Common Sense Note
Parents need to know that Seeking a Friend for the End of the World is a low-key romantic dramedy set during the last few weeks on Earth before an asteroid hits. As characters try to figure out how to cope and identify what matters most to them, there's a fair bit of uninhibited behavior, from excessive drinking to drug use (cocaine, heroin, weed) to casual sex and desperate hook-ups. That said, the movie's focus is much less on that reaction to the end of the world and much more on finding clarity and peace. Two characters have sex (nothing sensitive shown), and many others talk about sex or make sexual advances. Strong language includes "f--k" and "s--t"; violence includes two suicides (one direct and one via hired assassin) and rioting. Despite all this -- and the general sense of bleakness/despair underlining everything -- Seeking a Friend is actually very sweet and romantic.
Sexual
Content
Two characters have sex fairly early in the movie. Nothing besides kissing is shown, but they talk about it afterward. A character's wife tries to seduce Dodge, but he rebuffs her. In a diner, friendly waitresses and waiters make out with each other and with the main characters; it's implied that an orgy is about to begin. A woman flirts heavily with Dodge, but he isn't interested. Additional kissing.
Violence
A friendly truck driver thinks Dodge has been sent to kill him (people are hiring assassins to take them out before the end of the world). Shortly after, the driver is abruptly (and shockingly) killed by a single bullet; some blood is shown, and a dead body. Crowds riot, setting fires and causing destruction to people and property; there are gunshots and glimpses of dead bodies. A suicidal man falls on a car without warning (broken glass, a little blood). One character has a bunker full of weapons (and other survival gear). Occasional arguing, and a general sense of peril/despair.
Language
Strong language includes fairly frequent use of words like "f--k" (written and spoken in various forms), "s--t," "d--k," "p---y," "oh my God," "a--hole," "damn," "dammit," "oh my God," and "tw-t."
Social
Behavior
Although the movie presents a pretty bleak situation, the end of the world forces characters to find a certain purity and clarity in their lives. They must find the thing or person they love best to spend their final days with. Some characters struggle with discovering just what that thing is, while others try to find hope in possible survival. Ultimately, love, companionship, and acceptance are valued above all else.
Consumerism
Coke products are seen a few times; also Colgate, Dunkin' Donuts, ESPN, and some car models (notably Smart Car).
Drugs / Tobacco /
Alcohol
Adults drink heavily and do drugs (cocaine, heroin) at a debauched "end of the world" party. They're seen roaring drunk and/or high, and they urge kids to try the substances, too. Dodge drinks cough syrup with codeine over several scenes early on, to the point of drunkenness. Penny smokes marijuana to both help her get to sleep and to wake up. Some cigarette smoking as well.
