Continuity: When Rabbit and his mom's boyfriend were kicking each other's ass inside the Smith's trailer, Rabbit pushes or punches the boyfriend from the kitchen to the living room, breaking a small wooden post in a quick shot. A few shots later, when Rabbit returns to the trailer, the wooden post is intact. There was no time to fix it.

Continuity: In the opening scene, there is a zoom in of Rabbit's shoes, showing them dirty and worn out. In the next scene when Rabbit's on the bus home, his shoes are new.

Continuity: In the scene when Rabbit goes to his mom's trailer for the first time, he is wearing street shoes, but when he takes Lily in the trailer he is wearing boots.

Continuity: When Jimmy and Wink are walking to the bus stop, and Jimmy says "don't tell anyone I'm living back here man", they are just about to walk past a blue and white trailer. But when it cuts to the next shot with Wink saying "I heard you got caught out", they have walked about 15 feet past the trailer.

Continuity: When Vanessa is rapping outside New Detroit Stamping, one of her dreads is caught in her ear-ring. it goes from being trapped to not being trapped during the rap. It is trapped again in a later shot.

Factual error: It doesn't take 2 guys pushing buttons to make the press operate. OSHA establishes that a light beam be placed so that if anyone/thing tries to enter an unshielded area on a press it breaks the light beam and the press stops immediately, like an automatic E-stop. The press would never operate while someone is in the die pulling the part out so there would be no need for dual controls.

Continuity: When Poppa Doc is holding the gun to Jimmy's head, he first has it touching his jaw, then when Wink is begging him not to shoot Jimmy, the gun is just in front of his mouth, then when the shot cuts back to Jimmy, the gun is touching his jaw again.

Continuity: Before the opening battle scene, when Eminem is outside changing his top he asks for some privacy. At first his clean top is on one arm, then the shot changes and the top is laid out flat on the top of the dumpster. When the shot changes back, the top is on his arm again.
