The Last man on Earth - 1964

The Last Man on Earth is a 1964 post-apocalyptic science fiction horror film based on the 1954 novel I Am Legend by Richard Matheson. The film was produced by Robert L. Lippert and directed by Ubaldo Ragona and Sidney Salkow, and stars Vincent Price and Franca Bettoia. The screenplay was written in part by Matheson, but he was dissatisfied with the result and chose to be credited as "Logan Swanson". William Leicester, Furio M. Monetti, and Ubaldo Ragona finished the script.
It is 1968, and Dr. Robert Morgan lives in a world where everyone else has been infected by a plague that has turned them into undead, vampiric creatures that cannot stand sunlight, fear mirrors, and are repelled by garlic. They would kill Morgan if they could, but they are weak and unintelligent. Every day Morgan carries out the same routine: he wakes up, marks another day on the calendar, gathers his weapons, and then goes hunting for vampires, killing as many as he can and then burning the bodies to prevent them from coming back. At night, he locks himself inside his house.
