Wrong Turn 3 Left For Dead-Official Teaser Trailer

In this trailer there a few production values shown. It doesn't state the director, production company, budget, or any stars, although the iconography does show it's genre. The aspects of the movie it shows are aimed at the target audience, as only horror fans would like the gore shown. It still has inter titles which are read by a voice over (typically a authoritive male voice). The voice over is saying one sentence which is broken up into clauses, with dialogue and action in between. The inter titles/voice over explain the complication but doesn't give the resolution. The music builds up throughout and like the conventions of a trailer it doesn't reach the crescendo. The name of the film is stated by the voice over at the end, which is used for emphasis and memory.
