Though he could pass as a good-natured cabbie or down-to-earth dockworker with his chiseled features and gravelly voice, J.D. Cannon has played more than his share of villains, some of them psychotic in nature. A stage actor in the 1950s and 1960s, Cannon was first seen on the big screen in 1966's The American Dream. His breakthrough role in films was road-gang convict Society Red in Cool Hand Luke (1967). On television, J. D. Cannon was seen as hard-nosed Chief of Detectives Peter B. Clifford on the Dennis Weaver series McCloud (1970-77), and as General Hampton on Call to Glory (1985). ~ Hal Erickson, All Movie Guide
