Continuity: In the scene where Monty is about to leave for jail, Naturelle goes to get ice for him. She pulls open a drawer and grabs a quart size Ziplock bag and starts to fill it with ice. They cut to Monty and when they cut back to Naturelle she's filling a gallon sized Ziplock bag.

Factual error: Otisville Prison was not in the direction Monty's father was driving. He said he would take the Henry Hudson Parkway north and later continue on the Taconic Parkway. The Taconic runs due north toward Massachusetts on the east side of the Hudson River. Otisville is 30 miles west of the Hudson.

Continuity: In the beginning of the movie where Monty is looking at his old school photo, look closely at his beard. In the next scene when he's in the classroom talking to 'his old friend' his beard has a completely different shape.

Visible crew/equipment: Monty and his father get into the car to go to the prison. When the father says "Them hooligans sure gave you a licking" a red mike appears at the top.

Continuity: In the scene with the V.I.P section at the dance club, Phillip Seymour Hoffman polishes off his champagne. Immediately after, Edward Norton goes to fill Hoffman's glass for a toast, but the glass is already half full.
