Analysis of inception trailer

This trailer for the film inception shows some of the scenes from the film to give the veiwer an idea of what it is about, but they don't give to much away so that the veiwer doesnt know the outcome of the film. it uses a backing track throughout the trailer to make it more intense. The trailer has a voice over at the start from the main charictor (Leonardo Dicaprio) which rund untill about half way through. There is then some dialog from the film as it progresses but doesn't reveal much about the film. It shows that the film is directed by the same people that directed the dark night film which was a big success and indicates that this film could be just as good. They use writing aswel which gives an idea of what the film is about but at the same time doesnt explain what is going to happen.
