Ben Cortman is the main antagonist of Richard Matheson's 1953 novel I Am Legend, and the 1964 film The Last Man On Earth, its first film adaptation. He is the neighbor of protagonist Robert Neville (named Robert Morgan in the film) who becomes a vampire after being infected by a virus, and leads his fellow undead in trying to kill his former friend.
He was portrayed by the late Giacomo Rossi-Stuart.
