Legally Blonde - Opening

http://www.youtube.com/watch?v=WejK9NeyOzk
The film begins as a  out-of-focus close-up on what appears to be blonde hair. this straight away creates a link in the audiences' minds to the title of the film. 

the credits shown over the images are in a fluorescent pink with a very swirly font, giving a very "girly" appeal.

as the credits appear the shots reveal a lot about the people involved in the film and where it is set.

when the camera is focused on the blonde hair we see that it is perfect, and brushed with a set of hands that have a perfect manicure and wearing a tiffany silver bracelet also suggests that not only is the character very feminine and "perfect" she also appears to be wealthy. the same message is perceived with a close up of the girl putting on a tiffany necklace with perfect skin and hair etc.

as the camera cuts to the bike basket the name "Elle" is written on a card envelope, giving a name to a main character. as the shots cut from the bicycle ride with a variation of long, mid and close up shots which establish the setting as a girly place with perfectly mowed lawns, fountains etc, that suggest money and wealth as well as 'perfection'. the shots cut from those establshing shots to close up shots of the girl in her environment and show viewers that she is a perfect girl who takes care of her self in a very stereotypical way, from the shaving her legs to painting her nails to brushing her hair. all these shots are done as close ups so not to reveal her full character, creating enigmas in viewers' minds.

the lighting used indicates a happy, sunny day and the bright colours suggest this also. the main colour common in a vast majority of the shots is pink, a very feminine colour and suggests to audiences that this is a girly film or a "chick flick"

the use of slow motion in parts create a soft effect and suggests a gentle feel, almost saying these girls are dainty. the slow motion next to a whip pan shows a change in location and subject and draws the eye to the screen if you are distracted as a sudden move.

the music that is ongoing in the background is upbeat and sung by a woman. the lyrics "perfect day"again suggest the idea of perfection in audience's minds.

Halloween - Opening Sequence

The film begins with the famous, fact-paced piano music played while the credits appear. the credits appear on screen as a red/orange on a black background, two colours you immediately associate with the Halloween holiday, also, while the credits are shown we are in view of a carved pumpkin. again, another symbol of Halloween. as the credits draw on the pumpkin is zoomed in on very slowly until you are focused of the eye of the pumpkin. this sets up the mood for the whole film as a scary movie.
as the credits fade to blackout, the sound of children's chanting is heard, they sing about Halloween, which again suggests that it is Halloween night. this is a deceiving aspect as this could be considered an innocent thing as its children, but it could also be seen to be freaky and spooky, creating a number of enigmas. the sound then fades and you are only left the sound of a quiet street at night.  
setting and time etc are established through many things, the pumpkins and colouring suggest that it is Halloween, the title stated where and when the shot is set "Haddonfield Illionis 1963"
the film's first shot is a long shot so the viewers are in full view of a "normal" suburban house at night. the only sounds to be heard are faint noises such as an owl's "hoot" and birds chirping. its not until the camera begins to move with hand-held quality that we realise this is a point of view shot, though we don't know who's view point we are seeing, creating a number of enigmas, e.g. "who's eyes are we seeing out of?" "why are we going up to that house?" "what is the relationship between the character and that house?" etc.
as the lights upstairs turn off the high pitched violin is played, this is an uncomfortable noise and next to the silence is very unsettling and would make audiences jump, suggesting that something bad is/will be approaching.
the lighting used throughout the opening scene appears to have not made use of artificial light, only street lamps for outside ans indoor lighting for inside the house.
as we enter the house the high pitch stays but extra music is added to pace it and bring suspense and tension to the picture.
the only clear dialogue throughout the opening is "Michael" which is directed at the killer, humanising him and giving him a gender/name.
When the mask is placed on the killer it obscures the audience's vision as it would the character so we feel as oblivious to him as what we see and what he sees/learns are exactly the same as what he does.
as the killer moves up the stairs, the lighting becomes darker, suggesting that we are walking into the unknown s we cant make anything clear.
as the killer walks up the stairs the sound of a  grandfather clock is heard, the steady pace and deep tone create great, uncomfortable suspense.
the clothes on the floor and the mess of the bed shown as the killer looks around establish what the couple were up to before he left.
the sound of the stabbing is quite vicious and creates an obvious image in the mind of the girl being stabbed though the knife is never seen making contact with her.
once the mask is removed, it is the first time we view the killer and it shocks audiences as it is a young, innocent looking boy, dressed up for Halloween, creating the idea in viewers' minds "looks can be deceiving".
