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". Such films contrast sharply with mainstream blockbuster films, which are geared more towards linear storytelling and entertainment. Film critic Roger Ebert called Chungking Express, a critically acclaimed 1994 art film, "largely a cerebral experience" that one enjoys "because of what you know about film". For promotion, art films rely on the publicity generated from film critics' reviews; discussion of the film by arts columnists, commentators, and bloggers; and word-of-mouth promotion by audience members.
