"Panic In The Year Zero" One of the best low budget films from the 1960s. Good acting and drama with almost no special effects. A man and his wife and daughter flee from a nuked Los Angeles. It's one of the best TSHTF movies i've seen. I highly recommend looking for it online from a free torrents site. Humans at their worst and finest.
Oooo! nuther one...
Burn Notice
good spy lessons and important knowledge like not wasting time trying to break in to a fortified door, but just break through the flimsy siding and drywall next to it
