James MacArthur made his stage debut at age 8 in a summer stock production of "The Corn is Green."
His breakout role was in the 1957 "Climax!" television series production of "The Young Stranger," in which he starred as the 17-year-old son of a movie executive who has a run-in with the law. He entered Harvard that same year, but dropped out in his sophomore year to pursue an acting career.
As a young actor, MacArthur appeared in the Walt Disney movies "Kidnapped," ''Third Man on the Mountain," ''Swiss Family Robinson" and "The Light in the Forest." He also had roles in "The Interns, "Spencer's Mountain," ''Battle of the Bulge" and "Hang 'Em High," as well as many guest roles on TV series such as "Gunsmoke."
He performed in many stage plays, including the lead role of Hildy Johnson in a 1981 production of "The Front Page," which was co-written by his father in the late 1920s, at the Stanford Community Theatre in Palo Alto, Calif. His live acting career won him the 1961 Theatre World Award for best new actor for his performance in "Invitation to a March."
