Read the book a while ago, this one should be interesting, though in the trailer I can see it's taking a pretty big departure. In the book it's just father and son, the mother had died long ago.
Maybe they kill her off early in the movie?
Edit: I just remembered part of the story takes place right where I live which is kind of cool I guess.
2:02 of the video...
I swear I've heard that yell in some other movies or games.
