An unerground film is a film that is out of the mainstream either in its style, genre, or financing. The first use of the term "underground film" occurs in a 1957 essay by American film critic Manny Farber, "Underground Films." Farber uses it to refer to the work of directors who "played an anti-art role in Hollywood." He contrasts "such soldier-cowboy-gangster directors as Raoul Walsh, Howard Hawks, William Wellman," and others with the "less talented De Sicas and Zinnemanns [who] continue to fascinate the critics." However, as in "Underground Press", the term developed as a metaphorical reference to a clandestine and subversive culture beneath the legitimate and official media.
