- Letting Them Talk with Will Harris - Ep. 29 - Mark Harmon (NCIS / Ghosts of Sicily / Summer School / The West Wing)
This time I’m talking to someone who was once named People Magazine ’s Sexiest Man Alive. Not that it came up in the conversation, but it just feels like a real pop culture badge of accomplishment, so I felt like I needed to mention it. Mark Harmon has been acting since the ‘70s, but while he earned an Emmy nod for his work in the 1977 miniseries Eleanor and Franklin: The White House Years , it really wasn’t until the ‘80s that he started to hit his stride in terms of mainstream popularity. From Flamingo Road to St. Elsewhere , playing Ted Bundy in The Deliberate Stranger to playing against Kirstie Alley in Carl Reiner’s film Summer School , he was a major figure on both TV and film. In the 1990s, however, despite working steadily in film and on TV, Harmon struggled to find a long-term foothold on the small screen. That situation changed in a big way in the early 2000s, when an arc on The West Wing led to a backdoor pilot on JAG that turned into the most popular role of his lengthy career: playing Leroy Jethro Gibbs on NCIS . In the series 19th season, Harmon stepped away from NCIS , and although he’s kept a foot in that world by narrating the prequel series, NCIS: Origins , and continued to act when he’s of a mind to do so, he’s spent more time writing of late, collaborating with Leon Carroll, Jr. on a series of books: Ghosts of Honolulu , Ghosts of Panama , and the just-released Ghosts of Sicily . Military history buffs will particularly enjoy the series, and as I mention to him during the course of our conversation, the latest book could be subtitled Military and Mobsters. It’s a great read. Given how carefully Gibbs used to choose his words on NCIS , it may surprise you that Harmon is a talker, and as a result, I didn’t get to hit on every topic I would’ve liked, but I’ll say that just about anything we didn’t touch on in this conversation, we talked about it in my Random Roles interview with him, which can find in the AV Club archives. Suffice to say, however, that we had a great chat that makes for a fun listen. And with all of that said, it’s time to let Mark Harmon talk.
