In order to push the tattoo artist for information, Jimmy holds a tattoo machine up to the artist's eye while they question him. During the close up shots of the artist the tattoo machine is directly in front of his eye but every time the shot moves to Jimmy and Paul, the tattoo machine is being held away from him.
In the scene after they arrest Dave ('Sean William Scott'), and are driving in the car, Paul ('Tracy Morgan') can be seen talking on a Blackberry Pearl. In the first part the phone can be seen held correctly. When the camera switches to a view from over his shoulder. The phone is being held upside down.
When driving around in the Crown Victoria patrol car, the vehicle has LED lights in the grill, back window, and one dual light attached with suction cups in the front windshield on the dashboard. In later scenes, the dash light is missing.
Towards the end of the film when Jimmy arrives at Poh Boys house during a "shoot out" he has a white bandage on his right forearm, despite not incurring any injury to his arm earlier in the film. The injury to his arm actually occurred in a deleted scene with a fight with a waitress in the restaurant where they went for translation help.
At about 1 hour 4 minutes into the movie, an bird's eye view shot of Paul and Gabriela are seen lying in the bed. Paul is on the left. In the next shot, they look at each other and this time Paul is on the right.
When Paul interrogates Raul, Raul breathes on the mirror-glass, so it becomes hazy. Some people think that Jimmy draws a figure in the haze on the other side of the glass, though his side must be dry, but before he starts to draw, he is seen breathing himself on his side of the mirror-glass.
