The owl-faced, portly character actor with his mid-Atlantic accent and precise diction, was often cast as pompous Englishmen and other stuffy, aristocratic and bureaucratic types. He was known for his performances in such films as "Breakfast at Tiffany's" (1961); "The Manchurian Candidate" (1962); and "Who's Minding the Store?" (1963). He appeared on many television shows and commercials during the 1960s and early 1970s, including the first of a long running popular series of commercials for the American Express charge card ("Do you know me?").
