Representational......
The brick wall of representation functions as a background in the poster and tells us the we are in
an urban environment. The paint of the abstract images mimics graffiti with paint dripping
down the wall implying rebellion, and the light splashing across the image tells us
that it is night and that the movie will be dark. Essentially we are given a
setting for the story of the movie.
...Abstract...
In the abstract level the we see the image of a red bat with two black circles above it which transform the whole into a face similar to the Joker. This causes the bat, which symbolizes batman to bounce back and forth between the symbolic level of batman and the abstract level of Jokers mouth. The abstract level pops the most with the red bat and high contrast of the black eyes in the center of the poster.
......Symbolic
The symbolic level holds all the pertinent information; what - The Dark Knight; when - 2008;
who - Warner Brothers, Legendary Pictures, DC Comics; and where (to get more info) - www.thedarkknight.com. It also hints to the content of the film as in the main villain,
the Joker, with the "WHY SO SERIOUS?" phrase at the top and the hero with the
symbol of the bat. It is the last level we see in the design of the movie poster.
