I've been a devotee of post-apocalyptic films for several years but until perusing streaming options on Amazon today I had never heard of this 1959 film starring Harry Belafonte and Mel Ferrer. It's set in New York City and was filmed in Manhattan. Some impressive scenes and cinematography. And some implausibilities but it is 1950s Hollywood...
Highly recommend if you, too, are a fan of post-apocalyptic genre. That it is black-and-white and circa-1950s is for me a bonus. http://www.amazon.com/The-World-Flesh-Devil-Remaster/dp/B004H0M32M
Amazon is streaming a remastered version and it is excellent quality.
