Use of Sound in Diederich

The sound in our trailer, is very unconventional to those found in usual horror films. The start of the trailer immediately begins with the 'drumbeats' which automatically gives the sense of warfare, as it is a marching beat. This is very unconventional for all horror films, as following my research, I could not find any other trailers which offered such a peculiar sound straight away. However this does just add to the mystery and sense of unknown which is related with our trailer.
When this beat dies out, it is replaced with the heavy breathing from our antagonist. This gives the audience a sense that a being is watching over the couple within this film, and just intensifies the wanting to know more about the characters within.
The marching beat then replaces the heavy breathing, but a rare piece of dialogue is also used along with the heavy knock on the door. These are diegetic sounds which relate to the footage being shown. As Kyle opens the door, seeing that nobody is there. There is a loud beat, which then generates on to the background of strings, which is used throughout the rest of the clip. This beat now intensifies the action, and shows the danger that is now approaching the protagonists. The loud clap of noise is also shown when they rip the letters from the wall, and see the gas masked figure staring back at them.
As the action scenes increase towards the end of the clip, the beat is repeated more often in order to increase the speed of the action, and show the growing danger which is being placed on the individuals.
The use of the old aeroplane noise, once again shows a representation of warfare within this clip, but more importantly the speech from Winston Churchill, which says; "This is not the end, this is not even the beginning, of the end." Is a very effective tool which adds a lot of suspense to the end of the trailer, and once again links our trailer back towards World War Two.
