A man (Lou) punches another man, but the latter (Tyler Durden) laughs psychotically with each punch. The man (Tyler Durden) later jumps on the other man, continuing to laugh wildly while spraying and coughing up blood on him.
About 15 scenes of men involved in bare-fisted boxing matches: they punch each other in the face, ears and stomach and are sometimes thrown to the ground or against a wall; often they're surrounded by a group of cheering men. The participants in these fights nearly always have at least one very bloody facial cut or have blood on their clothing; we see many men with black eyes, bruised faces, bloody mouths and bandages on their faces.
The Narrator has a fantasy of a midair collision where we see an airplane's cabin destroyed and people and seats being sucked out of what's left.
A group of men ambush a man whom a man beats to the ground, the men wear ski masks and hold him hostage, pulling down his pants and duct-taping his mouth shut. They threaten to castrate him and he passes out from shock.
To intimidate his boss, the Narrator starts punching and flailing himself across his boss' office (and breaking a glass coffee table and some shelving units with his body in the process). We see shards of glass puncture his arm/hand along with blood on his shirt. He then walks away.
Tyler Durden gets in a fight with another man. Eventually it gets pretty brutal and bloody.
A man's forehead is stitched after a fight (we don't see the wound, but we see the doctor's hand sewing it up).
A man purposefully drives down the wrong side of the road and into oncoming traffic to prove his lack of fear and scare the others with him. He then drives faster and without holding onto the steering wheel, causing the car to crash into another car that's pulled over to the side. As a result, both roll over an embankment, injuring everyone inside.
Extremely brutal, bloody and disturbing fist-fight scenes throughout. They're very graphic, savage and realistic, and are more than enough to discourage anyone from beating up people.
Three men, who are police officers, turn on a suspect and threaten to castrate him with a knife. He is hauled onto a table and his pants removed. He manages to escape, however.
Man rips out tooth with his own hand, not bloody but the sound and act may be disturbing for some viewers.
R violence type: blood, gore, brutal and graphic.
Photo realistic violence, and very adult themes makes it a 16+ movie.
