The Omega Man
Science fiction took a grim turn in the 1970s--the heyday of Agent Orange, nuclear peril, and Watergate. Suddenly, most of our possible futures took on a "last man on Earth" flavor, with The Omega Man topping the doom-struck heap. Charlton Heston plays the government researcher behind the ultimate biological weapon, a deadly plague that has ravaged humanity. There are two groups of survivors: a dwindling band of immune humans and an infected, psychopathic mob of light-hating quasi-vampires.
