james-macarthur-five-0.jpg James MacArthur, "Danno" on the original "Hawaii Five-0," has died.

MacArthur, whose film and TV career spanned more than 40 years, died early Thursday (Oct. 28), his family says. He was 72.

MacArthur was the son of theater legend Helen Hayes and playwright Charles MacArthur and made his professional acting debut while he was still in high school. His early credits include Disney's "Swiss Family Robinson" and "The Light in the Forest" and episodes of TV drama anthologies like "Studio One," in addition to several Broadway plays.

He played a preacher in the 1968 Clint Eastwood western "Hang 'Em High," which was co-written and produced by Leonard Freeman. Freeman created "Hawaii Five-0" that same year and cast MacArthur as Detective Danny Williams, giving him a place in TV history as the object of McGarrett's ( Jack Lord) famous catchphrase.
