Wow, if I were a film producer and some guy came to me with this screenplay i probably would ask him if he's on crack!
I fell in love with this movie since the first puppet scene on the beginning.
this makes you think about a lot of philosophical questions & you can find that you have anything to proof that you never'll know if someone had been on your head?
you probably would say, "Bah! thats not possible" but I can reply you.."How are you sure?"
