Deliberate mistake: While Tony stands beside his car, the first assassin shoots at him, and when Tony dives into the front seat we see the car's dashboard. After struggling with the second assassin, when Tony crashes into the parked car, in the shot from inside the car, there are two issues: the car has a different style dashboard with no air vents, and the rearview mirror is missing; then it reappears.
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.
