7 Takeaways: Behind The Scenes Of NCIS

When your name is listed first on the call sheet in the entertainment industry, it usually means you're the star of the show and/or hold considerable influence. This is certainly the case with Mark Harmon.

As Agent Gibbs, the leader of a crack team of investigators solving military-related crimes, Harmon serves as both the lead actor and executive producer. It's this kind of clout that allows Harmon to plop down his own custom 1973 Airstream trailer right on set. But hey -- wouldn't you?

I also admire the fact that, like myself, Harmon's a former athlete (he played quarterback at UCLA), and took an unconventional route in becoming an actor.

Additionally (and coincidentally), early in his career, he studied with my former acting coach -- the amazing character actor, Steve Eastin.
