So last Halloween I was watching my nieces scared of a haunted house and I was thinking what would they say if those people weren't really wearing a mask and were real monsters. SO....I've come up with a idea on writing a movie just for fun on a group of smart ass friends going to a haunted house and the monster actually being real and the scares are for the joy of the monsters and killing people as props to their house. I've never really seen a movie done like that...has anyone else? also on wither or not the idea sounds good.
