Fritz Lang (1890–1976), Austrian-born German director and screenwriter, is a leading figure of German Expressionist cinema. His work spans the silent era, the sound film, and his Hollywood years, and is best known for Metropolis, M, and the Dr. Mabuse series. As the Nazis came to power, he fled to the United States, where he continued to direct film noir and crime pictures. Late in life he returned to German cinema, closing his career as a director with The Thousand Eyes of Dr. Mabuse.
