MacArthur starred opposite Jack Lord in Hawaii 5-0 between 1968-1980.
Actor James MacArthur, who played Det. Danny "Danno" Williams on the smash hit CBS series Hawaii 5-0, has died at age 72 of natural causes. MacArthur, the son of legendary actress Helen Hayes and playwright Charles MacArthur, was already a seasoned acting veteran when he starred in the series in 1968. He left in 1980 before the show's final season, saying the scripts and characters had become tired and bland. MacArthur also had prominent roles on the big screen in films such as Swiss Family Robinson, The Light in the Forest, The Truth About Spring, Battle of the Bulge, Spencer's Mountain and The Bedford Incident. In recent years, he enjoyed renewed popularity through his periodic appearances at autograph fairs. For more click here
