After Messer's body is found, the A.U.S.A. says that a .32 caliber slug was removed from the body. However the pistol Dewey used was a Colt Mustang .380 ACP. In fact when Dewey is shown holding the pistol, pointed at Messer, a close-up of the pistol clearly shows "CAL .380" stamped on the breach end of the barrel.
As Dewey is running through the forest and down the mountain, the viewer sees the landscape full of scrub brush and Western White Pine trees. Neither of these flora are found within 2,000 miles of eastern Kentucky (filmed in southern California).
