Scream costume idea

For our main task we want our main villain to look threatrening and dangerous. We also want his identity to be unknown beacuse this will make his identity secret. We can do this with a suitable costume and mask, something that is dark will make the audience associate the villain with death.

The costume used in Scream is a good idea of what we want our costume to be like. It is important that the killer has a good costume otherwise our film may lose its scare factor.
