Actors/Costume/Location Planning

Actors/Actresses:
Jogger: Alice Hobson
Mystery Man: Myself 

Alice is appropriate for the part we have given her because she's a young woman so she will be able to jog much easier than an older woman. Also Alice is an active sporty person so she will look more natural while running. These two features will make the scene more believable.
I am suitable for the part of the man because I am tall and have the ability to make my hair neat. I will not need to act much other than a close up of my hands, an over the shoulder shot and a close up of my mouth.

Costume:
Jogger: Casual/Running clothes (leggings, tshirt, trainers, earphones, messy hair/bun)
Mystery Man: Dark Clothes (Black Jacket, Black Jeans, Black Shoes and neat hair)
The costume for the Jogger needs to be simple because she is only a runner and would not be dressed up. 

The costume for the man needs to be dark to create a sense of mystery and suspense as to who the man is.

Location:
Bedroom
Park
We are using the bedroom for the opening shots such as shots of the jogger putting shoes on or putting on music and headphones and looking out the window.
We are using the park for the jogging scenes to suit the stereotypical idea of people jogging in parks.
