Other mistake: When Cam get his paycheck you can see his home address as 49-54 39th Street Queens, NY 11101. When Cam gets picked up by Miller in his blue van the logo on the door says M M CONST 49-54 39th Street Queens, NY 11101. It is the same address where Cam lives. (00:03:55 - 01:03:20)
Factual error: Cam finishes tightening the alternator on his Pontiac, jumps in and starts the car. He pulls the automatic gear selector into drive, and the engine stalls. Without returning the selector back to "Park" or "Neutral" he attempts to start it. The motor grinds and grinds, however, when the vehicle is in gear, the starter is disabled.
