Research and Planning: Existing Horror Film Trailer (Analysis)

During this trailer, many codes and conventions are used to make it obvious to the audience that this is a horror film: 

Sound: Many Sound FX are used in this trailer to emphasise the supernatural/spooky theme within the film. Also, the dialogue tells the audience that there is a villain whom is stealing children's innocence by causing them to murder their families; this alone emphasises the horror genre as it is a twisted and frightening storyline. Women can be heard screaming, men yelling and children crying, and this is effective as it makes the audience feel on edge and adds to the suspense - it draws the audience in.

Cinematography: Throughout the trailer, low-key lighting is used to make dark shadows stand out and make the audience feel on edge. Also, many low-angles were used on the 'villain' in the film, and this shows that he/it has power and influence on the innocent children he is corrupting and making them kill members of their families.
Mise-en-Scene: Costumes and Makeup are used excessively in this trailer to emphasise it as a horror genre - the villain is made up to look supernatural, and this is something that horror films use often to bring a sense of the 'unknown' - by using something supernatural, it gives us the sense of being helpless because we have never experienced it before and therefore do not know how to fix/stop it.

Editing: There are many cut-ins and fade outs in this trailer, as well as many zoom-in's and zoom-outs. These are often used in horror trailers to keep the audience tense and on the edge of their seat. The cut ins are used to give us a shock i.e suddenly noticing there is someone stood behind her that we could not see in a different shot etc.
