Synergy between Trailer/Cover/Poster

There are many ways how the synergy is maintained throughout the marketing process.

The example I am going to focus on is The Dark Knight Rises.  This film is one of this years biggest blockbusters.  One of the ways the synergy is maintained is through the Batman image in the center of the image, this uses the rule of thirds concept.  On each of these different types of media the Batman is the main focus of the media.  This is an example of synergy because this the Batman is in each different type of media.

Another way synergy is maintained is the same phrase on each type of media.  The phrase is " The Legend Ends",  on the poster it is on the bottom, on the front covers it is in the center and it is at the end of the trailer.  This synergy will make the viewers remember this phrase and therefore they will go and see the film because they remember the phrase.
