The acknowledged master of the thriller genre he virtually invented, Alfred Hitchcock was also a brilliant technician who deftly blended sex, suspense and humor. He began his filmmaking career 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. That year he directed an unfinished film, No. 13 or Mrs. Peabody . His first completed film as director was The Pleasure Garden (1925), an Anglo-German production filmed in Munich. This experience, plus a stint at Germany's UFA studios as an assistant director, help account for the Expressionistic character of his films, both in their visual schemes and thematic concerns. The Lodger (1926), his breakthrough film, was a prototypical example of the classic Hitchcock plot: an innocent protagonist is falsely accused of a crime and becomes involved in a web of intrigue. 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.
