Visible crew/equipment: When Cain is driving down the street just after he robbed the guy for his daytons, when the camera pans up, just before it switches to Cain's view you can see the reflection of the camera on the very bottom of the bonnet (hood).
Continuity mistake: Check the position of the coke when the main character is talking to the teacher in school. The main character is holding the coke in his hands and in the next shot it's on the table of the teacher.
