The Blair Witch Project (1999)

The fact this entire film, let alone trailer, was filmed using hand-held camera makes it very different from most other horror films, as, hand-held may be used when trying to create panic or sudden fear, but not the entire way through the film. This trailer gives us relevant information into the plot; we know why they are doing what they're doing etc. It also gives us a conventional location in a forest and the possibility of a final girl, due to the characters we see. Personally I do not find this trailer very effective as we are not given anything to identify the horror with, apart from the forest, some people may argue that this leaves the audience is suspense, however I feel as though to do that they have alienated them from the plot.
