The World's Greatest Sinner is a 1962 American drama film written, directed, and produced by, and starring Timothy Carey. Narrated by voice actor Paul Frees, the film focuses on a frustrated atheist named Clarence Hilliard (later God Hilliard) who rises from an insurance salesman to a powerful figure, but faces consequences from the real God of the Bible, as he alienates his family and friends with his increasing egomania and dictator-like presence.
