One notable violent and also rather frightening scene in the film is when Wolverine is unleashed, where he slices and dices every man in his path, who are shooting at him. Bloody results are seen, especially in the aftermath. But nothing too exceptionally graphic. This sequence goes for nearly 2 minutes.
One character uses a long blade to slice open the neck of another character, whose open wound is shown clearly but quickly heals and is closed back up.
Moderate portrayals of violence with some details are depicted. Portrayals of violence also include some infliction of pain and injury but are never detailed, intense or prolonged.
The film contains several sequences of violence, where moderately impactful blows are portrayed, along with occasional details such as infliction of pain and injury.
In one scene, three men are decapitated by a mutant, but the depiction is not detailed, and partly obscured by a cloud of dust.
Another mildly impactful depiction of violence occurs when a person's leg is broken when he is kicked from the side of the knee joint. While there is no depiction of bloodshed, the injury is implied by the sound effects and the angling of the leg.
In addition, there is also a scene where a person is held by the neck and choked for a period of time.
Throughout the film, there are sequences of combat amongst mutants and between the mutants and humans, with occasional moderately impactful depictions of violence.
