Preparation of staring to film

Actors:

The decided actors in our film opener are going to be me, the unsuspecting victim of Horseman; Reid, the friend that the unsuspecting victim calls on the phone when he is spooked; and Jason, who will be playing the murderous Horseman.
Costumes:

The clothing of the regular people will be nothing out of the ordinary. However, Horseman will be dressed in cut up dirty jeans, a dark hoodie over his head, a styrofoam head with a horse mask on it, and horse hooves on. 

Props:

Since this is going to be shot in a house, there are no props that are out of the usual or not available to my group-mates. We will need a steak knife, a phone, and a shower towel as our list of props needed to execute this opener. 

Locations:

The entirety of this opener will be shot at my house. Mostly in the living room area, balcony, and bathroom. 

Dates and Times:

We are planning on shooting these scenes next weekend (Feb. 19th and 20th). 

Scripts:

We will only have to write two scripts: one for our unsuspecting victim, and one for the friend that is one the phone. Horseman does not speak at all in the film opener, so no script is necessary for him. 

Film equipment:

The equipment we will need for shooting is a iPhone microphone for enhanced audio quality, an iPhone 4K camera, and a production application on an iPhone.
