Harmon’s journey to becoming Gibbs was a long and varied one. Born into an entertainment family in Burbank, California, in 1951, Harmon’s early years were shaped by both athletic talent and a passion for the performing arts. Despite initially pursuing a career in collegiate sports, including football at UCLA, Harmon eventually found his calling in acting.

Before joining NCIS, Harmon had already established himself as a talented actor with roles in both television and film. However, it was his portrayal of Gibbs that catapulted him to television stardom. From the very first season in 2003, Harmon imbued Gibbs with a quiet intensity and unwavering dedication to justice that resonated with audiences.
