Any technological advance toward mimicking reality then would be great for a film theorist like Bazin who believed sound (once it was seemingly perfected as a filmic technology) was an amazing boon for film. Other movements toward reality would be color, stereoscopic sound, anamorphic format (widescreen), 3D, surround sound, maybe even CG in certain circumstances. All these advancements allowed film to create this window through which the subject matter is viewed. the difference between realists and other theorists might be akin to the difference between two verbs associated with the art of film, "capture" and "create". Formalists would say that art is "created" more or less, and realists would argue that art is "captured".
But, here is the question: Do you agree? Is a film that is more real closer to (if not fully) art? What are some examples of this?
I personally would say that this goes beyond just "lifelike" acting or any other technical aspect of the production but into the content as well. A good example of this is Italian Neo-Realism. In Italy, after World War II, film was not just seen as an entertainment, but as a representation of the times. An event around which, audiences might find a catharsis for their troubles. Two of my favorite of these films are by the Italian director, Vittorio De Sica: They are The Bicyle Thieves and Umberto D.
What are some of your favorite "realistic" films?
