Other mistake: When the driver of the ZR1 corvette changes gears the emergency brake lever is visibly up.
Character mistake: Lewis Dinkum tells Deputy Mike Figuerola it's only a .50 cal round that hit him in the shoulder. The rifle he was shot with was a Blaser R93 LRS2 which fires a 338 Lapua round. A .50 pretty much would have torn him in half.
Continuity mistake: When Ray drives through the fields, the headrests inside the Camaro ZL1 show SS instead of ZL1.
