Thread: help on a horror screenplay idea!!?

Me and a few of my friends have decided to write and film a screenplay for extra credit in our lanugage arts class. we already know that we want 3 main characters (2 boys, 1 girl) and that it takes place in an abandoned barn (which we've found just outside of my neighborhood). Any ideas on the subject are welcome! Thanks!

also, all of the barn's windows are knocked out.

umm, maybe they get locked in the barn. and they decide to tell scary stories, but something starts killing them, i noe its tacky but hey, its an idea.

In the abandoned barn is a kind of deformed person. he has been terribly abused by others and when he sees them come in laughing and being gleeful, he feels they are going to find him and make fun of him,. so he lashes out at them
