heres a few of my favorite "teotwawki" type films.
not always good films but i liked them.
they fall into a few catagories, the begining of the end ,and after the end of the world.

in no order:

red dawn
28 days later
dawn of the dead / day of the dead
the stand (if you read it get the uncut version)
mad max / road warrior
the omega man
soylent green (this seems the most likey id say)
the quiet earth
planet of the apes
def con 4
hitchhikers guide to the galaxy (the world WAS destroyed after all).


for those of us who liked omega man / last man on earth and those type of films, you have to read the book " i am legend" by richard matheson.
its the book omega man was based on but its much better.
