Revealing mistake: At 1:20:25 - Just after Joe and Bobby have returned to the plane to pick up the gold, we see 2 ground crewmen walking across the front of camera. One of them stares directly at the camera for a half-second, before shaking his head away, so as not to look like he's staring at the camera. (Danged extras. .). (01:20:25)
Visible crew/equipment: There is a scene where the main characters are robbing an airplane on a deserted runway. In one shot, they move to a wide view of the entire plane - you can see quite clearly in the background a van and several crew members watching the filming. (they are facing the camera). In the next shot all those people are gone.
Continuity mistake: When Joe and Bobby convince the state trooper that everything is ok, we see the State trooper heading back to his car and reaching to his mic on his shoulder. The camera angle changes to a view from the side mirror of the car and we can see the state trooper walking to his car and reaching to his mic on his shoulder again.
Continuity mistake: In the first robbery scene we can see a taxi suddenly braking after the explosion. In the first shot the taxi comes clearly to a halt, in the next shot taken from a different angle it smashes into a parked car.
Audio problem: When Mickey asks Joe "don't you want to hear my last words?" we hear the sound of a pump shotgun being racked, but Joe has a double-barreled shotgun - there wouldn't be any cocking sound.
