When J.B. swerves to avoid a semi truck in the final chase scene, the shed he crashes through can be seen already wrecked in a previous shot.
During the chase where Susan Howard & John Saxon are being pursued by federal agents the pursuing car alternates between an undamaged to damaged right rear fender/tail light section several times during the chase. Funny thing though is there is nothing in the actual chase scene to explain the apparent damage.
in a couple of road scenes, you can clearly see tire tracks where a skid was either practiced or from a previous take.
Dot is supposed to be driving in the final chase scene but just after we see her driving & saying "hang in" there is a man with mustache seen driving the car towards the camera.
In some of the chase scenes, tire squealing sound effects can be heard when the cars are on dirt roads.
