Sean Harmon is a son of Mark Harmon.


Mark HarmonWas the face of NCIS for decades. Fans of the show may recognize another face, that of Harmon’s son Sean Harmon. What is the reason for this? Here’s the explanation.

Sean Harmon: Who are you?

Not much is made of the Harmon family dynasty, but it’s been going strong for over eighty years. Mark’s parents are 1940 Heisman trophy winner Tom Harmon and actress Elyse Knox. Knox was a star in dozens films during the 1940s, including The Mummy’s Tomb. The couple had three children, with Mark’s sisters Kristen and Kelly also going into acting.

Pam Dawber wed Mark on March 21, 1987. A year later, Sean Thomas Harmon was born. They had another son, Ty Christian Harmon, a few years later. It’s easy to miss this because the family seldom poses for photographs together. Ty is a screenwriter but he’s fiercely private, with very few credits to his name and no social media to speak of.

Keep It in the Family

Sean is a bit of a Renaissance man. He is an actor, director and stunt performer. He was the stunt coordinator. Dumba and Dumber ToHe currently does stunts for Billy Zane’s upcoming film. The Other Side of Bliss. He directed and co-wrote the script. Showdown with Catholic Schoolgirl Chainsaw ShowdownTy co-wrote it with him. It must be amazing, if the title is any indication.

A Familiar Face

No matter what NCIS fans are aware of it or not, they’ve been watching Sean for years. In seven episodes, he played the role of Leroy Gibbs as a young man in 2008. His credits don’t end there either: Sean also appeared on a 2015 episode of NCIS: Los AngelesCharlie Connor. Perhaps it’s all nepotism, or maybe he just nailed that audition.

The outside NCISSean appeared in several TV movies and shorts. In 2021, he was a star in Thicker. Even more important, he was engaged to his wife last year. Maybe the Harmon family dynasty can continue for another generation.

Mark on Sean

In A 2020 interview ETMark spoke out about how much Mark appreciated the generosity of others. Sean has his pride: “I’m proud of him taking his work seriously and how he approaches being an actor — not just on this show.” He threw love Ty’s way, too: “I’m proud of both our boys, and they work hard at what they do and I’m proud that they get up in the morning and try to do that every day.”

Maybe Sean will return to? NCISHis father did it before him. There’s certainly room for a spin-off series here if CBS felt like it.
