Plot hole: Diamond is in a very small town in the middle of rural nowhere, and it's the middle of the night. His car has just been wrecked, driven over a cliff by the bad guy. Yet on the same night, in the cafe at the end, he offers George a ride - for that same night - to New York. (00:25:30)
Visible crew/equipment: Diamond parks outside the apartment house, and when he opens the car door, it mirrors several stage lights and reflectors.
