In the '50s the nuclear holocaust was never far from the popular imagination. This picture is one of many fictional efforts to show what might have happened.
By being trapped in a Pennsylvania mine, Belafonte is one of the very few people on earth (as far as we know from the film, only three) to escape annihilation. He manages to get out of the mine on his own (the first of many plot contrivances), goes to New York City and finds it depopulated, except for Inger Stevens, who eventually comes out of hiding. It's mostly a picture about loneliness. As much as we may resent the jostling masses in our midst, what if they were gone?
Actually, it spurs a fantasy, too. Imagine that you had the pickings of all of New York to yourself, and imagine that you were a handyman who could rig up generators and the like, and imagine that you found a comely woman to keep you company. Could be worse.
But we are asked to ignore too much in the picture, the fact that only one person in all of the city survived, the fact that not a single rotting body is shown on the streets, the fact that the shortwave transmissions Belafonte regularly monitors show that the rest of the world is empty, too (except, eventually, for Mel Ferrer, who was sailing during the nuclear blasts)-- all a bit too much. The film tries too hard to be an allegory when it should have been good, logical science fantasy.
Nevertheless, TWTF&TD is well worth a watch.
