Here is an interesting entry over at Cinema Viewfiner:
A black man, the last man on Earth, fends for himself in Manhattan after a global plague wipes out the rest of humanity. His loneliness overwhelms him. He slowly slips into insanity, speaking to mannequins he’s set up throughout the city to approximate some form of normalcy. Every day at noon, he pleads into a short-wave radio, announcing his location, and his intention to broadcast indefinitely, hoping to get a response. Then he finds out he’s not alone. That’s the premise behind I Am Legend (2007), right? Wrong, but who could blame one for seeing the similarities?
