Poetic language and the filmic medium

As I read Roman Jakobson's analysis of the poetic function in language, I couldn't help but compare many of his linguistic analyses with film as an expressive medium. Jakobson states that every message has an addresser and an eventual addressee. Film can also be viewed as having an addresser and addressee, but these notions in film seem a bit more fragmented and complex to me. As where linguistic communication usually involves one addresser, the speaker, film usually involves multiple people in the conveying of a message. Most evidently, the director and screenwriters can be considered addressers, but what about the actor and the cinematographer? I believe that these people also play important roles in the passing on of the message through the filmic channel or code. Can anyone think of examples in which film becomes metafilmic? I think this ties in nicely with what professor Rosen discussed in class on wednesday when he discussed Bleu Shut. By tying in clips from all different types of filmmaking, the film itself becomes a critique of the filmic code. Also, the addressee in film, the audience, is drastically fragmented for obvious reasons. We can discuss in section more ways in which film connects with poetic language...
