The Last Man on Earth is a 1964 black-and-white 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, directed by Ubaldo Ragona and Sidney Salkow, and stars Vincent Price. 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.
