Underground Film refers to a genre of cinema that operates outside the mainstream film industry, often characterized by its avant-garde style and unconventional narratives. These films are typically produced with low budgets and may explore taboo subjects, pushing the boundaries of traditional storytelling. This genre has roots in the counterculture movements of the 1960s and 1970s, with filmmakers like Andy Warhol and John Waters gaining notoriety for their provocative works. Underground films often prioritize artistic expression over commercial success, appealing to niche audiences who appreciate their unique perspectives and innovative techniques.
