This is a previous years trailer for a zombie film.
Unlike our approach to a zombie, they have gone for a serious, horror sci-fi mystery.
The use of low lighting and the silloutte gives a mysterious and a typical horror film feel, this draws the audience in. there is also a wide range of zooming which alerts the viewer and also maximise the connetations of danger, which increaeses tension.
The use of a bigger number of cast for the students gives a very realistic school environtment, however the loud speaker digetic sound for the annpouncement gives a very american feel to the extract.

(To be improved.)
