What is underground film?

Underground film refers to a genre of cinema that operates outside the mainstream film industry, often characterized by experimental techniques, unconventional narratives, and a focus on avant-garde themes. It typically embraces low budgets and non-traditional distribution methods, allowing filmmakers to explore personal, political, or social issues without commercial constraints. This genre often includes works that challenge societal norms and provide a platform for marginalized voices. Notable examples include films from directors like John Waters, Kenneth Anger, and Andy Warhol.
