Research into Film Trailers

In my research of different movie trailers i have noticed what the producers and editors include. The main aim of a trailer is to not give to much away and to make the audience want to go see the film. Usually the trailer will explain what the film is about and sometimes show scenes near the end of the film to grad the audiences attention. In the horror genre this is normally common where they have parts near the end of the film showing. As well as that they also include a scary scene to make the audience jump bringing in the horror genre. A good example of this is the new film called Sinister. Throughout the trailer the story is explained through text on the screen. There are a couple of scenes showing the mysterious character to make the trailer scary. The reason why its a good example is because the final scene of the trailer is where all the children are sat in a dark room. You notice the children and keep your eye only on them. Next thing that happens is the scary character jumps out from the left. Adding this right at the end of the trailer makes the audience jump and remember the trailer after the film they are watching.
