The establishing shot is a close up of a timer which ticks twice.  This opens the trailer with something which will create a tense atmosphere. A dolly is used to show the first character - a distressed young woman running through a forest area. The screen blacks out and a medium shot shows the woman lighting a match and a police car pulling up behind her. The effect of this is that the character is presented as being troubled. A variety of different shots is used to show the burning building which will make the audience question what is going on. A low canted angle is used to show a car driving up to a manor house. This scene compared to the previous scene would cause confusion among the audience.
