Mise-en-scene: Nightmare on Elm Street opening scene

What props are in the opening sequence?
There are a number of different props in the opening scene of Nightmare on elm street. It starts of with a scarred hand searching for metal objects in what looks like some sort of scrapyard or waste. H eventually chooses a pair of gloves that are both filled with holes and some sort of sharp blade.We then see the character move over to a work bench to combine these objects into a weapon.

I believe that the the use of these items so early in the film are used to captivate the audience and to make them wonder what this unknown character is going to do with this contraption. It also tells me that the producer wants to make the let the audience know that this film will contain a lot of violence and danger.
The setting is never made clear in the opening scene, but from watching it I can infer that it is some sort of abandoned factory, I know this because the building is completely empty, it is completely silent apart from the odd creak. The use of an empty building makes the audience want to continue watching to find out whether there is a story behind it.

What lighting and colour used in the opening scene?
The lack of lighting in this opening gives a dark and miserable effect, it tells me that this abandoned building may have some sort of history, and this will make the audience want to carry on watching to find out. It is then very strange to see the mysterious character who is creating these weapons wearing a red and black jumper, this tells me that this character may have had a happy life once, one that did not consist of darkness and isolation.

What does the characters facial expressions and costume tell me about them?

Towards the end of the opening scene, you are introduced to a new character. This character is a young girl who has no reason to be in an abandoned building. Her costume also tells me about her, she is wearing a night gown that normal people would wear where when they are going to bed, this portrays the young girl as being very vulnerable, this is further developed by the young girls facial expressions, she has a very confused look on her face, which tells the audience that she has no idea where she is and why she is there.
