Locations
We will use the media room for the location of the revision session. We can also use it for the scenes with the killers preparing as none of the room will be shown as they are all close ups. We can use the field for the shots of the killers approaching the college to ensure continuity.

Mise en scene
Lighting: we will use lots of low-key lighting especially for the scenes involving the killers. Although we can't shoot it at night we plan to darken the scenes during the editing process to make it more sinister as though it were night.
Costumes: The victims will obviously just be wearing what they would on a normal day. We also decided the killers would wear normal clothes - jeans and hoodies with the hood up. We also had one of the killers in a 'Scream' mask to introduce the idea of their obsession with the movie though it won't be explained in the opening. Their normal clothes will also add to the enogma code as it suggests that they could be anybody and that seemingly normal people can have these dark secrets or mental problems that nobody knows about.
Props; Scream mask, Knife, Watch.

Soundtrack
We plan to use this as a non-diegetic sound throughout our opening:

The song was composed specifically for a film so its unlikely that many people will have heard it before or recognise it if they have. This will hopefully make the audience feel less comfotable than if they knew the song well which is what a thriller should ideally do.
