Continuity mistake: Joe is looking through his yearbook while Marie chats with the old headmistress. He finds the page with Adrian's photo. At first, the name under the photo is Adrian Pryce. In the closeup shot, it now reads Adrian Doyle Pryce. (01:12:20)
Factual error: When Joe is first imprisoned in 1993 he's flicking through channels and passes a scene from Xena: Warrior Princess. Xena didn't air until 1995.
Continuity mistake: When Joe is fighting the high school footballers, he picks up the football boot by the heel with the toe pointing forward. When the camera cuts to the screaming girl he is holding the boot the other way around, with the toe pointing backwards. The camera cuts back, and the boot toe is facing forward again. (00:36:00)
Character mistake: When Joe and Marie are going over files in the old school, Joe finds a staff letter announcing the enrollment of Amanda Pryce. The top of the letter is dated 1984. However, Joe then proceeds to ask Marie to search for Amanda's file, and tells her to search for the year 1986.
Suggested correction: It's possible the incident happened up to 2 years after her enrollment (starting as a freshmen and the incident being when she was a sophomore or junior).
Continuity mistake: After the "Single Shot" fight sequence, watch closely as the camera cuts and Joe is stabbed in the back. The background (and the beaten-up henchmen strewn about on the floor) completely changes between shots. A section of the fight was cut out by the studio for pacing reasons, causing the mistake.
Continuity mistake: During the ending, when Joe is seen burning one of the letters he had written Mia, when the camera cuts from a medium shot to the closeup of the letter burning, the handwriting on the envelope is slightly different, and the size/position of the fire has also changed.
