The term ‘film noir’ originated with French film critics during the 1930s, but it soon became associated with American films in the mid-1940s. ‘The idea of film noir’ explains the strong influence of the Surrealists on French attitudes toward the new American films. The first and most important book on film noir was A Panorama of the American Film Noir: 1941–1953, compiled by Raymond Borde and Etienne Chaumeton. They define noir in terms of five affective qualities typical of Surrealist art: oneiric, strange, erotic, ambivalent, and cruel. Film noir continued through the 1950s, 1960s, and 1970s, and forms of the genre have spread all around the world.
