The film encourages viewers to think about the topics that the main characters discuss, but there really isn't any positive takeaway amid the violent mayhem.
Hit men frequently discuss murder. Images (flashbacks as well as present time) show brutal, bloody, loud violence. Weapons include guns, knives, and fists; effects include the decimation of heads and limbs. A young boy is shot in the head (bloody image recurs, haunting the killer); a man falls off a tower, with explicit results. Discussion of suicide, and one man almost shoots himself in the mouth. Finale features repeated shooting, foot chase through city streets, lots of blood, and visible pain.
Brief sex scene between Ray and Chloe (non-explicit passionate roll on bed); Chloe appears in bra and panties. References to hookers (a prostitute appears kissing a client); at a party, couples tongue kiss. Primary couple kisses passionately near the end.
Lots of language, including 100+ uses of "f--k" and several of "c--t," plus fewer uses of "s--t," (several with "hole," a couple with "horse"), "prick," "a--hole," "hell," and "p---y." Derogatory terms like "poof" and "fag" are also used, and there's heated discussion of racism.
Frequent smoking and drinking (liquor, beer, wine), in cafes, pubs, and hotel room; several scenes show drug consumption (snorting cocaine); pills discovered in a hiding place; repeated references to drugs (cocaine, heroin).
