All forms of story-telling are to provide escapism, to which every film does to varying degress of success. I suppose certain types of films could be classified to art, but this is stricly open to inerpretation by people, as art can mean different things. (For instance, Troma Entertainment refer to themselves as producing "independent art", and their best output are films like The Toxic Avenger and Surf Nazis Must Die). The films of Ed Wood are also seen as post-modern art by many of his fans, so that just begs the question, how do you classify art in terms of film?
