Another Vincent Price classic, The Last Man on Earth is an early movie adaption of the novel by Richard Matheson titled I am Legend.
Dr. Robert Morgan (Vincent Price) is The Last Man on Earth. Everyone else on the planet has been turned into vampires by a strange virus and only he remains human. By night he must hide from the vampires but by day while they are vulnerable he hunts them, all the while hoping beyond hope that there is someone, anyone, still out there.
