Two death scenes take place involving a gun in someone's mouth. The first is sudden, and we see blood spray onto the wall and bed behind the victim. In the second instance, we hear the gunshot, and later see the bloody results.
Clones wear collars that can be activated when they rebel. In one scene, a waitress punches a customer, and the manager presses the button that sets the collar off. Her throat bursts open, causing blood to spurt everywhere. It is later revealed that all clones are eventually killed, and literally fed to the next generation of clones. The clones are killed by an (sort of) electric chair, decapitated (off screen), and then shipped around a factory to be conerted into foodstuff. We see thousands of hanging, bloody bodies without heads.
A futuristic chase takes place between Chang, Sonmi, and government agents. There are plenty of gunshots and explosions that cause roads and buildings to be destroyed. Chang shoots and punches out several agents while defending Sonmi.
Brutal fights take place between Zachary's tribe and Kona barbarians. A man has his throat slit (we see it from a distance), a young boy is shot and killed by a crossbow, and a village is destroyed. We see heads stuck onto pikes and burning houses and corpses. Meronym takes out several warriors with a plasma gun. Zachary viciously slits the throat of one of the barbarians, we see blood spurt.
There are several other scenes of violence throughout the film, some stronger than others, but none of them are very long. The camera watches a man's fall from the top of a skyscraper as he hits the ground, with blood and guts flying forth. Autua is seen being whipped, we see some bloody scars. A shootout and chase in San Francisco involves a violent car crash, a few mild wounds, and a man receiving several blows to the head from a wrench, causing blood to ooze. An airplane explodes, a man dies after being hit in the head with a trunk of gold (we see blood ooze).
A dog is shot off-screen.
Luisa, while driving, is forced off of a bridge into the water. For a while, its implied she drowned, but we see later- that she breaks the windshield and swims away safely.
A rather violent (yet comedic) bar fight causes a man's tooth to be dislodged. We see a keg smashed over someone's head, tables turned, and people mercilessly punched and kicked. Autua gets into a fight with the doctor in the hull of the ship, and at one point, bites the man to get him away.
