Overview
The Omega Man (1971) is the second and perhaps most culturally emblematic adaptation of Richard Matheson’s influential novel I Am Legend. Starring Charlton Heston at the peak of his post-Planet of the Apes career, the film blends dystopian science fiction, action thriller, Cold War paranoia, and a touch of countercultural sentiment. Though it takes considerable liberties with Matheson’s text, The Omega Man holds a unique place in 1970s science fiction cinema—a product of its time and a precursor to the zombie/infection-apocalypse genre that would flourish decades later.
Plot Summary

Set in 1977 Los Angeles—just a few years into the future at the time of its release—The Omega Man opens in a world devastated by biological warfare between China and the Soviet Union. The resulting plague has wiped out most of humanity. One man, Colonel Robert Neville (Charlton Heston), a former Army scientist, survives due to an experimental vaccine he had injected into himself in time.
Neville wanders a deserted, decaying city by day, driving a convertible through empty streets, watching movies in abandoned theatres, and scavenging for supplies. By night, he barricades himself inside his fortified townhouse to avoid The Family—a nocturnal cult of diseased, albino-like mutants who blame technology and science for the fall of mankind. Led by the deranged Matthias (Anthony Zerbe), The Family seeks to destroy all remnants of the old world, including Neville.
The core of the story revolves around Neville's lonely existence, his increasing psychological strain, and his eventual discovery of other survivors—including the fiery Lisa (Rosalind Cash) and her brother Richie (Eric Laneuville). As Neville works to cure the disease using his own blood, a final confrontation with The Family looms, one that forces Neville to make the ultimate sacrifice.
Charlton Heston as Robert Neville
Charlton Heston’s portrayal of Neville is quintessential Heston: rugged, stoic, self-reliant, and morally unshakeable. He brings gravitas and charisma to the role, making Neville more action-hero than tortured philosopher (as in Matheson’s novel). Yet, Heston’s performance captures a deep undercurrent of weariness and isolation, especially in the early scenes where he talks to mannequins and quotes Woodstock to himself in an empty movie theatre.
This version of Neville is also an avatar of science and rationalism, a man who clings to the remnants of civilization—classical music, fine liquor, Western art—while trying to outwit a society that has literally and figuratively gone dark. Heston's screen presence carries the film even through some of its more dated or stilted moments.
Rosalind Cash as Lisa
Rosalind Cash, in one of her most memorable roles, provides a sharp contrast to Heston’s stoic formality. Her character is assertive, sceptical, and refreshingly modern. Cash brings a sense of realism and energy to the film, and her chemistry with Heston—especially in the context of an interracial romance, which was still relatively rare in American mainstream cinema—is progressive for its time.
Lisa’s presence also brings the story back to a more human level. She forces Neville to reckon with the broader implications of survival—not just for himself, but for the species. Her transformation late in the film adds emotional weight to the climax, even if her character arc feels slightly rushed.
Anthony Zerbe as Matthias
Anthony Zerbe’s Matthias is a compelling antagonist: a former news anchor turned fanatical cult leader. With his pale skin, dark robes, and hypnotic rhetoric, Matthias evokes a mix of religious zealot and totalitarian demagogue. His hatred of Neville represents the rejection of science and the old world in favour of a regressive, anti-intellectual ideology.
The Family, robed and hooded, bearing torches and spouting anti-technological dogma, are like a medieval mob transplanted into a post-nuclear future. They serve as a grim parody of cultural backlash—the fear of what happens when reason is blamed for ruin.
Visual Style and Direction

Director Boris Sagal creates a chilling atmosphere through the use of Los Angeles’s empty streets, shot mostly in the early morning to simulate the post-apocalyptic silence. The opening scenes—Neville speeding through a lifeless city in broad daylight—are haunting and effective, predating similar imagery in 28 Days Later (2002) and I Am Legend (2007).
The film's visual contrast between light and dark—sunlit ruins by day and shadowy terror by night—reinforces the duality of Neville’s world. The action scenes are typical of 1970s genre fare: a bit clunky, often backed by funky music, but occasionally striking, especially the night-time attacks and Neville’s final stand.
The production design uses real locations and minimalist set dressing to create a convincing desolation. The Family’s scenes are more stylized, with washed-out lighting and eerie red filters giving their meetings a nightmarish, quasi-religious vibe.
Themes and Subtext
The Omega Man is steeped in the political and cultural tensions of the late 1960s and early 1970s:
Science vs. Religion/Anti-Science: Neville represents reason and scientific progress, while The Family stands for a reactionary rejection of those values. This reflects real-world anxieties about nuclear proliferation, distrust in institutions, and the countercultural backlash against technocracy.
Race and Integration: The romance between Neville and Lisa is notable not only for its rarity in 1971 but also for what it symbolizes—a potential future where survival demands cooperation across social divides.
Isolation and Psychological Survival: Neville’s descent into semi-madness during his solitary years echoes themes found in other apocalyptic fiction. His need for connection, companionship, and meaning speaks to a deep human vulnerability.
Martyrdom and Legacy: The film diverges from Matheson’s original novel by turning Neville into a Christ-like saviour figure. His blood—literally—becomes the cure for humanity, and he dies in a cruciform pose. This Christian symbolism is heavy-handed, but it fits within the era’s cinematic trends (see also Planet of the Apes and Soylent Green).
Differences from the Source Material
Richard Matheson’s I Am Legend is a far more psychological and intimate novel, focusing on the fear of the unknown, the subjective nature of monstrosity, and the idea that Neville himself is the outlier in a new evolutionary paradigm. The Omega Man eschews much of this ambiguity in favour of a more straightforward man-versus-mutants narrative.
While Matheson’s creatures were essentially vampires, the film reimagines them as plague-afflicted mutants. This change sacrifices some thematic depth but aligns better with the film’s Cold War and countercultural framing.
Cultural Legacy
Though not as critically acclaimed as later dystopian films, The Omega Man has had lasting influence. It inspired everything from zombie cinema (especially George A. Romero’s The Crazies) to the post-apocalyptic aesthetics of Mad Max and The Walking Dead. Its racial and political subtexts have become more appreciated with time, and its place in the evolution of I Am Legend adaptations is pivotal.
Charlton Heston’s performance, while occasionally theatrical, helped define the stoic lone survivor archetype. The image of Neville in leather jacket and mirrored sunglasses, roaming empty boulevards, remains iconic.
Final Assessment
The Omega Man is a film of contradictions: campy yet sombre, dated yet thematically resonant, action-packed yet introspective. Its visual storytelling, ambitious themes, and committed performances (especially from Heston and Cash) elevate what could have been just another sci-fi B-movie into something richer, if still uneven.
While purists may balk at its divergence from Matheson’s novel, the film succeeds on its own terms—as a bold, sometimes overwrought reflection of its time, grappling with questions of survival, faith, and the future of civilization.
Verdict: A flawed but fascinating sci-fi parable with enduring relevance and memorable visuals. Charlton Heston shines in one of his defining genre roles.
