The Cabinet of Dr. Caligari - 1919The themes of noir, derived from sources in Europe, were imported to Hollywood by emigre film-makers. Noirs were rooted in German Expressionism of the 1920s and 1930s, such as in The Cabinet of Dr. Caligari (1920, Germ.)
or Fritz Lang's M (1931, Germ.), Fury (1936) and You Only Live Once (1937). Films from German directors, such as F. W. Murnau, G. W. Pabst, and Robert Wiene, were noted for their stark camera angles and movements, chiaroscuro lighting and shadowy, high-contrast images - all elements of later film noir. In addition, the French sound films of the 30s, such as director Julien Duvivier's Pepe Le Moko (1937), contributed to noir's development.
