Common Sense Note
Parents need to know that this last-man-on-Earth saga is pretty grim in the end. It depicts the aftermath of germ warfare, with whole civilian populations dropping dead in their tracks. Violence is frequent and includes much machine-gunning, car-crashing, and stabbing. A bit of the early '70s' "blaxploitation" influence is evident, in both the strong African-American characters and some vintage name-calling ("honky"). A few shots show the heroine nude, and she has a spicy sexual affair with the hero. Language includes "bastard" and "ass"; characters drink and make references to drugs. Although it's rated PG, that rating was given before PG-13 existed; it would warrant the higher rating today.
Sexual
Content
A few shots of the heroine naked (frontal and side nudity from the waist up), once in bed after sex, another time in a clothing store. References to sexual interludes and birth-control pills. Pinup girl on a wall emphasizes Neville's bachelor status.
Violence
Many characters are shot with machine gun, pistol, and sniper-rifle fire; a few are set on fire and run over by vehicles; and one is run through with a spear. A teenage boy is killed (offscreen, but the body is shown). Quick cuts of shriveled, long-dead corpses.
Language
Language includes "bastard," "ass," "damn," and an incomplete "motherf--ker." Some derogatory race-based terms ("honky," etc.). One character wears a jacket depicting an obscene gesture.
Social
Behavior
Even though he's a walking Christ metaphor by the end, Robert Neville is portrayed as a cynical, profane soldier-doctor who doesn't seem to even want to try to negotiate a peace with the mutant cult (one character who does is summarily killed anyway). The cast is multicultural, but the script is peppered with then-trendy race-baiting name calling and innuendo.
Consumerism
Car brands and fashions on display. A clip from the rock music documentary Woodstock plays.
Drugs / Tobacco /
Alcohol
Recreational drinking, references to drugs.
