The World, The Flesh and The Devil (1959)

Ralph Burton (Harry Belafonte) is a coal miner who gets trapped in a nearby Pennsylvania mine!  When he finally escapes the mine he discovers the world up above has changed!  There are no people!  Destruction has hit!  He marks a map from his starting location, which actually seems like he is marking the area of Bellefonte, Pennsylvania (an inside joke?) with a destination route to New York City…

 

 

See the first part of this movie here!  Clip ends with him marking the map (see min 15)!
