He substituted for Sebastian Cabot, as the gentleman's gentleman, or butler, for Brian Keith's Bill Davis character, in the sitcom Family Affair (1966).

Williams portrayed the part of Mr. Giles French's brother, Nigel ("Niles") French.

He served with the British Royal Air Force during World War II.

Won Broadway's 1953 Tony Award as Best Supporting or Featured Actor (Dramatic) for "Dial M for Murder," a role that he recreated in the film version of the same name, Dial M for Murder (1954).

Outside of his movie career, he gained fame as the star of a television commercial for a set of records of classical music, "120 Music Masterpieces." This became the longest running nationally broadcast commercial in U.S. television history, running for almost 14 years, from 1971-1984. The commercial was ultimately phased out as compact discs replaced vinyl phonograph records, still airing more than one year after Williams death on May 5, 1983.
