Common Sense Note
Parents need to know that this dull romantic comedy finds humor in the violence associated with being an undercover assassin. Characters shoot, stab, and strangle each other throughout the movie, which doesn't shy away from showing the bloody consequences. The movie's premise rests on the idea that a man hasn't been completely honest with his wife about a big part of his former life, but that's not explored. (Neither is the idea of killing as a profession.) There's some swearing (including "f--k" and s--t"), but nothing over the top, plus several sexual innuendoes. One character drinks excessively (and she's actually the funniest of them all).
Lots of sexual innuendoes; Heigl's character is seen in her underwear. She and her husband flirt and kiss often. An older woman shows off her cleavage to a younger married man. Frank discussion of a married woman's sex life.
Consider the title: For a rom-com, Killers is laden with bone-crunching fistfights and guns-ablaze sequences (and their fairly bloody aftermaths). The lead character is an assassin, after all, and off the bat, he's shown at his "job." One character gets impaled by a chandelier (her remains are briefly visible); another's car is skewered by metal rods at a construction site while he's still in it (we don't see his body).
Not excessive, but "s--t" and "f--k" do pop up.
Killers is a strange concoction: Murder is played for laughs, but since the film's not very funny, how does that leave the body count then? Jen is such a caricature of a weak, immature woman, that she would be offensive if the movie weren't overall so lame. Still, the movie does attempt to explore the idea of honesty in a marriage, and its importance to making a relationship successful.
Logos for Ford, Ferrari, Maalox, and other products clearly visible.

Some social drinking, plus one character who's clearly a lush (and her drinking is played for laughs). Nearly every time she's onscreen, she's fixing herself a sizable cocktail. Another character passes out from knocking back too many drinks on her first date with a guy who, curiously, finds the whole debacle charming (only in the movies.). A few guests get drunk at a party, and one of them leaves the hosts wondering if he's able to drive (though they let him go).
