Set/Props/Costume/Actors: ideas

Set

I have 3 main ideas for set; The Lickey Hills (woods), Skate Park and also a house.
     I like the idea of the Lickey Hills and a Skate Park because those are typical haunts for teens in a group of friends, so the victim of my film could realistically spend a lot of time here. However, because they are public areas there is no stopping a stalker from walking through them or passing by/watching my victim, because there are no laws stating certain people cannot pass through.
    The house is a more obvious one, but I think the Stalker does need to come into her home to create a lot of fear within the audience.

Props

I think that props should include; mobile phone - she could keep getting strange phone calls where nobody talks on them and they become more and more frequent; rope/knife/leather gloves - for the stalker, these could be what he brings with him for his final act of cruelty towards my victim.

Costume

Victim: Lots of black eyeliner, messy hair, mainly dark clothing with some fluroescent bold statement colours- show she's an outcast from "the norm", but fits in with her friends
Victims friends: similar to the victim
Stalker: Dark clothes. Greys/Browns/Blacks. Longish hair, face is always mostly covered; hoods, hats, scarves etc. Gloves.

Actors

Victim: 13/14 yr old girl.
Her friends: 3 - 4 other people, mixed, around the same age
Stalker: Tall, large maile
