Revealing: In the barber shop scene at the end of the film, Agent Anderson terrorises Deputy Sheriff Pell (who has a full head of hair) with a razor blade. Anderson throws him across the room, but the person being thrown across the room has a mostly bald head.

Continuity: Anderson (Gene Hackman) visits Clinton Pell's wife and she's talking about Genesis 9, verse 27. In the first shot he's standing right behind her. In the next shot he stands on her left side. Then again right behind her.

Other: In one shot, during the lynching, the noose comes undone from the character's neck while he is hanging.

Deliberate "mistake": In the scene where the FBI agents are transporting Lester Cowans in a car and telling him all his friends have confessed, for about three seconds the scenery goes by backwards. For some reason, the shot is played in reverse.

Continuity: When the farmer's house is on fire and he goes to the barn to try and open the door, he is hit from behind. When they tie the rope around his neck and prepare to hang him, his forehead and face are bloody and I don't think he was ever hit directly in the face.

Continuity: When Gene Hackman is shaving Brad Dourif he cuts him on the right side of his face. Once Dourif is out of the chair, the cut is on the left side of his face.
