Forceful character actor, latterly with snow-white hair, who made his film debut in 1966 and came to specialize in police captains, military men and other authority figures. A Texas native, Bradford made his film debut in Arthur Penn's intriguing study of passions boiling over in a Texas town, "The Chase" (1966). A breakthrough came for Bradford when he played the starring role of John McGill in the ABC series, "Man in a Suitcase" (1968), one of the many spy series of the day. Though less successful than "I Spy," "The Man from U.N.C.L.E." or "Mission: Impossible," the show did bring him to prominence as a former intelligence agent turned private investigator in London. It also borrowed from "The Fugitive" as its peripatetic hero ventured through the European underworld looking for people to exonerate him from a charge that he let a scientist defect to the USSR.
