I checked out the movie 'Devil' written by this M.shyalaman guy, then I researched him, and he had a movie called Signs.
I looked for the movie trailer and found this film called Signs as well
This is it. It was amazing.
Its sad though, I'm thinking of humanity. That guy who acted in Signs was Nick Russell.. Even being as good as him in acting his career only moved up abit. Which led me to a point in thinking that millions of people must be dying to make it into hollywood
