That would make an awesome suspense/horror/thriller type deal, let me just say that!
A lot of my book ideas would probably do better if I made them into movies to be honest.
My mom found some website where you can vote, along with others, on what movie summery you find most appealing and you get a cut of the profit when/if it's made. I wonder if there's one like that where you can submit ideas. *goes off to ponder*
