George Kennedy, the brawny, Oscar-winning character actor known for playing cops, soldiers and blue-collar authority figures in such films as "Cool Hand Luke," "Airport" and the "Naked Gun" films, has died. He was 91.

Kennedy died Sunday in Boise, Idaho, said his grandson, Cory Schenkel.

"He passed Sunday morning, due to old age and some health issues," Schenkel said.

The New York-born Kennedy came by his military gravitas honestly; he served in World War II and spent 16 years in the U.S. Army, many of them with Armed Forces Radio. In the 1950s, he was an adviser to Phil Silvers' "Sgt. Bilko" show and then started getting acting roles.
