When Sharr buries Bobby he is seen putting two locks on the box before covering it with dirt. When Hunter uncovers the buried box there are no locks on it, he simply lifts the lid up.
During the shootout outside the Red Circle Bar, one of the bad guys jumps into the gold Oldsmobile Cutlass Ciera. As Hunter shoots the other gunman, you can hear the tires squealing, sounding as if the car speeds away, yet the car can be seen motionless. In the next shot, the car is gone.
