The Omega Man is a 1971 American post-apocalyptic action film directed by Boris Sagal and starring Charlton Heston as a survivor of a global pandemic.
It was written by John William Corrington and Joyce Corrington, based on the 1954 novel I Am Legend by American writer Richard Matheson.
The film’s producer, Walter Seltzer, went on to work with Heston again in the dystopian science-fiction film Soylent Green in 1973.
In March 1975, a Sino-Soviet border conflict escalates into full-scale war in which biological warfare destroys most of the human race. U.S. Army Col. Robert Neville, M.D., is a scientist based in Los Angeles. As he begins to succumb to the plague, he injects himself with an experimental vaccine, rendering him immune.
By August 1977, Neville believes he is the plague’s only immune survivor. Struggling to maintain his sanity, he spends his days patrolling the now-desolate Los Angeles, hunting and killing members of “the Family”, a cult of plague victims who were turned into nocturnal albino mutants.
The Family seeks to destroy all technology and kill Neville, who has become a symbol of the science they blame for humanity’s downfall. At night, living atop a fortified apartment building equipped with an arsenal of weaponry, Neville is a prisoner in his own home.
Dr. Robert Neville is the only survivor of an apocalyptic war waged with biological weapons. The plague caused by the war has killed everyone else except for a few hundred deformed, nocturnal people calling themselves “The Family”.
