Horror trailer 1

I have chosen this trailer because it is an indie film, made on a lower budget and therefore with effects easier to achieve.

The feature of the trailer that could be useful is the setting, an abandoned mental institution. These places are reasonably easy to create (any modern building can be dressed up as one with the correct props), and the mere mention of the words "insane asylum" is enough to bring images of madness and brutality. Also, it is easy to justify such a place being haunted, thus maintaining the suspension of disbelief.
