Halloween Opening sequence analysis

Halloween is a 1978 American independent horror in the fictional suburban town of Haddofield, Illinois, USA on Halloween.
A psychotic murder institutionalized since childhood escaped on a mindless rampage while his doctor chases him through the streets.
Halloween was produced on a small budget of $320,000 and grossed a massive $47 million at the box office in the USA alone, equivalent to over $150 million as of 2008, becoming one of the most profitable independent films of all times.
Many critics credit the film as the first in a long line of slasher films inspired by Alfred Hitchcock's Psycho (1960). The movie originated many cliches found in low budget horror films of the 1980's and 1990's. However, the film contains little graphic, violence and gore.

The text in the title sequence is orange, representing Halloween, gradually turning to red, letting off a negative connotation of blood and danger. There is a black background making it clear to the audience that the film is bounf to include elements of darkness and violence. There is also a pumpkin in the background, an establishing shot first shows the pumpkin in the distance, the slow zoom in towards the pumpkin represents an animal zooming in on its prey, getting ready to attack. The titles constantly fade in and out whilst the music gets louder and faster, sounding as if there is a chase going on. The pitch often changes from high to low within the title sequence, which helps to build tension.
During the opening sequence a subjective point of view shot is used once the person has put the mask on which makes the audience feel as if they are behind the eyes of the killer. We see a knife been picked up and the person moves around the house using a forward dollying shot, as if he's searching for his victim, all the while the music gets higher and louder creating tension, as the audience aren't sure what the knife is about to be used for.
As the killer walks up the stairs you can hear the diegetic sound of the young girl humming, which helps to create a tense atmosphere. The music suddenly changes to a very high pitched sound representing the scream of somebody in grave danger as the killer behing the mask stabs the girl to death.
Unexpectedly, the killers identity is revealed and is infact the girls younger brother. John Carpenter cleverly used the camera angles to trick the audience by protraying the killer to be a lot older and taller than he is.. The entire opening scene is a long take from the killers point of view, up until the very last shot when it cuts and Michael is revealed as the man behind the mask. This could then make the audience believe the film contains many more twists.
