A sci-fi/horror classic from 1964. A plague envelops the earth, decimating the population and leaving one man still alive: a scientist who exhibits a strange immunity to the deadly disease. As the rest of humanity slowly turns into bloodsucking vampires, he must use all his knowledge to survive their onslaught. The original adaptation of Richard Matheson's classic novel I Am Legend, it remains a horrifying film that influenced the creation of NIGHT OF THE LIVING DEAD plus countless imitations.
