Common Sense Note
Parents need to know that Bernie is an eccentric, entertaining, and sometimes disturbing dark comedy based on the real-life murder of wealthy Texas widow Marjorie Nugent (Shirley MacLaine). Jack Black stars, but this isn't one of his mainstream comedies; Bernie's story is told with a mix of seriousness and levity, a tone that may be hard for tweens and under to process, given that it all actually happened. There's a bit of swearing (including very infrequent uses of words like "s--t" and "f--k") and scenes of cruelty (emotional, with one character needling and bullying another).
Sexual
Content
Innuendoes abound, but no there's no action.
Violence
The movie revolves around a murder. Guns are fired, and a woman is shot from behind with a rifle (it's shocking rather than grisly). Earlier, she's shown berating, insulting, and generally emotionally abusing those around her. Since Bernie is a funeral director, there are some scenes where he's shown working on a corpse.
Language
Language includes infrequent uses of everying from "f--k" and "s--t" (used about once each) to "ass," "hell" and "goddamn."
Social
Behavior
Bernie is about a man who kills an elderly woman and stuffs her in a freezer and yet is still beloved by many in his hometown -- an iffy message at best. It's possible to draw the conclusion that it pays to be kind and neighborly so that you'll have others' support when you make mistakes. But Bernie still has to take responsibility for his crime.
Consumerism
One character has lots of money, and she uses it to buy cars and clothes and go on vacations. There's some talk of how she may have felt entitled to be nasty because of the distance money afforded her.
Drugs / Tobacco /
Alcohol
Some social drinking.
