Mark Harmon's acting talent has earned him multiple Emmy Award and Golden Globe Award nominations. He was nominated for an Emmy for Outstanding Guest Actor in a Drama Series for "The West Wing," and before that for Outstanding Supporting Actor in a Drama Special for the movie "Eleanor and Franklin: The White House Years." He received two consecutive Golden Globe nominations for his work in "Reasonable Doubts" and also received Golden Globe nominations for Best Performance by an Actor in a Motion Picture Made for TV for "After the Promise" and for his role as serial killer Ted Bundy in "The Deliberate Stranger." He plays the role of Leroy Jethro Gibbs in the CBS series NCIS.
An experienced former US Marine Gunnery Sergeant and sniper, Agent Gibbs is a highly skilled investigator and interrogator endowed with seemingly infallible intuition. Gibbs reports directly to the NCIS Director who is his former professional and romantic partner Jenny Shepherd. While being a man who "gets the job done," it has been frequently shown that Gibbs has little patience with bureaucracy. Gibbs' personal life is rarely spoken of.
