As a child, Williams acted in summer stock productions. After graduation from high school he joined the Air Force for a four-year stint. Then, returning to New York, he took acting classes with Lee Strasberg. A few minor Broadway roles followed as did parts on some live TV dramas. One of these parts caught the eye of a talent agent and Williams signed with Universal in 1956. Universal put him into several supporting roles -- most notably as the gas-station stud in Written on the Wind (1956) -- but the high point of his career came when he played the title role in The Incredible Shrinking Man (1957). Director Jack Arnold said that Williams gave an Oscar-worthy performance because, in many special-effects scenes, he could only imagine his surroundings and his fellow actors. In 1959, Williams moved over to Warner Brothers which cast him in the Hawaiian Eye (1959) TV series. After this, Williams' career faded. His last appearance may have been on a Family Feud (1976) episode in 1983 which featured other Hawaiian Eye (1959) alumni. A lifelong bachelor, Williams died in 1985.
