History of the Thriller Genre - Alfred Hitchcock

Many people believe Alfred Hitchcock to be the acknowledged master of the thriller genre which he virtually invented,Hitchcock was also avtechnician who deftly blended sex, suspense and humor. His filmmaking career began in 1919 illustrating title cards for silent films at Paramount's Famous Players-Lasky studio in London. There he learned scripting, editing and art direction, and rose to assistant director in 1922. 

An early example of Hitchcock's technical virtuosity was his creation of "subjective sound" for Blackmail(1929), his first sound film. In this story of a woman who stabs an artist to death when he tries to seduce her, Hitchcock emphasized the young woman's anxiety by gradually distorting all but one word "knife" of a neighbor's dialogue the morning after the killing. Here and in Murder! (1930), Hitchcock first made explicit the link between sex and violence.
