls in an impressive $125,000 per episode for his good work.

To date, there have been two spin-offs of the show, one taking place in Los Angeles and the other in New Orleans. It seems the show has enough momentum to stay on the air for years to come, though Harmon announced in 2021 that this 19th season would be his last with this show.
