14. Damnation Alley (1977)
This late '70's slice of sci-fi cheese tells the story of two men (George Peppard and Jan-Michael Vincent) who set out across a post-nuclear holocaust America in an armor-plated, missile-packing all-terrain RV, encountering extreme weather, killer cockroaches, and giant scorpions along the way. Martin says that the film, which predicts that a nuclear holocaust would knock the Earth off its axis and encase it in radioactive dust, isn't based in actual science. "I don't think a nuclear holocaust could do that, but earthquakes, especially the Japan earthquake [of 2011], have tilted our axis several inches – not enough to cause any extreme weather patterns. The further back in time we go, the less we knew about science and how realistic apocalyptic things would happen, so some of the older movies are very cheesy and don't have a very factual grasp of post-apocalyptic worlds. They tend to be more entertainment-based than truth-based."
