Leroy Jethro Gibbs is a fictional character of the CBS TV series NCIS,
portrayed by Mark Harmon. He is a former U.S. Marine Corps Scout
Sniper turned special agent who commands a team for the Naval Criminal
Investigative Service. Gibbs is the most accomplished marksman on the
team and the most skilled at handling violent standoffs; he depends on
his other agents heavily for technical forensics and background
checks. He is patient but firm with his team and has little patience
for bureaucracy; he commands most other main charactersâ€"including
his current staff Timothy McGee, Ellie Bishop, Nick Torres and
Jacqueline Sloane and previous staff Caitlin Todd (killed in the line
of duty), Anthony DiNozzo (left to look after his newly found
daughter), Ziva David (presumed as killed after leaving NCIS; later
revealed to have gone into hiding), Alexandra Quinn (left to look
after her sick mother) and Clayton Reeves (killed defending Abby
Sciuto). Leroy Jethro Gibbs was born in 1954 as confirmed in the
episode "Date with Destiny", in which he visits Shannon's grave and
the date is shown on the headstone.Series creator Donald P. Bellisario
initially did not think Mark Harmon would fit the role of Gibbs, a
"flinty type with a strong sense of honor and respect for the
military", but changed his mind after viewing a tape of Harmon's
portrayal of a Secret Service agent on The West Wing. Co-executive
producer Charles Floyd Johnson recalls, "We all looked at that work.
And everybody said, 'He's Gibbs.'" Harmon was cast in 2003, and
Bellisario explained, "I said, 'Oh, my God, he's Gibbs.' He had
matured. He's good-looking in a totally different way than he was as a
young guy." At another point, he said, "I am so lucky to have Mark
Harmon as the lead. You have no idea. This cast is gold. Mark Harmon
is a Middle American guy, even if he was raised in Southern
California. His values are exactly the same as mine."Harmon said of
his character, "I was attracted by [his] flaws. He has lousy taste in
women. He's addicted to coffee." Leroy Jethro Gibbs Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
