The "good" guys think nothing of simply shooting and killing all bad guys, with no consequences. At one point, the main character even brags that having a son in the CIA will get him off the hook, no questions asked. Also, the father character practices "tough love" with his son, ridiculing him for having weaknesses and feelings. That said, they eventually do get closer, and McClane is persistent, if nothing else.
Constant, over-the-top action violence and destructive mayhem, including car crashes and helicopter crashes, falls from heights, hails of bullets, huge explosions, and dozens of dead bad guys. Some characters are shot graphically in close-up, sometimes in the head or other vital organs, with sprays of blood. Strangling, punching, helicopter battles. The "good guys" kill any and all bad guys without consequences. They're covered with bloody cuts and scratches throughout. One character removes a metal bar from another character's abdomen after he's been stabbed by it.
One female character's sex appeal is played up. She wears a leather motorcycle outfit in one scene and alluringly unzips the jacket. (No nudity shown.) A man caresses and nuzzles her while both are clothed. One scene takes place in a nightclub, with some dancing girls in skimpy outfits shown in the background.
"F--k" and "motherf----r" are used several times, as is "s--t." "Damn you," "Jesus Christ," "goddamn," "jerkoff," "a--hole," "ass," "crap," "scumbags," "bastards," "goddamn," "oh my God," and "hell" are also used. A grown son tells his father to "shut up."
In Moscow, Pepsi and Heineken signs are visible. Mercedes vehicles are prominent. A character mentions Bosco brand chocolate syrup.
Some bad guys are seen briefly smoking cigarettes. One scene takes place in a nightclub, with some background drinking suggested.
