Some scenes of heavy, brutal violence. In a 2 hour movie, there is maybe 10 minutes of violence, with the majority being saved for the last maybe 30-45 minutes. The violence is very realistic and grisly however but consists of two only partially shown scenes with teeth extraction, the famous hammer fight and a hand to hand combat scene.
The violence is very disturbing and is often hard to watch.
A man is seen with a bloody towel in his mouth after having his teeth extracted. He is thrown into a crowd of men.
Early into the movie, Dae-Su get into a fight with some young guys for taking a cigarette from one of them. No blood.
It should be noted that while the torture, self-harm and murder scenes are disturbing and often graphic, the hand-to-hand combat or action sequences are almost always kept to a non-fatal and PG-13 level. The infamous hammer fight scene and the other scenes of fighting are not bloody or gruesome at all.
This is not a movie for everyone, regardless of age. Some people may find elements very hard to watch and upsetting.
R violence type: blood, brutal and graphic.
A man attempts suicide by cutting his wrist in a couple scenes, plenty of blood is seen on the ground. Only the aftermaths are shown, but the man has prominent scars on his wrist for the rest of the film.
Stock footage of disasters like 9/11 are shown for effect in one scene.
A man commits suicide with his dog by jumping off a building. He lands on a car, startling several nearby people, and his body along with his dead dog is seen.
There is a graphic torture scene where a man rips out several of another man's teeth with the claw of a hammer as a form of torture. We see an extreme close-up shot of one of his teeth being pulled which seeps blood, and then we see him ripping down on the hammer and bloody teeth falling onto a keyboard. The scene is brief and only lasts for a few seconds but is hard to watch.
In a long, realistic fight scene, a man hits several other men with a hammer while they hit him with several blunt weapons. The men are seen in various stages of pain from blunt force trauma. At one point, he is stabbed in the back and beaten up, but he wakes up and takes them all down. The scene is shown in distance.
A man attempts to rip out another man's teeth (in revenge for the man doing it to him) but gets stopped before he can. He then hits the man in the head with a bat, and he's seen in great pain. The attempted victim then threatens to cut of the others hand for molesting a woman.
A man is brutally murdered by being stabbed to death with a broken disk. The camera angles emphasize the strong impact of the killing but also obscure graphic detail. A small amount of blood is seen squirting and a lot is on the killer.
A man's severed hand is seen briefly. No blood, but a woman faints.
A man gets into a fight with another man, he's violently thrown about a room, against several glass objects. Eventually, the second man is stabbed in the ear with a pair of scissors, destroying his eardrum. Blood is seen leaking out of his ear while he attempts to stab the first man in the neck. He's then shot in the head before he can kill the first man. This is very bloody and fairly graphic.
A man is seen with some blood on him after another man is shot and killed in front of him.
A man shoots himself in the head, this is graphically seen with lots of blood and a bullet wound on his head. This comes absolutely out of nowhere and is extremely startling.
Infrequent but very strong, however there are two scenes which are quite graphic but they don't last for more than just a couple of seconds and the worst bits are not shown.
