The movie contains frequent intense action violence. It is often brutal, although there is minimal blood and gore. For example:

• After the sound of a gunshot, James runs downstairs to find his father lying on the ground dead and a man standing over him with a shotgun. Bone-like knives come out of James’s fists. He charges at the man and plunges both of his knife hands into the man’s stomach, killing him.
• The film’s opening credits include a montage of scenes from wars. This includes explosions that send people flying through the air, soldiers being shot in the chest, soldiers being hit in the chest by cannonballs, soldiers fighting in trenches, and soldiers being shot in the chest by machinegun fire.
• During the Vietnam War, Victor rough-handles a woman. He throws her on a bed in a village hut, apparently intending to rape her. After being stopped by his fellow soldiers, he goes berserk, shooting and killing the soldiers who interrupted him. Logan tries to stop the killing. Victor and Logan finally submit when they are surrounded by a ring of soldiers all pointing guns.
• A mutant pulls out two handguns. With superhuman speed and accuracy, he shoots and kills armed men behind a barricade. The mutant then leaps over the barricaded gate and continues to shoot armed men until all are dead. Another mutant sticks his fist into the gun barrel of a tank, causing the tank to explode.
• A mutant holding a samurai sword walks out of an elevator into a hailstorm of machinegun fire. The mutant swirls his sword in a blur of motion, using the sword to deflect bullets. Some of the deflected bullets hit the people with the machineguns. The mutant uses his sword to stab, cut and slice his way through the remaining armed men until only one remains.
• A group of African villagers kneel down with their hands behind their heads while surrounded by a squad of mutant solders. Victor grabs the head villager’s neck and twists it.
• Logan finds Kayla lying on the ground dead, her chest and neck covered with blood. He holds her dead body in his arms and screams in despair.
• Logan and Victor fight each other in several scenes. Logan extends his knife blades and Victor extends his claws. They slash, claw, hit and throw each other around. We hear the sounds of bones breaking. Logan stabs Victor through the hand and in the chest with his extended bone knives. Victor sinks his claws into Logan’s chest and shoulder. In one fight, Victor picks up Logan and throws him into the path of a speeding truck. Logan rolls over the bonnet of the truck and lands hard on the ground. In another scene, Logan lies on a train track. Victor walks up to him and stamps down on his extended bone knives. The knives break off and Logan screams in pain.

Wolverine runs up a hill and leaps onto the helicopter, using his knives to slice off the helicopter’s blades. The helicopter crashes. We see one of Stryker’s mutant henchmen wounded and partially hanging out of the helicopter’s windscreen. Wolverine walks away from the helicopter, striking his blades on the ground and creating sparks that ignite spilled fuel. The helicopter explodes in a ball of flames.
• Wolverine fights a fellow mutant called the Blob, an extremely obese man. Wolverine repeatedly hits the Blob in the face and the stomach, and the Blob throws Wolverine out of the boxing ring. They punch each other in the head, stomach and back. The Blob head-butts Wolverine, and we hear the sound of a loud metallic clunk. Wolverine slams his fist down on top of the Blob, and the Blob collapses.
• Victor chases a teenage mutant boy through a school building. When Victor catches the boy, he knocks the boy to the ground. The boy’s glasses are knocked from his head and laser beams shoot out of the boy’s eyes, cutting through the walls of the school. Victor holds the boy’s head while a second man injects a tranquiliser into the back of the boy’s neck. The boy falls unconscious.
• Victor punches his hand through another mutant’s stomach. Victor says, ‘I can feel your spine’, and jerks his hand out. We hear bones cracking, and the mutant falls to the ground.

As Weapon XI falls, his head separates from his body while laser beams shoot from his eyes.
