... horror/science fiction novel about a plague that ravages a futuristic Los Angeles. The infected in I Am Legend become vampire-like creatures and prey on the uninfected. Discussing the creation of Night of the Living Dead, Romero remarked, "I had written a short story, which I basically had ripped off from a Richard Matheson novel called I Am Legend." Romero further explained: I thought I Am Legend was about revolution. I said if you're going to do something about revolution, you should start at the beginning. I mean, Richard starts his book with one man left; everybody in the world has become a vampire. I said we got to start at the beginning and tweak it up a little bit. I couldn't use vampires because he did, so I wanted something that would be an earth-shaking change. Something that was forever, something that was really at the heart of it. I said, so what if the dead stop staying dead? ... And the stories are about how people respond or fail to respond to this. That's really all [the zombies] ever represented to me. In Richard's book, in the original I Am Legend, that's what I thought that book was about. There's this global change and there's one guy holding out saying, wait a minute, I'm still a human. He's wrong. Go ahead. Join them. You'll live forever! In a certain sense he's wrong but on the other hand, you've got to respect him for taking that position.
