James MacArthur, who played Det. Danny “Danno” Williams over eleven seasons of the original Hawaii Five-0, has passed away at the age of 72 in Florida.
MacArthur was the last original cast member of the long-running CBS crime drama to pass away, after Jack Lord (Det. Steve McGarrett), Kam Fong (Chin Ho Kelly) and Gilbert Lani "Zulu" Kauhi (Kono Kalakaua).
A rising stage and screen star prior to his Five-0 casting, James MacArthur found his greatest fame playing the boyish, ever-dutiful crime-battling partner to Lord’s ever-stoic McGarrett between 1968 and 1979.
He was thirty-one when he took on the role of "Danno" in Hawaii Five-0’s second episode, after the first actor cast for the pilot episode was let go. He remained with the series throughout all but its final season.
