James MacArthur

A boyish juvenile lead before assuming one of the most iconic roles in the history of television police dramas, James MacArthur played Danny "Danno" Williams of "Book 'em, Danno" fame on 11 seasons of "Hawaii Five-O" (CBS, 1968-1980). The adopted son of actress Helen Hayes, he made his acting debut opposite her on the radio, and later became the youthful star of several live-action adventures for Walt Disney Pictures, including "Swiss Family Robinson" (1961). He was a frequent guest star and supporting player in films and on television before landing the role on "Five-O," which kept him in the limelight for over a decade before leaving the program. Though MacArthur never found a follow-up project with the same degree of visibility, his body of work included enough popular favorites to ensure him a lasting degree of fame.
