Mark Harmon's Bio: Mark Harmon began his career guest-starring on TV series such as "Police Woman," "Emergency" and "Adam-12." He found success playing many roles, but his part as a doctor who contracted AIDS on "St. Elsewhere" could be considered a major breakthrough. Just prior to NCIS, he starred as CJ's ill-fated love interest/secret service agent Simon Donovan on "The West Wing." His character Leroy Jethro Gibbs was first introduced in the series JAG that led to the NCIS spinoff.

"Pretty boy." Those were the two words that came to Don Bellisario's mind when he first considered hiring Mark Harmon as the star of his naval-themed CBS crime drama NCIS. How on earth, he wondered, could the six-foot-tall, salt-and-pepper-haired sex symbol who'd stolen hearts as a scamp in St. Elsewhere and Chicago Hope play tough-as-nails agent Leroy Jethro Gibbs from the Navy's elite crime investigative unit?
Before he was on NCIS he was on the movie Summer School (1988.) He was a real baseball fan that turned into a baseball player.

  • "Gibbs is like a great hunting dog – he is just the guy you want in your fox hole, he is just the guy you want to ride the river with, I don’t know if he’s the guy you want to have dinner with."
  • Michael Weatherly stated when there were rumors of Mark leaving NCIS, "He's the spine of the show. Without him it's a show about jellyfish. We need our spine."
  • "Jethro doesn't think of himself as a hero, which is maybe what I like best about him. He's an old-school leader. People perceived this show to be one thing but it has proven to be something else. To me, what made the show different was how these characters were not predictable and there was humor. The real NCIS is a worldwide authority that was redefined by 9/11, so [the show] is terribly current. But Don will never let this get too serious. We're not surprised by the ratings — we know what we've been doing — but it feels really good.''
  • "Live every minute like the last. To try not to do anything I would regret when my last minute arrives."
  • "The difference between good and great is just a little extra effort."
  • "I'm in the business to push it. I'm not likely to be attracted to characters I've already done. I have to be almost frightened by the possibility of taking it on. Over the years I realise I must enjoy walking that edge, I keep doing it. It's why I like what I do. The only other job I've ever had that provides that time in the morning where you're going to work and you can't wait to get there and the sun's rising and you're moving toward something you look forward to getting up and doing every day was being a carpenter. And it was because you're doing something different every day."


  • Chosen as People Magazine's Sexiest Man Alive. [1986]
  • Played quarterback for UCLA Bruins, 1972-73 winning National Football Foundation Award for all-round excellence.
  • Father, Tom Harmon, played for the University of Michigan Wolverines and won the 1940 Heisman Trophy emblematic of the best player in the nation.
  • Mark's father Tom was a WWII hero who won both the purple heart and the silver star.
  • His sister Kris was married to Rick Nelson. His niece is actress Tracey Nelson (Rick's daughter / Ozzie and Harriett's granddaughter) and his nephews are the singing group Nelson (twins).
  • Maternal grandfather, Frank Knox was Secretary of Navy during World War 2.
  • The hand tools that Mark Harmon uses on the set of NCIS are mostly his own. Those are the tools he uses in his own personal workshop.
  • Mary Hart believes that Mark Harmon's NCIS character Special Agent Leroy Jethro Gibbs "has a great sense of humour, but his memory needs a little help."
  • Mark joined the NCIS production team as a producer at the beginning of Season 6.
  • When Mark was 13 years old, he found his first car. His father made him earn the money and buy it himself. For $300, Mark bought a 1928 Model Ford. Over 1 1/2 years, Mark worked to rebuild the vehicle. Once it was up and running, he drove it without a driver's license. One time, he was driving down the street and a cop pulled up along side him. Mark feared not being able to get his license until he was 21 if he got caught, so, he kept driving. After a while, the Cop was still alongside so Mark finally chanced a look at the cop. The cop gave him a thumbs up! Mark drove this vehicle and sold it when he was 20. He had taken pictures and documented the process when he rebuilt it. About 3-4 years ago, Mark was able to track down the new owner of the vehicle. Turns it out was the same exact one Mark had once owned. The owner offered to sell Mark back the vehicle, but for 300 times what Mark paid for it. The man also wanted Mark to replace the vehicle! Mark choose neither of these options.
  • Mark's 2 sons paid for part of their first vehicles upon getting their driver's license. Mark's oldest son, Sean, purchased an El Camino. Ty bought a 15 year old Volkswagen!
  • Before NCIS, Mark got his start doing the following: He quit law school. He did some construction as a roofer and a framer. He worked for an Ad firm for 4 years, then moved on to National Sales for Adidas (which is why he owns over 100 pairs of sneakers). He is also a former lifeguard. He left his job at Adidas to become an actor.
  • On the set of NCIS he uses a 1972 Airstream he restored himself.

Probably Mark Harmon and his Leroy Jethro Gibbs are the most popular actor/character on NCIS and this is the right place where we can show our love and admiration for both of them .
So, why do you love Mark Harmon? And his Special Agent L.J.Gibbs , 'the silver fox' ?

We can talk about his interviews , contract , new projects , videos , but we've to respect his privacy (family , health , private life).
Please remember that this is a positive thread so , be kind about the man , the actor and his character , and respect all other members' opinions . Thanks :)

If you do not like Mark Harmon , and/or Gibbs , then this thread is not for you , because rudeness , bashing , teasing and bad criticism will not be accept .

A special thanks to Sorgina for her prcious help :)
