FLAWLESS is a very good movie for adults and teens. It's probably okay for preteens too, but they might be bored by it, since it is set up much like a Hitchcock thriller instead of James Bond.
There is one "f**k" in addition to one "d**n" and one "piss". There is lots of drinking and smoking, though none of it is promoted. Though both of the main characters have motives for stealing the diamonds (he becuase of his late wife and her because of her mistreatment by co-workers), make sure kids understand that that doesn
t make it right.
