Arthouse Classics
An art film (or art house film) is typically an independent film, aimed at a niche market rather than a mass market audience. It is "intended to be a serious, artistic work, often experimental and not designed for mass appeal", "made primarily for aesthetic reasons rather than commercial profit", and contains "unconventional or highly symbolic content"
Experimental Films
Experimental Cinema, or avant-garde cinema is a mode of filmmaking that rigorously re-evaluates cinematic conventions and explores non-narrative forms or alternatives to traditional narratives or methods of working. Many experimental films, particularly early ones, relate to arts in other disciplines: painting, dance, literature and poetry, or arise from research and development of new technical resources.
