One scene where you can see the naked back sides of men in prison.

Boxing violence, the 1966 murders that Rubin was falsely convicted of, a boy carries a switchblade knife.

Four people are shot (we see one shot in the head and one in the chest, with lots of blood visible); in several different scenes we see their bloody bodies slumped on a bar or lying on the floor in puddles of blood. A man who appears to be a pedophile and is trying to "pick up" a boy (see Sex/Nudity) is hit in the head with a bottle. He grabs the boy who threw the bottle and threatens to throw him off a ledge; the boy then stabs the man in the arm several times (no blood is visible) and runs away. We see three boxing matches with lots of punching (in two, we see men with swollen eyes, bloody noses and mouths and bloody facial cuts); all three end with one of the boxers being knocked out. We see news clips of police officers beating people with clubs, shoving a gun in the back of a man's neck and pushing people to the ground, presumably during civil rights demonstrations. A boy is dragged into a room by several police officers; one grabs his arm and verbally threatens him. A car crashes into a wall after one of its tires falls off (none of the passengers is injured). Something is thrown through two windows in a house. A man and woman briefly yell at each other. We see doctors with bloody gloves working on a man with an extremely bloody face.

26 or more uses f-bombs . Several racial slurs are uttered throughout the movie. some less offensives mild language including s-word

Some social drinking.

The prison and boxing scenes can be tense for younger audiences, as can Rubin's interrogation by nasty police detectives.
