Researching our area of horror trailers

After looking at the typical horror trailers, I have noticed that they come into one of two categories:-

• a short, usually lasting about 1 minute, advert not telling the audience much about the film, yet just enough to grab their attention which is usually shown on the small screen, films such as 'Awake' and 'Paranormal Activity'.
• a longer, usually lasting about 2-3 minute, advert which goes into more depth of what the film is about, such as 'The Human Centedpede' and 'Vacancy', involving enigma codes and other enticing conventions such as the unique selling point such as the director's name. A typical example of this is Wes Craven, director of the famous 'Nightmare on Elm Street' is featured in the advert for 'Scream' therefore showing the audience the standard at which it should be.

The film trailers usually have about 100 shots. A typical use of this is very fast paced movement from shot to shot, incorporating the horror and action involved in the film in a short space of time. This is usually accompanied by a 'growing in intensity' style of music before it suddenly dies down and the titles appear. This would be a good route to follow as it is very conventional and would be entertaining for the audience and in particularly our selves producing the film. The trailers usually do not give away the ending as it would be pointless in seeing the film afterwards, so the trailer is a small glimpse of what it will be like. Most include titles at some point whether it be at the end, and it's a quick flash of the main cast and production staff or in between shots are the cast etc, and the title is shown dramatically at the end.
