DEAD RUN

This is an example of a zombie made by a media group last year however this is a teaser trailer and not a film opening.
The main difference between ours and theirs is that theirs is much more of a serious zombie fiml whereas ours is very tongue-in-cheek.
The use of low lighting and the silhouette adds a typical horror film effect which draws the audience in and plays on their expectations. The wide range of zooming alerts the viewer to and maximises the connatations of danger which increases the tension.
The use of a bigger number of actors makes a very realistic school environment however, the loud speaker makes it very american and this is not something that British people can really relate to.
