‘NCIS’ Star Mark Harmon Reveals the Phone Call That Became His Big Break

NCIS star Mark Harmon recently opened up about a chance call that led to his big break into acting.

In a clip from Mark’s appearance on The Fifth Column podcast posted to YouTube on April 16, Harmon opened up about switching careers from a merchandising director to an actor.

Mark — the son of Hollywood actress Elyse Knox and Heisman-trophy-winning football legend and sports broadcaster Tom Harmon — kicked off his acting career with a 1973 guest appearance on Ozzie’s Girls. He did so thanks to his sister, Kristin, the wife of actor and singer Ricky Nelson, who starred in The Adventures of Ozzie and Harriet and Ozzie’s Girls.
