Postmodernist film is a classification for works that articulate the themes and ideas of postmodernism through the medium of cinema. Postmodernist film attempts to subvert the mainstream conventions of narrative structure and characterization, and tests the audience's suspension of disbelief. Typically, such films also break down the cultural divide between high and low art and often upend typical portrayals of gender, race, class, genre, and time with the goal of creating something that does not abide by traditional narrative expression.
