The Last Man on Earth is a great film to watch alone. Horror veteran Vincent Price plays Dr. Robert Morgan, a desperate and lonely man who's left alone in an apocalyptic world; A world ruled by zombie-like vampires as a result of a widespread plague. These vampire zombies are highly reminiscent of George Romero's walking dead in Night of the Living Dead. Price does a remarkable job interacting with practically nothing. He's alone throughout the majority of the film. His performance largely carries this low budgeter. When you watch the movie alone, you really feel where his character is coming from and a sense of hopelessness is established. The Last Man on Earth is really a thought-provoking, creepy classic. I recommend it be watched with Charlton Heston's The Omega Man to see another take on the same story (both were based on Richard Matheson's "I Am Legend").
