Revealing: During the whole movie any time someone is driving, the driver turns either way too much or not enough for the turn they are on. Even when they are driving straight, they turn the wheel as if they are going back and forth on the road in both lanes.

Revealing: In the chase scene, Milton Berle and Terry Thomas are actually driving two different blue '61 Chevrolets. Initially, they are in a rare Super Sport as evidenced by the crossed flags emblem on the rear seat speaker cover. Fortunately, the car they eventually crashed was the less desireable non-SS version (i.e. no crossed flags emblem present).
