Parents need to know that this movie has extreme graphic violence and non-stop profanity. The language used includes many exceptionally vivid British swear words, the literal meaning of which may not be familiar to some users. The characters are drug dealers (who generally themselves don't use drugs), and there's a generally lax attitude toward substance abuse of all kinds. There's one sex scene that is moderately explicit and brief non-sexual nudity.

Families can talk about how McElroy developed the plan that would allow him to achieve his dream (which is not fully revealed until the credit sequence). Why was that dream so important to him? Speaking of dreams, they might like to talk about what it was about this material that made Samuel L. Jackson want to produce and star in it.
