You gotta love RED DAWN; I dont care who you are:
"We're running out of food."
"We've still got plenty of meat."
"Just stuff you shot!"

Classic dialog.

I have to say I liked Dawn of the Dead for the humor factor. (hey, it was a survival situation of a sort)

A great serious movie is The Snow Walker. While it is not a region I expect to deal with, it had some great lessons to teach about the importance of knowledge, learning, and keeping a clear head.
