Continuity mistake: [This will soon have an episode change from "Pilot" to "show generally"] During the show's opening credits for the entire run of the series, when Tony drives up to the NJ Turnpike toll gate, the lane 7 machine spits out a toll ticket, and Tony reaches for it. It then cuts to a close-up as Tony grabs hold of the toll ticket, but this ticket machine is now different; note all the stickers. The close-up was shot at another lane's ticket machine.
Continuity mistake: Tony gets out of the car near the start and there is no glass on the floor, when he calls Christopher over, broken glass on the ground has appeared.
